Contract Line of Credit vs. Payroll Funding: Which Fits Your Award?
Both solve cash flow. They solve different cash flow. Here is how to tell which structure your contract actually needs.
Contractors often ask for “a line of credit” when what they actually need is payroll funding, or ask for payroll help when a revolving facility would serve them better across the full period of performance. The two structures overlap enough to be confused and differ enough that the wrong one leaves you short.
The short answer
A contract line of credit is general-purpose working capital sized to your award. Payroll funding is purpose-built capital sized to your labor cost and timed to your pay cycle.
If your costs are mixed across materials, subs, equipment, and labor, the line of credit is the better instrument. If your cost structure is overwhelmingly people, and the constraint is making payroll on a fixed date, payroll funding is built for exactly that.
Contract line of credit
A revolving facility tied to an awarded contract. You draw against it as expenses come due and repay as the agency pays your invoices. Because it revolves, it covers you repeatedly across the life of the contract rather than funding a single event.
- Flexible use. Materials, subcontractor payments, equipment, overhead, and labor all qualify.
- Sized to the award. The limit is set against the contracts you hold, not your historical revenue, and what you can draw tracks the revenue you have earned, billed or not.
- Reusable. Draw and repay across multiple billing cycles without re-underwriting.
- Bank-compatible. Can often be structured alongside an existing bank line through an intercreditor agreement.
Payroll funding
A facility structured around your payroll calendar that advances against earned-but-unbilled revenue, meaning work your people have already performed but that you have not yet invoiced. That distinction is the whole point: you are not waiting on the invoice cycle to pay the people doing the work.
- Matched to your cycle. Weekly, bi-weekly, or bi-monthly, structured to your actual schedule.
- Draws on unbilled work. Capital available against hours already worked, before invoicing.
- Scales with headcount. The facility grows as you staff up for a larger or multi-site award.
- Bid with confidence. Take on larger labor-heavy awards knowing payroll is covered.
Side by side
The two structures are easiest to separate by asking what each one is measured against, because that is what decides whether it can cover the cost you are actually worried about.
| Contract line of credit | Payroll funding | |
|---|---|---|
| What sets the limit | The contracts and awards you hold | Your labor cost on the award |
| What you can draw against | Revenue you have earned, billed or not | Hours already worked, before invoicing |
| What the money covers | Any cost of performing: materials, subcontractors, equipment, overhead, labor | Labor cost, on your pay dates |
| When you draw | As costs come due, across the life of the contract | On your pay cycle, weekly, bi-weekly or bi-monthly |
| How it clears | Repay as the agency pays, then draw again | Clears as the related invoices are paid |
| What makes it grow | Contracts won and performed | Headcount on the award |
| Re-underwriting per draw | None once the facility is live | None once the facility is live |
| Best fit | Costs spread across materials, subs, equipment and labor | Costs that are overwhelmingly people |
Two rows are worth dwelling on. Both facilities can reach work you have performed but not yet billed, so neither one makes you wait on the invoice cycle. The difference is what the limit is measured against: a line of credit is sized to the contracts you hold, so it grows as you win and perform more work, while payroll funding is sized to the labor on the award, so it grows as you staff up.
When you need both
These are not mutually exclusive, and plenty of contractors run both. A common pattern on a large services award: the line of credit handles mobilization, equipment, and subcontractors, while payroll funding carries the labor cost through each pay cycle.
The right question is not which product is better. It is where your cash actually runs out, and on what schedule. Answer that honestly and the structure picks itself.
Common questions
What is the difference between a contract line of credit and payroll funding? A contract line of credit is a revolving facility sized to your award, drawn and repaid as costs and collections move through the contract. Payroll funding is sized to a pay cycle and timed to it, advancing against hours already worked but not yet invoiced. The line covers the whole cost of performing; payroll funding covers labor on a fixed schedule.
Can I use both at the same time? Yes, and on a large services award it is common. A typical split has the line of credit carrying mobilization, equipment and subcontractors, while payroll funding covers the labor cost through each pay cycle.
Which one do I need if my contract is labor-heavy? Payroll funding maps most naturally to a labor-heavy award, because the outflow arrives on a fixed schedule and the facility is built around that schedule. If the award also carries material, equipment or subcontractor costs, a line of credit alongside it covers what payroll funding is not sized for.
Does payroll funding require me to have invoiced first? No. It advances against hours already worked, which is what makes it fit the gap between performing the labor and billing for it.
How do I know which one my contract actually needs? Map when cash leaves against when it comes back in. If the shortfall lands on payroll dates, that is payroll funding. If it is spread across mobilization, materials and subs, that is a line of credit. Describe the award and we will tell you which pattern it fits.
