Manage invoices, quotes, and contracts as a freelancer

1 min read·25 July 2026

As a freelancer, you work with PDFs every day: sending invoices, writing quotes, signing contracts. PDFrust gives you all the tools you need — no subscription, no uploads to servers.

Professional invoices and quotes

Create your invoice in Word or a billing tool and export as PDF. Add your signature with the sign tool. Apply a "PAID" stamp when an invoice is settled using the stamp tool. Always keep the original and the stamped version separately.

Sign and return contracts

Received a contract as a PDF? Use the formFill tool to complete any fillable fields and the sign tool for your signature. Save the result and send it back. No printer, scanner, or fax needed.

Protect your quotes

Sending a detailed quote and want to prevent clients from editing the prices? Flatten the PDF after creating it — this makes text non-editable. Add a "QUOTE - VALID 30 DAYS" watermark for clarity.

Bundle project documentation

At the end of a project, merge all documents (letters, invoices, contracts, photos) into one PDF using the merge tool. Add page numbers and archive the bundle. Perfect for tax filing or client records.
