Who is the buyer for this idea?

Steuerberater or bookkeeper at a 5-50 person Kanzlei. Reach them through steuerberatertag and datev-partner events. Skip broad SEO on day 1 — start where your first 20 customers already hang out.

How would you monetize it?

€49-199/mo per bookkeeper. Pricing is the most under-thought step for these buyers, so anchor to the outcome you replace, not the tool you resemble.

DATEV opened newer APIs in 2024; startups can finally integrate cleanly. That's the underlying shift — if it fades, so does the wedge.

What tech stack would you use?

Suggested stack: Next.js, Supabase EU, DATEV API, and Lovable AI. You can build the v1 in weeks on this stack; the moat is workflow depth, not framework choice.

Who are the incumbents I'd be competing with?

Study Candis, GetMyInvoices, and sevDesk — read their 1-star reviews, price ladder, and onboarding. That's where your positioning lives.
