Accounting software
Saitami builds the system that saves an accounting firm hours every month: Account-X collects documents from clients through a portal, reads invoices with AI, reconciles the bank, and reminds you of NRA deadlines. A system like this costs 3 000-29 300 € (based on 98 of our quotes as of 14 August 2026). The accounting itself (chart of accounts, VAT ledgers, fixed assets, payroll, closing) remains in the software the firm already uses: Plus Minus, Ajur, Microinvest Delta Pro or Biznes Navigator.
What it includes
- Document portal
The client uploads invoices, cash reports and bank statements in one place instead of sending them by email and Viber.
- AI recognition
The system reads the invoice and suggests an accounting entry with a confidence percentage; the accountant only confirms it.
- Bank reconciliation
Payments from the statement are matched to invoices, while unrecognized ones remain for review.
- NRA deadlines
VAT, social security, Intrastat and year-end closing by client, with a reminder before each deadline.
- Accountant tasks
Which accountant manages which company, what documents are still awaited and what is ready.
- Firm invoices
The monthly fee agreed with each client, invoiced all at once, and unpaid invoices on one screen.
How the process works
- 1The client uploads the month's documents to the portal, and the system reads them and suggests an accounting entry.
- 2The accountant confirms it, matches the bank transactions and transfers the data to the accounting software.
- 3Before the NRA deadline, the system reminds you which client is still not ready, and the fees are generated all at once.

In short: two systems, not one
The company's accounting is handled in accounting software (Plus Minus, Ajur, Microinvest Delta Pro, Biznes Navigator), which is updated whenever the law changes. Saitami does not replace it, but works with it: documents, invoices and bank data reach the accountant organised and ready, without retyping.
If you are an accounting firm, you also have a second problem that accounting software does not solve: documents from 50 or 150 clients arrive by email, Viber and in bags, while NRA deadlines are tracked in a spreadsheet. That is why we built Account-X, the firm’s system around its accounting software.
Ready-made accounting software
These are the programs used by most accountants in Bulgaria. The price is published only for Microinvest; for the others, it is provided by the manufacturer or reseller.
| Program | Price as published | Source |
|---|---|---|
| Microinvest Delta Pro | 298 EUR excluding VAT for one workstation, with TRZ and LS Pro; Account package 499 EUR and Complex package 699 EUR | microinvest.net, 17.10.2026 |
| Plus Minus | we could not find a published price; provided by the manufacturer | plusminus.bg |
| Ajur (B-Soft) | we could not find a published price; accounting, public-sector accounting, payroll and warehouse management | ajur.bg |
| Business Navigator | we could not find a published price | bn.bg |
Choose the program your accountant already knows: that saves more than the price difference. For issuing invoices without accounting, see the invoicing software page.
What accounting software must be able to do in 2026
Whichever program you choose, check these things with the manufacturer:
- The euro: from 1 January 2026, accounting is kept in euros, while old balances in leva are converted at a rate of 1.95583.
- Purchase and sales ledgers and the VAT return by the 14th of the following month, in the NRA format.
- SAF-T: the standard audit file that the NRA is introducing in stages, starting with large enterprises.
- Electronic invoices: the draft amendments to the VAT Act provide for mandatory structured electronic invoices between companies from 2028; the software must be able to receive and issue them.
- Bank connection: import statements so payments do not have to be entered manually.
- Client access, or at least export, when the accounting firm manages many companies.
Account-X: the accounting firm system
Account-X brings the accounting firm and all its clients together on one screen. The manager can see clients, contracts and fees, which accountant manages which company, and what is coming up. Each client has a portal where they upload their documents for the month, see what is missing and download their reports.
Documents are read with AI: the system recognises the invoice and suggests an accounting entry with a confidence percentage, instead of making the accountant retype it. Bank statements are matched to invoices, while VAT, social security and year-end closing deadlines are tracked and reminders are sent for each client. The demo is open and shows all of this with sample data.
When does an accounting firm system pay for itself?
A firm with 10 or 20 clients can manage with email and a spreadsheet and should not pay 3 000-29 300 €. The numbers work for a firm with several accountants and more than 50 clients: if each client takes an hour a month to chase and re-enter documents, that is more than 50 hours a month the system gives back. The system is paid for once, the code and data belong to the firm, and support costs 100-350 € per month, as needed.
What we have not done so far
Account-X is a demo with sample data; we do not yet have an accounting firm running a system built by us. We do not submit returns to the NRA: the system tracks deadlines and sends reminders. We have not connected the system directly to Plus Minus, Ajur or Microinvest; data is transferred by importing a file, and if your program offers another connection, we will check it before quoting a price.

The one your accountant knows. The most widely used in Bulgaria are Plus Minus, Ajur, Microinvest Delta Pro and Business Navigator. Microinvest Delta Pro has a published price: EUR 298 excluding VAT for one workstation.
No. We build Account-X, the accounting firm’s system around its accounting software: a portal for clients’ documents, AI recognition, bank reconciliation and NRA deadlines.
No. The system tracks VAT, social security and year-end closing deadlines for each client and sends reminders; filing remains in the accounting software and the NRA portal.
A custom system like Account-X costs €3,000-29,300 as a one-time fee, plus optional maintenance of €100-350 per month. It pays for itself at a firm with several accountants and more than 50 clients.
So far, we have not connected a system directly to them; the data is transferred by importing a file. If your software provides another integration method, we check it before giving you a price.
As of 1 January 2026, accounting is kept in euro, and balances in leva have been converted at the rate of 1.95583. Accounting software providers supplied conversion tools; ask yours which version to use.
