What it does

E-invoicing turns invoicing into a system requirement. Invoices raised in ERP, accounting and billing tools must reach the framework in a structured format, and rejections must be fixed at source, without re-keying.

  • Validation

    Invoices are checked before they are sent, so rejections are caught and fixed at source.

  • Transmission

    Invoices are transmitted to the NRS e-invoicing framework.

  • Status tracking

    Each invoice carries its Invoice Reference Number (IRN) and a delivery status you can see, alongside its payment status.

  • Source-system integration

    ERP, accounting and billing systems are mapped and connected, so invoices flow without being re-keyed.

How it works

From your systems to the framework.

  1. Your systems

    ERP, accounting and billing tools raise invoices as they do today.

  2. ByteInvoice

    Validates each invoice, transmits it and tracks its status.

  3. NRS e-invoicing framework

    Receives the invoice and returns its status.

  4. Your team

    Sees what was delivered, what was rejected and why.

Use cases
