A good contract does not just protect you legally — it sets expectations that prevent 90% of client conflicts before they happen. Every marketing agency engagement, no matter how small or how well you know the client, should start with a signed agreement.
Scope of work: the most important section
Vague scope is the root cause of most agency disputes. "Social media management" means different things to every client. Your contract must define exactly what is included: number of posts per month, which platforms, whether ad management is included, how many revisions you will provide, and what requires an additional statement of work.
Define what is explicitly out of scope as clearly as what is in scope. A client who expects deliverables you did not include will feel misled even if you were technically correct. Over-communicate scope before the contract is signed to avoid the conversation later.
Payment terms that protect your cash flow
Specify payment amounts, due dates, and late fee policies in the contract, not in a follow-up email. Standard agency payment terms:
- Retainers: Due on the 1st of each month, paid in advance
- Projects: 50% deposit before work begins, 50% on delivery
- Late fees: 1.5–2% per month on invoices past due
- Paused work: Work stops on invoices more than 15 days past due
Require the deposit before any work begins, no exceptions. If a client pushes back on a deposit, that is a signal worth paying attention to. Threecus makes it easy to track payment status and send automated reminders for overdue invoices.
Termination and notice periods
Both parties need a clear path to exit the agreement. Standard agency contracts require 30 to 60 days written notice to terminate. This gives you time to find replacement revenue and prevents a client from walking out mid-campaign with unpaid invoices. Include what happens to work in progress if the contract is terminated: whether deliverables to date are owed, what is billable through the notice period.
Agencies that operate on monthly retainers without termination clauses are vulnerable to sudden cancellations. Protect your revenue with a minimum notice requirement in every agreement. See how retainer agreements fit into a sustainable agency model in our marketing agency retainer model guide.
Intellectual property and ownership
Specify when intellectual property transfers to the client. Most agencies transfer ownership upon receipt of final payment in full. Work that is unpaid remains the property of the agency. Include this clause explicitly to avoid disputes over creative assets, strategies, and data.
Also clarify what the client owns versus what you retain. If you develop internal tools, templates, or processes as part of their engagement, your proprietary methods remain yours. Only the specific deliverables transfer.
Building a contract template you can reuse
Have an attorney review your base contract once, then customize the scope and payment terms for each client. A template that you can update in 15 minutes is infinitely better than negotiating terms from scratch every engagement. Store your contract template in your CRM alongside each client record so you can send it and track its status without switching tools.
