Top 5 Best Oilfield Invoice Factoring Companies

Running an oilfield business means managing expensive equipment, high labor costs, and the constant pressure to keep operations moving. But one of the industry's biggest challenges is simply getting paid on time. Long payment terms can leave oilfield service companies struggling to cover payroll, maintain equipment, or take on the next contract while completed invoices remain unpaid.

According to the Federal Reserve's 2024 Small Business Credit Survey, 51% of small businesses cite uneven cash flow as a top financial challenge. In the oilfield sector, where operating costs are high and large operators often control payment timelines, that challenge can be especially difficult.

Invoice factoring offers a practical way to close the gap. Instead of waiting weeks or months for customers to pay, oilfield companies can sell their unpaid invoices to a factoring company and receive cash within days.

However, not every factoring provider is equipped for the demands of the oil and gas industry. The wrong partner may come with hidden fees, restrictive contracts, or funding limits that make growth more difficult.

The five best oilfield invoice factoring companies are FundThrough, Integra Funding Solutions, Mazon Associates, Gulf Coast Business Credit, and SB Factoring. FundThrough leads the list as North America's largest AI-powered factoring platform, offering unlimited funding, 100% advance rates, and direct integration with Enverus OpenInvoice.

In this article, we compare these five providers, explain what to look for in an oilfield factoring company, and help you find the right fit for your business.

What Is Oilfield Invoice Factoring?

Oilfield invoice factoring is a financing tool where an oilfield service company sells its outstanding invoices to a third-party factoring company in exchange for a cash advance, typically within a few days. The factoring company then collects the full invoice payment directly from your customer.

The key difference between factoring and a traditional loan is that factoring is not debt. You are simply unlocking money you are already owed, faster. Your customer's creditworthiness matters more than your own, which makes it accessible for newer businesses or those with limited credit history.

Why Oilfield Companies Struggle With Cash Flow

The oilfield industry operates on long payment cycles. Large oil and gas operators often impose net 60 or net 90 terms on their service vendors, and in some cases payment takes even longer due to billing disputes or administrative delays.

At the same time, oilfield service companies face high upfront costs:

• Fuel and transportation
• Equipment rental or purchase
• Labor and crew wages
• Materials and supplies for large projects
• Insurance and compliance costs

This gap between money going out and money coming in creates cash flow pressure that can prevent a business from taking on new work, hiring staff, or meeting payroll. Invoice factoring bridges this gap by converting outstanding receivables into immediate working capital.

How Does Oilfield Invoice Factoring Work?

The process is straightforward and typically faster than any bank financing option.

Submit Your Invoices

After completing work and issuing invoices to your oil and gas customers, you submit those invoices to the factoring company.

Invoice Verification

The factoring company verifies the invoices and checks the creditworthiness of your customer. This step typically takes hours to a few days.

Receive Your Advance

Once approved, you receive a cash advance, usually between 80% and 100% of the invoice value, directly into your business bank account.

Customer Payment

Your customer pays the factoring company directly on the original invoice due date.

Receive the Remaining Balance

After your customer pays in full, the factoring company sends you the remaining balance minus their fee.

What to Look for in an Oilfield Invoice Factoring Company

Not all factoring companies specialize in oil and gas. Here are the key factors to evaluate before signing up:

Advance Rate

The advance rate is the percentage of the invoice value you receive upfront. Higher is better. Look for companies offering 90% to 100% advance rates.

Fee Structure

Factoring fees, also called discount rates, typically range from 1% to 6% of the invoice value. Watch out for hidden fees such as application charges, processing fees, monthly minimums, or early termination penalties.

Oil and Gas Industry Experience

An oilfield factoring company that understands the oil and gas billing cycle, lien waivers, and joint interest billing will provide better service and fewer surprises than a generalist factoring firm.

Contract Flexibility

Some factoring companies require long-term contracts or demand that you factor all your invoices. The best companies let you choose which invoices to fund and operate on flexible or month-to-month terms.

Speed of Funding

In the oilfield business, days matter. Look for companies that can fund within 24 to 72 hours of approval.

