It depends on which €8,000 you are looking at.
The €8,000 on the invoice is not the number that matters. The number that matters is what it costs your business to replace it. At a 10% net margin, writing off €8,000 requires €80,000 in new revenue — new business found, contracted, delivered, and collected — to restore your position. That is the real question: is it easier to find €80,000 in new sales, or to recover €8,000 already owed?
For most businesses, the arithmetic is not even close.
When it is worth chasing
If the debtor is solvent and the debt is undisputed, a contingency collection agency recovers the money at zero upfront cost. At a 20% contingency (higher than average, reflecting the smaller amount), you net €6,400. Against the alternative — €80,000 in new sales — the return on effort is not comparable.
If the debtor is in a jurisdiction with efficient fast-track procedures, the legal cost is minimal. Germany's Mahnverfahren costs €36 in court fees for an €8,000 claim. The Dutch kort geding is similarly inexpensive. Even with an agency's contingency fee, the net recovery exceeds the write-off benefit by a multiple.
If the debtor owes you a small amount but is a repeat customer, collection sends a signal that your payment terms are not optional. Writing off a small debt teaches the client that non-payment below a certain threshold carries no consequences. The next unpaid invoice will be larger.
When it is not
If the debtor is in a jurisdiction where legal enforcement costs exceed the debt value — where filing fees, translation costs, and local counsel retainers would consume the recovery — the economics do not support it. This is rare in the EU and common-law countries but real in certain jurisdictions with slow, expensive court systems.
If the debtor is insolvent, the amount is irrelevant. There is nothing to collect. The assessment will tell you this before any engagement.
If the debt is genuinely disputed on substance — not a tactical dispute raised to delay payment, but a real disagreement over scope, quality, or delivery — and resolving the dispute requires litigation, the legal costs on an €8,000 claim can exceed the recovery. At that point, the write-off and the tax deduction are the rational choice.
The portfolio effect
One €8,000 write-off is a rounding error. Twelve of them in a year is €96,000 — nearly €1 million in replacement revenue at a 10% margin. Small debts written off individually are a habit. Aggregated, they are a strategy problem.
Companies that systematically write off debts below a threshold are training their customer base. The threshold becomes known. Clients learn that invoices under €10,000 can be ignored with no consequence. The average amount of the ignored invoices creeps upward.
A collection policy that applies to all overdue invoices — regardless of amount — eliminates this. The message is consistent: payment terms are terms, and non-payment triggers a process. The cost of enforcing this policy on a few small debts is paid for many times over by the larger debts that never become overdue because the client already knows what happens.
The honest answer
If the debtor is solvent and the jurisdiction is accessible, yes — chase it. The contingency model means you pay nothing if recovery fails. The margin-replacement arithmetic makes even a €5,000 recovery more valuable than it appears on the aging report.
If the debtor is insolvent or the jurisdiction is inaccessible, no — write it off deliberately, take the tax deduction, and move forward.
The wrong answer is the one most companies give: neither collecting nor writing off, leaving the receivable on the spreadsheet until it ages past the point of recoverability. Indecision costs more than either alternative.
