Pro Tips & Statutory Advice
Practical business & compliance advice
-
Interstate Supply & IGST Rules Always check your buyer's 2-digit GSTIN state code prefix. If it differs from yours, toggle Interstate Supply to charge IGST; charging CGST+SGST interstate can lead to buyer ITC denial.
-
Mandatory HSN Code Length Under Indian GST, businesses with turnover up to ₹5 Crore require at least 4 digits of HSN on B2B invoices; businesses with turnover above ₹5 Crore must include 6 digits.
-
Sequential Invoice Numbering Rule 46 requires invoice serial numbers to be unique per financial year and strictly consecutive, containing only alphanumeric characters and slashes/dashes.
-
Add Bank Account & UPI ID Always include your bank account number, IFSC code, and UPI handle directly on the bill so customers can pay immediately via IMPS/NEFT/UPI without payment delays.
