Sofia, Bulgaria
Custom ERP development in Sofia
An ERP system built around your processes: inventory, sales, invoices, reports, and roles in one web-based system.
We build ERP systems around the way your company already works—who enters data, who approves it and what gets invoiced. The system runs in a browser and, when needed, on the phones of your field team. Before you receive a proposal, you see a demo with your modules.
We work from Sofia with clients across Bulgaria: remotely, and on site when the project requires it.

What you get
- Built around your process
The modules, roles, and documents follow the way your company works, rather than a ready-made template.

Batches, expiry dates, barcodes and production recipes, just like in the Testen Dom demo.
- Invoices and payments
Automated invoicing and online payments through Stripe, as in LiftexPro.
- Field team
A mobile app for technicians with digital protocol signing, as in LiftexPro.
- Roles and reports
Everyone sees their part, while the manager sees reports in real time.

Questions and answers
Custom ERP development in Sofia: how much does it cost?
Custom ERP development in Sofia: €3,000-€29,300, typically around €8,600. The exact price is included in the written proposal.
Custom ERP development in Sofia: how long does it take?
It depends on the scope, which we set out in the proposal. For comparison, here are examples from our portfolio: Pelikan DTM: since April 2026, continuously developed, Elite Call Center: 6 months, LiftexPro: 8 months.
Who owns the code?
Yours. The code and data are handed over with the project, and you can continue development with another team.
Custom ERP development in Sofia: what happens after launch?
If you wish, we can maintain the project for €100-€350 per month. We specify what maintenance includes in the quote.
Can you connect the system to payments, phones, and documents?
Yes. LiftexPro accepts payments through Stripe, Saitami’s CRM system has a built-in SIP phone, and the Account-X demo recognizes documents with AI and matches bank payments.
Can I see a live system?
Yes. The portfolio includes live demo systems—an ERP for a security company, a manufacturing ERP, one for an accounting firm and one for taxi dispatching. After the initial conversation, we also build a demo with your modules.
Can you transfer data from Excel or our old software?
Yes, if the data can be exported to a file or through an API. We specify how we will transfer it in the proposal.
Off-the-shelf ERP or custom ERP?
An off-the-shelf system can be launched faster, but your processes must adapt to it. A custom ERP follows your process, and you own the code.
