Use this template See the data it needs

The service agreement template filled with sample data. A two-party service agreement with numbered clauses, a schedule of deliverables and signature blocks. The wording is a sample only.

What this contract template is for

Use it when you send the same kind of agreement to many clients. It suits agencies, consultants, freelancers and software companies that sign service agreements often.

It works best with a contract you already have. Put your own wording in the template once. After that, each new agreement is filled with the client’s name, address, fees, dates and deliverables.

The wording in the sample is an example only, not legal advice. Have a lawyer check it, or use your own contract text.

What a good service agreement includes

Who the parties are, with their legal names and addresses.
What will be delivered, and when.
The fees, and when they are due.
How long the agreement lasts, and how either side can end it.
Confidentiality, and who owns the work.
Which country’s law applies.
Signature blocks for both parties.

FAQ

Questions about service agreement PDFs

How do I create a contract PDF?

Start from this template, or paste in your own contract. Mark the parts that change, such as names, dates and fees, as fill-in fields. Then send each client’s details and get a finished PDF back.

What should a service agreement include?

The parties, the services and deliverables, the fees and payment terms, how long it lasts and how it ends, confidentiality, who owns the work, and which law applies. It ends with signature blocks for both sides.

Is a PDF contract legally binding?

In many countries a signed PDF can be binding, but the rules differ. The wording in this template is a sample only. This is general information, not legal advice, so ask a lawyer before you rely on it.

Can I fill a contract template with each client’s details automatically?

Yes. Your system sends the client’s details with one request, and CastPDF returns the finished agreement. The clauses stay the same every time, so every client gets the wording you approved.

Can clients sign it electronically?

CastPDF makes the PDF but does not collect signatures. The PDF has signature blocks. Clients can print and sign it, or you can send it through the e-signature tool you already use.

Can I number the clauses and pages?

Yes, and both happen by themselves. Adding or removing a clause renumbers the rest. The sample names other clauses instead of quoting their numbers, so no reference goes stale. Each page shows “Page 1 of 2” at the bottom.
