How to Add Text To an invoice PDF
Updated 2026-09-17 · 2 min read
The usual reason to add text to an invoice PDF is a wrong purchase-order number or an address that changed after the accounting system generated the file.
Adding text differs from editing it: there is no existing line to inherit a font and position from, so both are your responsibility.

Edit a PDFSteps to add text to an invoice PDF
Click an existing line first to see which font and point size the document uses.
Click where the new text should start and type it.
Apply the same font, size and colour, and align the left edge with a nearby text block.
Save — added text is part of the page, so it prints normally.
What to watch out for on an invoice
With this kind of document, figures sit in right-aligned columns, so keep totals and decimal points in their column.
One caution worth stating plainly: correcting your own invoice before issuing it is routine admin; altering one you received is not.
Why the result holds up
Misaligned left edges are the fastest way to make an addition look bolted on; matching them is what makes it look original.