Recourse vs. Non-Recourse Factoring

With recourse factoring, you are responsible for buying back the invoice if your customer does not pay. With non-recourse factoring, the factoring company absorbs that risk. Non-recourse typically comes at a slightly higher fee but offers greater protection.

Technology and Integrations

Modern factoring platforms that integrate with accounting tools like QuickBooks or industry platforms like Enverus make the entire process faster and less manual.

The 5 Best Oilfield Invoice Factoring Companies

1. FundThrough

FundThrough is our top pick for oilfield businesses because it combines flexible invoice funding with technology built around the way oil and gas companies actually invoice and get paid. FundThrough has funded thousands of oil and gas suppliers and works directly with Enverus OpenInvoice, making it particularly useful for oilfield service companies already billing major operators through the platform.

One of FundThrough's biggest advantages is its unlimited funding model. Instead of working with a fixed credit limit, businesses can access as much funding as they have in eligible approved invoices. That matters in oil and gas, where a growing contractor can quickly move from smaller invoices to multi-million-dollar projects.

FundThrough also offers advance rates of up to 100%. Rather than receiving 75% to 90% upfront and waiting for a reserve to be released later, eligible businesses can put the full invoice value to work immediately, minus the factoring fee.

Pricing is also more transparent than many traditional factoring arrangements. Typical fees currently start at 1.9% per 30 days, with rates of 1.9% to 2.9% per 30 days for businesses with less than $1 million in outstanding invoices. Businesses above $1 million receive custom pricing. FundThrough shows the cost before an invoice is funded and does not add hidden fees.

Businesses can also choose which eligible invoices and customers they want to fund rather than committing their entire accounts receivable. There are no ongoing funding minimums or fees simply for keeping an account open.

Key Features:

• Up to 100% advance rates
• Unlimited funding based on eligible approved invoices
• Direct integration with Enverus OpenInvoice
• QuickBooks and other accounting platform integrations
• AI-powered invoice verification and funding processes
• Choose which eligible invoices and customers to fund
• No requirement to factor your entire accounts receivable
• No hidden fees
• Transparent pricing published online
• Funding available within 24 hours after first funding
• Dedicated account management
• Accounts receivable collection support

Factoring Fees: Typically 1.9% to 2.9% per 30 days for outstanding invoices below $1 million, with custom pricing available for $1 million or more.

Best For: Oilfield service companies that want scalable funding, high advance rates, transparent pricing, and technology that integrates directly with oil and gas invoicing workflows.

Pros:

• Up to 100% of the invoice value available upfront
• Unlimited funding based on eligible invoices
• No traditional reserve holdback when receiving a 100% advance
• Direct Enverus OpenInvoice integration
• Flexible invoice-level funding
• No obligation to factor every invoice
• No ongoing funding minimums
• Transparent pricing available before funding
• No hidden fees
• Fast, technology-enabled application and verification process
• Funding within 24 hours after first funding
• Dedicated account management
• Accounts receivable collection support
• Extensive experience with oil and gas suppliers
• Available to businesses in the U.S. and Canada

Cons:

• Funding is designed for eligible B2B and government invoices rather than consumer invoices
• Invoices must generally be for completed work and issued to creditworthy customers
• Invoice eligibility can be affected by existing liens or disputes

FundThrough is particularly strong for growing oilfield companies because the funding available can scale alongside their invoices. Instead of returning to a lender whenever a fixed credit limit becomes too small, businesses can continue accessing working capital as their eligible receivables grow.

For companies managing large operator invoices, long net terms, and increasing project costs, that combination of unlimited funding, up to 100% advances, flexible invoice selection, and direct OpenInvoice integration makes FundThrough the strongest overall option on this list.

2. Integra Funding Solutions

Integra Funding Solutions provides accounts receivable factoring specifically for oil and gas service businesses and is a division of T Bank, N.A. Its oilfield team works with companies across major U.S. basins including the Permian, Eagle Ford, Bakken, Haynesville, Marcellus, and others.

