Frequently Asked Questions

Common questions about Upload Invoice on GSTN.

Using a GST software like LEDGERS can significantly simplify the process of uploading a large number of B2B invoices to GSTN.

LEDGERS also allows you to file your return directly from the software or download a JSON file to upload on the GSTN portal.

You must upload the invoice information in a data format, which includes details such as the customer's GSTIN, invoice number, invoice date, place of supply, total invoice value, and applicable GST rates and amounts.
If an invoice has multiple items with different GST rates, you can consolidate the items rate-wise when uploading the invoice details to GSTN.
