ERPNext Integration
ERPNext UAE E-Invoicing — FTA PINT-AE Integration 2026
TrustBill turns ERPNext into a UAE e-invoicing powerhouse. Keep your open-source ERP on self-hosted or Frappe Cloud — we generate PINT-AE XML, validate it against FTA rules, and submit through an accredited ASP.
How TrustBill integrates with ERPNext
ERPNext is an open-source ERP used by UAE manufacturers, trading houses, service firms and free-zone companies. It stores your customers, items, VAT, sales invoices and payments in one place, but it is not a Peppol/FTA-accredited e-invoicing solution on its own. TrustBill adds the missing compliance layer: a secure API connection reads invoice data from ERPNext, converts it to PINT-AE XML, validates the UAE mandatory fields, and routes the document to your buyer through an Accredited Service Provider (ASP).
One-time setup guide
Connecting ERPNext to TrustBill is straightforward and does not require core ERPNext code changes:
1. **Create your TrustBill account** — Sign up for free and enter your TRN and business details. 2. **Connect ERPNext** — Add an API key and site URL for your ERPNext instance (self-hosted or Frappe Cloud). 3. **Map master data** — TrustBill imports customers, items, tax templates and chart of accounts, and maps them to PINT-AE fields. 4. **Configure UAE rules** — Set VAT codes, free-zone flags, place of supply and invoice type codes. 5. **Send a test invoice** — Submit a test sales invoice to the Peppol network and confirm delivery status.
After go-live, every submitted ERPNext invoice is converted and transmitted automatically.
PINT-AE compliance for ERPNext invoices
The UAE Ministry of Finance requires PINT-AE structured XML for B2B and B2G e-invoices. TrustBill takes the native invoice data from ERPNext and builds a PINT-AE document that covers the mandatory and conditional fields: UUID, issue date and time, supplier/buyer TRN, legal names in English, line-item descriptions, unit prices, VAT rates, total with VAT and UAE-specific elements such as free-zone and margin-scheme indicators. Large businesses (revenue ≥ AED 50M) go live on 1 January 2027; SMEs follow on 1 July 2027.
Key features for ERPNext users
TrustBill's ERPNext integration includes:
- **API-based sync** — Uses the standard ERPNext REST API; no on-premise agent required. - **Self-hosted and Frappe Cloud** — Works with both deployment models. - **PINT-AE generation** — Native ERPNext invoices become UAE-standard XML. - **Real-time validation** — Errors are returned before submission with field-level guidance. - **Status tracking** — Track pending, submitted, accepted and rejected invoices in one dashboard. - **Credit notes and self-billing** — Supports PINT-AE credit notes and self-billed document types. - **VAT 201 integration** — Submitted e-invoices feed your VAT 201 return draft. - **Data residency** — Invoice data is processed and stored in the UAE.
Security and data ownership
You keep full ownership of your ERPNext database. TrustBill reads only the invoice and master data needed for e-invoicing and does not write back into your ERPNext ledger. All API calls use TLS 1.3, credentials are encrypted at rest, and you can rotate or revoke the API key at any time. For self-hosted deployments, the connection leaves from your own infrastructure, so sensitive financial data never has to be copied to a third-party server manually.
Frequently Asked Questions
Is ERPNext compliant with UAE e-invoicing?
ERPNext is not Peppol or FTA-certified by itself. With a connector like TrustBill, it can produce PINT-AE structured XML, but the actual network transmission must go through a UAE Accredited Service Provider (ASP).
Does the integration work for self-hosted and Frappe Cloud ERPNext?
Yes. TrustBill connects to both self-hosted ERPNext instances and Frappe Cloud sites through the standard REST API, as long as the endpoint is reachable over HTTPS.
How long does ERPNext e-invoicing setup take?
A standard ERPNext implementation with clean master data can be connected within a few hours. Heavily customised setups with custom doctypes or scripted workflows usually need one to two days of mapping and testing.
Is ERPNext suitable for UAE free-zone companies?
Yes. ERPNext is popular with free-zone SMEs. TrustBill handles mainland and free-zone invoice scenarios, including free-zone flags, TRN validation, and VAT treatment rules required by the FTA.
How is my ERPNext data kept secure?
TrustBill uses a read-only API connection, TLS 1.3 encryption in transit, encrypted storage for credentials, and never modifies your ERPNext ledger. You control the API key and can revoke access at any time.
