Kontau is simple, hosted double-entry accounting built for freelancers and solo entrepreneurs. Your books stay balanced by construction — no fiduciary retainer, no accounting course, just clean records you can trust.

Every entry needs a debit and a credit that match — the ledger simply won't let your books go out of balance.
Seeded from the standard Swiss chart in your language. No setup, no guessing which account a coffee with a client goes under.
A live trial balance and reports, computed straight from what you’ve posted — no spreadsheet, no waiting on someone else.
Posted an invoice wrong? Void it and repost — a clean, traceable trail instead of an eraser and a headache.
Attach receipts straight to an entry. No shoebox, no folder of PDFs to hand off at year-end.
Single-tenant by design — your ledger isn’t sitting in a shared spreadsheet or a fiduciary’s inbox.
Invoice a handful of clients and want proper double-entry books without learning accounting.
Designers, developers, photographers, craftspeople — anyone billing for their own work, solo.
Outgrowing a spreadsheet but not ready to pay a fiduciary a monthly retainer just to stay compliant.
If tax season usually means a scramble and an expensive accountant bill, this is built to replace both.
