Sales or finance posts the invoice in your ERP as usual.
GST E-Invoicing · Microsoft Dynamics 365
GST e-invoicing, generated from your ERP, not typed into a portal.
We connect your billing to the Invoice Registration Portal so every B2B invoice gets its IRN and signed QR code automatically, with e-way bills, credit notes and returns data flowing from the same record. Set up, tested and supported by one team.

How GST e-invoicing works
Five steps, all triggered by posting an invoice
E-invoicing does not replace your invoice. It adds a validation step, so the invoice carries an IRN and QR code before it reaches your customer.
Send to the IRP
Invoice data goes to the Invoice Registration Portal through an API.
Validation
The IRP checks GSTINs, mandatory fields and duplicates.
IRN and QR returned
You receive a unique IRN, acknowledgement and signed QR code.
Print and share
The ERP stores them and prints the compliant invoice, while data feeds your GST returns.
Because this happens inside your ERP, your team never re-keys invoices into a portal, and rejected invoices show up with the reason straight away.
Recognize the signs
When e-invoicing is slowing your billing down
Many businesses meet the rule with workarounds. They work until volumes grow or a deadline is missed.
Invoices keyed in twice
Staff retype invoice data into a portal or upload sheet after billing.
Rejections found late
Wrong GSTIN, HSN or place of supply is caught after the customer waits.
Reporting window missed
Month-end batches risk invoices falling outside the portal's time limit.
E-way bills on another screen
Dispatch teams create e-way bills separately from the invoice.
Credit notes forgotten
Credit and debit notes are not reported, which creates return mismatches.
Returns do not match books
GSTR-1 totals and ledger figures need manual reconciliation every month.
What we implement
E-invoicing services that cover the whole GST workflow
From the first API call to monthly reconciliation, you get one accountable team for setup, integration, testing and support.
IRN and QR code generation
Invoices post to the IRP automatically, and the IRN, acknowledgement details and signed QR code print on your invoice format.
E-way bill integration
Generate, update and cancel e-way bills from the sales or transfer document, with transporter and vehicle details captured once.
Credit notes and cancellations
Credit and debit notes are reported the same way, and cancellations follow the portal's rules with a clear audit trail.
Master data validation
We clean GSTINs, HSN and SAC codes, units and state codes, so invoices pass validation the first time.
GST returns and reconciliation
E-invoice data lines up with GSTR-1 and your ledgers, and reports flag differences before you file.
Monitoring and support
We watch for rejected invoices and portal changes, update your setup when rules change and train new users.

Compliance
The rules that decide how your e-invoicing is set up
E-invoicing applies to GST-registered businesses above a turnover threshold, currently ₹5 crore, and the portal enforces time limits and cancellation windows. Rules are updated by GSTN from time to time, so we confirm your position during assessment and build the checks into your ERP.
What we configure for you
- Applicability and exemption check for each GSTIN
- Reporting time-limit alerts for large taxpayers
- IRN cancellation and credit-note handling
- Mandatory fields and validation before sending
- Retry and error queue for rejected invoices

Frequently asked questions
What is GST e-invoicing?
It is the system where B2B invoices are reported to the government's Invoice Registration Portal, which validates them and returns a unique Invoice Reference Number (IRN) and a signed QR code. The invoice then carries these details when it goes to your customer.
Is e-invoicing mandatory for my business?
It applies to GST-registered businesses whose aggregate annual turnover has crossed the notified threshold, currently ₹5 crore, with some categories exempt. Rules change from time to time, so we confirm your position for each GSTIN during the readiness check.
Which ERP and billing systems can you connect?
We work mainly with Dynamics 365 Business Central and Finance and Supply Chain, and we also integrate POS, custom ERP and in-house billing applications through APIs.
Can you also handle e-way bills and credit notes?
Yes. E-way bills, credit notes and debit notes are set up in the same integration, so they come from the same documents as your invoices.
What happens if an invoice is rejected by the portal?
The rejection and its reason appear inside your ERP, so your team can correct the data and resend. We also set up an error queue and alerts so nothing is left unreported.
How long does set-up take, and do you offer support?
It depends on the number of GSTINs, branches and invoice formats. We scope this in the readiness check and give you a phased plan, then stay on through go-live with AMC and support.
