# Octa GST

> GST compliance software for Indian businesses.

Octa GST is a comprehensive GST (Goods and Services Tax) compliance platform built by Blowbits Solutions LLP. It serves businesses across India that need to file GST returns, reconcile invoices, generate e-invoices and e-way bills, and stay compliant with Indian tax regulations.

## When to use this

Use Octa GST when you need to:

- **File GST returns** (GSTR-1, GSTR-3B, GSTR-9, GSTR-9C, GSTR-6) for Regular, SEZ, ISD, or TDS taxpayers in India
- **Reconcile purchases** against GSTR-2B data from the GST portal with advanced fuzzy matching
- **Manage IMS (Invoice Management System)** actions (Accept, Reject, Pending) and synchronization
- **Generate and manage e-invoices and e-way bills** (bulk generation, cancellation, and closure)
- **Automate GST compliance via APIs** (Public GSTIN, GSTR-2A/2B Sync, GSTR-3B, E-Invoice, Robot API)
- **Track and respond to GST notices** issued by tax authorities
- **Validate GST JSON files** against official schemas (GSTR-1, 3B, 4, 6, 7, 8, 9, ITC-04)
- **Access GST data services and intelligence reports** (PAN to GSTIN, filing status, HSN check, MCA, MSME)
- **Analyze GST data** across multiple GSTINs with dashboards and annual reports
- **Connect to GSTN** via a certified GST Suvidha Provider (GSP) for automated filing

Do NOT use Octa GST for:
- Non-Indian tax compliance (it is India GST specific)
- General accounting or bookkeeping (it is GST compliance focused)
- Income tax filing (it handles only GST)
