What we customise

Every Layer of ERPNext, Customised Precisely

Quantbit's customisation work spans every layer of ERPNext — from the fields a user sees on screen to the logic that runs when they submit a document.

📝

Custom Fields & Forms

Add industry-specific fields, hide irrelevant ones, reorder layouts, add conditional visibility, and create linked child tables — all upgrade-safe.

🔄

Workflow & Approvals

Multi-level approvals, role-based state machines, email notifications, and escalation logic built within ERPNext's workflow engine.

📊

Custom Reports

Script reports, query reports, and dashboards that give your management team exactly the numbers they need — replacing external BI tools.

🖨️

Print Formats & Documents

Invoice layouts, delivery challans, purchase orders, and any document template — pixel-perfect to your brand and statutory requirements.

Client & Server Scripts

Business logic triggered on document events — auto-calculations, validations, field fetch, cross-document updates — in Python and JavaScript.

Integrations & APIs

Common questions

ERPNext Customisation — Answered

ERPNext is designed for customisation. Custom Fields, Forms, Client Scripts, Server Scripts, Workflow rules, Print Formats, and Custom Reports can all be added through the Customisation interface or as a separate Frappe app — without touching core code. Quantbit always follows upgrade-safe practices so your customisations survive version updates.
Yes. ERPNext supports Query Reports (SQL-based), Script Reports (Python-based), and Report Builder reports. Quantbit builds all three and also creates custom dashboards with real-time charts and KPI cards. We regularly build report suites that replace entire BI tools for clients, saving significant licensing cost.
ERPNext has a built-in Workflow module for states, transitions, and permission rules. For complex approvals, Quantbit combines ERPNext Workflows with Server Scripts triggered on document events and Email Alerts for notifications. We have built procurement, HR, and production authorisation chains entirely within ERPNext.
Yes — if done correctly. Customisations through the ERPNext Customisation interface are stored in the database and survive upgrades. Quantbit strictly follows upgrade-safe practices: no core file edits, all logic in Scripts or separate Frappe apps, and thorough post-upgrade testing every time.
Customisation uses built-in tools to extend existing DocTypes. A custom Frappe app creates entirely new DocTypes and business logic in a separate package. For most requirements, customisation is faster and sufficient. For complex industry-specific requirements — like our FoundryX or CFMSX products — a full Frappe app provides better architecture and independent versioning.

ERPNext almost fits — but not quite?
