How to Finance Construction Materials: Options for Contractors

Contractors often have to pay for lumber, steel, concrete, roofing, fixtures, mechanical components, and other materials before the corresponding customer or project payment arrives. Knowing how to finance construction materials means matching that cash-flow gap to a financing structure the job can realistically support.

Possible options can include supplier credit, a business line of credit, short-term working-capital financing, term financing, certain SBA-backed working-capital programs, and receivables financing after eligible work has been completed and billed.

The appropriate structure depends on the size of the material purchase, project timeline, supplier terms, customer payment schedule, existing obligations, and how much repayment pressure the contractor can absorb while the job is underway.

Start with the construction project’s cash cycle

Before comparing financing offers, map the cash cycle for the specific job.

Identify:

• the total material cost;
• required deposits;
• supplier payment terms;
• delivery dates;
• labor and subcontractor costs;
• anticipated inspections or approvals;
• progress-billing dates;
• retainage when applicable;
• expected customer payment dates;
• existing financing payments; and
• the amount of operating cash the business needs to preserve.

A profitable project can still create a serious cash-flow problem when materials must be purchased weeks before the corresponding draw, progress payment, or customer payment arrives.

The objective is to identify whether the business has a temporary timing gap or a broader working-capital shortage. That distinction can determine whether supplier terms, revolving credit, project-based financing, or another structure is more appropriate.

How to finance construction materials: options to consider

No single financing structure works for every contractor or project. Material financing should be evaluated based on the actual contract, expected collection schedule, project economics, and repayment source.

Supplier credit and trade terms

Supplier or trade credit may be one of the most direct ways to finance construction materials because it is tied to the purchase itself.

Depending on the supplier, account history, credit profile, and relationship, a contractor may be able to purchase materials and pay according to agreed invoice terms rather than paying the full amount at delivery.

Common trade arrangements may use Net-30, Net-45, Net-60, or other negotiated terms, although no specific payment period is universal.

Supplier credit can work particularly well when the expected project payment arrives before the supplier invoice becomes due.

Before relying on trade terms, confirm:

• the available credit limit;
• payment due date;
• whether deposits are required;
• late-payment provisions;
• whether early-payment discounts are available;
• whether the account can support the full material order; and
• what happens to future purchasing capacity if the customer pays late.

An important supplier relationship can be difficult to replace, so contractors should avoid using trade credit without a realistic plan to pay according to the agreed terms.

Business line of credit

A business line of credit generally provides revolving access to funds up to an approved limit. Contractors can draw capital for eligible expenses as needed and repay the balance according to the financing agreement.

This structure can fit recurring construction-material purchases because the business does not necessarily need to obtain a new lump-sum loan for every project.

For example, a contractor may draw from the line to place a material deposit and then repay the balance after receiving the corresponding progress payment.

Qualification and terms vary by provider. Underwriting may consider revenue, cash flow, business and personal credit, bank activity, operating history, existing obligations, industry, requested limit, and other factors.

Lines of credit may also involve interest or other financing charges, draw fees, annual or maintenance fees, renewal requirements, collateral, personal guarantees, or other provisions depending on the agreement.

A line of credit generally works best when the contractor has a clear repayment source and can restore availability as project payments are collected.

Short-term working-capital financing

Working-capital financing may help cover material deposits, payroll, subcontractor expenses, insurance, mobilization costs, or other short-duration project needs when cash is tied up elsewhere in the business.

Depending on the provider and program, underwriting may place substantial weight on recent business performance, bank activity, revenue, credit, operating history, existing obligations, and the intended use of funds.

Repayment structures can vary significantly. Some programs use monthly payments, while others may require weekly, daily, or another payment schedule.

That distinction is especially important in construction. A financing structure requiring frequent payments may create cash-flow pressure when the contractor receives customer payments only after monthly draws, inspections, milestones, or invoice approval.

Compare the repayment calendar with the project’s collection calendar before accepting financing.

For additional structures, see our guide to short-term business financing options.

