Goods come back, an extra charge is due, or an invoice was simply wrong. Fast Billing raises the correct document each time — an automatic credit note on a sales return that reverses the invoiced value, a debit note for extra charges or recovery, and a cancel-invoice that releases the dispatch so it can be re-billed correctly. A double-bill guard makes sure a shipped quantity is never billed twice. Cloud or on-premise.
A correction should never mean editing the numbers on a posted invoice. Fast Billing raises the right reversing or recovering document against the original dispatch, so the customer ledger and your accounts stay accurate. New to this? Read credit note vs debit note.
A sales return should not mean re-typing a negative invoice by hand. When returned goods come back against a dispatch, Fast Billing generates a credit note automatically — raised against that original dispatch, reversing the invoiced value for the returned quantity, and correcting the customer ledger. So the customer is credited for exactly what came back, tied to the invoice it relates to, with no guesswork about which sale it undoes.
Not every correction credits the customer. Sometimes they owe more — freight that was under-billed, a rate difference agreed after the invoice, or a short-supply recovery. A debit note raises that amount against the party, so the extra is a proper document on the ledger, not an awkward phone call. A credit note reduces what the customer owes; a debit note increases it — and both keep the account balance honest without touching the original invoice.
When an invoice is simply wrong — wrong party, wrong rate, wrong quantity — you don't want to edit the figures and pretend it never happened. Cancel-invoice voids it into a cancelled state and, critically, releases the dispatched quantity it had consumed, so that quantity is free to be billed correctly again. The original is kept for the record, the dispatch is freed, and the re-bill is a fresh, correct invoice — not a patched-over one.
Every reversal and re-bill only works because one rule holds underneath: a dispatched quantity can be billed once. Each invoice line is tied to the dispatch it bills, and the system tracks how much of that dispatched quantity has already been invoiced — so a new invoice can only bill the un-invoiced remainder. When you cancel an invoice, the guard precisely releases the quantity it had used, so the correct re-bill is allowed and nothing is double-counted. That is what keeps a busy billing desk honest.

Editing a posted invoice or typing a negative one is how ledgers drift and dispatches get billed twice. Here is what proper credit, debit and cancel documents change. New to the category? Read what is GST billing software?
When goods come back on a sales return, Fast Billing generates a credit note automatically against the original dispatch. It reverses the invoiced value for the returned quantity and corrects the customer ledger, so the customer is credited for exactly what came back — no re-typing, and no guesswork about which invoice it relates to. The credit note also posts to your accounts as a credit note.
A credit note reduces what the customer owes — it is raised on a sales return. A debit note increases what the customer owes, and you raise it for additional charges, short-supply recovery or a rate difference after the invoice. So a return credits the customer; a recovery or extra charge debits them. Both attach to the party and keep the ledger accurate. Our credit note vs debit note guide has worked examples.
Cancel-invoice voids a posted invoice and moves it to a cancelled state. Critically, it releases the dispatched quantity that invoice had consumed, so that quantity is free to be billed correctly again. It is how you undo a wrong invoice cleanly, rather than editing the figures — the original is kept, the dispatch is freed, and the re-bill is a fresh, correct invoice.
Every invoice line is tied to the dispatch it bills, and the system tracks how much of each dispatched quantity has already been invoiced. A new invoice can only bill the un-invoiced remainder, so the same dispatched quantity cannot be billed twice. When you cancel an invoice, the guard precisely releases the quantity it had used, so the correct re-bill is allowed and nothing is double-counted.
Yes. Credit notes post to your accounts as credit notes and debit notes as debit notes — to Tally and other tools — so the customer ledger in your books matches the operational document without re-keying. Your accounting stays the book of record; Fast Billing feeds it the correct reversal or recovery.
