Invoice discounting lets a supplier get paid now for invoices their customer will pay later. You raise an invoice on completed work or delivered goods, a financier advances you most of its value immediately, your customer pays the invoice on their normal terms, and the advance is settled from that payment. You keep control of your customer relationship, and you convert a receivable sitting on your books into cash you can deploy on the next order. For solar suppliers whose customers pay on 30, 60 or 90-day terms, it is the direct answer to being profitable on paper but short of cash in practice.
”- Invoice discounting advances you most of an invoice's value now, instead of waiting for the payment term.
- It applies to invoices already raised, work delivered, not to future orders.
- Your customer pays on their normal terms, and the advance is settled from that payment.
- It converts receivables into working capital you can deploy on the next order.
- It is the answer to being profitable on paper but cash-poor in practice.
The problem it solves
A supplier delivers goods, raises an invoice, and then waits. Thirty days. Sixty. Sometimes ninety. Meanwhile they have already paid for materials, labour and logistics, and the next order needs funding now.
This is the structural squeeze in B2B supply: you can be entirely profitable and still run out of cash, because the profit is sitting in an invoice, not in your account. It is the supplier-side mirror of the problem that makes solar EPCs run out of working capital.
Invoice discounting exists precisely to close that gap, it turns the invoice into cash now.
How it works, step by step
- You deliver and invoice. Goods are shipped or work is completed, and you raise an invoice on your customer with their normal payment terms.
- You submit the invoice for discounting. The financier assesses it, primarily on the strength of the invoice and the customer's credit, not solely your balance sheet.
- You receive an advance. Most of the invoice value is paid to you immediately, rather than in 30, 60 or 90 days.
- Your customer pays on their normal terms. Their experience does not change.
- The advance is settled from that payment, with the financing cost deducted.
The net effect: the cash that was locked in a receivable is now available to fund your next order, instead of sitting idle on your books for a quarter.
What it costs, and when it is worth it
Invoice discounting carries a financing cost, deducted when the invoice settles. The right way to judge it is not "is it free" (it is not) but "what does the cash unlock".
If waiting 90 days for payment means you cannot take the next order, the cost of discounting is trivially small against the margin on the order you would otherwise turn down. If the cash would simply sit idle, discounting is an unnecessary expense. The test is opportunity cost, not the fee in isolation.
| Use invoice discounting when | Do not bother when |
|---|---|
| Cash locked in receivables is blocking your next order | You have ample cash and no pending opportunity |
| Customer terms are long (60-90 days) | Customers pay quickly anyway |
| You are growing faster than your cash cycle allows | Growth is not constrained by cash |
| You want to avoid diluting equity to fund working capital | The cost outweighs the opportunity it unlocks |
How it differs from PO Finance and factoring
These get confused constantly, and the difference is about timing and control:
- Invoice discounting is after you deliver and invoice. It releases cash from an existing receivable, and you typically retain control of collections and the customer relationship.
- PO Finance is before you deliver. It funds the purchase of materials against a confirmed order, so you can fulfil an order you could not otherwise afford. See PO Finance.
- Factoring also advances against invoices, but typically involves the financier taking over collections, which changes your customer's experience.
Many suppliers use both discounting and PO Finance: PO Finance to fund the materials for an order, invoice discounting to release the cash once it is delivered and invoiced. For a full side-by-side, see PO Finance vs invoice discounting vs vendor payment.
Why it matters for solar suppliers
Solar supply has long cycles and large ticket sizes, exactly the conditions that strand cash in receivables. A supplier delivering modules or balance-of-system components to an EPC often waits through the EPC's own milestone cycle before being paid.
Invoice discounting breaks that dependency. It lets you sell to buyers with long payment terms without letting their terms dictate your growth, you can take the next order rather than waiting on the last one.
On VyaparCred, suppliers reach verified demand and can attach invoice discounting to the receivables they generate, so selling and getting paid are part of one flow rather than two separate problems. If you supply solar components, see selling on VyaparCred.
Sell, then get paid, without the wait
VyaparCred connects suppliers to verified demand and lets them attach invoice discounting to the receivables they raise, so long customer terms stop dictating your growth.
Reach verified buyers actively sourcing the components you supply.
Attach invoice discounting to release cash from receivables rather than waiting 60-90 days.
Keep your customer relationship, their payment experience does not change.
