Accurate Tax Logic
Automatic CGST, SGST & IGST calculation with historical snapshots
When you issue an invoice in ZyBill, the platform checks your firm’s state code against the customer’s state code and applies the exact GST split required for intra-state or inter-state billing.
Intra-state supply (Same State): Splits the GST rate equally into CGST and SGST on each line item and invoice summary.
Inter-state supply (Different State): Applies IGST with place of supply recorded on the invoice snapshot.
Credit Note Adjustments: Issued sales credit notes reduce effective invoice receivables and adjust period GST summaries accurately.
Frozen Document Snapshots: Issued invoices preserve the exact seller and buyer GSTIN, address, and tax lines from the day of billing.

How does ZyBill decide between CGST + SGST and IGST?
ZyBill compares your business state code with the customer’s state / place of supply on the document. Intra-state supplies automatically split tax equally into CGST and SGST, while inter-state supplies apply IGST.
Can both GST-registered and unregistered Indian businesses use ZyBill?
Yes. You can configure your GST registration status in Settings, add GSTIN and state details for B2B and B2C GST invoicing, or issue clean bills while completing GST setup later.
Does ZyBill support HSN and SAC codes with rate-wise GST summaries?
Yes. Products and services store HSN or SAC codes and applicable GST rates. ZyBill generates HSN summaries, B2B/B2C breakdowns, and rate-wise GST reports from your issued invoices and credit notes.
Does ZyBill file returns directly on the government GST portal?
No. ZyBill prepares GST compliance summaries and GSTR-ready exports (such as GSTR-1 preparation data) to make return preparation easy for you or your CA, while statutory portal filing remains outside ZyBill.
What happens if a customer’s address or GSTIN changes later?
ZyBill freezes seller and customer snapshots on issued financial documents so historical tax invoices remain intact and auditable even if master records are updated later.
