If a €100,000 invoice is 90 days past due today, how much of it is still realistically collectible? Most finance leaders know the debtor, the excuses, and the internal chasing history. Far fewer can sketch the decline curve from memory. This article does exactly that — in one briefing, one curve, and six numbers worth remembering.

If a $100,000 invoice is 90 days past due today, what percentage of it will you actually collect? Most finance directors cannot answer this within 15 points. The industry does not hide the data — it just rarely visualises it. This briefing puts the numbers on one curve and shows exactly where the cliffs are.

B2B recovery rates decline in a predictable, brutal pattern as invoices age. At 30 days past due, roughly 94% of the invoice is still collectible. At 90 days, around 75%. At 180 days, you are down to 50%. Beyond one year, 30% is optimistic. Every week of delay past day 90 costs approximately one percentage point of expected recovery. The highest-return window to engage professional collection is between day 60 and day 90 — after internal dunning has failed, but before the 90-to-180-day cliff takes 25 points off the file.

Between day 90 and day 180 the recovery rate falls from roughly 75% to roughly 50% — a 25 percentage point drop over 13 weeks. Roughly one point per week.

This is the single most expensive stretch of procrastination in commercial finance. A creditor who waits “one more month” past day 90 — a common pattern — has effectively given up four points of recovery on the invoice. Six more weeks and it is ten points.

The rule of thumb: if an invoice has passed day 90 and you have not seen a payment commitment from the debtor, the file should already be in professional recovery. The creditor-relationship argument (“let us keep trying internally”) stops being economic after day 90.

Geography adds a second layer of decay on top of time. Inside the EU, with Brussels I Recast and the European Enforcement Order, a domestic baseline of 100% holds roughly 85% across borders. Across to a common-law OECD jurisdiction (UK, US, Canada, Australia), you drop to 70–80%. Into emerging markets with weaker enforcement regimes, the same day-90 file might recover 40% or less.

This cross-border penalty is what network models exist to mitigate. A creditor handing a Spanish invoice to a German agency, or a Dubai invoice to a US agency, is often paying the full distance tax. A creditor using a network with native partners in each jurisdiction recovers closer to the domestic baseline — which is a material delta on a €100,000 file.

For context on the wider market dynamics — industry size, segment structure, country-by-country breakdown — see our European debt collection market data briefing.

The decline is not random. It is the compounding effect of four structural forces:

1. Solvency deterioration. Debtor cash positions worsen over time. Today’s willing-but-slow payer becomes next quarter’s insolvent estate. Commercial insolvency filings rose across several European jurisdictions over the last two years.
2. Memory fade. Staff turnover erases institutional context. The AP manager who signed the purchase order moves on. The new one has no reason to prioritise your invoice over ten others. Internal context has a rough six-month half-life.
3. Competing creditors. You are not the only creditor chasing this debtor. Every week, another supplier, tax authority, or utility joins the queue ahead of you. First-mover advantage is real.
4. Documentation decay. Email threads get archived, delivery notes get misfiled, signatures get disputed, and the evidence base weakens with every quarter. By month 18, reconstructing the contractual paper trail can cost more than the invoice itself.

All four forces compound. They are why the curve bends the way it does — and why doing nothing is never actually neutral.

The single highest-return placement window is between day 60 and day 90.

• Before day 60 — internal dunning has not yet been fully exhausted. Professional collection is premature.
• Between day 60 and day 90 — internal efforts have demonstrably failed, but the curve has not yet bent sharply. Expected recovery is still 75%+.
• After day 90 — you are now paying the daily decay. Every week costs roughly one point.
• After day 180 — you have slipped below 50%. Legal action starts to look more attractive than continued amicable effort.

The economics are binary. A file placed at day 90 recovers ~75%. The same file placed at day 180 recovers ~50%. On a €100,000 invoice that is €25,000 left on the table because the creditor waited 90 more days.

What percentage of B2B invoices are collectible after 90 days?

Approximately 70–80% of B2B invoices at 90 days past due remain collectible with professional recovery, per Commercial Collection Agency Association (CCAA) and NACM industry benchmarks. That drops to 45–55% at six months and 20–30% at twelve months. The decline is steepest between day 90 and day 180.

How does recovery rate vary by invoice age?

The decline curve for commercial B2B: 94% at 30 days, 80% at 60 days, 75% at 90 days, 50% at 180 days, 35% at one year, 15% at two years. The curve is not linear — there’s a pronounced drop between day 90 and day 180, and a second plunge past day 365.

When should I send a B2B invoice to collections?

The optimal window is between day 60 and day 90 past due — after internal dunning has clearly failed, but before the curve bends sharply. Waiting past day 90 costs roughly one percentage point of expected recovery per week of delay. Waiting past day 180 drops you below 50% collectability.

Do B2B recovery rates differ from consumer recovery rates?

Yes — significantly. B2B recovery rates typically run 30–70%, consumer rates 20–40%, and healthcare consumer rates just 15–25%. The difference is structural: business debtors have identifiable assets, named directors, registered addresses, and commercial reputations to protect, all of which give a recovery team meaningful leverage.

What’s the recovery rate for cross-border B2B debt?

Inside the EU, roughly 85% of the domestic baseline. Across to OECD common-law jurisdictions (UK, US, Canada, Australia), around 70–80%. Emerging markets with weaker enforcement can drop to 40% or less. Network-based recovery models using native in-country partners mitigate most of this penalty.

How much does every week of delay cost on an overdue invoice?

Roughly one percentage point of expected recovery per week, past day 90. On a €100,000 invoice, that’s approximately €1,000 of expected value per week of procrastination. The math compounds: waiting 13 weeks past day 90 costs you 25 points, or €25,000 on that same invoice.

Collecty operates as an international B2B collection network across the EU, the UK, the UAE, and North America. For creditors with files sitting in the 60–90 day window, a single case manager coordinates placement, runs the amicable phase in the debtor’s local jurisdiction and language, and escalates to legal only when economically justified.

Typical engagement: mandate intake within 4 working hours, amicable recovery inside 10–15 business days of placement. Pricing is commission-only on recovered sums during the amicable phase. Cross-border cases route through native partners to minimise the jurisdictional penalty.

Contact Collecty for a free case review. We return an assessment within one working day — and place the file into the window before the cliff.
