FAQs

Do I need to keep old invoices?

Yes, keep invoice records for compliance and audit needs.

Can wrong invoice data create penalties?

Yes, repeated mismatches can lead to notices and compliance issues.

Should B2B invoices include buyer GSTIN?

Yes, buyer GSTIN is important for return matching and ITC flow.

Can I file correctly without software?

Possible, but software reduces manual mistakes and saves time.

Why Businesses Stop Using Excel for GST Invoices

Manual GST calculation mistakes

One wrong CGST/SGST split or a misapplied rate triggers notices and ITC denial for your buyer.

Slow invoice creation

Copying last month's Excel file, updating dates, recalculating — 20 minutes for what should take 30 seconds.

Formatting breaks on every device

Excel invoices look different on every printer and PDF converter. Clients complain about unreadable layouts.

No easy sharing or payment link

Sending PDFs over WhatsApp with no way for clients to pay directly slows down collections.

Incorrect tax type (IGST vs CGST+SGST)

Excel can't auto-detect intra vs inter-state supply. Wrong tax type = ITC rejected for your buyer.
