About Cost-Effective Software

Cost-Effective Software is the software studio of Effective Software Solutions Ltd., a Bulgarian company based in Sofia. We build custom software and AI automation for small and mid-sized businesses - systems shaped around how a company already works, instead of forcing the company to work around an off-the-shelf tool.

What we do

Most of our clients come to us with the same picture: orders living in spreadsheets, quotes going out by phone, a CRM nobody opens, and no single source of truth. We replace that with one system - order hubs, quoting and document automation, AI agents for repetitive work, and integrations with the ERP and accounting software already in place. Engagements are project-based with a fixed scope, a fixed price agreed upfront, and visible progress within the first week.

We work across accounting, e-commerce, education, healthcare, hospitality, law, logistics, pharma and real estate, and we ship MVPs and AI-agent products for founders. Recent public work includes an internal order hub that replaced six spreadsheets and cut order turnaround from 1.5 days to 30 minutes, a national learning portal with over 1,000 courses, and automated e-commerce campaigns that lifted monthly sales by 22%.

How we work

Every engagement starts with a free 30-minute Profit Leak Consultation: we find the biggest bottleneck in your operations and put a yearly number on what it costs you. A deep-dive call (on site if needed) pins down exactly what the software must do, then you receive a concrete offer with fixed scope, price and timeline. In 2026 we have delivered 40+ projects with zero missed deadlines.
