Turn every shop order into a GST tax invoice and a filing-ready GSTR-1 or GSTR-3B report.

Filing GST every month means rebuilding GSTR-1 and GSTR-3B from Shopify exports by hand — hours of spreadsheet work, and one wrong tax split away from a notice. Catalyst turns each order into a GST-compliant tax invoice with HSN codes and the correct CGST, SGST or IGST split based on place of supply. Each tax period becomes a filing-ready GST report you can download or auto-email to your accountant. Packing slips, credit notes, B2B GSTIN capture and bulk printing are included.

GST reports ready to file: GSTR-1 Full, GSTR-1 B2B, GSTR-1 B2C and GSTR-3B
GST split automatically into CGST, SGST or IGST by place of supply and HSN
Branded tax invoices, packing slips and credit notes you can fully customise
Auto-email invoices to customers and send the GST report to your CA monthly
B2B GSTIN capture, location-wise GSTIN, bulk print and Shopify POS support
