The verdict in three sentences
A serious Stripe integration for a B2B website costs between EUR 5,000 and 15,000 in 2026, the range driven mainly by Billing (subscriptions), reconciliation webhooks and payment failure handling. The structuring choice is hosted (Checkout) vs custom (Elements): hosted ships in 2 weeks and costs less, custom offers an integrated experience but nearly doubles the budget. On fees, expect 1.5% + EUR 0.25 on European cards, a recurring cost to weigh against SEPA direct debit for B2B.
Stripe building blocks and their cost
Stripe is not a single block: each product adds development. Here are the 2026 ballpark figures per module.
| Stripe block | Role | Integration cost (EUR) | Timeline |
|---|---|---|---|
| Checkout (hosted) | Turnkey payment page | 3,000 - 5,000 | 1-2 weeks |
| Elements (custom) | Form embedded in the site | 6,000 - 9,000 | 3 weeks |
| Billing | Subscriptions, plans, proration | 4,000 - 7,000 | 2-3 weeks |
| Invoicing | Invoices + payment links | 2,500 - 4,000 | 1-2 weeks |
| Webhooks + reconciliation | Reliability, up-to-date statuses | 2,000 - 4,000 | 1 week |
A typical B2B project combines Checkout or Elements + Billing + webhooks, which explains the EUR 5,000-15,000 range. Failure handling (automatic retries, expired cards) is the most underestimated item.
Hosted vs custom: which to choose
The core dilemma is between speed and control of the experience. Here is the 2026 comparison.
| Criterion | Checkout (hosted) | Elements (custom) |
|---|---|---|
| Integration cost | EUR 3,000 - 5,000 | EUR 6,000 - 9,000 |
| Timeline | 1-2 weeks | 3 weeks |
| PCI compliance | SAQ-A (lighter) | SAQ-A EP |
| Experience | Stripe redirect | Embedded in the site |
| Maintenance | Low | Medium |
For most B2B SMEs, Checkout is more than enough and cuts the compliance cost. Elements is only justified if the payment experience is part of your value proposition or the funnel must stay 100% on your domain.
Mini case study
Sophie, head of a B2B SaaS in Bordeaux, wants to bill 140 subscriptions at EUR 89/month. She integrates Stripe Checkout + Billing + webhooks for EUR 11,000. Stripe fees are about 1.5% + EUR 0.25, so on 140 x 89 = EUR 12,460 monthly revenue, a cost of about EUR 222. By automating expired-card retries via Billing, she recovers about 3% of involuntary churn, i.e. 4 subscriptions saved per month (EUR 356). Over a year, those EUR 4,272 recovered cover 39% of the integration, before counting admin time saved.

FAQ
Why pay for integration if Stripe provides code?
Because Stripe's code covers the happy path, not failure handling, reconciliation, reliable webhooks and compliance. That robustness work is most of the budget.
Checkout or Elements for a B2B site?
Checkout in 80% of cases: faster, cheaper, lighter compliance. Elements is justified if you want a funnel 100% integrated with your brand.
How much are Stripe fees in 2026?
About 1.5% + EUR 0.25 on European cards, more on international cards. On high B2B amounts, compare with SEPA direct debit.
Does Stripe handle complex subscriptions?
Yes, via Billing: plans, proration, trials, upgrades. Integrating these cases costs EUR 4,000 to 7,000 depending on the granularity wanted.
How long to deliver?
From 2 weeks (simple Checkout) to 4 weeks (Checkout + Billing + webhooks + failure handling). End-to-end testing is a significant part of the timeline.
