buchhalter.app

Receipts accumulate faster than you can sort them. buchhalter.app takes care of that for you: simply photograph the receipt, and you're done. The rest happens in the background.

The app is the mobile complement to buchhalter.app—the secure filing system between you and your firm.

Scan receipts, don't type them in

The built-in document scanner automatically detects the edges of the receipt, straightens skewed images, and takes the picture as soon as it's in focus. Text recognition and QR code recognition run directly on the device—no internet connection is required.

Austrian cash register receipts with RKSV QR codes are read automatically during scanning. The amount and tax rate are extracted directly from the code itself.

Even while you're holding the receipt, the app checks sharpness, contrast, and framing—and tells you if a second shot would be better.

Effortless organization

Each receipt is automatically filed by year, quarter, and month. You can create, rename, and nest your own folders. Search, sorting, and tags help you find what you need.

What you store privately stays private—even from your firm. You decide whether each document is shared.

Securely stored

All data is stored within the European Union. The archive is designed to comply with the seven-year retention requirement under Section 132 of the Austrian Federal Fiscal Code (BAO), and every access is logged.

Log in without a password

Log in with a passkey, ID Austria, or a link sent via email. There's no password to lose.

More than just receipts

Create invoices—with payment QR codes (EPC/Stuzza) so customers can pay in seconds. The invoice data is embedded (ZUGFeRD/Factur-X, EN 16931) and therefore machine-readable.

Track time spent—with optional location for each entry. The location is only requested upon your explicit input, never automatically or in the background.

Record purchases and projects, keep track of inventory, and assign receipts to projects.


Record purchases and projects, keep track of inventory, and assign receipts to projects. All your questions in one place

Your firm can request a missing document or obtain approval. You see all open requests in one place and can respond with a single tip—instead of a back-and-forth email exchange.

Access and pricing

buchhalter.app is currently available by invitation only. You cannot log in without your firm's access credentials.

The basic version is free for clients. Full functionality is tied to a subscription plan that your firm purchases separately from the app—nothing is sold within the app itself.

The app is a supplement, not a requirement: buchhalter.app works entirely in your browser. The app brings the scanner and document recognition directly to the device.
