Quantbit's Developer SDK provides a documented REST API layer built on top of ERPNext's native Frappe API, pre-built authentication patterns in OAuth 2.0 and API key formats, a webhook infrastructure for event-driven integrations, and a dedicated sandbox ERPNext environment for development and testing. The SDK abstracts the complexity of ERPNext's internal document model so integration partners can build faster without needing deep Frappe framework expertise. Partner support is available during development for architecture questions and API troubleshooting.
To build a certified ERPNext connector through Quantbit's partner programme, an ISV needs access to ERPNext's REST API documentation, a sandbox environment with representative data for testing, and understanding of ERPNext's core document model. Quantbit's Developer SDK provides all of this alongside pre-built patterns for common integration scenarios — inbound webhook handling, outbound data push, scheduled batch sync, and bidirectional field mapping. Partners also receive a technical review before certification to ensure the integration follows Quantbit's data quality and security standards.
ISVs, system integrators, and technology partners — if your customers use ERPNext and your software, they want the two to work together. Quantbit's Developer SDK gives you the infrastructure, documentation, and sandbox environment to build it right and certify it fast.
Building on ERPNext's Frappe API directly is powerful but complex. The Quantbit Developer SDK gives you the building blocks to go from idea to certified integration faster.
A documented, versioned REST API on top of ERPNext's native Frappe API — with consistent response formats, standardized error codes, and predictable endpoint patterns across all ERPNext doctypes.
Event-driven integrations react to ERPNext events in real time — invoice submission, payment entry, work order completion, stock movement. Our webhook layer handles delivery, retry, and signature verification.
Multiple authentication methods to fit how your integration architecture works — API keys for server-to-server, OAuth 2.0 for user-authorized integrations, and token refresh for long-running processes.
A full ERPNext sandbox instance with representative test data — customers, items, invoices, and transactions — so you can develop and test your integration without touching production data or bothering a live customer.
Practical documentation written for developers who have not worked with ERPNext before — not just API reference, but architecture guides, common integration patterns, and worked examples.
A structured review process that validates your integration against Quantbit's quality and security standards before it is listed in the integration directory and marketed to shared customers.
Whether you are an individual developer building your first ERPNext connector or an established ISV looking for co-selling support, there is a partner tier that fits your stage.
For: Freelancers, agencies, and early-stage ISVs building their first ERPNext connector
For: ISVs with an established product that serves 10+ ERPNext customers or has a clear mutual customer base
For: Established software companies with significant customer overlap and commitment to joint go-to-market
The decision to build an ERPNext connector is almost always driven by the same thing — a customer asking for it. These are the stories of what happened when partners decided to invest in the integration rather than treating it as a one-off custom job.
A Pune-based HR and payroll SaaS company had been receiving the same request from three different customers independently over eighteen months: "Can your payroll system talk to ERPNext?" Each time, the customer wanted payroll journal entries to post automatically to ERPNext — their company's books were in ERPNext and the manual process of transferring payroll figures was error-prone and time-consuming. The product team had put the integration on the roadmap three times and deprioritized it each time because building a one-off ERPNext integration seemed like too much effort for uncertain revenue. When the fourth customer asked and threatened to switch to a competitor that had an ERPNext connector, the product head decided to invest. Using Quantbit's Developer SDK, they built the integration in six weeks — monthly payroll summary, department-wise cost allocation, and salary component mapping to ERPNext accounts. Within three months of publishing the integration, they had signed two new ERPNext customers who had chosen them specifically because of the connector. The integration had paid for itself before the end of the quarter.
A Mumbai-based Transport Management System (TMS) company was serving medium-sized logistics businesses across India. Several of their clients were also ERPNext users — and the disconnect between ERPNext sales orders and the TMS was creating daily friction. Someone had to manually transfer delivery information from ERPNext to the TMS, and tracking updates from the TMS never made it back to ERPNext. The TMS company built a certified integration using Quantbit's SDK: when a delivery note is created in ERPNext, a shipment is automatically created in the TMS. When the TMS updates the delivery status, it pushes back to the Delivery Note in ERPNext. When the shipment is delivered, the proof of delivery links to the ERPNext document. The integration took eight weeks to build and certify. Since listing on Quantbit's partner directory, the TMS company has been introduced to eleven of Quantbit's logistics and trading customers — five of whom have become TMS customers as a direct result of the ERPNext integration partnership.
A quality management SaaS company in Nashik was selling their non-conformance and CAPA (Corrective and Preventive Action) management software to manufacturers. The objection they kept hearing in manufacturing companies that ran ERPNext was: "Why do we need separate quality software when ERPNext has quality modules?" It was a difficult objection to counter — ERPNext's quality features are reasonable, even if the QMS company's product was significantly more capable for ISO 9001 and IATF 16949 compliance. When they built a certified ERPNext integration — quality inspections in ERPNext automatically create non-conformance reports in their QMS, and CAPA closures in the QMS update the ERPNext quality record — the objection disappeared. Instead of competing with ERPNext, their software now extended it. The demo changed completely: rather than showing a standalone system, they showed ERPNext and their QMS working together. Win rate against the "let's just use ERPNext quality" objection went from 20% to 65%.
A retail analytics company in Bengaluru was selling sell-through analysis and demand forecasting tools to consumer goods brands and retail chains. When they surveyed their 40 existing customers to understand what systems they used for inventory and sales data, they discovered that 18 of them were running ERPNext — and in every case, getting data from ERPNext into the analytics platform was a manual monthly exercise. Someone exported CSVs from ERPNext, cleaned them up, and uploaded them to the analytics platform. The analytics company built an ERPNext integration that pulled daily sales, inventory, and purchasing data automatically. For the 18 customers already on ERPNext, it was an immediate upgrade — daily analysis instead of monthly. For prospects who were ERPNext users, it was a strong differentiator. And Quantbit's partnership introduced them to ten additional ERPNext customers they had not previously reached. The integration went from a gap in their product to a genuine competitive advantage in their target market.
