FAQ

Common questions

What is the Frappe Framework?

Frappe is an open-source, Python-based full-stack web framework — the foundation on which ERPNext is built. It provides a metadata-driven application development platform where you define data models (DocTypes), business logic (Python), and UI (JavaScript) in a structured, maintainable way. Frappe apps can run standalone or alongside ERPNext.

How long does a custom Frappe app take to develop?

A simple Frappe app (5–10 DocTypes, basic reports, standard Frappe UI) takes 4–8 weeks. A complex enterprise app with custom UI, advanced workflows, and external integrations may take 3–6 months. We provide fixed-price quotes for well-defined scope.

Can you customise ERPNext without breaking future upgrades?

Yes. We follow Frappe's customisation architecture — Custom Fields, Custom Scripts, Server Scripts, and custom apps — rather than modifying ERPNext core files. This keeps your system upgradeable and your customisations separated from the standard product.

Do you provide ongoing Frappe maintenance after delivery?

Yes. We offer post-delivery support contracts covering bug fixes, minor enhancements, Frappe version upgrades, and security patches. For clients on our managed cloud, we handle all infrastructure and application maintenance.
