Integrations — GreyCube Technologies

Integrations

Connect ERPNext to the tools you already run.

Payments, marketplaces, messaging, logistics and tax portals — wired into one system of record. Native Frappe connectors where they exist, clean custom builds where they don't.

Upgrade-safe buildsNo core edits — survives every version bump
Bidirectional & secureOAuth2, webhooks and audited two-way sync

150+ integrations shipped

Across payments, e-commerce, logistics, messaging and tax across 15+ countries.

Native + custom

Frappe-native connectors first; bespoke API builds only where they're actually needed.

One source of truth

Data flows back into ERPNext — not into disconnected spreadsheets and silos.

Support that stays

SLA-backed monitoring, alerting and fixes after every integration goes live.

How we work

How an integration ships

A structured, upgrade-safe path from first call to a connection you can rely on in production.

01

Discovery & mapping

We audit both systems — fields, edge cases, data volumes and who owns which record.

02

Solution design

Sync direction, triggers, authentication and failure handling, designed to survive upgrades.

03

Build & QA

Built on Frappe APIs and webhooks, tested on staging against real data before go-live.

04

Go-live & monitoring

Clean cutover, reconciliation and SLA-backed alerting so breaks get caught early.

Under the hood

Built the right way

Standard, documented mechanisms — never hacks against the core that break on the next update.

REST APIsBidirectional, versioned
Frappe webhooksEvent-driven, real time
