Freelance invoices: a PDF workflow that saves you hours

You send a client an invoice as a Word file, a timesheet as a spreadsheet and two more attachments. Their accountant has to open each one separately — and your invoice quietly sinks to the bottom of the pile. One clean PDF gets you paid faster.

1. Always export the invoice to PDF

Word documents render differently on every machine and are easy to edit by accident. A PDF locks the layout exactly as you designed it, and nobody can "fix" your total by mistake.

2. Merge the invoice and its paperwork

Add your timesheet, delivery note or purchase order as extra pages after the invoice. Order: invoice → timesheet → everything else. Your client approves with one click instead of five.

3. Compress it and give it a sane name

Scanned attachments can easily hit 15 MB, and many company inboxes bounce anything that big. Compression gets most PDFs under 1 MB with no visible quality loss. Keep the filename consistent, e.g. `2026-10_invoice_042_ClientName.pdf`, so finance can find it in seconds.

Bonus: sign without a printer

If a client wants a signed invoice, sign the PDF right in your browser. No printing, scanning or blurry phone photos.

You can do the whole thing — convert, merge, compress and sign — for free on FileTools, no install and no sign-up.
