Invoice factoring lets a solar contractor sell an unpaid invoice to a financier at a discount and receive most of the value immediately, with the balance released when the customer pays. Because the financier is relying on your customer's credit rather than your balance sheet, it is accessible to contractors who cannot get a bank line, and it scales with revenue instead of being fixed at approval. It solves a timing problem between completing work and being paid, and it does nothing for a job that was priced too low in the first place.
”- The financier is underwriting your customer, not you. That is why it is accessible.
- It scales with revenue, unlike a line fixed at the moment you least needed it.
- Factoring usually moves collections to the financier. Discounting usually does not.
- Price it against the cost of not having the cash, not against a bank rate.
- It fixes timing, never margin. A loss funded earlier is still a loss.
The squeeze factoring is built for
A solar contractor pays for equipment, subcontractors and crew during the job. The invoice goes out at completion or at a milestone, and payment arrives weeks later, often longer once retainage and approval cycles are counted. Meanwhile the next job has already started and needs the same money again.
This is why growth feels like drowning in contracting. Every additional project widens the gap between money out and money in, and the business consumes cash exactly when it is winning work. The pattern is described in why solar EPCs run out of working capital mid project.
Factoring attacks the gap directly. Instead of waiting out your customer's payment cycle, you convert the invoice into cash now and pay for the speed.
How it works, step by step
- You complete the work and invoice the customer as normal.
- The financier verifies that the work was delivered and the invoice is undisputed. This step is why clean documentation matters.
- You receive an advance, typically the large majority of the invoice value, within a short window.
- The customer pays on their normal terms, to the financier under a factoring arrangement.
- You receive the balance, less the fee.
Two variables define the deal. The advance rate determines how much cash you get now. The recourse position determines who absorbs the loss if the customer never pays: with recourse, you do, and pricing is lower; without recourse, the financier does, and pricing is higher.
The related product, where you keep collections and the arrangement stays between you and the financier, is invoice discounting. The practical differences are in factoring against invoice discounting.
What drives the cost
| Factor | Effect on price |
|---|---|
| Customer credit quality | The main driver, because they are the source of repayment |
| Days outstanding | Cost accrues while the money is out, so slow paying customers cost more |
| Recourse or non recourse | Non recourse transfers default risk to the financier and prices higher |
| Volume and consistency | A regular programme prices better than occasional one off invoices |
| Documentation quality | Clean proof of delivery and acceptance reduces dispute risk, which is priced in |
| Disputes and retainage | Contested amounts and held back retainage are hard to fund at any price |
Compare offers on the all in cost for one typical invoice over its real payment period, including every fee outside the headline rate. Two quotes expressed on different bases are not comparable until you do that arithmetic.
Factoring against the alternatives
Against a bank line of credit, factoring is easier to obtain without collateral and grows with revenue, while a line is usually cheaper per dollar and more flexible in use. Contractors who can get a line and keep it sized to the business often should.
Against equipment financing, they solve different problems. Equipment finance covers what you buy. Factoring covers the gap after you have installed it and billed for it.
Against pre-shipment funding, the difference is which end of the job is squeezed. If the pressure is buying panels before the project draws, that is pre-shipment financing, not a receivable product. Many contractors use both across one project, which is the cycle described in managing cash flow in a solar EPC business.
When factoring is the wrong answer
When the job is unprofitable. Factoring accelerates cash, it does not create margin. Funding a loss earlier just reaches the loss sooner, and the fee makes it slightly worse. If jobs are not covering cost, the fix is in the financial metrics that matter for a solar EPC.
When the invoice is disputed. Contested work is not fundable. Resolve the dispute first, because no financier advances against an amount that might not exist.
When the customer relationship cannot take it. Under a factoring arrangement your customer typically pays the financier, which they will notice. For most commercial customers this is routine, but it is worth thinking about before the first invoice is assigned.
When you are actually underpricing the work. Chronic cash shortage is sometimes a pricing problem wearing a finance costume, and no facility fixes that.
