Turn it on
Open E-invoicing in the menu and choose how to connect. The connection to the Invoice Registration Portal through a GST Suvidha Provider is being finalised; until then the simulator lets you try the whole flow, and everything it makes is marked as simulated.
On an invoice
Post the invoice, then generate the e-invoice. OSuite checks it first and lists anything missing in plain words, such as a customer’s PIN code. The IRN and signed QR are printed on the invoice.
E-way bills
For goods, generate the e-way bill from the e-invoice with the distance and a vehicle number or transporter ID. It is valid one day for every 200 km.