Integra has experience funding drilling and completion companies, trucking and hauling businesses, equipment rental companies, pipeline contractors, and other oilfield service providers. It also works with field tickets and master service agreements and can accommodate businesses with significant customer concentration.

Once an account is established, approved invoices submitted before Integra's cutoff can receive same-day funding. However, oilfield advances are typically around 85% to 90% of invoice value, with the balance released after the operator pays.

Key Features:

• Specialized oil and gas factoring team
• Bank-backed through T Bank, N.A.
• Same-day funding after account setup
• Experience with MSAs and field-ticket invoices
• Works with high-concentration accounts
• Available across all 50 U.S. states
• Dedicated oil and gas specialists
• Experience across major U.S. oilfield basins

Factoring Fees: Custom pricing; specific rates are not published online.

Best For: U.S. oilfield service companies that value specialized underwriting and the backing of a bank-owned factoring provider.

Pros:

• Strong oil and gas specialization
• Bank-backed funding platform
• Same-day funding available after setup
• Experience with major oilfield basins
• Handles field tickets and MSAs
• High customer concentrations may be accepted
• Dedicated oil and gas team
• Nationwide U.S. coverage

Cons:

• Typical oil and gas advances are around 85% to 90%, leaving part of the invoice unavailable until payment
• Initial oilfield onboarding typically takes 3 to 5 business days
• Factoring rates are not published online and require a custom quote

Integra is a strong alternative for companies that value traditional oilfield underwriting expertise and a bank-backed funding relationship. Businesses that prioritize receiving as much of the invoice as possible upfront, however, may prefer a provider offering advance rates closer to 100%.

3. Mazon Associates

Mazon Associates has been providing receivables financing since 1976 and has decades of experience working with oil and gas businesses throughout Texas and the Southwest.

Its oilfield factoring service covers a wide range of businesses, including drillers, crude haulers, equipment rental companies, pipeline contractors, water haulers, well servicing companies, and other oilfield service providers.

Mazon offers flexible month-to-month contracts, no application fees, no monthly minimums, and the ability to choose which invoices to factor. Once a client is established, invoices submitted before the daily cutoff can receive same-day funding.

However, Mazon's funding structure differs significantly from FundThrough's. It generally holds a reserve of 10% to 20% of the invoice and normally operates on a recourse basis.

Key Features:

• Providing factoring since 1976
• Long history serving oilfield businesses
• Same-day funding available for established clients
• Month-to-month contracts
• No application fees
• No monthly minimums
• Selective invoice factoring
• Accounts receivable and collection support

Factoring Fees: 2% to 5% factoring fee plus a 1% monthly finance or interest charge on outstanding invoices.

Best For: Oilfield businesses, particularly in Texas and the Southwest, that value a traditional relationship-driven factoring company with decades of industry experience.

Pros:

• Extensive history in oil and gas factoring
• No application or startup fees
• No monthly minimums
• Month-to-month contracts
• Select which invoices to factor
• Same-day funding available after setup
• Accounts receivable management included
• Credit monitoring services available

Cons:

• Factoring fees range from 2% to 5%
• Additional 1% monthly finance or interest charge applies to outstanding invoices
• Holds a 10% to 20% reserve until the customer pays
• Normally provides recourse factoring, meaning the client remains responsible if the customer does not pay
• Requires a first-position lien on invoices while the business is a client
• Initial funding generally takes 3 to 5 business days
• Same-day funding requires invoices to be submitted before the morning cutoff
• Customer credit reviews may result in limits on individual invoices

Mazon remains a credible choice for companies that prefer a long-established factoring relationship. Businesses should compare the complete cost carefully, however, because the factoring fee, monthly finance charge, and reserve structure can all affect how much cash is available and the ultimate cost of funding.

4. Gulf Coast Business Credit

Gulf Coast Business Credit is the factoring and asset-based lending division of Gulf Coast Bank & Trust Company. It serves businesses nationwide and has a dedicated oil and gas practice focused on accounts receivable financing.

