Definition
A letter in which a customer confirms the amount owed and agrees to pay the funder.
Why it matters
Often requested for large or concentrated invoices.
Where it shows up in a deal
A funder asks for an estoppel letter when a single invoice or a single buyer is large enough that a surprise would matter. Your customer's controller or AP manager signs it, confirming the balance, that the goods or services were accepted, that no offsets or disputes exist, and that payment will go to the funder.
What it affects
- It closes off defenses the customer knew about on the date it was signed.
- It can unlock a higher advance or a raised concentration cap on a key account.
- Obtaining one takes days to weeks, so it belongs in the timeline before a funding date is promised.
- A customer refusing to sign is itself information worth having before you ship more.
