How much does invoice automation cost in Bulgaria? Real 2026 prices

Invoice automation in Bulgaria ranges from about 900 euro for a starter solution to 4500 euro and up for multi-company processing with integration. The difference comes from document volume, the number of suppliers, and how it connects to the accounting software. Here we break down where the money goes and how to judge whether it is worth it for your case.

What the price depends on

Two firms with the same number of clients can get different quotes, because price is set by complexity, not by the company logo. The main factors are:

• Invoices per month. Under 150 documents automation rarely pays back quickly; over 500 the gain is obvious.
• The number of different suppliers and layouts the model has to recognise.
• Accounting software and integration method — an import file for Microinvest is cheaper than a programmatic connection.
• The need to validate against the tax register by company ID and VAT number.
• Processing in the cloud or on your own server (on-prem costs more, but some firms require it).

Real price tiers

Here are the ranges we see on the market in 2026 for implementation (one-off price):

Starter: 900 – 1500 euro

One entry point (one inbox or one folder), one import format, up to around 20 regular suppliers. Suited to a small firm or a company that wants to test the approach without a big commitment.

Standard: 2000 – 3500 euro

Several clients or folders, validation against the tax register, a direct connection to Microinvest Delta Pro or Ajur, handling of credit notes and pro-formas. This is the level most firms stay at.

Custom: 3500 – 4500+ euro

Multi-company processing, special VAT regimes, processing on your own server, and an audit trail for every document. The price depends on scope and is fixed after a written analysis.

Monthly costs to expect

Beyond the one-off implementation there are two small running costs an honest provider shows upfront:

• Per-document processing — the OCR and language-model cost is on the order of cents per invoice, usually under 10 euro a month at typical volume.
• Support — between 50 and 150 euro a month for monitoring, fixes when suppliers change, and a response when something breaks.

When the investment pays back

The maths depends entirely on volume. A firm with 600 invoices a month spends about 20 hours on manual entry, nearly 300 euro of labour at 15 euro an hour. At an implementation of 2500 euro, the saved time returns the money in about eight months, and after that it saves 250 euro a month net.

At 1500 invoices a month the payback drops under five months. The higher the volume, the faster the investment returns.

When it is not worth it

Under 150 invoices a month and with many non-standard documents, automation may not pay back soon. In those cases we say so directly and propose a smaller step instead of a full build. We do not sell a solution that will not return its cost.

Frequently asked questions

Is the Microinvest integration included in the price?

Yes. At the standard and custom tiers the connection to Microinvest or Ajur is part of the build. At the starter tier it is usually an import file you load yourself, with a direct connection as an upgrade.

Is it charged per document or fixed?

The build is a fixed one-off price. Running, you pay only the small per-document processing cost and monthly support. There is no per-invoice fee on top of that.

Why are some quotes over 10,000 euro?

Usually because of multi-company processing, complex VAT regimes, or a requirement to run on your own server. For a standard firm such a price is rarely justified.

Are there hidden costs?

Not with us. The breakdown is three items: a one-off build, a per-document processing cost, and monthly support. Everything is fixed in writing before we start.
