I’m new to Octa GST

Start with the Getting Started section of this user guide. It walks you through the basics — logging in, adding companies or GSTINs, exploring your unified dashboard, inviting team members, and more.

I want to extract GST filing data

Octa GST lets you download all GST return data quickly and efficiently. Instead of working one GSTIN or one return period at a time, you can download reports at the PAN and financial year level.

Head to the Reports section to learn more.

I want to file GSTR-1

Easily generate and file your GSTR-1 with Octa GST. Simply import your sales register, and Octa will automatically create the required summary tables. With a single click, you can push your data directly to GSTN for filing.

Begin with Import Sales Register and continue from there.

I want to take actions on invoices in IMS

The Invoice Management System (IMS) introduced on the GST portal allows you to accept or reject invoices uploaded by your suppliers. This helps correct ITC flow to GSTR-3B. Octa GST helps you automate these reconciliations and recommended actions to save time and ensure accuracy.

Refer to the IMS section for detailed steps and automation features.

I want to integrate for E-Invoicing & E-Waybills

Octa GST offers simple, powerful e-invoicing APIs that integrate seamlessly with your ERP system, automating e-invoice and e-waybill workflows.

Check the API Documentation to get started.
