The verdict in three sentences
Setting up B2B recurring subscription billing costs 3,000 to 10,000 EUR excl. VAT to integrate, plus a tool such as Stripe Billing at 0.7% of billed volume or Chargebee from 600 USD per month. The main gain comes from fewer failed payments, which typically drop from 4% to 1% thanks to SEPA direct debit, smart retries and automated dunning. For 300 monthly subscriptions, the project pays back within a few months.
Stripe Billing, Chargebee or in-house billing: 2026 comparison
The choice depends on volume, plan complexity (tiers, usage, add-ons) and whether you need several payment gateways.
| Criterion | Stripe Billing | Chargebee | In-house build |
|---|---|---|---|
| Tool cost | 0.7% of billed volume (Billing) | from 600 USD per month (Performance plan), free up to a certain volume | 0 license |
| Card fees (2026 order of magnitude, EU cards) | 1.5% + 0.25 EUR | Depends on chosen gateway | Depends on gateway |
| SEPA direct debit | Yes, about 0.35 EUR per debit | Yes, via Stripe, GoCardless or others | To be built |
| Proration, trials, tiers | Native | Native, more advanced | To be built |
| Dunning and retries | Smart Retries, automatic emails | Dunning configurable by segment | To be built |
| Multi-gateway | No | Yes | Possible |
| Best for | 50 to 2,000 subscribers, simple plans | Complex plans, multiple entities | Very specific cases |
For 300 monthly subscriptions and 3 or 4 tiers, Stripe Billing is often the best balance of cost and speed. Chargebee becomes relevant above 1,000 subscribers or with multi-currency usage-based billing.
What the integration includes
| Item | Scope | 2026 budget |
|---|---|---|
| Plan modeling | Products, prices, tiers, discounts, trial period | 500 to 1,500 EUR |
| Signup flow | Checkout page, SEPA mandate, card, EU VAT | 800 to 2,500 EUR |

Watch out for e-invoicing: the French reform requires all companies to receive electronic invoices from September 2026, with issuing phased in through 2027. Check that your tool can transmit through an approved platform.
Why failures drop from 4% to 1%
| Failure cause | Share of failures | Fix |
|---|---|---|
| Expired card | 30 to 40% | Automatic card updates (account updater) |
| Insufficient funds | 20 to 30% | Retries on optimized dates |
| Strong authentication declined | 10 to 20% | 3D Secure confirmation link sent by email |
| Blocked or lost card | 10 to 15% | Reminder with link to the customer portal |
| Card payment for large amounts | Variable | Switch to SEPA direct debit, failure rate under 1% |

After a 7,000 EUR Stripe Billing integration, with 70% of customers moved to SEPA direct debit, failures fall to 1%, or 1,350 EUR per month. Gross gain: 4,050 EUR monthly. Stripe Billing at 0.7% of 135,000 EUR costs 945 EUR per month, but transaction fees fall because SEPA costs about 0.35 EUR per debit instead of 1.5% on cards. Estimated net gain: 3,100 EUR per month, a payback in just over 2 months.
FAQ
Is SEPA direct debit suitable for B2B?
Yes, the SEPA mandate (Core or B2B scheme) is the standard for business subscriptions. The refund window is 8 weeks under Core and none under B2B, which secures amounts above 1,000 EUR.
Do we need to change invoicing software?
Not necessarily. Stripe Billing or Chargebee issue the invoices, which are then synced to your accounting tool. The connector costs 500 to 2,000 EUR depending on the tool.
How long does setup take?
Plan 3 to 6 weeks, including 1 to 2 weeks to collect SEPA mandates from existing customers. The migration campaign usually moves 60 to 80% of customers within a month.
Can we handle usage-based billing?
Yes, both tools accept usage meters (users, interventions, GB). Integrating usage tracking adds 1,500 to 4,000 EUR.
What is the total annual cost for 300 subscribers?
With Stripe Billing, about 11,000 EUR a year for the tool plus 2,500 to 6,000 EUR in transaction fees depending on the SEPA share. With Chargebee, from 7,200 USD a year plus gateway fees.
