AccSys: Simple Bookkeeping

Data Spec

About this app

Keep your books, keep them private.

AccSys is a simple, proper double-entry bookkeeping app for your phone — accounts, groups, journal entries, ledgers, and account summary/trial balance, done the correct way rather than a stripped-down income-expense tracker.

Fully offline. No account, no sign-up, no server — your data stays on your device, always.

- Proper double-entry accounting: accounts, groups, ledgers, trial balance
- Export any report as CSV or HTML — your data is always yours to take with you
- Nothing to configure, nothing sent anywhere — works the moment you install it

Built for individuals and small shop owners who want honest personal books without complexity or data collection.

Running a GST-registered business and outgrowing personal bookkeeping? Data Spec also builds dsGST, a full GST billing and accounting solution — see www.dataspec.info for details.
