The verdict in three sentences
A recurring payment solution that holds up costs between EUR 8,000 and 30,000 in 2026, depending on billing sophistication and failure handling. The item that pays back most is not the collection but the recovery of declined payments: that is where involuntary churn plays out, often 20 to 40% of total churn. A sharp SaaS vendor therefore steers subscriptions on the recovery rate, not on setup cost alone.
What setup costs in 2026
The budget depends on the pricing model: simple flat rate, or metered usage, tiers, proration, multi-country VAT and smart dunning. 2026 orders of magnitude for Berlin.
| Scope | Delay | Price EUR |
|---|---|---|
| Simple flat subscription | 2-3 weeks | 8,000 - 12,000 |
| Tiers + proration | 3-4 weeks | 12,000 - 18,000 |
| Usage-based billing (metering) | +2 weeks | +5,000 - 9,000 |
| Advanced dunning (retries) | +1-2 weeks | +3,000 - 6,000 |
| Multi-country VAT / compliance | +1-2 weeks | +3,000 - 7,000 |
| Full custom solution | 5-7 weeks | 22,000 - 30,000 |
On top of this come the billing platform fees, charged on collected volume.
Market platform vs custom: 2026 commissions
Stripe Billing and Chargebee cover 90% of SaaS needs. Custom is only justified beyond a certain volume or for atypical billing logic. 2026 comparison (order of magnitude).
| Solution | Recurring cost | Dunning included | Metering | Delay |
|---|---|---|---|---|
| Stripe Billing | 0.5 - 0.8% of volume | yes | yes | fast |
| Chargebee | 0.6 - 0.9% + tier | yes | yes | medium |
| Recurly | 0.7% + subscription | yes | yes | medium |
| Custom | maintenance 4-8k/year | to build | to build | long |
On an MRR of EUR 50,000 (EUR 600,000/year), a 0.7% commission is EUR 4,200/year: negligible against recovered involuntary churn.

Mini case study
Thomas, CEO of a SaaS vendor in Berlin, manages 900 subscriptions at EUR 90/month, an MRR of EUR 81,000. His involuntary churn (expired cards, bank declines) reaches 3.5%/month, around EUR 2,835 of MRR lost each month. He invests EUR 16,000 in Stripe Billing with advanced dunning (scheduled retries, automatic card updates). Involuntary churn drops to 2.1%, recovering around EUR 1,130 of MRR/month, or EUR 13,600/year. Payback is reached in a little over a year, before the time saved on manual billing.
FAQ
What does automated subscription billing cost? Between EUR 8,000 and 30,000 in 2026 depending on complexity (tiers, usage, multi-country VAT). The simple flat rate is fastest and cheapest.
What is involuntary churn? These are subscriptions lost not by customer choice but by payment failure (expired card, limit, decline). It is often 20 to 40% of total churn and is largely recoverable.
Does dunning really pay off? Yes: well-tuned retries and automatic card updates recover 20 to 40% of initially declined payments.
Stripe Billing or Chargebee? Stripe Billing if your stack is already Stripe; Chargebee for complex pricing logic and fine subscription lifecycle management.
Do I need custom? Rarely before EUR 1M annual volume or genuinely atypical billing. Below that, market platforms are faster and cheaper.
