Vital Warning Signs
Customers rarely stop paying without warning. The pattern starts as a slower reply or a softer excuse, then hardens once a promise gets broken and nothing happens about it. Each tier below marks how much recovery leverage you have left.
Free to use, no account required.
Everything in this tier shows up before you ship. Plenty of solid customers look like this at the start, so treat these as inputs to the credit decision rather than verdicts on the customer. Terms are easy to set at onboarding and hard to claw back once an account is running, which is the whole reason the tier exists.
They can carry the terms as long as nothing goes wrong. The first slow month at their end arrives as a late invoice at yours. How much that costs is decided now, at the only point where changing the limit is still free.
The owner will not put their own name behind the company's debt. They know the company's finances better than any report will tell you. Declining to stand behind them is their own assessment of the risk, offered for free.
Too little payment history to know how they behave under pressure. A young company can fail between one order and the next, and receivables are usually where that shows up first. Shorter terms cost the relationship very little at this stage and give you something to watch.
The application is missing the fields that would tell you the most. A blank on the form costs one phone call today. The same gap costs weeks once an invoice is contested and nobody can point to what was agreed.
Routine paperwork already takes chasing. Filling in a form is the easiest thing a customer will ever be asked to do. How they handle the easy request is a fair preview of how they will handle an overdue balance.
Now the account has a history and the history has started to slip. A customer at this stage is usually still talking to you, and the conversation itself becomes part of the problem, since it feels like progress while the balance ages. Each deadline that passes without a consequence tells the customer how seriously you treat the invoice.
Their payment schedule has replaced the one on the invoice. Terms hold for as long as somebody enforces them. Once a customer has paid late and nothing happened, the number on the invoice becomes a suggestion, and every conversation after that starts from their schedule.
They admitted the balance, then stopped taking your calls. An acknowledged balance leaves them nothing to argue, so silence becomes the only tool they have left. It works for exactly as long as the exchange stays informal and undocumented.
A date came and went and nobody on their side mentioned it. The missed date matters less than the silence after it. A customer who lets a commitment pass without calling has learned what your deadlines cost them, which makes the next promise worth less than the first.
An objection with nothing specific in it to resolve. A dispute with nothing named in it cannot be closed, which is often why it was raised that way. Asking for the invoice number and the amount in writing either surfaces a real problem worth fixing or ends the objection.
Other suppliers are calling you for a reference, which usually means their existing credit is used up. Several suppliers asking about one account inside the same month is the market pricing a risk you already carry. That signal usually reaches you before anything shows up in your own aging.
They sent part of it and left the rest unaddressed. A payment that arrives with no date for the remainder buys goodwill and commits to nothing. Accept a few of them and the arrears stop looking like a problem to either side.
The behavior in this tier is a decision rather than an oversight. Someone has looked at your invoice, weighed it against everything else on the desk, and put it at the bottom. Internal collection effort tends to stop producing results here, because the customer has already learned what your follow-up costs them.
Cash up front has been offered and turned down. A customer who will not pay at delivery is telling you either that the cash is not there or that your invoice has stopped mattering to them. Both readings mean further shipments add to a loss rather than to a relationship.
Nobody has picked up or called back in weeks. Silence is cheap and it works, which is why it lasts. It stops working once the record moves to writing, because a certified letter creates a date that exists whether they answer or not.
A first broken promise can be a cash-timing problem, and treating it as one is reasonable. A second promise broken after the first was forgiven without consequence is different information. It tells you how the customer has decided to handle you specifically, and it usually means your account has been moved to the pile that gets paid when there is money left over. The useful move at this point is to stop negotiating by phone and require the next arrangement in writing with fixed dates and amounts, because a verbal arrangement is worth very little to whoever handles the account after you, and a written one survives being handed to an agency or to counsel.
A formal demand went out and the account looks exactly the same. A demand letter is the last step that costs you nothing to take. When it produces no response, every remaining option involves somebody outside the company, and the file you have built so far is what they will work from.
Certified mail is coming back refused, so someone is there and declining to sign. Refusing delivery takes more effort than ignoring a call, which makes it deliberate. Someone is weighing what a signature might later prove, and that is the behavior of a debtor who already expects a third party to be involved.
At this stage, recovery may depend on documentation, filing deadlines, and locating the business rather than persuasion alone. These conditions do not make an account unrecoverable, but they do narrow the available options. Most accounts reach this tier by drift rather than one event, which is why the earlier stages matter while an account still looks manageable.
The numbers on file no longer reach the business. A dead number leaves open whether the business closed or moved without notice, and that difference decides whether anything is recoverable. Public records answer it faster than another call attempt will.
Mail comes back with no forwarding address. An address that cannot be confirmed undoes most of what comes next, because a demand or a court filing depends on knowing where the business legally sits. Locating them becomes the work, and it comes ahead of any decision about the balance.
The account was built on something false before the first shipment. Misrepresentation at the outset changes what the account is. It becomes an evidence problem rather than a collection problem, where preserving the original documents matters more than any further contact with the customer.
A court has handed the company to a receiver, and payment now runs through them. Direct collection stops working the moment a receiver is appointed, and pressing on tends to work against the claim. What matters from here is being in the queue before the deadline closes.
The business has moved and the trail stops at the old address. A business that leaves without a forwarding address has usually left owing more than one supplier. Whether pursuit is worth the cost depends on what a search turns up, so the search comes before the decision.
The video starts muted so it does not startle anyone.
Watch the briefing
We uploaded this video more than 10 years ago. The warning signs it covers, and the need to act before an account deteriorates, still hold true today.
One sign on its own rarely decides anything. These run in tiers because the same behavior means something different depending on what came before it, which is the case laid out in building an accounts receivable early warning system and mapped to customer behavior in the three stages of a customer in trouble.

No single selection produces a critical rating. The assessment weighs severity, the number of signs, progression across tiers, and days past due so an isolated event is not treated like a pattern.
