Key Features
1. Two Ways to Generate E-Way Bills:
Using IRN: This approach relies on the generated IRN for validation before creating the e-way bill.
Without IRN: For cases where the IRN is unavailable, an e-way bill can be generated independently.
2. E- Way Bill Details and IRN Details: The invoice form view contains tabs dedicated to E-Way Bill Details and IRN Details, allowing for structured and accessible record-keeping.
3. MasterGST Integration:
API Integration: The module utilizes MasterGST, a third-party service, to interact with the government GST portal via APIs. When an e-way bill or e-invoice request is initiated, Odoo sends the request through MasterGST, which then forwards it to the government portal.
Credential Management: In the Dashboard under E-Way Credentials, sandbox (testing) and production keys, such as Client ID, Secret ID, Username, and Password, are managed. MasterGST credentials are stored securely and used for authentication with the GST portal.
4. E-Invoice Compliance:
Required for businesses with annual turnover above ₹5 crore.
E-invoices simplify the invoicing process by allowing electronic exchange of invoice data, reducing errors, and improving compliance with government standards.
