FAQ
What clients usually ask
How long does it take?+
8-12 weeks — depends on number of external APIs and business logic complexity.
Which payment provider — Stripe or PayPal?+
Stripe for modern SaaS / subscriptions. PayPal for classic shops or DACH-specific. Both work.
Can I add a 3rd external API later?+
Yes — hourly (95 EUR/h) or flat rate per integration (290-690 EUR).
How is GDPR handled?+
Data export (Art. 15) and deletion concept built-in, GDPR-compliant cookie banner, DPA contract with you, servers in Germany (Hetzner Falkenstein/Helsinki).
What if my requirements grow before build?+
We clarify scope in the briefing. Extensions before start: additional quote. During build: small adjustments OK, bigger ones as change request.
What does a second language (e.g. French) cost?+
Content structures are already multilingual — you translate in admin or via DeepL. Pure technical adjustment 290 EUR.
