The verdict in three sentences
A payment failure rate of 9% at B2B checkout means one euro of revenue in eleven is never collected on the first attempt. By optimizing the funnel with 3D Secure 2, smart retries and network tokens, a platform in Amsterdam cuts this rate to 3% in 2026 for a budget of 6,000 to 15,000 EUR. The ROI is immediate because every recovered failure point translates directly into additional revenue.
Where payment failures come from
Before paying for optimization, you must identify the causes. In B2B, high baskets trigger more bank declines and authentication friction.
| Failure cause | Typical share | Correction lever |
|---|---|---|
| Bank decline (soft decline) | 30-40% | Smart retry + network tokens |
| 3D Secure friction | 20-30% | Optimized 3D Secure 2 / exemptions |
| Expired / updated card | 10-15% | Account updater |
| Timeout / technical error | 10-15% | Funnel robustness + webhooks |
| Funds / company limit | 10-15% | Alternative payment (transfer, SEPA) |
Soft declines (temporary refusals) are often the biggest reservoir: a simple retry at the right moment recovers a large share of these transactions.
Optimization budget and expected result
The cost depends on the depth of the work. 2026 order of magnitude for a B2B platform.
| Item | Range (EUR) | Effect |
|---|---|---|
| Optimized 3D Secure 2 + exemptions | 2,000 - 4,000 | -30% auth friction |
| Smart retries | 2,000 - 4,500 | +40% soft declines recovered |
| Network tokens + account updater | 1,500 - 3,500 | -50% expired-card failures |
| Alternative payments (SEPA/transfer) | 1,500 - 3,000 | Safety net for large amounts |
| Total | 6,000 - 15,000 | 9% -> 3% failure |
Moving from 9% to 3% failure means recovering 6 points of revenue on the volume that was failing. On a high-volume platform, the investment often pays back in a few weeks.

Mini case study
Sophie, e-commerce director of a B2B platform in Amsterdam, processes 4.5M EUR of payments/year with a 9% failure rate. That represents about 405,000 EUR of failed transactions, part of which is permanently lost. She invests 12,000 EUR in checkout optimization.
Result: the failure rate falls to 3%, recovering 6 points i.e. 270,000 EUR of volume that now completes. Estimating that 70% of this volume was previously lost, that is about 189,000 EUR of revenue recovered per year. The 12,000 EUR investment pays off in under a month, with a recurring net gain each following year.
FAQ
Is a 9% failure rate abnormal? In B2B with large baskets, 8-10% is common without optimization. Well-optimized platforms run between 2 and 4% in 2026.
What is a smart retry? It is the automatic re-attempt of a declined payment at the best moment (timing, channel), recovering a large share of soft declines without customer action.
Do network tokens really improve the rate? Yes, they replace the card number with an automatically updated token, sharply reducing failures from expired or reissued cards.
Doesn't 3D Secure 2 add friction? Well configured with exemptions, it authenticates without a visible step in most cases while securing large amounts.
How soon do you see the result? Optimization ships in 4 to 6 weeks and the effect on the failure rate is measurable within the first weeks of production.
