How to draft your client agreement and terms of business
Protect your business and build trust by clearly defining how you and your clients work together.
A Client Agreement or Terms of Business is your primary legal safety net; it ensures you get paid on time, defines exactly what work you will (and won't) do, and limits your liability if things go wrong. Without these documents, you are vulnerable to "scope creep," payment delays, and potential legal disputes that could threaten your livelihood.
The "Contractual Handshake"
In the UK, while a verbal agreement can be legally binding, it is incredibly difficult to prove in court. A written agreement provides clarity and professionalism. Usually, this is made up of two parts:
- The Engagement Letter: A document specific to the individual client that outlines the specific services you are providing right now and the agreed price.
- The Terms of Business: Your "standard" fine print that applies to every client. This covers the "what ifs"—like what happens if a payment is late or how to end the relationship.
What to include in your documents
Your agreement needs to be comprehensive but written in plain English so your clients actually understand what they are signing. Use the table below as a checklist for your first draft.
| Clause | What it covers |
|---|---|
| Scope of Service | A precise description of the work you will perform. Be specific to avoid doing extra work for free. |
| Fees and Payment | How much you charge, when invoices are sent, and your "pay by" dates (e.g., 14 days). |
| Late Payments | Your right to charge interest under the Late Payment of Commercial Debts (Interest) Act 1998. |
| Termination | How either party can end the contract and how much notice must be given (e.g., 30 days). |
| Liability | Limits the amount of money a client can claim from you if a mistake is made. |
| Confidentiality | A promise that you will keep the client's sensitive business information private. |
Managing "Scope Creep"
One of the biggest risks for new business owners is "scope creep"—when a client asks for "just one more thing" that wasn't in the original plan. Your agreement should clearly state that any work outside the defined scope will be charged at an additional rate. This empowers you to say, "I'd love to help with that; I'll send over a quick quote as it's outside our initial agreement."
Top Tip: Always include a "Jurisdiction" clause stating that the agreement is governed by the laws of England and Wales (or Scotland/Northern Ireland, depending on your location).
Finalising your draft
While you can find templates online to use as a starting point, every business is unique. A generic template might leave gaps that a disgruntled client could exploit. Once you have a draft that reflects how you want to work, follow these steps:
- Proofread for jargon: If a client can't understand a clause, they might be hesitant to sign it.
- Seek legal advice: Have a solicitor review your draft. It is an upfront cost that can save you thousands in the long run.
- Make it easy to sign: Use digital signature software to make the process seamless for your clients.
