GST E-Invoicing Solution for Dynamics NAV and Dynamics AX

As GST compliance continues to evolve in India, one area that has brought significant operational change for businesses is GST E-Invoicing. For organizations running Microsoft Dynamics NAV or Dynamics AX, ensuring seamless e-invoice generation and integration with the government’s Invoice Registration Portal (IRP) can be challenging, especially when dealing with multiple transactions daily.

That’s where Cetas GST E-Invoice solution for Dynamics NAV and Dynamics AX makes compliance simple, fast, and automated.

What Is GST E-Invoice?

GST E-Invoice, or electronic invoicing, is a digital system introduced by the GST Council of India to standardize how B2B invoices are reported and authenticated. Instead of manually uploading invoice details to the GST portal, businesses are now required to generate invoices electronically and get them validated by the Invoice Registration Portal (IRP) managed by GSTN (Goods and Services Tax Network).

Once an invoice is authenticated, the IRP issues a unique Invoice Reference Number (IRN) and digitally signs the document. The data is then automatically made available to both the GST portal and e-way bill system, minimizing manual entry errors and ensuring real-time tax reporting.

Who Needs to Comply with GST E-Invoicing?

E-Invoicing under GST has been implemented in a phased manner, starting with large enterprises and gradually expanding to smaller businesses. As per the latest notifications:

• Businesses with a turnover of ₹100 crore and above must comply with e-invoicing requirements (effective from January 1, 2021).
• Over time, the threshold has been lowered, bringing medium and small businesses under the e-invoicing net.

If your organization issues B2B invoices, export invoices, or supplies through e-commerce operators, you must generate GST-compliant e-invoices in the prescribed JSON format.

Why Businesses Using Dynamics NAV Need an Integrated GST E-Invoice Solution

For companies using Microsoft Dynamics NAV or AX, generating and uploading e-invoices manually can become time-consuming, error-prone, and difficult to scale. An integrated e-invoicing solution ensures that:

• Invoice data flows directly from Dynamics NAV to the IRP.
• The system automatically generates and validates IRNs and QR codes.
• Acknowledgment numbers are recorded back into Dynamics NAV in real time.
• All invoice data stays synchronized with the GST portal.

Cetas GST E-Invoice Solution for Microsoft Dynamics NAV

Cetas, a Microsoft Solutions Partner with deep expertise in Dynamics 365 and legacy systems, has built a seamlessly integrated GST E-Invoice solution that connects Dynamics NAV or AX directly with government-approved GST Suvidha Providers (GSPs) and the Invoice Registration Portal (IRP).

The result? Instant IRN generation, zero manual uploads, and full GST compliance, all within your familiar Dynamics NAV or AX interface.

Key Features of Cetas GST E-Invoicing Integration

Our solution enables real-time API-based integration between Dynamics NAV and the IRP/GSP network. It supports all e-invoice applicable documents, including Sales Invoices, Debit and Credit Notes, Stock Transfers, Export Invoices, Reverse Charge Transactions and Invoices via e-Commerce Operators. Here’s how Cetas supports your organization’s e-invoicing journey:

1. Real-Time E-Invoice Generation

For companies with lower transaction volumes, invoices can be validated on posting. When a sales invoice or credit memo is posted in Dynamics NAV, the system automatically generates a JSON file and connects to the IRP through a GSP API. Within seconds, the IRN and acknowledgment number are fetched and updated back into the posted document.

2. Bulk or Background Processing

For organizations with high transaction volumes, Cetas offers a bulk e-invoicing feature. Invoices are automatically queued and processed in the background, ensuring continuous operations without manual intervention.

3. JSON File Management

Microsoft’s Cumulative Updates for Dynamics NAV 2016 and later support exporting invoice data in JSON format. With the Cetas add-on, users can generate and import JSON files directly within NAV — eliminating the need for third-party tools or manual uploads.

4. Seamless IRP Integration via GSPs

Cetas has partnered with multiple authorized GSPs to ensure reliable, secure, and compliant data exchange between Dynamics NAV and the government’s e-invoice network. The system automatically retrieves the IRN and updates it into your NAV records instantly.

5. Flexible Configuration

Our GST E-Invoicing module is customizable to suit your company’s operational setup — whether you post invoices individually, in batches, or through automated workflows.
