• Statements of work (SOWs)
• Project proposals and quotes
• Invoices that require authorization signatures

• Client onboarding paperwork
• Intellectual property assignment agreements
• Non-compete and non-solicitation agreements
• Tax forms (W-9, VAT registration, etc.)

Why Freelancers Choose SigPDF

Affordable for Solo Professionals

Freelancers watch every expense. Enterprise e-signature tools like DocuSign ($10+/month), PandaDoc ($19+/month), or HelloSign ($15+/month) are priced for businesses with teams and budgets to match. SigPDF costs €2.08/month on an annual plan — less than a single cup of coffee. For freelancers, that means professional PDF signing without a significant overhead cost.

Privacy for Client Confidential Documents

As a freelancer, you regularly sign documents that contain sensitive information — client trade secrets in NDAs, financial terms in contracts, project details in SOWs, and personal tax information in contractor forms. When you use a cloud-based signing platform, all of this data passes through third-party servers.

SigPDF processes your PDF entirely in your browser. Your clients' confidential information, your personal details, and the financial terms of your agreements never leave your device. This is particularly important when signing NDAs — you are literally agreeing to keep information confidential, so it makes sense to use a tool that does not share that information with a third party during the signing process.

Sign Anywhere, on Any Device

Freelancers work from everywhere — home offices, coffee shops, co-working spaces, client offices, airports, and hotels. When a client sends a contract that needs to be signed urgently, you cannot always get to a printer. SigPDF works in any web browser on any device: your laptop, tablet, or phone. Open the PDF, sign it, and send it back — whether you are at your desk or on the move.

No Account, No Friction

When a new client sends you a contract to sign, the last thing you want is to spend time creating an account on a signing platform, verifying your email, and navigating a dashboard. With SigPDF, you go directly to the tool, open your PDF, and sign. No registration, no email verification, no learning curve. The signed document is ready in under a minute.

Common Freelance Signing Scenarios

Signing a New Client Contract

A new client emails you a service agreement as a PDF attachment. Open it in SigPDF, review the terms, add your signature and date on the signature line, download the signed PDF, and email it back. Total time: under two minutes. No printing, no scanning, no account creation.

Signing an NDA Before a Project

Before starting a project, clients often require an NDA. These documents contain confidential business information that you are agreeing to protect. Signing an NDA with SigPDF means the NDA itself — and any confidential details it mentions — never passes through a third-party server. Open, sign, download, send.

Authorizing an Invoice

Some clients require a signed copy of your invoice for their accounts payable department. With SigPDF, you can add your signature to the invoice PDF in seconds and send it along. The same applies to expense reports, purchase orders, or any financial document that needs your authorization.

Legally Valid Signatures

Electronic signatures created with SigPDF are legally recognized under the US ESIGN Act and the EU eIDAS Regulation. This means your signed freelance contracts, NDAs, and invoices carry the same legal weight as handwritten signatures. For standard business documents, no specific e-signature platform is legally required — the intent to sign is what matters.

Are electronically signed freelance contracts legally binding?

Yes. Under the ESIGN Act (US) and eIDAS Regulation (EU), electronic signatures on freelance contracts are legally enforceable. The contract is binding as long as both parties consent to electronic signatures, which is standard in modern business.

Can I sign invoices with SigPDF?

Yes. Open your invoice PDF in SigPDF, add your signature, and download the signed document. This works for invoices, purchase orders, expense reports, and any other financial document.

How much does SigPDF cost for freelancers?

SigPDF starts at €2.08/month on an annual plan, with unlimited document signing. There are no per-document fees or feature restrictions. You can try it instantly without an account — the subscription is only required for downloading signed PDFs.

Can my client and I both sign the same document?

SigPDF is designed for individual signing. You sign the document and send it to your client, who can then sign it with SigPDF (or any other tool) on their end. Each party signs independently.
