The brutal math of how fast a collectible invoice becomes a bad debt — in six chapters.

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.

The question every CFO should answer in one sentence

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.

The short answer

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.

Chapter I · The Decline Curve

Commercial B2B recovery rates, benchmarked across CCAA, NACM, CLLA, and Atradius data, follow this shape:

Invoice Age	Recovery Probability
0–30 days	90–98%
31–60 days	75–85%
61–90 days	70–80%
91–180 days	45–55%
6–12 months	30–40%
12+ months	20–30%
24+ months	Sharp plunge toward write-off

These are directional benchmarks, not audited totals. Exact probabilities vary by industry, customer size, and whether the debt is disputed. But the shape of the curve is remarkably consistent across datasets.

What the curve tells you: recovery probability is not a linear function of time. There are two cliffs — one around day 90, another around day 180 — separated by the single steepest descent on the curve.

Chapter II · The 90-Day Cliff

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.

Chapter III · Not All Receivables Decay Alike

The decline curve varies by sector. Commercial B2B sits at the top. Consumer collections are structurally harder. Healthcare is the toughest.

Segment	Typical Recovery Range
Commercial B2B	30–70%
Consumer (general)	20–40%
Healthcare consumer	15–25%
Utilities consumer	20–35%
Property management	20–40%

Why B2B leads: business debtors have identifiable assets, named directors, registered legal addresses, commercial reputations to protect, and often legal representation. All of that gives a professional recovery team meaningful leverage. Consumer debtors — especially in healthcare — often have none of those attributes, and consumer protection laws reduce the collection toolkit further.

For creditors, the implication is straightforward: B2B receivables are the highest-yield segment to chase, but only if you chase them on time.

Chapter IV · The International Tax

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.

Chapter V · The Four Forces Bending the Curve

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

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.
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.
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.
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.

Chapter VI · The Intervention Window

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.

II	90-day cliff (90d → 180d drop)	−25 pp
III	B2B vs healthcare spread	70% vs 25%

How Collecty handles the curve

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.