Term financing for larger material purchases

Term financing generally provides a defined amount of capital that is repaid according to an agreed schedule.

It may be worth considering when the material purchase is substantial and connected to a larger project, expansion, or ongoing operating plan rather than a brief timing gap.

A contractor should avoid choosing a long repayment period solely because it produces a lower scheduled payment. The financing term should make sense relative to how quickly the materials and project are expected to generate cash flow.

If a material purchase will be converted into customer payment within a relatively short period, carrying the obligation for years may not be economically necessary.

Conversely, a larger expansion involving multiple jobs, inventory, or long-term business growth may justify evaluating a longer repayment structure.

SBA 7(a) Working Capital Pilot

Qualified construction businesses may also want to evaluate the SBA 7(a) Working Capital Pilot, or WCP, through a participating lender.

The WCP is a monitored line-of-credit program within SBA’s 7(a) program. Current SBA guidance identifies businesses fulfilling larger contracts or projects, or borrowing against accounts receivable or inventory, among the businesses that may benefit from the program.

The program can be structured around transaction-based or asset-based working-capital needs, depending on the borrower and transaction.

For contractors and homebuilders, that can make the program relevant to certain project costs, including materials, labor, and subcontractor expenses when the business and project qualify.

The WCP is not automatic financing for every construction company. SBA eligibility requirements, lender underwriting, operating history, financial reporting, project details, repayment ability, and other program requirements apply.

Current information is available from the U.S. Small Business Administration’s 7(a) Working Capital Pilot guidance.

SBA CAPLines for qualifying contract or construction needs

SBA CAPLines are another group of working-capital programs that may be relevant in certain construction situations.

Contract CAPLine is designed to finance costs associated with one or more specific contracts, including eligible overhead or general and administrative expenses allocable to those contracts.

Builders CAPLine is more specialized. Current SBA guidance describes it as financing for qualifying small general contractors constructing or rehabilitating residential or commercial property for resale.

That distinction matters. Builders CAPLine should not be treated as a universal material-financing program for every contractor or subcontractor.

The appropriate SBA structure depends on the business, project, contract, use of proceeds, eligibility, lender underwriting, and current program requirements.

Current CAPLines information is available through the SBA’s lender and loan-program resources.

Invoice factoring

Invoice factoring may become relevant after eligible work has been completed and billed to a commercial customer.

Under a factoring arrangement, a business generally sells eligible accounts receivable to a factoring company in exchange for an advance, subject to the agreement.

This can help replenish cash that was previously used for materials, labor, or other project expenses while the contractor waits for an eligible customer invoice to be paid.

However, construction receivables can be more complicated than ordinary commercial invoices.

Eligibility may depend on factors such as:

• whether the work has been completed or approved;
• whether the invoice is undisputed;
• the credit quality of the customer;
• retainage;
• lien rights;
• contract terms;
• pay-when-paid or similar provisions when applicable;
• customer concentration;
• existing liens or assignments; and
• the factoring provider’s underwriting requirements.

Factoring therefore should not be assumed to provide cash against every progress billing, retainage amount, disputed invoice, or unapproved change order.

Accounts receivable financing

Accounts receivable financing may also provide liquidity based on eligible commercial receivables, but it is not necessarily structured the same way as factoring.

Depending on the arrangement, the contractor may retain ownership of the receivable while using eligible accounts receivable to support a financing facility.

If billed work is creating the cash-flow gap, compare accounts receivable financing vs. invoice factoring before choosing a structure.

Purchase-order financing

Purchase-order financing can be relevant in some transactions, but contractors should be careful not to assume it fits every construction project.

Traditional purchase-order financing is generally more closely associated with transactions in which a business has a verifiable customer order and a supplier that will provide finished goods needed to fulfill that order.

It may be less suitable when the contractor’s obligation involves substantial labor, installation, progress billing, change orders, retainage, performance risk, or other construction-specific requirements.

A contractor supplying materials or products under a straightforward customer order may have a different financing profile from a general contractor performing a complex construction contract.

