FAQ

Quick answers to frequently asked questions about GST Manager for WHMCS.

Terminology

• GSTIN: 15-character Goods and Services Tax Identification Number.
• IGST / CGST / SGST: Inter-state / central / state components of Indian GST.
• SAC Codes: Service Accounting Codes classifying services for tax.
• Purpose Codes: RBI codes classifying international export payments.
• B2B vs B2C: Business-to-Business (client has GSTIN) vs Business-to-Consumer (unregistered).

Does it set up my GST tax rules automatically?

Yes. GST Manager creates the required WHMCS tax rules automatically during setup or under System Setup → Tax & GST:

• IGST 18%: Inter-state transactions across India.
• CGST 9% + SGST 9%: Intra-state transactions within your registered state.

What's the difference between B2B and B2C?

• B2B (Business-to-Business): Clients who supply a registered GSTIN.
• B2C (Business-to-Consumer): Unregistered clients without a GSTIN.
• GST Manager automatically classifies paid Indian invoices for GSTR-1 filing. See Tax reports.

Can I file GSTR-1 from this?

Yes, by generating statutory export CSV files:

• Go to Addons → GST Manager → Tax Reports.
• Download the GSTR-1 Export (B2B/B2C Classification) CSV for any date range.
• Upload or transcribe the classified data directly into the official GST portal.

Does it handle export invoices and FEMA?

Yes. Export compliance features are fully integrated:

• FEMA declarations: Configurable under System Setup → Export Settings.
• Dedicated numbering: Independent sequential numbering series for export invoices.
• Export reporting: Dedicated Export Invoices CSV detailing Purpose Codes and SAC per line item.

Will it change my existing invoice numbering?

No. GST Manager preserves existing WHMCS numbering while offering dedicated series:

• Domestic numbering: Uses standard WHMCS sequential numbering (e.g. INV-20251001).
• Export series: Optional separate sequential series for international clients.
• Existing historical invoices remain untouched. Configure under System Setup → Invoicing.

Are my invoices GST-format PDFs?

Yes. GST Manager deploys custom templates containing:

• Registered GSTIN and company identification footer (PAN, CIN/LLPIN).
• Line-item SAC and Purpose Codes.
• Multi-currency bank and remittance instructions.
• Deploy templates during setup or re-sync via Global Settings → Sync Status.

What are the dashboard widgets and why April–March?

GST Manager adds three WHMCS admin home widgets: Billing, GST Collected, and GST Compliance Health.

• Financial Year tracking: Reports across the statutory Indian financial year (1 April – 31 March).
• License requirement: Widgets display while an active license is verified.

Do I need to configure SAC codes?

Default SAC codes ship pre-configured for standard hosting and domain services:

• Standard service defaults apply automatically.
• Custom product overrides can be mapped under Addons → GST Manager → Item Rules.

What happens if my license lapses?

• Invoicing & tax rules: Invoicing calculations, PDF generation, and tax reports continue functioning normally.
• Client-area bank details: License-gated bank details block hides on client invoices until renewed.
• Lifetime licenses: Lapsed Support & Updates only restricts access to new module updates. See Licensing.

Is my data kept if I deactivate?

Yes. Deactivation preserves module database tables and historical records:

• Reactivating the module restores all settings losslessly.
• To purge data permanently, drop the mod_gst_* database tables manually. See Uninstalling.

How do updates and backups work?

• One-click updates: Run via Global Settings → Update Status → Check for Updates → Update Now.
• Automated backups: Creates a pre-update file and database snapshot, with automatic rollback on error.
• Retained database dumps: Download SQL backups from Update Status → Database Backups.

Can I show different bank details per currency?

Yes. Configure currency-specific remittance details under System Setup → Bank Details:

• Invoices in INR show domestic bank and IFSC information.
• Overseas currency invoices (e.g. USD, EUR) display international SWIFT/IBAN instructions.

What if my GSTIN is invalid?

• Setup validation: Wizard Step 3 validates format and blocks invalid entries in red.
• Compliance health: The GST Compliance Health widget flags malformed supplier or client GSTINs. See Troubleshooting.

Do I need an active WHMCS store selling to India?

Yes. GST regulations apply to Indian sales. GST Manager is built specifically for billing Indian clients and overseas exports. Review Requirements before installation.
