Indian – E-invoicing
====================
To submit invoicing through API to the government.
We use “Tera Software Limited” as GSP

Step 1: First you need to create an API username and password in the E-invoice portal.
Step 2: Switch to company related to that GST number
Step 3: Set that username and password in CBMS ODOO (Goto: Invoicing/Accounting -> Configuration -> Settings -> Customer Invoices or find “E-invoice” in search bar)
Step 4: Repeat steps 1,2,3 for all GSTIN you have in CBMS ODOO. If you have a multi-company with the same GST number then perform step 1 for the first company only.
