When a key supplier puts your client on stop-credit

The signal

When a supplier moves a client from terms to cash-on-delivery, or pulls their credit account altogether, that is not an internal metric — it is an outside party putting money on its judgement that the client is a risk. Suppliers do this reluctantly, because it costs them sales, so when they act it usually reflects a real and recent deterioration. You may hear about it from the client, or notice it when a normal trade account suddenly demands payment up front.

It is a late-ish warning, but a sharp one, precisely because it comes from someone with skin in the game.

What it means

Stop-credit removes the cheapest financing the business had. Where the client could previously take 30 days of free supplier credit, they must now pay immediately — which pulls forward a chunk of cash demand exactly when cash is already tight. The constraint is also self-reinforcing: paying suppliers up front drains cash, which makes other payments slower, which can prompt yet more suppliers to tighten terms.

It often signals that the client's strain is now visible externally, which means it has been building for a while. The constructive read is that the strain frequently traces back to the client's own debtors — their cash is stuck downstream, so they cannot pay upstream. That makes recovery a direct lever on the problem.

Run the play (steps)

1. Treat any supplier credit withdrawal as a significant external signal, not a minor administrative change.
2. Identify which critical suppliers are involved and whether others are likely to follow.
3. Model the cash impact of paying those suppliers up front instead of on terms.
4. Trace the client's own strain back to overdue receivables, the usual upstream cause.
5. Prioritise freeing that trapped cash so the client can rebuild supplier confidence.

What to say to the client

Be candid about what it means: "A supplier putting you on cash-up-front is the market telling you it sees strain. Let's get ahead of it — and a lot of your stuck cash is probably sitting in your own overdue invoices."

Recovering those invoices is the most direct way to restore the cash that lets the client return to terms. Point them to refer a debt so the upstream blockage starts clearing quickly.

When to bring in Merion

Escalate promptly when stop-credit signals real strain and the client's own debtor book is part of the cause. Recovering trapped receivables relieves the immediate cash demand and helps the client rebuild supplier trust. This is general professional information, not advice for a specific situation.
