Invoice Factoring for Contractors
Invoice factoring lets contractors convert amounts owed by general contractors or owners into immediate cash. This guide explains how it works, when it fits, and how it differs from other financing.
Quick answer: Invoice factoring for contractors advances a portion (typically 70–90%) of amounts owed by GCs or owners. The factor buys your receivables and collects from the client. You get cash within days instead of waiting 30–90 days. Fees vary by factor and client credit.
What is invoice factoring for contractors?
Invoice factoring is a kind of receivables financing. A factor, which is a specialized lender, fronts you part of what general contractors or owners already owe you. You hand over an invoice or pay application, the factor sizes up the client’s credit, and you get roughly 70 to 90% of the invoice value within days. When the bill comes due, the factor collects from the client and sends you the rest, minus its fee. The whole point is to turn net-30 to net-90 terms into cash you can use now. For the wider category, see accounts receivable financing, and for a product comparison, see contractor invoice financing.
How contractor invoice factoring works
It runs in a few steps. You finish the work and bill the GC or owner. You send that same invoice to a factor. The factor checks the client’s credit, not just yours, then advances 70 to 90% to you within days. When the invoice is due, the client pays the factor directly, or you collect and remit, depending on how the deal is set up. Either way, the factor sends you the remaining balance once it’s paid, holding back its fee for fronting the money and carrying the credit risk. For background, see construction invoice payment delays. One nice thing: once your clients are approved, you can keep factoring new invoices as they come in, which smooths out cash flow over time.
When does invoice factoring make sense for contractors?
It fits a fairly specific picture. You’ve got clean invoices from GCs or owners who actually pay their bills. Your terms are long, net-60 or net-90, and waiting that long pinches. The fee works for your margin, which you’ll know only by comparing it against the cost of waiting or borrowing another way. Maybe you’re a sub billing a GC, or a GC billing an owner. Either way, the factor is judging whoever owes you. And if invoices keep coming, you can factor them again and again. For a one-time gap, contractor working capital might be simpler. For recurring ones, look at a contractor line of credit. If you’re stuck waiting, see contractor waiting on invoices.
Invoice factoring vs working capital vs line of credit
| Invoice factoring | Working capital | Line of credit | |
|---|---|---|---|
| Structure | Advance against specific invoices | One-time advance or short-term loan | Revolving; draw and repay as needed |
| Collateral | The receivables (invoices) | Often unsecured | Often unsecured |
| Best for | Converting GC/owner receivables to cash | Single payroll or material gap | Recurring gaps |
| Speed | Days (once client is approved) | Often fast | May require more setup |
Factoring is receivable-specific. You factor particular invoices, full stop. Working capital is general purpose money for payroll, materials, or whatever else. A line of credit revolves, so you draw when you need it and repay. Which one wins depends entirely on your situation. For the full lineup, see all funding options.
What factors look at: your client’s credit matters
The first question a factor asks is who owes you. That client’s creditworthiness, the GC or the owner, drives your advance rate and your fee more than anything else. Your relationship with them counts too, since the factor may confirm the work was done and the invoice is real. Clean invoices help, with clear amounts, due dates, and terms spelled out. A track record of completed work and paid invoices can tip things in your favor, and steady volume sometimes earns better terms. If a client’s payment is a coin flip, read contractor slow paying clients first.
Costs and fees for contractor invoice factoring
The main cost is the discount fee, usually 1 to 5% of the invoice per 30 days, set by the client’s credit and how fast they pay. On top of that, some factors add a flat or percentage factor fee. Advance rates run 70 to 90%, and stronger client credit can push the high end higher. Watch for minimum monthly volume requirements as well. Weigh the total against what waiting actually costs you. For a side-by-side, see contractor invoice factoring vs receivables.
There’s also the fine print. Some structures route payment straight to the factor; others let you collect and remit. One-time setup fees show up here and there, and certain factors lock you into a minimum commitment period. Read the agreement and ask about every fee before you sign anything. For more on payment delays, see contractor waiting on invoices.
One detail specific to construction: factoring often works on pay applications and progress billing, not just final invoices. The factor still underwrites the client and the contract behind it. If you’re a sub, subcontractor financing covers your situation, and contractor invoice factoring vs receivables compares factoring against the other receivables products.
Recourse vs non-recourse factoring
With recourse factoring, you’re on the hook if the client doesn’t pay. The factor can make you buy the invoice back or cover the shortfall. Non-recourse flips that. The factor eats the credit risk if an approved client stiffs them, and you pay more in fees for that protection. Know which one you’re signing up for. The broader accounts receivable financing guide has more.
Spot factoring vs full-service factoring: which fits contractors?
Spot factoring lets you factor one invoice at a time. You pick and choose, which suits contractors with occasional needs or anyone testing the waters. Full-service factoring, sometimes called whole-ledger, means you factor all or most of your receivables, with the factor advancing against new invoices as they’re generated. That’s the better fit when receivables are steady and the cash-flow need is ongoing. Minimum volume often applies to the full-service route. Compare both on fees and flexibility, and see contractor invoice factoring vs receivables for the full breakdown.
Real-world scenarios for contractor invoice factoring
Picture an electrical sub who finishes $100,000 of work for a GC on net-90 terms. Rather than wait three months, the sub factors the invoice, gets 80% ($80,000) within five days, and rolls it straight into payroll and materials on the next job. Now picture a general contractor who hits a $500,000 milestone for an owner paying net-60. The GC factors it, sees 85% ($425,000) inside a week, and funds mobilization on the next project. Or take a contractor juggling several jobs with payments landing at different times; they factor invoices as they’re created and keep cash flowing the whole way. Same pattern every time. Turn the receivable into cash before the terms run out.
Documentation and process: what factors need from contractors
Have your invoices or pay applications ready, showing the work done and the amount owed. A contract or purchase order proves the deal behind it. Some projects also call for lien waivers. The factor will verify the client, the GC or owner, and may reach out to them directly, so don’t be surprised by that. Be clear on whether your deal is recourse or non-recourse, since that’s who carries the credit risk. The whole thing usually moves faster than a bank loan, because the factor is underwriting the receivable and the client rather than digging through your entire financial history. For the bigger picture, see accounts receivable financing.
How to choose the right product
Start with a few honest questions. Do you actually have clean invoices from clients who pay? How does the factoring fee stack up against your other options? Will you need this once or over and over, because a line of credit may serve recurring needs just as well? Are you comfortable with recourse, or do you want the factor to carry the risk? And do you need spot factoring or whole-ledger? One more thing worth knowing: government receivables tend to appeal to factors because the payment is reliable, so see government contractor financing if that’s your world. Start with accounts receivable financing for the category and contractor invoice financing to compare products. When you’re ready, you can see what funding options may be available for your contracting business.
