Any GST-registered business whose aggregate annual turnover has exceeded Rs. 5 crore in any financial year from 2017-18 onwards is required to generate e-invoices for all B2B supply transactions. This includes export invoices. Certain categories, such as banks, NBFCs, insurance companies, Goods Transport Agencies (GTAs), SEZ units, and government departments, are currently exempt.

An Invoice Reference Number (IRN) is a unique 64-character hash generated by the IRP for every registered e-invoice. It is derived from three parameters: the supplier’s GSTIN, invoice number, and financial year. An invoice issued without a valid IRN is considered legally invalid under GST and attracts penalties equivalent to 100% of the tax due or Rs. 10,000, whichever is higher.

SMARTeIS connects directly with GSTN’s accredited Invoice Registration Portals via API. When an invoice is generated in your ERP or accounting system, SMARTeIS submits it to the IRP in real time, retrieves the signed IRN and QR code, and returns the authenticated data to your system, all within milliseconds. We support all accredited IRPs, ensuring zero downtime even during peak filing periods.

SMARTeIS integrates with SAP (ECC and S/4HANA), Oracle ERP Cloud, Microsoft Dynamics 365, TallyPrime, Tally ERP 9, Zoho Books, and custom in-house ERP environments. Integration is available via REST API, bulk JSON/CSV upload, and pre-built direct connectors for Tally and SAP. Our implementation team handles all data mapping and go-live support.

Yes. SMARTeIS is purpose-built for enterprise environments managing multiple GSTINs, business verticals, and branch locations. All entities can be administered from a single unified dashboard with role-based and branch-level access controls, making it suitable for large groups, holding companies, and businesses with pan-India operations.

Yes. For transactions that require both an IRN and an e-Way Bill, SMARTeIS automatically triggers e-Way Bill generation from the same invoice data. This eliminates duplicate data entry, keeps your logistics and compliance workflows in sync, and reduces the risk of mismatches between invoice and e-Way Bill details.

SMARTeIS maintains redundant connections across multiple GSTN-accredited Invoice Registration Portals. If one IRP experiences downtime, the platform automatically reroutes your submission to an available IRP. This ensures your invoicing operations continue without interruption and your commitments to buyers and dispatch timelines are not affected.

All CBIC notifications, schema updates, and IRP technical specification changes are monitored and absorbed by the SMARTeIS compliance and engineering team. Updates are deployed to the platform without requiring any changes to your ERP setup or internal SOPs. Your business remains compliant with every regulatory revision, requiring no additional development effort on your part.

Failure to generate a valid IRN is treated as non-issuance of an invoice under GST law and attracts a penalty of 100% of the tax due or Rs. 10,000, whichever is higher. Issuing an invoice with incorrect details carries an additional penalty of Rs. 25,000. Invoices without a valid IRN are also ineligible for Input Tax Credit (ITC) claims by the buyer, which creates downstream compliance risks for your business relationships.
