Accounting software in Lithuania: an overview and how to choose

Accounting software commonly used and widely known in Lithuania includes Rivilė (GAMA and ERP), Site.pro (formerly B1.lt), Centas, Finvalda, Agnum and Debetas. They differ in where they run (on your computer or in the cloud), which modules are included and whether they can exchange data with an online shop or CRM. When choosing, the key checks are how the software prepares data for the Lithuanian tax authority, the VMI (i.SAF, i.VAZ, SAF-T), how many people will use it, whether you need stock management and whether there is an API for integrations.

This is not a ranking. The table summarises what the vendors themselves say about their software (as of October 2026), followed by the criteria worth using to choose.

Which accounting software is used in Lithuania?

Below are programs developed or distributed by Lithuanian vendors that have official websites. We do not list prices: they depend on modules and the number of users, so check the vendor’s website for current pricing.

“Ask the vendor” does not mean the feature is missing, only that the vendor does not describe it publicly. In that case, ask for documentation or a demo before you decide.

About B1.lt. The b1.lt address now redirects to site.pro, and the vendor states that the B1.lt accounting software is now called Site.pro. It is the same cloud product, and both names are still in use.

How does cloud accounting software differ from desktop software?

Cloud software runs on the vendor’s servers and opens in a browser, while desktop software is installed on your computer or an office server. Some vendors offer both.

Neither option is better in itself. If a company has its own server, a lot of warehouse activity and an IT specialist, installed software can work well. If the team works from different places and the accountant is external, the cloud is usually simpler.

How to choose accounting software

Decide first what the software needs to do in your company, and only then compare names. Below are the criteria worth discussing with your accountant and the vendor.

1. VMI reporting: i.SAF, i.VAZ and SAF-T

Your accounting software should help you meet tax obligations without retyping data:

• i.SAF is the VMI subsystem for VAT invoice registers. Data is submitted as an XML file, through a web service or entered on the portal (VMI).
• i.VAZ covers waybill data for goods in transit. If you ship goods, check whether the software prepares this data and how it is sent to the VMI (VMI).
• SAF-T is a standard audit file of accounting data exported from the company’s accounting system (VMI). It cannot be prepared by hand, so the software must be able to generate it.
• Invoices to the public sector. If you sell to state or municipal bodies, invoices to them are submitted through the Ministry of Finance’s SABIS system (Ministry of Finance). Ask whether the software helps issue such invoices without double entry.

Ask the vendor to show exactly how this works in practice.

2. Number of users and access

Count who will work in the software: the accountant, the director, sales managers, warehouse staff. Licences are often priced per user or per module, so this directly affects the cost. If your bookkeeping is outsourced, ask which software the accounting firm uses — sometimes it is easier to fit in with your accountant.

3. Stock, tills and manufacturing

A trading company needs to know whether the software tracks stock across several warehouses, connects to tills and scales, and supports order picking with a scanner. A manufacturer needs production accounting and cost calculation. A service business often only needs invoices, receivables and payroll.

4. API and integrations

If you run an online shop, a CRM or an order system, check how the software exchanges data:

• API — other systems can send orders and receive stock levels automatically;
• web service or module — similar, but often sold as a separate licence;
• file import and export — works almost everywhere, but someone has to do it.

“Integrations” on a vendor’s website does not mean there is a ready-made solution for your platform. Ask for the API documentation and whether API use costs extra.

5. Data migration and export

If you are switching software, find out how customers, product records, stock levels and debts will be migrated. Also check that you can export data from the new software to Excel or CSV — you will need this for reports and in case you ever switch again.

Questions to ask the vendor before you buy

1. How does the software prepare and submit i.SAF, i.VAZ and SAF-T data?
2. How much does an extra user or an extra module cost?
3. Is there an API or a web service, and where is the documentation?
4. How is data migrated from our current software?
5. Who makes backups, and how quickly can data be restored?

When do you need an integration with an online shop or CRM?

You need an integration when the same data is entered by hand into two systems. Typical signs:

• the accountant re-enters every online shop order in the accounting software;
• stock levels in the shop do not match the warehouse, so you sell items you no longer have;
• prices and new products appear in the accounting software first and are then copied to the shop separately;
• sales managers cannot see in the CRM whether a customer has paid an invoice.

With an integration, orders and invoices flow into your accounts automatically, while products, prices and stock levels flow to the shop. We connect via the software’s API, web service or data import — where your software allows it. A ready-made module or configuration costs from €490; a custom integration is quoted separately. More on accounting software integration, Rivilė integration and B1.lt (Site.pro) integration.

If you only get a few orders a week, an integration rarely pays for itself: importing sales from a file once a month is usually enough.

When is custom accounting or reporting software worth it?

Custom software does not replace your accounting package — it complements it where standard reports fall short. It is worth considering when:

• the director waits every month for reports that someone compiles from several Excel files and an accounting export;
• you need to calculate project profitability, working hours or commissions by your own rules;
• your data sits in several systems and none of them shows the full picture.

Such a web application pulls data from your accounting software’s export or API and produces reports in one click. Price: from €1,200; more on custom reporting software.

How can we help?

You buy the accounting software licence from the vendor or its partner; the Saitai.lt team connects the software you have chosen to your online shop, CRM or other systems and builds additional reports.

• Accounting software integration — orders, invoices, products and stock between your shop and your accounts.
• Custom reporting software — when you need reports your standard software cannot produce.
• What is a CRM — if you are deciding where to manage customers and sales.
• Document recognition – when purchase invoices should reach your accounts automatically rather than by hand.
• Report automation – when the same monthly reports are pulled together from several programs.
