Frappe App Development
Custom Frappe apps / Full Stack apps, built to survive upgrades.
New apps on the Frappe Framework, and/or clean extensions to ERPNext — everything lives in its own app using hooks and fixtures, so nothing breaks when you update.
What we do
Four ways to make ERPNext fit your business
From a few no-code tweaks to a full custom app or a headless API backend — we pick the lightest approach that does the job and keeps every upgrade clean.
Custom app development
A brand-new app on the Frappe Framework for a workflow standard ERPNext doesn't cover — with its own data model, logic, screens and reports.
- New DocTypes & relationships modelled to your process
- Business logic in server-side Python controllers
- Reports, dashboards & print formats
- Its own portal pages and REST APIs
ERPNext customization & extension
Bend ERPNext to your business without touching core — custom fields, scripts, workflows and overrides, all packaged in a separate, upgrade-safe app.
- Custom fields & property setters
- Client scripts & server-side automation
- Approval workflows & notifications
- Doc events & method overrides via hooks
Site customization (no-code / low-code)
Quick changes made right inside Frappe Desk — no deployment, no separate app — for the tweaks that don't need a full build.
- In-app customizer for forms, fields & permissions
- Client Scripts for real-time UI behaviour
- Server Scripts for lightweight Python logic
Headless & API-driven apps
Use Frappe purely as a secure backend — data, permissions and automated REST APIs — with your own frontend on top.
- Frappe as a secure REST API backend
- VueJS, React frontends via token auth
- Backend on Frappe Cloud, frontend deployed anywhere
350+ apps & extensions
Shipped across manufacturing, trading, services and field operations.
No core edits
Every change lives in a versioned custom app — never in core files.
Upgrade-safe
Hooks, fixtures and patches keep you clean through version jumps.
One namespaced app
Everything we build sits in a single, clearly named app — never scattered across the core.
What goes in
The building blocks we work with
Everything a Frappe app is made of — used the way the framework intends, so it stays maintainable.
DocTypes & data model
The tables, links and child tables your workflow needs — normalised and indexed from the start.
Server-side logic
Validation, automation and calculations in Python controllers, running where the data lives.
Client scripts & forms
Dynamic form behaviour, field logic and UX tweaks that make data entry faster and safer.
Workflows & approvals
Multi-stage states with the right roles, transitions and notifications at each step.
Reports & dashboards
Query and script reports, number cards and charts that answer real business questions.
Print formats
Pixel-accurate invoices, labels and statements — built to render cleanly through wkhtmltopdf.
REST APIs & webhooks
Whitelisted endpoints and event hooks so other systems can read and write safely.
Portal & web pages
Customer and vendor self-service built on the Frappe website layer, tied to live data.
Roles & permissions
Role-based access, permission rules and field-level control mapped to your org.
How we keep it clean
Built so updates don't break you
The discipline that separates a customization you can live with from one that fights every upgrade.
A separate custom app
Never edit core or standard apps in place — your logic ships as its own installable app.
Hooks over hacks
Doc events, overrides and scheduled jobs wired through hooks.py — not
monkey-patches.
Fixtures for config
Custom fields, roles and settings travel with the app, so every site sets up identically.
Overlay, don't inject
We extend the UI in ways that survive upgrades, rather than fragile DOM patching that breaks.
Patches & migrations
Versioned data patches run on bench migrate, so schema and data move forward
safely.
Git, review & staging
Everything in version control, reviewed, and tested on staging before it reaches production.
How we work
How a build ships
From a workflow on a whiteboard to an installed app, with the upgrade path handled from day one.
Discovery & data model
We map the workflow and design the DocTypes, relationships and roles behind it.
Design & spec
Screens, states, permissions and reports agreed and signed off before we build.
Build & test
Coded in a custom app on Frappe conventions, tested on staging with real data.
Deploy & support
Migrate, apply fixtures, hand over the source — then upgrades and ongoing support.
Under the hood
The stack we build on
The framework and tooling behind every app — standard, documented and well-supported.
Your business is unique and doesn't fit standard ERPNext?
Tell us the workflow that doesn't fit — we'll tell you whether it's a customization or a full custom app, and scope it straight. No hard sell.