The provider will typically evaluate the purchase order, supplier, customer, margins, transaction structure, and fulfillment process before determining whether the transaction is eligible.

Match financing to the project’s payment schedule

Construction businesses can generate strong revenue and still experience cash-flow pressure because expenses and customer payments occur at different times.

Before financing materials, compare the proposed payment schedule with the project’s expected cash inflows.

Consider:

• when suppliers must be paid;
• when materials will be delivered;
• when labor and subcontractors must be paid;
• when the contractor can submit a draw or invoice;
• how long approval normally takes;
• whether inspections or certifications are required;
• whether retainage applies;
• how quickly the customer typically pays; and
• what happens if the project is delayed.

A financing payment that looks manageable in total can still create problems if it comes due before the corresponding project cash is collected.

Account for retainage and progress billing

Retainage can materially affect construction cash flow because a portion of payment may remain outstanding until later in the project or after completion.

Similarly, progress billing can create delays between completing work, submitting documentation, obtaining approval, and actually receiving funds.

Do not build a material-financing plan on the assumption that every invoice will be collected immediately.

Estimate how much cash will remain unavailable because of retainage, pending approvals, disputed change orders, punch-list work, or normal collection timing.

The business should maintain enough liquidity to continue operating while those amounts remain outstanding.

What financing providers may review

Providers may evaluate both the construction business and, in some cases, the underlying project or receivable.

Depending on the financing structure, underwriting may consider:

• business revenue;
• cash flow;
• business bank activity;
• time in business;
• business and owner credit;
• existing debt and financing obligations;
• industry and trade specialty;
• project history;
• customer concentration;
• signed contracts;
• purchase orders;
• supplier quotes;
• accounts receivable aging;
• project margins;
• collateral when applicable; and
• the requested amount and intended use of funds.

There is no universal credit score, revenue threshold, time-in-business requirement, or contract size that applies to every construction-material financing program.

Requirements vary by provider and financing structure.

Prepare the project documentation before applying

Organized documentation can reduce avoidable back-and-forth and make it easier for a provider to understand the request.

Depending on the program, useful documents may include:

• recent business bank statements;
• profit-and-loss statements;
• balance sheets;
• business tax returns when requested;
• accounts receivable and accounts payable aging reports;
• a signed construction contract;
• purchase orders;
• supplier quotes;
• materials lists;
• project budgets;
• draw schedules;
• customer invoices;
• existing debt information;
• insurance documentation when relevant; and
• a clear explanation of how the financing will be repaid.

Not every provider requires every document on this list.

See our guide to documents that may help speed up a business financing review for additional preparation guidance.

Compare the complete cost of financing

Do not choose material financing solely because it provides the largest approval or the fastest decision.

Review the complete financing structure, including:

• amount actually available;
• cash contribution required;
• interest or financing charges;
• origination or other fees;
• payment amount;
• payment frequency;
• repayment period;
• estimated total repayment;
• collateral requirements;
• personal guarantees;
• prepayment provisions;
• renewal requirements when applicable;
• late or default provisions; and
• the effect of the payment on normal operating cash flow.

The relevant question is not simply whether the business can obtain the money. It is whether the project economics can support the financing after materials, labor, overhead, retainage, and other costs are considered.

Build a contingency for construction delays

Construction schedules can change even when the underlying project is sound.

Potential delays may result from:

• weather;
• inspections;
• permitting;
• material shortages;
• supplier delays;
• change orders;
• customer approvals;
• subcontractor availability;
• site conditions; or
• other project disruptions.

A contractor should therefore evaluate whether it could continue making the financing payment if the expected customer payment arrives later than projected.

If the financing works only when every project milestone occurs on the most optimistic schedule, the business may have too little room for normal construction risk.

When financing construction materials may not solve the problem

Financing can help bridge a temporary project cash-flow gap, but it does not make an unprofitable job profitable.

