GST Feature Suite
Complete GST compliance, out of the box
CBIC-Compliant Invoice Format
Every invoice generated by Solastice follows the format prescribed by CBIC. All mandatory fields — GSTIN, place of supply, invoice number, HSN/SAC — are included automatically.
Auto CGST / SGST / IGST Calculation
Solastice detects whether a transaction is intra-state or inter-state based on the supplier and client GSTIN and applies the correct tax structure automatically — every time.
HSN & SAC Code Management
Store HSN codes for goods and SAC codes for services in your product catalogue. These auto-populate on every invoice, ensuring correct GST rate application.
Multi-Rate GST Support
Handles all GST rate slabs: 0%, 5%, 12%, 18%, 28%, and special compositions. Different products in the same invoice can have different rates — managed automatically.
GSTIN Verification on Clients
Store and display client and supplier GSTINs on invoices. Place of supply auto-determined, ensuring correct intra-state vs inter-state tax classification.
How It Works
How Solastice handles GST automatically
Client GSTIN → Place of Supply
When you select a client, Solastice reads their GSTIN to determine the state. If same as your registered state → CGST + SGST. If different → IGST.
Product HSN → GST Rate
Each product in your catalogue has an HSN code with a configured GST rate. When added to an invoice line, the correct rate auto-applies. No manual entry.
Tax Calculated Per Line
Tax is calculated per invoice line item, not just the total. This allows products with different GST rates to coexist on the same invoice accurately.
PDF Generated with All Fields
The invoice PDF includes: GSTIN, Invoice Number, Date, HSN, Tax Rate, CGST/SGST/IGST, Total Tax, Taxable Value — all CBIC-mandated fields.
Reports Ready for Filing
At month-end, generate your GSTR-1 (outward supplies) and GSTR-3B (tax liability summary) directly from your invoice data. Share with your CA or upload directly.
GST FAQ
Common GST questions
Does Solastice handle RCM (Reverse Charge Mechanism)?+
Yes. Solastice supports flagging transactions under Reverse Charge Mechanism. RCM transactions are correctly tagged on the invoice and in the GSTR reports.
Can I handle both goods (HSN) and services (SAC) in the same invoice?+
Yes. You can have mixed line items on a single invoice — some with HSN codes (goods) and some with SAC codes (services). Each line applies the correct tax rate independently.
What if my client is unregistered (URD)?+
Solastice supports billing to unregistered dealers. The invoice is generated without client GSTIN and GST is applied at the point of supply of the supplier.
Is the invoice format accepted for GST filing and audits?+
Yes. The invoice format follows CBIC guidelines and includes all mandatory fields. PDF invoices are also cryptographically signed with a SHA-256 hash for tamper-evidence.
Can I export my GST data for my CA?+
Yes. GSTR-1 and GSTR-3B reports can be exported in the format your CA needs for GST portal filing. You can also export all invoice data as CSV.
