PDF tools for contracts and invoices
Quick answer
Create the invoice itself with the Invoice Generator, sign a contract with Sign PDF, mark a document CONFIDENTIAL with Watermark PDF, and combine supporting receipts or annexes with Merge PDF.
Free, no sign-up, and your file is read on your own device rather than uploaded.
Contracts and invoices share a set of needs: they need to look professional, often need a signature, sometimes need marking as confidential or a draft, and frequently travel with supporting documents attached.
This covers the full loop - creating an invoice from scratch, getting a contract signed, protecting sensitive drafts with a clear label, and combining everything into one file to send.
Step by step

Draw or type a signature and place it on the signature line.

Tips
- Sign a contract, then combine it with any annexes or supporting pages in the same visit, so the recipient gets one complete file.
- A CONFIDENTIAL watermark on a contract still being negotiated makes its status clear to everyone who sees it - remember it is a visible label, not a security measure.
- If an invoice needs to reference numbers from a longer PDF report, PDF to Excel can pull those figures into a spreadsheet first.
Common problems
A contract needs a signature but printing and scanning is not practical.
Sign PDF places a drawn or typed signature directly on the document - the same visual result as a printed-and-scanned signature, without the printer.
An invoice and its supporting receipts need to be sent as one file.
Use Merge PDF to combine the invoice with the receipts, in the order you want them read.

- Can I sign a contract without printing it?
