For invoices you issue yourself

This page is about invoices you write and send: a freelancer's monthly invoice, a studio's invoice built from a PDF template, an invoice typed in a word processor and exported. You spot a typo or a wrong date after exporting, and fixing the PDF is quicker than rebuilding it.

TweakPDF is only for documents you have the right to change, which here means invoices you issue yourself. If your accounting or invoicing system issued the invoice, correct it in that system so the records and the PDF match.

What you can change on your own invoice

  • Typos

    A misspelled item description, client name or street, caught before the invoice goes out.

  • Invoice number and dates

    The next number in your sequence, the issue date and the due date.

  • Quantities and amounts

    Hours, units, rates and the totals that depend on them.

  • Client details

    The name or billing address of the client you are invoicing.

Change the invoice number and amounts in the same font

An invoice is mostly figures in columns, and a figure in another typeface or slightly off its line looks wrong at once. TweakPDF draws the new value with the font embedded in the PDF, at the same size and color and on the original baseline, and adjusts the spacing so the other columns on that line stay where they were.

The old characters are deleted from the file rather than covered by a white box, so search and copy-paste find only the corrected number.

A PDF does not do arithmetic. If you change a quantity or a rate, also change the line total, the subtotal, any tax and the total due, and check in the preview that they add up.

Edit an invoice template PDF each month

Some people keep last month's invoice as their template. Open it, change the invoice number, the dates, the client and the amounts, and download a new file; the logo, layout and fonts stay as they were. If you sign your invoices, use Signature → Add signature in the same session.

3 files a month are free. If you send many invoices, Pro covers up to 1000 files a month for $6 a month.

What it does not do

TweakPDF changes text that is already on the invoice. It does not add or remove line items, recalculate totals, change the layout, fill interactive form fields, merge invoices into one file or open password-protected PDFs.

Questions about editing invoices

How do I change the invoice number in a PDF?
Open the invoice in TweakPDF, click the number, type the new one and press Save. It is set in the invoice's own font, and the old number is deleted from the file.
How do I fix a typo in an invoice PDF?
Click the misspelled word, type it correctly and press Save. The rest of the line stays where it was, so the layout of the invoice does not change.
Will the total update if I change a quantity?
No. A PDF does not calculate, so change the line total, the subtotal, any tax and the total due yourself, then check them in the preview.
Can I reuse an invoice template PDF?
Yes. Open last month's invoice, change the number, dates, client and amounts, and download it as a new file. You can replace text on existing lines but not add new rows.
My invoicing software made the PDF. Should I edit it here?
Correct it in that software instead, so the records it keeps match the invoice you send. TweakPDF suits invoices you make yourself, such as from a template or a word processor.
Is it free to edit an invoice PDF?
3 files a month are free: you edit and preview without an account and sign in with Google only to download. Pro costs $6 a month, $24 for six months or $36 a year.
Do you keep my invoice?
No. The file is deleted from the server two hours after you stop working, or right away when you press Delete file now.
