We build the systems we go on to run ourselves.
VertaStack is a software company in Plovdiv, founded in 2017. We work with retailers and distributors whose stock, orders and documents pass through more than one system.
How it started
In 2017 we took on a job that looked small on paper: the shop and the warehouse should show the same number. Between them sat an ERP with no interface, a supplier sending files in four formats, and three people retyping by hand.
The same problem turned up at the next client, and the one after that. What was written once became a product, then four.
Today we sell the finished products on subscription and build systems to order when the case does not fit them. The hosting and the support stay with us.

What we work with
How we work. From discovery to support.
The same process across 50+ projects since 2017. Every stage ends with a result and a clear next step.
Discovery
We go through your processes, systems and constraints, then put the scope, the timeline and the measure of success in writing.
Design
We show how it will look and how it will work: the screens, the steps, who sees what. Nothing gets built until you have approved it.
Development
We build on technology another team can still maintain years from now. Every week we show the working part of the system, not slides about it.
Testing
We test on the browsers and devices your customers arrive with, and at load above the usual peak. Before every release we check performance and security.
Launch & Ongoing
We launch the system and take on hosting, monitoring, updates and backups.
The first step is a short conversation.
We reply within 24 hours. A detailed brief is not needed beforehand.
