Frequently asked questions

Everything you need to know about gst compliance & billing

Does Clyrix calculate CGST, SGST, and IGST automatically?
Yes. By comparing your company's registered state with your client's Place of Supply (or GSTIN prefix), Clyrix automatically applies either intra-state (CGST + SGST) or inter-state (IGST) tax rates.
Can I issue credit notes against existing invoices?
Yes. Credit notes link directly to the original invoice number and date in compliance with Section 34 of the CGST Act, adjusting taxable values and tax liability accurately.
How do export invoices work under LUT?
You can save your approved LUT number and valid date range in Settings. Export invoices will automatically apply 0% tax under LUT (EXPWOP) and format currency and bank remittance details.
Can my Chartered Accountant access the data for GSTR-1?
Yes. You can view clean GSTR-1 tax summaries or invite your team to your workspace.