Its oil and gas services are designed for companies that need working capital for expenses such as payroll and new contracts while waiting for customers to pay. GCBC also provides credit reviews, collection assistance, and accounts receivable servicing.

Established clients can receive funding on the same business day. However, GCBC typically advances between 75% and 90% of the invoice upfront. The remaining balance is held until the customer pays and is then released minus applicable fees.

Key Features:

• Dedicated oil and gas factoring practice
• Bank-backed through Gulf Coast Bank & Trust Company
• Same-day funding available
• Nationwide service
• No monthly minimums
• No long-term contracts
• Credit reviews available
• Collection and accounts receivable assistance

Factoring Fees: Specific rates are not publicly listed.

Best For: Oil and gas businesses looking for a traditional bank-backed factoring company with accounts receivable support.

Pros:

• Specialized oil and gas experience
• Backed by a bank
• Same-day funding available
• No monthly minimums
• No long-term contracts
• Nationwide coverage
• Collection assistance available
• Credit review services available

Cons:

• Typical advances range from 75% to 90% of invoice value
• A portion of the invoice remains unavailable until the customer pays
• Specific factoring rates are not published online
• Lower advance rates can leave businesses with less immediate working capital than providers offering up to 100%

GCBC may appeal to companies looking for a more traditional bank-backed factoring relationship. For businesses with large oilfield invoices, however, the difference between receiving 75% to 90% upfront and receiving up to 100% can represent a significant amount of working capital.

5. SB Factoring

SB Factoring focuses heavily on oilfield invoice factoring and works with businesses such as trucking companies, drillers, pipeline service providers, equipment operators, and other oilfield support companies.

Its primary appeal is speed. SB Factoring advertises quick application processing and funding after invoices are approved, along with advances of up to 95% of acceptable accounts.

Because of its oilfield focus, the company is familiar with the cash flow challenges created by Net 30, Net 60, and Net 90 payment terms.

Key Features:

• Strong focus on oilfield factoring
• Advances of up to 95%
• Fast application processing
• Same-day or next-day funding advertised for approved invoices
• Accounts receivable management
• No funding minimum advertised
• Personalized service

Factoring Fees: Specific factoring rates are not publicly listed.

Best For: Smaller oilfield companies that value a specialized provider and prioritize fast invoice funding.

Pros:

• Oilfield-focused factoring
• Advances up to 95%
• Fast application process
• Quick funding after approval
• Accounts receivable management
• No funding minimum advertised
• Personalized service

Cons:

• Maximum advertised advance of 95% is below providers offering up to 100%
• Specific factoring rates are not published online
• Funding limits are not clearly published
• Published approval rates differ across the company's website
• Funding timelines also vary across pages, with references to same-day, 24-hour, and 48-hour funding

SB Factoring can be a useful option for oilfield businesses that prioritize a specialized provider and a fast process. Businesses comparing providers should ask for the complete fee structure, funding limit, advance rate, and expected funding timeline in writing before making a decision.

Oilfield Invoice Factoring Companies Compared

Who Should Use Oilfield Invoice Factoring?

Invoice factoring is not just for companies in financial trouble. It is a strategic cash flow tool used by oilfield businesses at all stages of growth. Here is who benefits most:

Oilfield Service Contractors

Drilling, completion, and well servicing companies that work on large projects with long payment cycles are ideal candidates for factoring.

Equipment Rental Companies

Rental companies that supply equipment to oil and gas operators often wait 60 to 90 days for payment despite having ongoing maintenance and fleet costs.

Oilfield Transportation and Logistics Companies

Trucking and logistics providers in the oilfield sector need steady cash flow to cover fuel, driver wages, and vehicle maintenance between invoice payments.

Staffing Companies Serving the Energy Sector

Companies that supply contract labor to oil and gas operators face the challenge of paying workers weekly while waiting 60 or 90 days to collect from clients. Factoring makes this manageable.

Small and Mid-Size Operators

Smaller oilfield businesses often cannot access traditional bank lines of credit. Invoice factoring provides working capital based on the strength of their customers' credit, not their own.

