Custom CRM development in Sofia
A CRM system built around your sales process: customers, deals, quotes, tasks and conversation history.
We build CRM systems around the way your team sells — by phone, email, Viber or in meetings. Customers, deals, quotes and conversations are all in one place, while tasks show who needs to do what. That is how Saitami ERP works too — our system with CRM, a built-in phone and PDF quotes.
We work from Sofia with clients across Bulgaria: remotely, and on site when the project requires it.

Questions and answers
Custom CRM development in Sofia: how much does it cost?
Custom CRM development in Sofia: €3,000-€29,300, typically around €8,600. The exact price is included in the written proposal.
Custom CRM 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 and data?
Yours. The code and customer database are delivered with the project.
Custom CRM 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 CRM system to our phone, email and website?
Yes. Saitami ERP has a built-in SIP phone, while the NAK website form creates an enquiry in the customer’s CRM system. The “Contact Center” demo brings email, chat, Viber and WhatsApp together in one inbox.
Off-the-shelf CRM or custom CRM?
An off-the-shelf CRM is a good choice if your process is standard. A custom CRM is for cases where you have your own stages, documents or need to connect it to your systems.
Can you migrate customers from Excel?
Yes — from Excel, Google Sheets or an old CRM system, as long as the data can be exported.
