# GST Manager for WHMCS

GST Manager makes your WHMCS invoicing **GST-compliant for India**. It sets up the right tax
rules, prints proper GST invoices, classifies clients as B2B or B2C, handles export invoices,
and gives you the CSV reports you need at filing time — with a guided wizard that configures
everything on first run.

::: info A quick vocabulary
**GST** is India's Goods and Services Tax. **GSTIN** is your 15-character GST registration
number. **IGST / CGST / SGST** are the inter-state / central / state components of GST. **SAC**
codes classify services for tax; **Purpose Codes** (RBI) classify export payments. **B2B** means
a client who has a GSTIN; **B2C** means one who doesn't.

## Who it is for

An Indian WHMCS business that needs its invoices and tax reporting to satisfy GST rules —
correct IGST vs CGST/SGST on every invoice, compliant invoice formatting, export-invoice (FEMA)
handling, and clean GSTR-1 data — without wiring any of it up by hand.

## What it does

| Area | What you get |
| --- | --- |
| **Tax rules** | Auto-generated IGST 18% and CGST 9% + SGST 9% rules for your registered state |
| **Invoices** | GST-formatted invoice PDFs with your GSTIN, SAC/Purpose codes, and per-currency bank details |
| **Reports** | GSTR-1 (B2B/B2C), Export Invoices, and a combined legacy CSV — all by date range |
| **Compliance** | Indian financial-year dashboard widgets and health checks that flag GSTIN and zero-tax issues |
| **Safety** | HMAC-SHA256 file-integrity verification and one-click updates with an automatic backup |

## The guided setup

On a fresh, licensed install, opening **Addons → GST Manager** launches a **7-step Setup
Wizard** that walks you through licensing, WHMCS prerequisites, your GSTIN and tax rules, company
identity, SAC/Purpose codes, bank & export details, and invoice-template deployment. Only the
GSTIN step is mandatory; everything else can be skipped and finished later. See
[the setup wizard](/gst-manager-whmcs/features/setup-wizard).
