Configuration

Configure GST Manager settings after activation. For the field-by-field reference, see the Settings reference.

Vocabulary

GSTIN is your 15-character GST registration number. IGST / CGST / SGST are the inter-state / central / state components of GST — inter-state sales attract IGST; sales inside your own registered state split into CGST + SGST. SAC codes classify services for tax; Purpose Codes (RBI) classify export payments; FEMA governs export remittances.

1. Run the Setup Wizard

On a fresh, licensed install, opening Addons → GST Manager launches a guided 7-step Setup Wizard:

• License verification: Validates active module license status.
• WHMCS prerequisites: Auto-configures required tax and currency settings.
• Tax rules: Captures GSTIN, registered state, and generates GST rules.
• Identity & codes: Records company identity, SAC codes, and RBI Purpose codes.
• Template deployment: Syncs GST invoice templates to active themes.

Only the GSTIN & Tax Rules step is mandatory — every other step provides a Skip for now option. See the Setup Wizard.

Upgrading?

The wizard only appears on a fresh install. Upgrading does not trigger it — your existing settings are kept.

2. Where each setting lives (System Setup)

Access settings directly under Addons → GST Manager → System Setup:

Section	What you set here
Invoicing	Proforma Invoicing and Sequential Numbering (e.g. INV-20251001)
Tax & GST	Tax Type, your GSTIN, and generation of the GST tax rules
SAC & Purpose Codes	Default SAC + RBI Purpose code per service type
Footer & Identity	Phone, email, PAN and CIN/LLPIN printed in the invoice footer
Bank Details	Remittance/bank details, configurable per invoice currency
Export Settings	FEMA declarations, export numbering and export formatting

Addons → GST Manager → System Setup

Every field and default is documented in the Settings reference.

3. Set your GSTIN and registered state (mandatory)

Navigate to System Setup → Tax & GST → enter your 15-character GSTIN → select your registered state → save.

GST Manager generates the required tax rules automatically:

Rule	Applies to
IGST 18%	Inter-state supplies (country = India)
CGST 9% + SGST 9%	Supplies within your own registered state

An invalid GSTIN is rejected — double-check the 15 characters before saving.

One-Click System Setup

One-Click System Setup configures invoicing, the tax rules and your GSTIN in a single step. Fine-tune anything afterwards.

4. Set Company Identity

Sample placeholders print on real invoices

GST Manager ships sample placeholders for identity, bank and export details (for example +91-1234567890 and PAN ABCDE1234F). If you skip Footer & Identity, those placeholders print on real customer invoices. Set your own phone, email, PAN and CIN/LLPIN under System Setup → Footer & Identity before you go live.

5. Fine-tune per-item codes

Defaults under SAC & Purpose Codes cover standard service types (Hosting, Upgrades, Domains, Addons). For product-specific codes, configure mappings under Item Rules.

6. Verify

• Raise test invoices: Verify domestic CGST/SGST, inter-state IGST, and footer details.
• Check SAC/Purpose codes: Confirm codes display accurately on line items.
• Export tax reports: Download filing CSVs from Tax Reports.
