Why Are Older Debts Harder to Collect? The Decay Curve
Older debts are harder to collect because an invoice does not lose value steadily — it falls off a curve. A commercial account is collectable at roughly 90 percent or more while it is under 30 days past due, around half that past 90 days, and below 20 percent once it crosses 180. The money owed never changes. What changes is everything that makes the money reachable: the debtor’s solvency, the freshness of the trail to them, the strength of your evidence, and — across borders — the legal right to enforce at all.
Age does not dilute the debt. It dismantles the means of collecting it.
You are likely asking because an account has aged further than you intended, and you want to know whether the window has closed. That is the right question, and it has a precise answer rather than a reassuring one. Below: how much collectability a debt loses at each stage, why a cross-border debt decays on a second and harsher clock, and the figure that reframes the entire cost of waiting.
What is the recovery rate for fresh debt versus aged debt?
Recovery rates fall as the account ages, and the fall accelerates.
The curve, not any single number, is the lesson. A creditor who waits one more month at the 90-day mark is not protecting the account. They are discounting it by a third.
Why does a debt lose so much value just by getting older?
Because four things decay at once, and only one of them is visible on the invoice.
The sum owed is the one quantity holding still while everything that would let you collect it quietly comes apart.
How long do I have to collect a cross-border debt?
Less time than you would domestically, and the limit is absolute rather than gradual.
This is why a cross-border creditor faces two clocks, not one. The collectability clock lowers your odds week by week. The limitation clock ends the matter outright when it strikes. A German commercial claim can become unenforceable three years after the year it arose. Both clocks started the day the invoice came due, and neither pauses for deliberation.
Is it still worth collecting an older debt after the fee?
For any debt still on the collectable side of the curve, yes — and one figure settles it.
A debt written off is not simply the face value gone — it is revenue the business must earn again from scratch. A contingency fee charged only on success is the lowest-risk return available. Keeping most of a collected debt will always beat keeping all of an abandoned one.
Your account is somewhere on the curve right now, and if the debtor sits in another country, a second clock is running that you may not have checked. We will assess exactly where the file stands — collectability, evidence, and the enforceable time that remains — and tell you plainly whether to act or let it go.
