AccelBooks OÜ takes over document processing, invoicing, data registration and day-to-day back-office operations, so your team can stay on the work that actually grows the company.
AccelBooks OÜ provides administrative, record-keeping and operational support. The company does not provide licensed accounting, audit, legal or financial services, and therefore no special licence is required for its activity.
Pick one area or hand over the whole administrative layer. Everything is delivered as an agreed, repeatable process with a named point of contact.

Receiving, sorting, checking and filing incoming and outgoing business documents. Consistent naming, version control and an archive you can actually search. Every document is logged the day it arrives, matched against the order, contract or invoice it belongs to, and filed the same way every single time. Missing signatures, wrong totals and duplicate copies are caught at intake rather than at the end of the quarter. You get one agreed folder structure, a naming rule that survives staff changes, and a short monthly overview of what came in, what went out and what is still waiting for an answer. Incoming post, e-mail attachments and portal downloads all land in the same structure, so nobody has to remember which channel a paper arrived through. Retention periods are tracked as part of the routine: what must be kept for seven years stays where it belongs, and what has expired is cleared out on schedule instead of quietly filling the drive. When your accountant, auditor or bank asks for one specific document, it is found in seconds rather than reconstructed from three different inboxes.

Preparing and issuing sales invoices, tracking what has gone out, chasing what has not come back, and keeping the whole cycle in one clean record.

Entering, verifying and maintaining business data across your systems, spreadsheets and registers, with checks that catch errors before they spread.

Administrative accompaniment for ongoing projects: deadlines, documentation, correspondence, status records and the paperwork nobody wants to own.

The routine operational layer — mailboxes, records, supplier and client files, internal registers — run quietly in the background on a fixed schedule.

Mapping how the administrative work currently happens, removing the duplicated steps, and writing it down so it survives holidays and staff changes.
You describe the administrative load. We ask what is repeatable and what is not.
We put the tasks, volumes, deadlines and responsibilities in writing.
Access, templates and the first cycle run together, so nothing is guessed at.
The work runs on a fixed rhythm with a regular report on what was done.
AccelBooks OÜ was registered in Estonia in March 2024 to do one thing properly: absorb the administrative and operational routine that slows small and mid-sized businesses down.
Most companies do not need another advisor. They need someone who will reliably process the documents, issue the invoices, keep the registers current and answer for the paperwork every single week. That is the work we take on, in English and Estonian, on agreed cycles, with written scope and a named contact.
Every recurring task has a defined process, so results do not depend on memory.
Fixed cycles and deadlines agreed in advance, not whenever there is time.
We are clear about what we do and equally clear about what we do not.
