What We Customise

Four levels of ERPNext customisation — all upgrade-safe.

Every customisation is built using Frappe's standard tools. Nothing is hard-coded into the core, so your ERPNext upgrades smoothly even after years of customisation.

Custom Fields, Forms & Print Formats

The most common customisations — adding fields ERPNext doesn't have by default, changing form layouts, and designing print formats that match your existing invoices, challans and purchase orders.

Custom fields on any document — Item, Customer, Sales Order, Work Order
Form layout changes — hide irrelevant fields, reorder sections
GST invoice print format — letterhead, logo, HSN, IRN QR code
Purchase Order and Delivery Challan formats
Branded Salary Slip format

From ₹15,000

Workflow Automation & Custom DocTypes

When your process doesn't fit the standard ERPNext flow — multi-level approval workflows, custom modules for processes ERPNext doesn't have natively, automated alerts and document routing.

Multi-level Purchase Order approval — manager, director, MD
Custom Inspection Checklist DocType for quality team
Automated WhatsApp alerts on document submit or status change
Custom pricing rule logic — complex discount structures
Custom dashboard tiles and workspace shortcuts

From ₹35,000

API Integrations

Connect ERPNext to your existing equipment and third-party systems — weighbridges, barcode scanners, biometric devices, payment gateways and eCommerce platforms, built as a maintainable Frappe app.

Weighbridge — auto-fill net/tare weight in Stock Entry or GRN
Barcode / QR scanner — item lookup in POS, GRN, Delivery Note
Razorpay — payment link generation from Sales Invoice
Shopify / WooCommerce — orders sync to Sales Order
Biometric attendance — punch-in/out sync to HRMS

From ₹50,000

Custom Frappe Apps

When your business needs a full custom module — its own DocTypes, reports, portal pages and automation — PS Digitise builds it as a standalone Frappe app on top of ERPNext.

Contractor / Job Work management module
Vehicle dispatch and fleet tracking module
Customer complaint and NCR management module
Dealer / distributor portal with custom ordering flow
Production schedule board with real-time Work Order status

How We Work

From requirement to live customisation — fixed price.

Every customisation project follows the same structured process. Scope and price agreed in writing before any development starts.

Discovery Call

30-minute call. You explain exactly what ERPNext doesn't do that you need. We ask questions to understand the full scope — inputs, outputs, edge cases and users involved.

Written Scope & Quote

Fixed-price written quote within 48 hours — exact scope, exact price, exact timeline. No hourly billing, no scope creep charges for agreed features.

Build & Test

Customisation built on a staging site first — you test it with real scenarios before it goes live. All edge cases covered before deployment to production.

Deploy & Train

Deployed to your live ERPNext site. Brief training for affected users. Documentation provided. 30 days support included for any issues post-deployment.

Frequently Asked Questions

Questions about ERPNext customisation.

Will customisations break when ERPNext is upgraded? +

No — if done correctly. PS Digitise uses only Frappe's standard customisation tools: Custom Fields, Client Scripts, Server Scripts and Custom DocTypes. We never modify ERPNext's core Python or JavaScript files. This means upgrades from v15 to v16 don't break your customisations. Before any major upgrade, we test on a staging site first.

How much does ERPNext customisation cost? +

Depends entirely on scope. Simple custom fields and print formats from ₹15,000. Workflow automation and custom DocTypes from ₹35,000. API integrations from ₹50,000. Complex custom Frappe apps on custom quote. PS Digitise provides a written fixed-price quote within 48 hours of a discovery call — you know the exact cost before any work starts.

Can ERPNext connect to our weighbridge machine? +

Yes. PS Digitise has built weighbridge integrations for manufacturing and agro processing clients — auto-filling net weight, tare weight and gross weight in Stock Entry, GRN and Delivery Note directly from the weighbridge display. Supports RS-232 serial and TCP/IP network protocols. No manual weight entry, no transcription errors.

How long does customisation take? +

Custom fields and print formats: 1–3 days. Workflow automation and custom DocTypes: 3–7 days. API integrations: 1–3 weeks depending on the third-party system's API documentation and reliability. Custom Frappe apps: 4–12 weeks. All timelines confirmed in the written quote before work starts.

Can you customise ERPNext we implemented with another partner? +

Yes. PS Digitise takes on ERPNext customisation projects for systems implemented by other partners. We start with a system review — understanding what's already been customised, how it's structured and what the impact of new changes will be. All our work is documented and handed over clearly.
