We Have Built the Products That Prove the Expertise

Most Frappe development companies learn the framework on your project. Quantbit's team has shipped 10 production vertical products on Frappe — FoundryX, MachineX, CFMSX, PropX, WMSPro, FleetX, and more. That depth of real-world framework usage means fewer surprises, cleaner architecture, and faster delivery on your custom project.

DocType Design & Data Architecture

Well-designed DocTypes are the foundation of every Frappe application. Our team designs DocType schemas that are normalised, performant, and extensible — avoiding the technical debt that comes from rushing this stage.

Server-Side Python Logic

Complex business logic, background jobs, scheduled tasks, and document lifecycle hooks — written in clean, testable Python that integrates with Frappe's built-in scheduler and event system.

REST API & Third-Party Integration

Frappe's REST API is powerful — but integrating it securely with external systems requires understanding rate limiting, authentication patterns, data mapping, and error handling. We have built dozens of production integrations.

Common questions

Frappe Development — Answered

Frappe is a full-stack, open-source web application framework written in Python and JavaScript. It powers ERPNext and can be used to build any type of business application — CRM systems, industry-specific ERP modules, SaaS products, IoT dashboards, mobile backends, and more. Its meta-data driven architecture means business application development is 60–70% faster than traditional frameworks.
Frappe provides the infrastructure for business apps — database abstraction, permissions, REST API, forms, reports, workflows — out of the box. A module that takes 6 months in Django takes 4–6 weeks in Frappe. For organisations already on ERPNext, Frappe apps integrate natively. Quantbit has observed 60–70% faster delivery for business application types on Frappe vs other frameworks.
Yes. Quantbit builds REST API integrations between ERPNext and external systems including Shopify, WooCommerce, Amazon, payment gateways, banking systems, logistics APIs, HRMS platforms, IoT sensors, and third-party CRMs. We use Frappe's native webhook and API layer alongside custom middleware where required.
An ERPNext customisation modifies existing ERPNext forms, reports, or workflows using Client Scripts, Server Scripts, or Custom Fields. A Frappe app is a separate Python package that extends the framework with entirely new DocTypes, pages, APIs, or UI components. Frappe apps are independently versionable, more powerful, and distributable on the Frappe Marketplace. Quantbit builds both and recommends the right approach based on complexity and long-term maintainability.
A simple Frappe app with 3–5 new DocTypes and basic workflows takes 3–6 weeks. A complex multi-module app with integrations and custom reports takes 3–6 months. Quantbit follows an agile sprint model — you see working software every 2 weeks and can course-correct throughout.
Yes. Quantbit builds React Native and Flutter mobile apps integrated with Frappe's REST API. We have delivered mobile apps for warehouse barcode scanning, field service management, attendance capture, and production floor control — all syncing in real time with the ERPNext backend.
