Production-minded n8n community nodes for ERPNext and Frappe automation.
Built as a connected ERP ecosystem, not isolated node packages.

n8n2erpnext is an open-source ecosystem of n8n community nodes for ERPNext and Frappe. It helps teams automate real ERP operations such as accounting, procurement, sales, warehouse movement, inventory validation, and cross-module document integrity.

The project is designed for:

• ERPNext automation with n8n.
• Frappe REST API integrations.
• Self-hosted ERP operations.
• SME and mid-market business workflow automation.
• Retail, distribution, stock, buying, selling, accounting, HRMS, and ERP operations.
• AI-searchable ERPNext integration examples with production-style README documentation.

The core business modules are now validated as one connected ERP system:

Buying -> Stock -> Selling -> Accounting

The Stock validation suite includes two live-tested enterprise workflows that prove cross-module behavior end to end:

Standard Product Lifecycle
Supplier -> Purchase Receipt -> Inventory Increase -> Purchase Invoice
-> Customer Sale -> Sales Invoice update_stock=1 -> Inventory Decrease
-> Bin, Stock Ledger Entry, and Accounting verification

Exception / After-Sales Lifecycle
Sale -> Return Credit Note -> Warranty Warehouse -> Defective Warehouse
-> Repair / Virtual Workshop -> Disposal
-> Bin, Stock Ledger Entry, and Accounting verification

These workflows prove:

• Inventory can safely enter the business.
• Inventory can safely move through warehouses.
• Inventory can safely leave through sales.
• Return, warranty, defect, repair, and disposal flows are covered.
• Internal trade can move stock and accounting across two ERPNext companies.
• Purchase Invoice locks protect Purchase Receipt cancellation.
• Sales Invoice locks protect Delivery Note cancellation.
• Linked inter-company Purchase Invoice records protect Sales Invoice cancellation.
• Valid inter-company reversal works when the receiving Purchase Invoice is cancelled before the source Sales Invoice.
• Non-stock fee and rebate invoices do not create Stock Ledger Entry rows.
• Public webhook responses are allowlisted and checked for credential leaks.

Detailed coverage notes, tested ERPNext pain points, and live document references are maintained in docs/ecosystem-coverage.md.

Module	Package	npm	Scope	Status
Core	n8n-nodes-frappe-core	Foundation package	Generic Frappe API, shared credential pattern, core API behavior	In progress
HRMS	n8n-nodes-erpnext-hrms	npm	Employees, attendance, leave, payroll-adjacent workflows	Live
Accounting	n8n-nodes-erpnext-accounting	npm	Sales Invoice, Purchase Invoice, Payment Entry, Journal Entry, GL Entry	Live
Buying	n8n-nodes-erpnext-buying	npm	Supplier, RFQ, Supplier Quotation, Purchase Order, Purchase Receipt	Live
Selling	n8n-nodes-erpnext-selling	npm	Customer, Lead, Opportunity, Quotation, Sales Order	Live
Stock	n8n-nodes-erpnext-stock	npm	Item, Warehouse, Stock Entry, Delivery Note, Batch, Serial No, Bin, Stock Ledger Entry	Live

The active ecosystem has been tested against ERPNext/Frappe v16 behavior on a self-hosted n8n runtime with API v1 and API v2 document workflows.

Many ERPNext integrations stop at generic HTTP requests. n8n2erpnext goes further by packaging repeatable, module-aware n8n nodes with:

• ERPNext-specific resources and operations.
• Frappe API v1 and v2 support.
• Submit and cancel helper behavior.
• Read-only ledger verification resources where safety matters.
• Importable workflow artifacts for real ERP validation.
• Production security notes for credentials, webhooks, and response design.
• Cross-module workflows that mirror actual business operations.

In n8n, install the package you need from the Community Nodes interface:

n8n-nodes-erpnext-accounting
n8n-nodes-erpnext-buying
n8n-nodes-erpnext-selling
n8n-nodes-erpnext-stock
n8n-nodes-erpnext-hrms

For manual installation in a custom n8n nodes environment:

npm install n8n-nodes-erpnext-stock
npm install n8n-nodes-erpnext-accounting
npm install n8n-nodes-erpnext-buying
npm install n8n-nodes-erpnext-selling

All module packages use the shared ERPNext API credential pattern:

Site URL: https://erp.example.com
Site Host Header: erp.example.com
API Key: your ERPNext API key
API Secret: your ERPNext API secret
Ignore SSL Issues: false

For private VPS or container deployments, n8n can call ERPNext through an internal URL while still sending the public Frappe site host header:

Site URL: http://erpnext.internal:8001
Site Host Header: erp.example.com

The project favors operational safety over broad, unchecked API exposure:

• Use dedicated ERPNext API users.
• Scope roles to the exact DocTypes used by each workflow.
• Prefer explicit fields for public webhook responses.
• Treat Stock and Accounting workflows as high-impact operations.
• Deactivate temporary write-test workflows after verification.
• Do not expose generic Custom DocType or Frappe Method workflows publicly.
• Use VPN, reverse proxy auth, header auth, IP allowlists, or shared secrets for public webhooks.
• Reduce saved n8n execution data for workflows that process financial, inventory, payroll, or customer records.

Planned direction:

• Keep module READMEs concise and production-focused.
• Add focused workflow documentation for retail, manufacturing basics, FMCG/Fresh, multi-company, and coverage matrices.
• Keep V1 focused on maintenance, issue response, documentation fixes, and dependency/security updates.
• Build Core V2 only when enough real issues and custom ERPNext examples arrive.
• Position Core V2 as a Frappe/ERPNext Customization Bridge: Custom DocTypes, custom fields, dynamic metadata, child tables, method helpers, and schema translation for real ERPNext/Frappe customization pain points.
• Add additional modules only when they can follow the same live-tested standard.
• Expand automated tests for request construction, endpoint selection, and credential redaction.
• Keep the ecosystem modular so teams can install only the ERPNext domain they need.
