Quittungsbuch

An offline-first cash-spending tracker built for German consumers who want to keep using cash, with a community-mapped directory of cash-accepting shops and ATMs so users can find places that still take notes and coins.

Target user

German consumers who actively want to keep paying cash and tracking those payments

Features
  • Manual receipt entry in under five seconds — amount, category, photo of the receipt, all stored locally
  • Crowd-sourced map of shops, restaurants, and markets that accept cash, with a 'verified cash-friendly' badge for confirming buys
  • ATM and bank-branch finder with up-to-date counts and recent-user reports of cash availability
  • Weekly cash-flow summary that helps users see how much they're funneling through card networks vs. paper
Why now

Bargeld is trending in Germany because consumers noticed ATMs disappearing, shops going card-only, and EU rules shifting — and the BR24 piece shows the public is hungry for tools that keep cash practical rather than treating its decline as inevitable.

Demand
6/10

Bundesbank 2025 study shows 55% of purchases already cashless (so 45% still cash) with a real Bundestag/public debate ('Bargeld muss bleiben') covered by Focus, NDR and Bundesbank Monatsbericht; demand exists but is structurally shrinking.Zahlungsverhalten in Deutschland 2025 | Deutsche BundesbankDebatte über Bargeld und Potenziale von - Deutscher Bundestag

Whitespace
5/10

Crowded 'Haushaltsbuch' category with many competitors (CashOwl explicitly offline-first, plus Finanzguru, Outbank) and dedicated cash counters (Bargeldrechner, CashCounter); community cash-accepting shop/ATM directory angle isn't validated as a gap and could be replicated via OpenStreetMap.CashOwl — Haushaltsbuch mit WeitblickBeste Haushaltsbuch-App 2026 im Test | Financer

Monetization
4/10

Category is dominated by free/freemium Haushaltsbuch apps (Handelsblatt, Wiwo, Finanzfuchs comparisons emphasize free options); niche single-purpose utility with weak willingness to pay.5 kostenlose Haushaltsbuch Apps im Vergleich 2026 - HandelsblattDie besten Haushaltsbuch Apps 2026 im Vergleich

Longevity
4/10

Bundesbank 2025 confirms 55% cashless and rising trend; even with political pushback the secular direction is toward less cash, eroding the addressable problem over time.Zahlungsverhalten in Deutschland 2025 | Deutsche BundesbankVerschwindet das Bargeld nach und nach aus unserem Alltag?

Feasibility
5/10

Offline-first cash tracker is straightforward (matches CashOwl pattern); the community-mapped shop/ATM directory needs network effects, moderation, and ongoing data curation which is the hard part.CashOwl — Haushaltsbuch mit Weitblick
