GST for Gujarat Traders and Diamond Industry
Gujarat's Surat is the world's diamond polishing capital. Rough diamond imports are exempt from GST, while cut and polished diamonds carry 1.5% GST (HSN 7102). Gujarat textile traders in Surat sell fabric at 5% or 12% GST depending on value — fabric below ₹1,000 per metre is at 0%, above is 5% or 12%. Large traders in Ahmedabad and Surat dealing in inter-state goods must carefully manage IGST credit flows. Gujarat also has many GSTP (GST Practitioners) helping small traders with their returns. Mundra and Kandla port-based import businesses deal with IGST on imports separately from domestic supplies.
Example
A Surat fabric manufacturer invoices a Delhi garment exporter: 5,000 metres of cotton fabric at ₹200/metre = ₹10,00,000 (below ₹1,000/metre threshold, so 5% GST on eligible fabric). IGST 5% = ₹50,000. Total invoice: ₹10,50,000. Delhi exporter claims ITC of ₹50,000 and gets refund if fabric is used in export garments.

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.
