GSP Credentials: E-Invoice vs. E-Way Bill — Quick Comparison
| E-Invoice Portal | E-Way Bill Portal | |
|---|---|---|
| Website | einvoice1.gst.gov.in | ewaybill.gst.gov.in |

Underlying Concept (Accounting / Logic / Calculation)
Core GST Concepts
GSTIN (GST Identification Number): A 15-digit unique identifier assigned to every GST-registered business in India. It encodes the state code, the business's PAN number, and an entity type indicator. It is mandatory on all tax invoices.
GSP (GST Suvidha Provider): A government-authorized intermediary company that provides a secure API channel between third-party apps (like SIM) and the GST portal. A GSP allows SIM to submit and receive data from the GST system on behalf of the business. The GSP used by SIM is: BVM IT Consulting Services India Private Limited.
GSP Credentials (Username & Password): Separate from the regular GST portal login. Created specifically for API-based integration. Must be generated on the respective government portal (e-invoice or e-way bill) and then entered once in SIM. These credentials authorize SIM to act on behalf of the business on the GST portal.
API (Application Programming Interface): The technical communication layer between SIM and the government GST portal. The GSP username and password authenticate this connection.
IRP (Invoice Registration Portal): The government portal where B2B invoices are submitted and registered to receive an IRN.
IRN (Invoice Reference Number): A unique 64-character hash generated by the IRP for each registered B2B invoice. Once generated, the IRN is printed on the invoice along with a QR barcode and an acknowledgement number. An IRN confirms that the invoice has been officially registered with the GST system.
E-Invoice: A B2B invoice that has been registered with the IRP and assigned an IRN. The invoice itself is created in SIM; the IRN is obtained from the government portal via the GSP integration.
E-Way Bill (EWB): A digitally generated document required before transporting goods worth more than ₹50,000. It is submitted to the government e-way bill portal and contains details about the goods, origin, destination, and transporter. It must accompany the goods during transit.
Input Tax Credit (ITC): A mechanism that allows GST-registered businesses to reduce their GST liability by the GST they have already paid on their purchases. For a buyer to claim ITC, the seller must have issued a valid tax invoice with a proper IRN (for applicable cases).
