Built with
We didn’t build all of this ourselves
Fretso stands on 21 open-source projects and services. Some of them represent decades of work by people we have never met, given away for free. Naming them is the least we can do, and it tells you exactly what you would be running.
The platform
What Fretso Pet ERP itself runs on.
- 01
Frappe Framework
The full-stack Python framework underneath the product. Document model, permissions, background jobs, REST API.

Who builds it
Fretso is built by TechNuventra
TechNuventra LLP is a technology consulting and custom software firm working across Pune, Bengaluru, Indore, Kolkata. They advise on strategy, build bespoke software, handle implementation and run managed services, mostly for industrial clients in oil and gas, mining, metals, manufacturing, logistics and energy.
Fretso came out of that practice: the same senior team, pointed at pet care instead of a refinery. It is why the software has real accounting underneath rather than an invoice screen, and why the guardrails are in the logic instead of the training manual.

Photography
And the people who took the pictures
Pexels doesn’t require attribution. Crediting the photographer costs nothing, so here they are.
