Online Bookkeeping for Estonian OÜs
Cloud-based bookkeeping for Estonian companies — how digital document capture, Merit Aktiva, LHV bank feeds, e-invoices, and EMTA integration create a completely paperless bookkeeping workflow without any office visits.
Why Estonian Bookkeeping Is Perfectly Suited to Being Online
The Estonian Tax and Customs Board (EMTA) has processed all declarations electronically for over two decades. KMD, TSD, and all EMTA correspondence happen through the e-Tax portal — there is no paper submission option for routine tax filings.
Merit Aktiva, Estonia’s leading accounting platform, is a cloud system accessible from any browser. It connects directly to the EMTA e-Tax portal via API for declaration submission, and to Estonian banks via bank feed APIs for automatic transaction import. No local installation required.
LHV Pank’s LHV Connect API feeds every transaction from your business account directly into Merit Aktiva — daily, automatically. For LHV clients, bank reconciliation becomes a review task rather than a data-entry task. SEB and Coop Pank also offer integration.
When a supplier sends you an Estonian e-invoice through the Finbite or Telema network, it arrives directly in Merit Aktiva as a structured XML invoice — pre-populated with all fields. No manual entry, no misreading of figures, no lost emails.
Annual reports, board resolutions, service agreements, and employment contracts are all signable with the Estonian e-ID card, Mobile ID, or Smart-ID via DigiDoc4. Legal equivalence to wet signatures under the Digitaalallkirja seadus (Digital Signatures Act) is established in Estonian law.
Estonia’s Accounting Act explicitly permits accounting records to be kept in electronic form throughout the 7-year retention period, provided they are legible, tamper-evident, and backed up. No paper archive is required — a well-organised cloud folder or Merit Aktiva is legally sufficient.
What does ‘online bookkeeping’ actually mean for an Estonian OÜ? It means your entire bookkeeping workflow — from capturing source documents to posting transactions to delivering the trial balance — happens digitally, without printing or physical document handling. Bank entries arrive automatically via API. Invoices arrive by email or e-invoice network. Every entry in Merit Aktiva is linked to its digital source document. You can view your general ledger in real time from anywhere in the world.

The Zero-Paper Month — What a Typical Month Looks Like
For a client with LHV bank account, a mix of e-invoices and PDF invoices from suppliers, and services sold to Estonian and EU clients, a typical month in our online bookkeeping service looks like this:
| Day | Activity | Who Does It | Paper Involved? |
|---|---|---|---|
| 1–5 | Bank transactions auto-imported via LHV Connect API | Automatic | None |
| Ongoing | Client forwards supplier invoice PDFs as emails to accounting address | Client — 5 sec per invoice | None — digital originals |
| Ongoing | E-invoices from Estonian suppliers arrive directly in Merit Aktiva | Automatic — Finbite/Telema network | None — XML is the primary document |
| 5th | Client sends any remaining documents (receipts, payroll changes) | Client — email | None — photos and scans |
| 5th–10th | Bookkeeper reviews all auto-imported bank entries; categorises and posts | Bookkeeper in Merit Aktiva | None |
| 5th–10th | Bookkeeper posts purchase and sales invoices; applies VAT codes | Bookkeeper in Merit Aktiva | None |
| 7th–10th | Bookkeeper reconciles bank; resolves any unmatched items | Bookkeeper in Merit Aktiva | None |
| By 10th | Trial balance exported to PDF; emailed to client | Bookkeeper | None — PDF email |
| Year-end | Annual report prepared in Merit Aktiva; sent for digital signature | Bookkeeper + client signs with e-ID | None — DigiDoc signature |
Section 2 — Digital Document Capture
Every document type and the correct digital method for capturing it
The Source Document Requirement — Met Digitally
The Raamatupidamise seadus §6 requires every accounting entry to be supported by a source document (algdokument). The document must verify that the transaction occurred, the parties involved, the amounts, and the date. Under Estonian law, a digital copy — whether a PDF, photograph, or XML file — satisfies this requirement as long as it is legible and the digital file itself is retained for 7 years.
This means you do not need to file paper invoices or keep physical receipt binders. A photographed receipt emailed to your accountant and stored in Merit Aktiva is a legally valid source document. An e-invoice received via Finbite is arguably better evidence than a paper invoice — it has a digital transmission record and a verified XML structure.
| Document Type | Digital Method | Time Required | Why This Works Legally |
|---|---|---|---|
| Supplier PDF invoice (email) | Forward email to accounting address as-is | 5 seconds | Digital original — email timestamp = receipt date; PDF is primary document |
| Supplier paper invoice (postal) | Photograph or scan; email to accounting address | 30 seconds | Raamatupidamise seadus §6 permits digital copies; paper original may be discarded after digitisation |
| Till receipt / kassatšekk | Photograph immediately with phone; email with item description | 30 seconds | Thermal paper receipts fade — digital copy taken same day is the usable record; EMTA accepts photo copies |
| Fuel receipt | Photograph at pump; email with vehicle registration number | 30 seconds | Business fuel deductibility requires vehicle ID + receipt; photo copy legally acceptable |
| E-invoice (e-arve XML) | Received directly into Merit Aktiva via Finbite/Telema network | 0 — automatic | XML e-invoice is the highest-quality digital document; no re-entry; no interpretation needed |
| Bank statement | LHV Connect API auto-import; or CSV download from SEB/Coop | 0 (LHV) / 2 min (CSV) | Bank data is digital by nature; API feed is most reliable; CSV is fallback |
| Contract (for accrual support) | Email PDF; upload to shared Google Drive folder | 1 minute | Contracts support accruals and deferred income entries; digital copy acceptable |
Setting Up Your Document Forwarding System
The simplest online document capture setup for a small OÜ uses three elements: an accounting email address for invoice forwarding, a shared cloud folder for bulk uploads, and the bank API feed for bank data. Once set up, the daily discipline is: forward every supplier invoice email as it arrives, photograph every physical receipt the same day, and the bank feed handles itself.