Pros and Cons of Oilfield Invoice Factoring

Pros

• Fast access to cash: Turn unpaid invoices into working capital within days, not months.
• No new debt: Factoring is not a loan. It does not show up as liability on your balance sheet.
• Approval based on customer credit: Your own credit score is less of a barrier compared to bank financing.
• Outsourced collections: The factoring company handles collections, freeing your team to focus on operations.
• Supports growth: Access to working capital lets you take on larger contracts without waiting for existing ones to pay out.
• Flexible and scalable: Fund only what you need, when you need it.

Cons

• Cost: Factoring fees reduce your total invoice revenue. For high-volume businesses, this adds up and should be weighed against the value of faster access to funds.
• Customer notification: In most cases, your customers will be notified that their payment should go to the factoring company, which changes the collection dynamic.
• Recourse risk: With recourse factoring, you are on the hook if a customer does not pay.
• Not ideal for every invoice: Factoring works best for invoices issued to creditworthy customers. If your customer base has weak credit, approval rates may be lower.

How to Choose the Right Oilfield Factoring Company

Match the company to your volume and contract size.

If you regularly deal with multi-million-dollar invoices, you need a factoring company with no funding caps like FundThrough. A company with strict credit limits will become a bottleneck.

Ask for a full fee breakdown before signing.

Request a complete list of all potential charges including application fees, ACH fees, wire fees, monthly minimums, renewal fees, and any penalties. A reputable company will provide this upfront.

Understand the contract terms.

Some factoring companies require a minimum volume commitment or a minimum contract length. Look for month-to-month flexibility and the ability to choose which invoices you factor.

Check for industry-specific experience.

An oilfield factoring company that understands joint interest billing, AFEs, and master service agreements will serve you better than a generalist.

Read reviews and ask for references.

Look for testimonials from other oilfield businesses. Verify response times, communication quality, and how disputes are handled.

Evaluate technology integrations.

If your business uses QuickBooks or an oilfield data platform like Enverus, choosing a factoring company with direct integrations reduces manual work and speeds up the funding process.

Frequently Asked Questions

How much does oilfield invoice factoring cost?

The cost of oilfield invoice factoring typically includes a discount rate, or transaction fee, that ranges between 1% and 6% of the invoice value. This fee is deducted from your invoice amount in exchange for receiving cash quickly instead of waiting on net terms. Some factoring companies also layer in additional charges such as application fees, processing fees, monthly minimums, wire fees, or late payment penalties, which can significantly increase the real cost.

FundThrough takes a different approach. Instead of a complex fee schedule, FundThrough charges a single flat fee per invoice with no hidden costs. You receive 100% of your invoice value upfront, minus that one transparent fee.

There are no surprise charges, no monthly minimums, and no fees stacked on top of each other. For oilfield companies dealing with large invoices, this straightforward pricing model makes it much easier to calculate the actual cost of factoring before you commit.

How long does it take to get approved and receive your first factoring payment?

The timeline with FundThrough is significantly faster than traditional financing. The initial application is straightforward: you sign up using your email address or by connecting your QuickBooks Online account or Enverus OpenInvoice platform.

From there, FundThrough uses AI-powered automation to verify your invoices and customers, which speeds up the process considerably compared to manual, paper-based factoring operations.

After your first funding is approved, you will see cash in your bank account within 24 hours of that approval. The first funding typically takes a few business days to complete as FundThrough verifies your account, invoices, and customer information. Once that initial setup is done, subsequent fundings move much faster since your account and customers are already on file.

Is there a contract or minimum commitment with an invoice factoring company?

This varies by factoring company, and it is one of the most important questions to ask before signing up.

Some factoring companies require long-term contracts, minimum monthly volumes, or demand that you factor all of your invoices rather than letting you choose. These restrictions can limit your flexibility and lock you into arrangements that do not fit how your oilfield business actually operates.

FundThrough offers flexible, commitment-free funding. You are not required to factor all of your invoices or sign a long-term contract. You decide which invoices to submit for funding, when to use the service, and how much funding to access at any given time.

