How to Edit an Invoice PDF Correctly

Updated 2026-09-17 · 2 min read

Invoices are the document people most often need to correct: a wrong PO number, an outdated address, a line item that changed after the file was generated.

Because invoices are usually set in a tight table, the edit has to preserve alignment exactly.

Editing figures in a table

Amounts sit in right-aligned columns. Replace the full cell rather than one digit, and keep the same character count where you can, so the decimal point stays in its column.

Addresses and reference numbers

These are plain text lines and replace cleanly. Click the line, retype it and the block keeps its leading and left edge.

Keeping it defensible

Correcting your own invoice before issuing it is normal admin. Altering an invoice you received is a different matter — keep the original and note what changed.

Frequently asked

Can I change the total?

Technically yes on your own invoice, but remember any totals shown elsewhere and the VAT line must agree.

Will the logo be affected?

No, images are untouched by text edits.

Can I re-date an invoice?

Yes, the date is ordinary text.
