It's Wednesday afternoon. You ring the depot to add two cases of milk to tomorrow's order and the voice on the other end goes careful. "I can't release that one, I'm afraid. The account's showing on stop."

So Thursday's drop isn't coming. Which means no milk, no bread order, and the fresh case that was going to carry Friday and Saturday is sitting in a warehouse thirty miles away. You are now standing in the kitchen working out which specials you can write on the board using only what's already in the fridge.

One quick disambiguation before we go on: this is about credit terms, the days your supplier gives you to pay. It is not about credit notes, which are the money your supplier owes you. Different thing, different post.

The bit nobody warns you about

Everyone talks about being on stop as a financial event. It isn't. It's an operational one, and the damage lands long before the money does.

A stop never arrives at a convenient moment. It surfaces mid-week, because that's when you next try to order, and the delivery it blocks is almost always the one carrying your weekend. You don't just lose the credit, you lose the drop. The van is loaded and routed by then, and "can I pay cash on delivery?" is a question most depots can't say yes to at short notice.

So you replace it yourself. A cash and carry run, or worse, a supermarket top-up at retail prices for things you normally buy wholesale. On a £900 order you might spend £1,100 covering the gap, before the three hours you or your head chef spend off the floor doing it. Then there's what you can't replace: the specials board shrinks, two cakes come off, and the customers who came in for the thing you're known for get told no.

Add it up honestly and a single stopped delivery in a busy week costs a few hundred pounds in premium buying, lost sales and time. Which is worth sitting with, because it's usually far more than the interest you thought you were saving by stretching the payment.

The team notices too. So does the driver. It's an awkward thing to explain twice.

Trade credit is a loan, so price it like one

Here's the reframe that changes how you treat this.

Say you buy £6,000 a month across your suppliers on standard 30-day terms, which is typical for foodservice wholesale. At any given moment, roughly a month's buying is sitting on their ledgers unpaid. That's £6,000 of somebody else's money permanently working inside your business, at zero percent.

Now price what it would cost to replace it. A business overdraft at a double-digit rate would run you several hundred pounds a year on that balance. A business credit card, considerably more. And the expensive quick money that operators reach for when cash gets tight is in a different league again.

Your suppliers, collectively, are your cheapest lender. They're also the only lender who delivers croissants.

That's not an argument for stretching them. It's the opposite. Cheap credit is worth protecting, and you protect it by being the account nobody in credit control has to think about. Stretching a supplier to fund a tight week isn't free money, it's borrowing against your own supply chain at an interest rate you only find out on a Wednesday afternoon.

Knowing which weeks are genuinely tight is a separate discipline, and a rolling 13-week cash flow forecast is how you get ahead of them rather than discovering them.

The settlement discount sum

At some point a supplier will offer you 2 to 5 percent off for paying by direct debit, or for settling within seven days instead of thirty. Most operators say no on instinct, because it feels like giving up breathing room. Do the sum on paper before you decide.

Take a 2.5% discount for paying on day 7 instead of day 30. You're giving up 23 days of float to earn 2.5%. There are roughly sixteen 23-day stretches in a year, so you're earning something in the region of 40% a year on the cash you handed over early. It's a rough number, not a compounded one, but the order of magnitude is the point: nothing else you can do with that money comes close.

Put it against your buying. On £6,000 a month, 2.5% is £150 a month, or £1,800 a year. Moving from 30-day to 7-day settlement means finding around £4,600 of working capital you were previously getting free. Even if you funded every penny of that on an overdraft, you'd pay a few hundred pounds a year to earn £1,800.

For most operators, taking it is right. With one condition, and it matters more than the arithmetic.

The practical middle path is the one most people miss: you don't have to choose once for everything. Put direct debit on your two biggest, most predictable lines, the ones where the discount is worth real money and the amount barely varies month to month. Keep invoice terms on everything else, where the amounts are lumpy and the float is worth more to you than a few pounds of discount.

How stops actually happen

Two things get you stopped, and only one of them is the one you're worried about.

The obvious one is lateness. Your invoices age past terms, the balance sits in the 30-plus or 60-plus column on their aged debtor report, and eventually the system flags it.

The quiet one is growth. Your credit limit was set when your account opened, based on a credit check and a guess at what you'd spend. Nobody has looked at it since. Two summers later you're buying half as much again, you're paying perfectly on time, and one busy week the running balance of unpaid invoices simply touches the ceiling. You get stopped for being a better customer than you used to be. Nobody rings to warn you, because from the system's point of view nothing is wrong.

It also helps to understand who's looking at you. Your account manager sees a customer they like, an account that's grown, someone who answers the phone. The ledger clerk in credit control sees a line on a report with a number and a days-overdue column, and they have never met you. The stop is applied by the second person, or increasingly by no person at all. That's why your rep often doesn't know about it until you tell them.

Then there's the pay-run mismatch, which catches out a lot of careful operators. You pay everyone on the 5th of the month. It's disciplined, it's consistent, and you think of yourself as a reliable payer. But if that supplier's terms ran out on the 28th, their ledger has quietly recorded you as eight days overdue, every month, for years. You've been building an ageing profile the whole time without ever feeling late.

Getting the account released

If it happens, the recovery path is fairly mechanical:

Ring credit control directly, not just your rep. The rep can advocate for you, but they usually can't lift a stop. Ask them to chase in parallel and go to the ledger yourself.
Ask precisely what releases it. Cleared funds, the full balance, or a proportion? Will a card payment release the account faster than a transfer that takes a day or two to land? It varies by supplier, and they'll tell you if you ask plainly.
Offer a part-payment plus a definite date, not a promise. "I'm paying £1,400 today and the balance on Friday the 8th" is something a clerk can put in the notes and defend to their manager. "I'll sort it this week" is not.
Then hit the date. Exactly. The one you gave, not a day after.

Expect the account to stay twitchy for a while afterwards. Some suppliers cut the limit, some move you to pro-forma for a period, and most want to see a couple of clean cycles before anything goes back to normal. Behave impeccably through that window and it fades. It does fade.

How to be the customer who never gets stopped

None of this needs a system. Three habits cover almost all of it.

Pay on a fixed day, and tell your suppliers which day it is. Predictable beats fast. If your pay-run day falls outside someone's terms, that's a specific, easy ask: extending to 45 days, or raising a limit that hasn't been reviewed in three years. Both are far simpler conversations than a full price negotiation, and reps say yes to them more often than you'd think.
Ring before you're late, not after. An operator who calls on the 26th to say the payment will be the 3rd is managing an account. An operator who calls on the 4th after being stopped is explaining one. Same money, completely different note on your file.
Keep one live fallback account per critical category. One alternative dairy, one alternative bakery or dry goods supplier, with a real order going through occasionally so the account stays open and the credit check stays current. An account you opened two years ago and never used is not a fallback, it's a phone number.

Trade credit is the cheapest borrowing you will ever get, and the only lender who turns up at 6am with your milk. Treat it like the loan it is, and the Wednesday phone call never comes.