This on-demand model is particularly well-suited for oilfield companies whose cash flow needs vary from month to month depending on project size, seasonal demand, and payment cycles.

Can oilfield companies choose which invoices to factor?

Yes, and this flexibility is one of the key features that sets FundThrough apart from more rigid factoring arrangements. With FundThrough, you are in full control of which invoices you submit for funding.

If you only need to factor a few large invoices to cover payroll or ramp up for a new project, you can do exactly that. There is no requirement to submit your entire accounts receivable or commit to a set volume each month.

This invoice-level flexibility matters for oilfield businesses because cash flow needs are rarely uniform. You may have some months where you can comfortably wait on payment and others where you need immediate working capital to cover fuel, crew wages, or equipment costs.

Being able to pick and choose which invoices to fund gives you a practical financial tool you can turn on and off based on actual business needs.

Does invoice factoring integrate with Enverus OpenInvoice?

Yes. FundThrough is directly partnered with Enverus, the oilfield industry's leading data and workflow platform, and integrates with OpenInvoice, Enverus's widely used invoice management system for oil and gas. This integration is a major advantage for oilfield service companies already submitting invoices through OpenInvoice.

Because your invoices are already in the Enverus system, connecting to FundThrough allows you to access funding with significantly less manual effort. You can sign up for FundThrough directly through the Enverus Workbench, sync your invoices automatically, and receive early payment without having to re-enter data or manage a separate workflow. For oilfield companies that bill large operators through OpenInvoice, this integration removes friction from the factoring process and speeds up the path from completed work to cash in hand.

What happens if an oil and gas customer pays a factored invoice late?

One of the core benefits of factoring with FundThrough is that once your invoice is funded, you have already been paid. The waiting is over for you. FundThrough takes on the responsibility of waiting for your customer to pay on their net terms, whether that is Net 30, Net 60, Net 90, or longer.

For oilfield businesses, this is especially valuable because large oil and gas operators are known to pay slowly, and sometimes even later than their stated terms. With FundThrough, late payment from your customer does not affect your cash position. You have already received your funds and can keep operations running, pay your crew, and take on new work without interruption. FundThrough's experience working with oilfield billing and the oil and gas payment cycle means they understand and are built to handle the realities of how major operators pay.

How do factoring companies determine which invoices and customers qualify?

Factoring approval is primarily based on the creditworthiness of your customer, not your own business credit or financial history. Since the factoring company is collecting payment from your customer on your behalf, what matters most is whether that customer is a reliable, creditworthy payer.

FundThrough uses AI-powered verification to assess your invoices and your customers quickly. The key factors evaluated include whether the invoice is for work that has been completed and accepted, whether the customer is a recognized and creditworthy business, and whether there are any liens, disputes, or encumbrances on the invoice. For oilfield companies, this typically means that invoices billed to major oil and gas operators with established payment track records are strong candidates for funding. Because FundThrough has deep experience in the oilfield sector, they understand the billing structures, master service agreements, and invoice formats common in oil and gas, which helps streamline the verification process.

Final Thoughts

Oilfield invoice factoring is one of the most effective tools available to oil and gas service companies dealing with slow payment cycles and high operational costs. Rather than waiting 60 to 120 days for invoices to clear, factoring puts that money to work immediately, allowing you to grow, hire, and take on new projects without interruption.

Of the five companies reviewed, FundThrough stands out as the best overall choice for most oilfield businesses. Its unlimited funding model, 100% advance rates, transparent fee structure, and deep integration with Enverus and QuickBooks make it the most capable and scalable option for oil and gas companies at any stage of growth. Whether you are a small oilfield contractor or a mid-size service company handling large multi-million-dollar contracts, FundThrough provides the financial flexibility and industry expertise to keep your business moving.

For businesses in the Southwest looking for a relationship-driven partner with decades of experience, Mazon Associates is a strong alternative. And for operators who need speed above all else, SB Factoring's same-day approval and funding process delivers.

The right factoring partner depends on your volume, contract size, technology needs, and how much transparency you expect in pricing.
