# Octa – User Guide

**Octa GST** is a cloud-based, high-performance GST compliance platform designed for modern businesses and tax
professionals. It simplifies every stage of GST compliance — from return preparation to filing — through smart
automation and an intuitive interface.

With Octa, you can manage **multiple GSTINs**, **reconcile** invoices, track **ITC**, and generate **reports**
effortlessly. It also supports **e-invoicing**, **e-waybill** generation, **ERP/API integration**, and **bulk Excel
exports**, giving you the accuracy, scalability, and efficiency needed for large-scale GST operations.

## I’m new to Octa GST

Start with the [**Getting Started**](/octa/docs/app/getting-started/overview) 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**](/octa/docs/app/reports/overview) 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**](/octa/docs/app/filing-gstr1/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**](/octa/docs/app/ims/overview) 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**](/octa/docs/api/einvoice/introduction) to get started.
