Contractor financing: which option fits which cash gap

Updated · LoanHelp editorial team · Educational, not financial advice

Contractors usually match financing to the cash gap, not the other way around. Equipment financing fits machines and vehicles; a line of credit or working capital often covers mobilization and payroll before the first draw; invoice factoring or receivables financing can help when GCs or owners pay on net-45, net-60, or hold retainage. This guide is educational only — LoanHelp is an independent referral service, not a lender or broker.

Common contractor cash gaps

Which tool fits which gap

Equipment financing secures the asset. Working capital and a line of credit often bridge payroll and mobilization. Invoice factoring focuses on approved receivables when customers pay slowly. Compare options in the table below, then run your own timing in our cash gap calculator.

Pay apps, change orders, and retainage

Many lenders and factors review approved pay applications, lien waivers, and the general contractor's payment history. Change orders can increase billings but may also delay approval. Retainage is often held until closeout — partners may advance on current billings but treat retainage differently. The Federal Reserve Small Business Credit Survey publishes research on how small firms use credit; we do not quote survey statistics here.

When stacking short-term advances gets risky

Products with daily or weekly remittance — including many merchant cash advances — can compress margin when stacked on one long job. Read remittance mechanics before you mix products on the same contract. LoanHelp does not offer MCAs; we explain them for comparison only.

Comparison: cash gap → option

Mobilization and materials up front

Usually fits: Working capital or a line of credit

Why: You pay subs and suppliers before the first pay application is approved or paid

Watch out: Match the term to the job — avoid long amortization for a short mobilization spike

Payroll before the first payment

Usually fits: Working capital or a line of credit

Why: Crew payroll is weekly; owner and GC payments often lag by weeks

Watch out: Stacking expensive daily-payment products on one long job can compress margin

Slow-paying GC (net-45–60 and similar)

Usually fits: Invoice factoring or receivables financing

Why: Turns approved invoices into cash while you wait on the general contractor

Watch out: Factors review your customer’s credit and invoice terms — not every GC file is alike

Retainage held until closeout

Usually fits: Plan separately — often not advanceable until released

Why: Retainage is intentionally held back; many products focus on current billings

Watch out: Do not assume retainage is factorable; model it in your cash-gap forecast

Equipment purchase or mid-job breakdown

Usually fits: Equipment financing or leasing

Why: The machine is collateral; terms differ from unsecured working capital

Watch out: Insurance, title, and uptime matter to the partner funding the asset

Seasonal slowdown

Usually fits: Line of credit or working capital

Why: Smooths overhead when billings dip between busy seasons

Watch out: Renewals and covenants vary — read what the partner proposes

Worked example (check the math)

Example only — not lending advice. You sign a $120,000 subcontract. Week 1 materials cost $18,000. Payroll is $11,000 per week for 4 weeks before the GC pays ($44,000 total). Cash out before the first customer payment: $18,000 + $44,000 = $62,000. You submit a first pay app at 20% complete ($24,000). Under net-30 or net-45 terms, that cash may arrive weeks later — model the gap in our cash gap calculator.

Equipment and tax timing

Iron and trucks often use equipment financing. Qualifying purchases may interact with Section 179 — see our Section 179 guide and IRS Publication 946 with your CPA. LoanHelp is not a tax adviser.

SBA programs (not LoanHelp)

SBA-guaranteed loans are made by participating lenders, not by LoanHelp. SBA loan programs and 7(a) loans (including certain revolving lines described by the SBA) may fit some contractors. Bonding support is described under the SBA surety bond program. We are not affiliated with the U.S. Small Business Administration.

FAQ

What financing do contractors use for a big job?
It depends on the cash gap. Equipment loans or leases fit machines and vehicles. Working capital or a line of credit often covers mobilization and payroll before the first draw. Invoice factoring can help when a GC pays on net-45 or net-60 terms. LoanHelp is a referral service — we do not approve or price financing.
How do pay applications and retainage affect financing?
Lenders and factors usually review approved billings, lien waivers, and the GC’s payment history. Retainage is often held until closeout, so many advance products focus on current billings rather than retainage still on the contract. Model both in a cash-gap forecast before you submit an inquiry.
Should contractors use a merchant cash advance on a long project?
Daily or weekly remittance products can be expensive when a job runs many months. They may fit very short bridges — but stacking advances on one long contract can squeeze margin. Read how remittance works on our merchant cash advance overview; it is education only, not an offer from LoanHelp.
Can SBA loans help contractors?
SBA-guaranteed loans are made by participating lenders, not by LoanHelp or the SBA directly. Programs described on SBA.gov include 7(a) loans (including certain revolving lines) and surety bond support for qualified contractors. We are not affiliated with the U.S. Small Business Administration.
Does equipment financing work for contractor trucks and iron?
Often yes — excavators, loaders, dump trucks, and trailers are common collateral classes. Section 179 may apply to qualifying purchases; see our Section 179 guide and IRS Publication 946 with your CPA. LoanHelp does not provide tax advice.
Does LoanHelp lend or broker contractor financing?
No. LoanHelp is an independent commercial financing referral service, not a lender or broker. We share one financing inquiry with one partner, who sets eligibility and terms.