Be cautious about adding financing when:

• the project margin is already too thin to support financing cost;
• the customer has unresolved payment problems;
• the contract terms are unclear;
• major change orders remain disputed;
• the business is repeatedly using new financing to make payments on existing financing;
• there is no clear repayment source;
• existing obligations already consume too much operating cash; or
• the project would remain cash-flow negative even if the materials were financed.

In those situations, the contractor may need to revisit project pricing, supplier terms, billing practices, collections, contract terms, or the scope of the work before adding another financing obligation.

How Bright Side Capital approaches construction-material financing

Bright Side Capital uses a multi-program approach to help contractors and other business owners explore and compare commercial financing programs from multiple providers.

For a construction-material request, the review may consider business revenue, cash flow, bank activity, operating history, credit profile, existing obligations, the material purchase, supplier information, project documentation, expected customer payments, and the repayment structure the business can realistically support.

Not every contractor, project, invoice, purchase order, or material expense qualifies for every financing program. Approval, amounts, pricing, collateral, guarantees, documentation, and timelines vary by provider and program.

Frequently Asked Questions

Can construction materials be financed?

Potentially. Contractors may be able to finance eligible material purchases through supplier credit, a business line of credit, working-capital financing, term financing, certain SBA-backed programs, or other commercial financing structures. Availability depends on the business, project, provider, and transaction.

What is the best way to finance materials for a construction project?

There is no single best option for every project. Supplier terms may work when customer payment arrives before the vendor invoice is due. A line of credit may fit recurring purchases, while project-based or working-capital financing may be considered for larger timing gaps. The financing structure should match the project’s collection schedule and repayment capacity.

Can a contractor use a business line of credit for materials?

Potentially. A business line of credit may be used for eligible material purchases when the provider permits the use and the contractor qualifies. Limits, pricing, repayment requirements, collateral, and guarantees vary by provider.

Can unpaid construction invoices be factored?

Some eligible commercial construction receivables may qualify for factoring, but not every progress billing, retainage amount, disputed invoice, or change order is factorable. Eligibility depends on the invoice, customer, contract, provider, and transaction.

Can purchase-order financing pay for construction materials?

Possibly, but traditional purchase-order financing is generally better suited to straightforward transactions involving customer orders and suppliers of goods. Complex construction projects involving substantial labor, installation, progress billing, or retainage may not fit a traditional purchase-order financing structure.

Does SBA offer working-capital financing for contractors?

Qualified construction businesses may have access to SBA-backed working-capital programs through participating lenders. Current options can include the 7(a) Working Capital Pilot and certain CAPLines structures, depending on the business, contract, project, and applicable program requirements.

Can materials be financed before the contractor invoices the customer?

Potentially. Supplier credit, lines of credit, working-capital programs, and certain project-based financing structures may provide capital before a customer invoice exists. Invoice factoring, by contrast, generally requires an eligible receivable that has already been created.

What documents may be needed to finance construction materials?

Requirements vary. Providers may request bank statements, financial statements, a signed contract, supplier quote, materials list, purchase order, draw schedule, accounts receivable information, existing debt information, and other documentation relevant to the business or project.

Does a signed construction contract guarantee financing?

No. A signed contract can help document the project and expected repayment source, but providers may also review the contractor’s financial profile, customer, margins, existing obligations, credit, bank activity, collateral, and other underwriting factors.

Should a contractor borrow the maximum amount available for materials?

Not necessarily. The financing amount should be tied to the actual project need and the business’s ability to support repayment. Borrowing more than necessary can increase financing cost and payment pressure without improving the project outcome.

Finance the material purchase around the project’s cash flow

The best way to finance construction materials is to begin with the project rather than the financing offer.

Determine when materials must be purchased, when customer payments are expected, how much retainage or approval delay may occur, and what payment schedule the business can realistically support.

Then compare supplier terms, revolving credit, project-based programs, receivables financing, and other commercial financing structures based on both cost and timing.

The objective is to keep the job moving without creating a financing obligation that puts the rest of the construction business under unnecessary pressure.
