SimplBooks is developing machine-to-machine integrations for its cloud-based accounting software with the services of the Estonian Tax and Customs Board (MTA), the Centre of Registers and Information Systems (RIK), and the e-invoicing operator Telema.

As a result of the project, entrepreneurs and accountants will be able to submit TSD (tax and social security) and KMD (VAT) declarations, register employees in the Employment Register (TÖR), prepare annual reports, and send and receive e-invoices directly through SimplBooks.

These integrations will reduce manual work, duplicate data entry, and administrative burden while improving data quality.

Project name: “APA Integrations (MTA, RIK, Telema)”.
Project No.: 2021-2027.1.02.26-0928.

The project has received funding of €128,487.74 and is supported by the Estonian Business and Innovation Agency (EIS).

Project implementation period: 14 August 2026 – 31 December 2027.
