Tasur

Product

A real ledger, built to Estonian rules.

Tasur is a complete general ledger. Its engine treats Estonia as a first-class jurisdiction, not as a translation.

The ledger

  • A complete list of accounts
  • Sales invoices, purchase invoices and expenses
  • Bank statement import (CSV, ISO 20022 camt.053) and reconciliation
  • An inbox for receipts and invoices, with automatic data extraction, in the paid tiers
  • Projects and segment reporting, in the Pro tier

Reports required by law, at launch

  • KMD, the monthly VAT return, with KMD INF file export
  • TSD, the monthly payroll tax return, as file export
  • Generation of the annual report in the XBRL file format

At launch, submission works as file export: Tasur prepares the files, and you upload them under your own e-MTA login. Automatic submission over X-Road becomes part of the Pro tier, once it is available.

Six screens, one engine.

Real screens, captured from the live product. Nothing on this page is a sketch.

Cashbook — money in, money out.
Invoices and receivables.
A real library of reports.
The engine already produces a statutory tax return in its home market: this is the Australian activity statement worksheet (BAS). The Estonian KMD is built on the same machinery.
A chart of accounts with real depth, grouped by type. Shown with the Australian standard chart; the Estonian chart of accounts ships with Tasur.
Hours in a weekly grid, by day and by project. Approved hours become a draft invoice.

The screens show the engine in its Australian edition. Estonian screens are on the way.

E-invoices

Since 1 July 2025, any buyer registered as an e-invoice recipient may demand an e-invoice from its supplier. Tasur sends and receives e-invoices through the operator network. One integration reaches the whole network, because the operator networks are connected to each other.

One engine, every border

Tasur runs on SAE Books, an engine for which jurisdictions and tax families are native. The same engine that prepares the Estonian KMD can also submit an Australian activity statement. Multi-jurisdiction books are part of the Pro tier.

Host it yourself. The exit is always open.

The engine is source-available. By default, we host it for you in the European Union, with no United States parent company in the data path. But you can leave any day and take the whole engine with you. Because the exit is open, the hosting can be trusted.

An accounting core. Services around it.

The ledger keeps the books. Everything else — the document inbox, bank import, payroll — talks to it over the API. Replace any part; the books stay yours.

A documented API

Every endpoint is documented and can be tried in the browser. Token authentication and idempotency keys.

Webhooks

Subscribe to events. Signed payloads, automatic retries, and a full log of deliveries.

The audit trail

Every change, from the screen or through the API, is recorded together with who did it and what changed.

For developers

The full API is included in every paid tier, starting with the cheapest. Every function is available. Webhooks are included. The free-of-charge tier is the ledger without automation.

Every paid plan ships the full API. Even the cheapest.
