The verdict in three sentences
A B2B payment stack in Amsterdam (Stripe cards, GoCardless/SEPA, deferred payment) integrates for 8,000 to 25,000 EUR in 2026, in 3 to 6 weeks. The integration cost is marginal against the real stake: DSO (average payment delay) and the time spent chasing and reconciling transfers. Automating SEPA direct debits and deferred credit gains as much in cash flow as in accounting hours.
B2B payment methods and their costs
In B2B, bank transfer dominates but is slow to reconcile; cards are handy below a certain amount; SEPA direct debit (GoCardless) automates recurring collections and instalments. The right stack combines all three by amount and customer.
| Payment method | 2026 fees (order of magnitude) | B2B use |
|---|---|---|
| Card (Stripe) | 1.4% + 0.25 EUR (EU) | Small/mid amounts, speed |
| SEPA direct debit (GoCardless) | 0.25-1 EUR/transaction (+1%) | Recurring, instalments, credit |
| Bank transfer | ~0 EUR but manual reconciliation | Large amounts, framework accounts |
| Deferred payment (30/60 d) | Cash-flow cost + credit insurance | Approved customer accounts |
| Wallet / Apple Pay | Card fees + Stripe | International, mobile |
The technical integration covers: payment-method tokenisation, SEPA mandate management, instalment schedules, automated dunning, accounting reconciliation and status webhooks.
| Integration item | 2026 range (EUR) |
|---|---|
| Scoping & payment flows | 1,500-3,000 |
| Stripe integration (cards + wallets) | 2,500-6,000 |
| GoCardless / SEPA integration | 2,500-7,000 |
| Deferred payment & credit | 2,000-6,000 |
| Reconciliation & webhooks | 1,500-4,000 |
| Total | 8,000-25,000 |
Impact on DSO
DSO measures how many days you wait for your money. Every day saved frees cash. Here is the typical effect of an automated stack in 2026.
| Metric | Before (transfer + manual dunning) | After (SEPA + auto instalments) |
|---|---|---|
| Average DSO | 52 days | 34 days |
| Dunning time/month | 22 h | 6 h |
| Reconciliation error rate | 4% | 0.5% |
| Late > 30 d | 18% of invoices | 7% |
Mini case study
Marc, CFO of a building-materials trader in Amsterdam, invoices 1.8M EUR/month B2B with a DSO of 52 days. Cutting DSO to 34 days frees: 1.8M x (18/30) = ~1.08M EUR of cash recovered permanently.
The integration cost 17,000 EUR. Internally, the accountant spent 22 h/month on dunning (loaded cost ~30 EUR/h, i.e. 660 EUR/month); it drops to 6 h (180 EUR/month), saving 5,760 EUR/year. Between the cash-flow gain and the freed hours, the stack pays for itself in under 6 months.
