Invoice factoring vs. line of credit: which is better for a roofing business?

Neither is universally "better" for a roofing business — they solve different problems. Choose invoice factoring when slow-paying commercial customers on net-30 or net-60 terms are your cash-flow bottleneck and you want cash advanced against those receivables fast, even with weaker personal credit. Choose a business line of credit when you want flexible, reusable funds for any expense (payroll, fuel, materials, weather gaps) and you can qualify on your own credit and revenue.

Factoring is the sale of your unpaid invoices to a factor for upfront cash; it isn't a loan. A line of credit is revolving debt — you draw what you need, repay, and draw again, paying interest only on the amount you borrow. That core difference drives every trade-off below.

How invoice factoring works for roofers

You sell outstanding invoices to a factoring company, which typically advances 80% to 90% of the invoice value upfront, then collects payment directly from your customer. When the invoice is paid, the factor releases the reserve minus a factoring fee that usually runs 1% to 5% of the invoice value. Crucially, approval leans on your customers' creditworthiness, not yours — as one industry explainer puts it, "it's their clients' creditworthiness that matters", so a roofer with thin or bruised personal credit can still qualify if they bill creditworthy commercial accounts. The factor also takes over collecting on those invoices, which means your customers interact with them directly. See our walkthrough of how roofing invoice factoring works for the mechanics.

How a line of credit works

A business line of credit is revolving credit you draw from up to a set limit, repaying and re-drawing as needed. It's not tied to specific invoices, so you can spend it on anything — crew payroll during a rain delay, a deposit on shingles, an emergency truck repair. The SBA's CAPLines program even offers an asset-based revolving line of credit built for "cyclical growth, recurring and/or short-term needs", which fits roofing's seasonal swings well. The catch: qualifying generally depends on your business's credit and revenue, so it's harder to land with poor personal credit than factoring is.

When each wins

• Factoring wins when you do B2B commercial roofing, carry large unpaid invoices on net-30/60 terms, need cash in a day or two, and your own credit is weak — but your customers pay reliably.
• A line of credit wins when you want one flexible pool for unpredictable costs, you bill some cash/residential jobs (which can't be factored well), you care about your customers not knowing you use financing, and you can qualify on your own books.

Many roofers use both: a line of credit for everyday working capital and factoring to unlock cash from a single oversized commercial draw. Compare structures further in our commercial lines of credit overview.
