Ask a Lithuanian founder how their accounting works and the answer is usually short: "I send everything to my accountant." Behind that sentence sits a monthly routine that is mostly people moving documents and typing numbers. This article lays that routine out step by step, so it is clear where the time goes — and which parts a system can take over.
Who keeps the books
Lithuanian law makes the company's manager responsible for organising the accounting, but the day-to-day work is done by an accountant — either an employee or a specialised firm, as accounting firms such as Audikom explain. Small companies rarely hire someone full-time: they outsource, and the accounting firm becomes the place where the company's paperwork ends up every month.
The monthly cycle
The company collects and sends its documents
Once a month the business hands over the previous month: purchase and sales invoices, bank statements, cash receipts and related papers, so the bookkeeper can register everything and prepare the reports for the tax and social-security authorities (immigration.lt).
The bookkeeper keys the documents into software
Each invoice becomes a booking: supplier, VAT number, amount, VAT rate, account. Bank lines are matched to invoices by hand or with the software's help.
Payroll and monthly declarations
Income tax and social-security reports calculated from salaries, and the VAT report, are due monthly; the profit-tax report and the annual financial statements are yearly (immigration.lt). VAT-registered companies also submit the i.SAF invoice register every month, by the 20th of the following month — even when there were no invoices (source).
Year-end
The accountant reconciles balances, assigns income and expenses to the right periods and prepares the financial statements filed with the Centre of Registers (Audikom).
The tools people use
The smallest businesses start with Excel or paper folders. A Lithuanian accounting firm that compares the options notes that in Excel many documents — debt reconciliation acts, VAT invoice registers, payslips — have to be filled in by hand, and recommends it only for a very small company with a handful of invoices a year (MB Apskaita). One Lithuanian accounting-training site describes the market roughly like this: small companies choose simple tools such as B1.lt or Centas, mid-sized ones mostly use Rivilė or Finvalda, and large ones use Dynamics NAV or SAP (Apskaitos mokykla, 2025).
Why so much stays manual
- Invoices arrive as PDFs and paper. A PDF invoice sent by email is fully legal in Lithuania. Structured e-invoicing is mandatory only towards public bodies (via SABIS); for business-to-business it is voluntary, and a B2B rule is only expected around 2028, with the design not finalised (VATupdate, Ezura). A PDF still has to be read by someone.
- Reading tools are add-ons. Services such as DokSkenas and įvesk.lt scan invoices and prepare import files for the accounting program — a separate step and a separate subscription.
- The tax authority sees every invoice. Because i.SAF data is checked against VAT returns, each invoice has to be captured completely and correctly, every month.
- You pay for the keying. Accounting firms quote from about €50 a month for small companies, and VAT registration typically adds €30–120 a month because of the extra registers and returns (apskaitos-paslaugos.lt, Kauno Buhalteriai).
What can change
The manual part is not the accountant's judgment. It is everything before it: getting the document, reading it, typing it, matching it to the bank, and turning the result into the monthly files. That is the part a system can carry.
With FiscFort, the business owner gets a dedicated web portal and Odoo of their own. Invoices and vendor bills are uploaded as PDFs, cash and card takings are typed in directly, and bank statements are uploaded in the bank's export format — the CAMT.053 format used by Lithuanian banks and Revolut. An AI model reads each document, the system matches it to the bank line, and the entry lands in Odoo for review. Staff hours and payroll follow Lithuanian rules, including the public holidays. From the booked data the system prepares the statutory files: GPM313, SAM, i.SAF, and the employee-event forms 1-SD, 2-SD, 12-SD and NP-SD2, plus a live view of what is due to VMI and Sodra this month with the payment codes.
What stays a human decision
The number-generation path has no AI in it: figures are calculated by fixed rules and checked against the booked data. Nothing is sent to the authorities automatically. The accountant reviews every filing and submits it, exactly as before — with hours of keying removed from the work that leads up to it.
