Connecting Your ERP to InvoiceNow: SAP, Oracle, Dynamics, Xero & QuickBooks

One of the biggest worries businesses have about InvoiceNow is disruption: will it mean replacing the accounting system we rely on? In almost all cases, no. InvoiceNow is designed to connect to the system you already run.

How integration works

An InvoiceNow-Ready solution sits between your accounting or ERP system and the Peppol network. It takes the invoice data your system already produces, converts it into PINT-SG, transmits it through an accredited Access Point, and reports the required data to IRAS - all without your team manually creating XML.

Common platforms

Accredited solutions typically integrate with the systems Singapore businesses use most, including:

• •SAP and Oracle for larger enterprises
• •Microsoft Dynamics for mid-market finance teams
• •Xero and QuickBooks for SMEs
• •Other accounting packages via API, file exchange or connectors

Integration patterns

Depending on your system and volume, integration usually takes one of a few forms:

• •Direct API integration for real-time, high-volume invoicing
• •SFTP or file-based exchange for batch processing
• •A connector or plug-in for popular accounting packages
• •A portal for manual or low-volume invoicing where no integration exists

What to check before go-live

Make sure your source data is clean and complete - GST registration numbers, tax category codes, line-item details and totals all need to map correctly to PINT-SG. Then run test transmissions through your provider's test environment to confirm invoices route correctly and the IRAS reporting flow works before switching on live traffic.

Keep your workflow, change the plumbing

Done well, ERP integration is invisible to most of your team: they keep raising invoices the way they always have, and the structured transmission and GST reporting happen behind the scenes. The goal is compliance without re-training your finance function.
