GST invoicing that posts itself to the books

A tax invoice is four documents at once: a bill to your customer, a stock issue, a receivable, and a line in next month’s GSTR-1. tBiz writes all four from one screen, so the register and the ledger cannot disagree.

What you get

Every document type

Tax invoice, bill of supply, export with or without payment of tax, SEZ, and deemed export — each with the fields the rule actually requires, not a single template with the words changed.

Place of supply, decided for you

Intra-state splits into CGST and SGST, inter-state becomes IGST, and a bill-to/ship-to mismatch is resolved by the rule rather than by whoever is typing.

HSN and rate memory

An item carries its HSN and its rate. Change the rate once and every later invoice follows; the old ones keep the rate they were raised at.

Reverse charge, marked

RCM supplies are flagged on the document, kept out of your output tax, and carried into the 3B table where they belong.

Your own print template

Sixteen document types on a ruled ledger layout, with your letterhead, your terms and your bank details. What you see is what prints.

Credit notes that link back

A credit note references the invoice it reverses, reverses the stock, and lands in the same return as an amendment — not as a mystery negative.

How an invoice becomes four things at once

  1. Pick the party. Their GSTIN, state, credit limit and outstanding balance come up with them — so the person raising the bill can see whether it should be raised at all.
  2. Enter the lines. Keyboard-first, with HSN and rate remembered per item, and stock checked as you go.
  3. Save. The sale posts to the ledger, the stock issues from the chosen warehouse, the receivable opens against the party, and the GST registers update.
  4. Send it. Print on your template, email it, or send it on WhatsApp from the same screen.

Invoicing questions

Can I raise a bill of supply and a tax invoice from the same company?

Yes. The document type is chosen per invoice, so a composition supply, an exempt item and a standard taxable sale can all be billed from one company without switching anything.

Does the invoice number series follow the GST rules?

Yes. Numbering is continuous, per financial year, per document type and per branch if you use branches, and tBiz will not let you reuse or skip a number in a posted series.

Can I edit an invoice after it is posted?

You can, and the change is recorded — the audit trail keeps the old values, who changed them and when. Where an edit would break something downstream, such as a settled receipt, tBiz refuses and tells you which document is in the way.

Does raising an invoice reduce stock automatically?

Yes, from the warehouse on the line. That is the point of one ledger: there is no separate stock issue to remember and no end-of-month reconciliation between the sales register and the stock register.
