Who we are

Data Service OÜ has been operating in Estonia since 2001, specializing in two interrelated areas: accounting services and automation of accounting on the 1C platform.

We immerse ourselves in the client’s business processes and prefer long-term collaboration. Over the years, more than 300 companies have entrusted us with their processes, with 50+ on ongoing accounting services.

Our approach focuses on stability, transparency of accounting, and business manageability, rather than merely closing reporting periods.

Our uniqueness

Immersion in client tasks: we build processes based on real business operations, not universal templates.

Unified team of accountants and developers: fewer gaps, faster results.

Complex automation of accounting and management reporting: non-standard models, high data analysis requirements.

Practicality and responsibility: we design solutions tailored to client processes and provide ongoing support.
