01 · Before BillLitz
Reprints and corrections get confusing
Teams often re-send PDFs, overwrite numbers, or lose context when a correction is required. That breaks trust with clients and makes it harder to reconcile records later.
BillLitz · LogicLitz
BillLitz is a free GST & VAT invoice generator that keeps issued bills as a final record, lets you reprint the PDF anytime, and supports correction duplicates with a new invoice number.
Before you try it
When an invoice is wrong, teams need a clean correction process and a reliable history. BillLitz keeps issued invoices on record as-is (with reprints), then allows “duplicate as correction” so you preserve audit-friendly continuity.
The BillLitz case
01 · Before BillLitz
Teams often re-send PDFs, overwrite numbers, or lose context when a correction is required. That breaks trust with clients and makes it harder to reconcile records later.
02 · Final record, on purpose
BillLitz treats an issued invoice as the final record. You can reprint the PDF any time without changing the original.
03 · Corrections without rewriting history
Instead of overwriting, duplicate as a correction with a new invoice number. This keeps your history consistent and makes “what changed” easier to understand.
04 · Tax-ready fields
BillLitz supports tax-invoice style fields and includes a history view so your team can track issued, duplicated, and reprinted records in one place.
05 · PDF you can share
When you need to send a billing document quickly, the product focuses on generating and reprinting a PDF you can share immediately.
