GST invoice format: the complete field-by-field guide
Exactly what a compliant GST tax invoice must carry — your GSTIN and invoice series, the customer's bill-to and ship-to with GSTIN, each line with HSN or SAC, quantity, rate and taxable value, the CGST/SGST split for intra-state or IGST for inter-state, other charges, rounding and amount in words. Covers domestic versus export series, POS bills, and how software applies HSN and tax automatically from item and party tax maps.
Billing and Tally: a practical integration guide
How operational billing feeds your accounts without double entry. Confirmed tax invoices post as sales vouchers with CGST/SGST/IGST ledgers, receipts as receipt vouchers, credit and debit notes as the matching notes, and approved supplier bills as purchase vouchers. Tally stays your book of record while billing feeds it — and this is only one of several accounting tools Fast Billing can post to. Covers mapping ledgers, GST heads and common reconciliation pitfalls.
Credit note vs debit note: what's the difference?
Two documents people mix up constantly. A credit note reduces what a customer owes — raised on a sales return, an overstated invoice or a downward rate correction — while a debit note increases it, for short supply, extra charges or an upward correction. This guide covers when to use each, how a credit note is auto-raised against the dispatch it reverses, how a cancelled invoice differs from a credit note, and how both post to your accounts and GST returns.
