Integrating Your ERP with NRS E-Invoicing

Your ERP or accounting system is the source of your invoices. To be NRS-compliant, that data must flow to an Access Point Provider (APP) and on to the tax authority. Here’s how integration typically works.

The flow

Invoice created in your ERP or accounting software
Data sent to your chosen APP (via API, file upload, or certified connector)
APP validates and submits to NRS
You receive confirmation or rejection; you may need to store the validated invoice reference

Until that flow is in place and tested, you’re not fully compliant.

What to plan for

Connectors
Some APPs offer pre-built connectors for popular ERPs. Check whether yours is supported and what configuration is needed.

Custom integration
If there’s no connector, you’ll need an integration (API or file-based). That means development, testing, and ongoing maintenance.

Data quality
NRS and the APP will expect certain fields and formats. Your system must supply them consistently—tax IDs, amounts, dates, and so on.

Training
Finance and IT need to understand the new flow, how to handle errors, and where to look for validation status.
