Every business carries a debt it will not collect. The amount is decided less by the pursuit than by the paperwork in place beforehand and by how long the creditor waited before treating silence as an answer.
Hope is the expensive part
The common pattern is not aggressive non-payment. It is a customer who apologises, promises a date, misses it, apologises again, and continues ordering. Each cycle feels like progress and the balance grows.
Set a rule and apply it without discussion: at a defined number of days overdue, supply stops. Not as a threat during a call, but automatically, because the rule exists. Companies that do this collect more and lose fewer customers than those that negotiate each time, because the rule is impersonal and everyone learns it is real.
What you should have before the dispute
Recovery is mostly evidence. Before you need it, you should hold a signed contract or accepted order, proof of delivery that the customer acknowledged, correctly issued invoices, and a written record of any variation agreed along the way.
The gap that causes most difficulty is delivery. A customer disputing a debt will frequently dispute receipt or condition, and a signature on a delivery note settles in a minute what months of correspondence cannot.
Agree late payment interest in the contract too. It is rarely the reason anyone pays, but it changes the arithmetic of delay and gives you something to waive in a settlement.
Escalate in a defined sequence
A statement of account, then a formal written demand stating the amount, the basis and a deadline, then a lawyer’s letter, then proceedings. Each step on a fixed timetable rather than when someone remembers.
The formal demand does more than people expect. It converts an administrative chase into a documented position, and it is often the point at which a customer who has been prioritising other creditors moves you up the list.
Decide what the debt is worth pursuing
Litigation has a cost and a duration, and enforcement against a debtor with no assets returns nothing however sound the judgment.
Before proceeding, establish whether the customer is still trading, whether they are paying others, and whether anything exists to enforce against. A settlement at sixty per cent from a solvent customer is usually a better outcome than a full judgment against an empty one.
Where the balance is small and the debtor is weak, writing it off deliberately and stopping supply is a decision, not a defeat. The mistake is drifting into that outcome after two years of cost.
