Without a written agreement, you are relying on verbal promises that will not hold up in a dispute.

It gives you a written reference you can point to when disagreements arise, which resolves most issues before they escalate.
Use this contract before you write a single line of code, design a single asset, or deliver any work product. The few minutes it takes to customise and send this template can save you weeks of unpaid invoices and legal headaches later. Over 71% of freelancers report being paid late at least once per year; a signed contract with clear payment terms is the single most effective prevention tool.
This agreement works for both one-off projects and ongoing retainer relationships. For multi-project clients, pair it with a Statement of Work for each individual engagement so the master agreement covers the relationship while each SOW covers the specific deliverables.

Sample scenario
The situation: You start work with a new client based on a verbal agreement or brief email exchange. Scope, payment terms, and ownership are never formally documented.
The risk without a contract: The client can change requirements, delay payment, use your work without paying, or dispute ownership. Without written terms, every disagreement becomes a 'he said, she said' situation that you are likely to lose.
How this contract helps: This contract establishes clear payment terms, scope boundaries, IP ownership, and termination procedures. Both parties know exactly what to expect, which prevents most disputes before they start.