We provide a dedicated accounting@ email address. Forward every supplier invoice and receipt email directly. Email timestamp becomes the document receipt date.
Google Drive or Dropbox folder shared between you and the bookkeeper. For bulk monthly uploads — bank statements, payroll documents, contracts. Organised by year/month.
One-time setup. LHV business account → LHV portal → Connect API → Grant Merit Aktiva access. All transactions auto-imported daily thereafter. No manual step.
Photograph every physical receipt immediately — the same day. Never accumulate paper. Thermal receipts fade within weeks. A crisp photo is a better record than a faded original.
Ask Estonian B2B suppliers to connect via Finbite or Telema. Once connected, their invoices arrive directly in Merit Aktiva — zero manual work on your side.
Section 3 — Real-Time Access to Your Books
What you can see in Merit Aktiva at any time — without waiting for a report
Merit Aktiva Client Portal
With online bookkeeping through Merit Aktiva, you have read-only access to your own general ledger at all times. You do not need to wait for a monthly report to check your financial position — you can log in, see every posted transaction, and view your current account balances. This real-time visibility is one of the key practical advantages of cloud bookkeeping over traditional paper-based or email-report-based accounting.
| Portal Feature | What You Can See | Why It Is Useful |
|---|---|---|
| Real-time general ledger | All posted transactions for the current and prior periods; account balances updated as bookkeeper posts | Check whether last week’s large invoice has been posted; verify bank balance matches expectations |
| Issued invoices | All sales invoices created in Merit Aktiva — status (draft, sent, paid) | Confirm invoice was sent; check if payment received; identify overdue invoices |
| Purchase ledger | All purchase invoices received and posted — supplier, amount, due date, payment status | Track what is owed to suppliers; identify unpaid invoices approaching due date |
| Trial balance (live) | Running trial balance showing all account balances at today’s date | Instant financial position check without waiting for month-end report |
| Payroll summaries | If payroll is handled: salary slips, social tax breakdowns, net payment amounts per employee | Check your own salary slip; confirm payroll costs for the month |
| VAT ledger | Output and input VAT totals by period — data that feeds into KMD | See your VAT position before KMD is filed; flag any unexpected amounts |
Understanding Your Trial Balance
The trial balance (bilanss) is the core output of bookkeeping — a list of every account in your general ledger with its debit and credit totals and closing balance. A balanced trial balance (total debits = total credits) confirms that every posting was correctly entered as a double-entry. Reviewing it does not require accounting expertise — you mainly want to check that the account balances look reasonable, that there are no unexpectedly large negative balances, and that the bank balance matches what you see in your online banking.
| Trial Balance Account Group | What a Normal Balance Looks Like | What to Check |
|---|---|---|
| Bank accounts (1000) | Positive balance matching actual bank balance | Does this match your LHV / Wise balance? If not, there is an unreconciled item. |
| Trade receivables (1020) | Sum of all unpaid sales invoices | Are there old outstanding invoices here? Any paid but not cleared from the ledger? |
| Trade payables (2000) | Sum of all unpaid purchase invoices | Any invoices paid but not showing as paid in the ledger? |
| Revenue accounts (4000–4100) | Cumulative revenue for the year | Does the total match your expected turnover? Any large unusual entries? |
| Staff costs (6000) | Gross salaries + social tax for the year | Does monthly cost look right vs your headcount and salary levels? |
| Share capital (3000) | €2,500 (or higher if increased) | Should not change unless shares were issued — flag if it has changed unexpectedly |
| VAT payable (2100) | Positive = you owe VAT to EMTA; Negative = refund due | Does this match what you expect to pay on the 20th? |

| Signing Method | Device Required | Best For | Setup Required |
|---|---|---|---|
| e-ID card + card reader | Computer + USB card reader + DigiDoc4 desktop app | Desktop users; most reliable for complex multi-signature documents | Install DigiDoc4; purchase USB card reader (€10–25); insert e-ID card to sign |
| Mobile ID | Estonian phone number; smartphone | Mobile users; quick signing on the go | Register Mobile ID via your Estonian mobile operator (Tele2, Elisa, Telia); activate in the provider portal |
| Smart-ID | Smartphone (iOS or Android) | Most convenient; no physical hardware needed | Download Smart-ID app; verify identity at service point or online; activate account |
| Foreign digital ID (some countries) | Country-specific ID card + reader | Non-Estonian residents using their home country digital ID | Estonia’s äriregister accepts some EU digital IDs — check compatibility for your country |
