The €1 Million Mistake: What Writing Off a Single Invoice Actually Costs Your Company
This video examines the wider business cost of writing off an unpaid B2B invoice, from replacement revenue to pressure on cash flow. It explains how to assess internal collection costs, financing risks and recovery options before accepting a loss.
Key takeaways
- Divide the written-off amount by your net profit margin to estimate the revenue needed to offset the lost profit.
- An hour of payment chasing each working day adds up to 260 hours annually, costing €15,600 at a loaded hourly rate of €60.
- Weak payment enforcement can undermine payment discipline, while ageing receivables can restrict borrowing capacity.
- A tax deduction offsets only part of a bad-debt loss; compare that benefit with the potential net proceeds from collection.
- Write-offs may be appropriate when assets are unavailable, pursuit costs outweigh recovery prospects or a legitimate dispute warrants settlement.
What this video covers
The video teaches finance teams to evaluate an invoice write-off as more than an accounting adjustment. Its starting point is the relationship between lost profit and net margin: offsetting a €100,000 loss requires €1 million in revenue at a 10% margin, or €2 million at 5%. It then examines costs that can remain outside the write-off discussion. Routine payment chasing consumes staff time, with one hour per working day amounting to 260 hours annually. At €60 per hour including employment overheads, that represents €15,600 before considering other work those employees could have done. The video also connects payment enforcement with customer behaviour and financial flexibility. Tolerating non-payment can weaken collection discipline, while older receivables and increased write-offs can affect borrowing terms. In receivables-backed facilities, invoices more than 90 days old are often ineligible for financing. Cash shortages can also delay supplier payments and investment. Finally, it puts tax relief in perspective: a €100,000 deduction at a 25% corporate tax rate provides a €25,000 benefit, not full compensation. The decision should weigh potential collection proceeds and fees against genuine recovery barriers. Where the debtor has no available assets, pursuit is uneconomic or the debt is legitimately disputed, a write-off or settlement may be justified.
