A retainer agreement doesn’t have to be a legal document drafted by a professional — it has to be clear, signed by both parties, and specific enough to resolve disputes. You can build one yourself in under an hour if you know what it needs to contain.
What the template must include
A retainer agreement template that works in practice covers five areas. These aren’t nice-to-haves — each one prevents a specific type of dispute.
1. Service scope
This is the most important section and the most often written poorly. Define your services in terms that can be verified:
- If hours-based: “Up to 20 hours per month of [service category]. Hours reset on the 1st of each month and do not roll over.”
- If scope-based: “Four 800–1,200-word blog posts per month, one monthly newsletter, and up to 2 hours of calls.”
Then add what’s excluded. “Not included: paid media management, photography, video production, website development.” This list doesn’t have to be exhaustive — just cover the things a client might reasonably assume are included.
2. Monthly fee and payment terms
State the fee as a flat number, not an hourly estimate. State when it’s due (before the month begins, on the 1st) and how it’s paid (bank transfer, credit card, etc.).
Add a late-payment clause: “If payment is not received within 5 business days of the due date, work may be paused until payment is received.” This doesn’t have to be a threat — it’s a process. Having it in writing means you don’t have to make a judgment call every time a client pays late.
3. Cancellation notice period
Either party can cancel with 30 days written notice. If you want to protect your planning horizon further, include a minimum term: “This agreement has a minimum term of 3 months. After the minimum term, either party may cancel with 30 days written notice.”
Out-of-scope requests will happen. Document how they’re handled: “Requests that fall outside the defined services will be estimated and invoiced separately. Work will not begin until the client approves the estimate in writing.”
5. IP ownership
“Upon receipt of full payment, Client owns all work product delivered under this agreement. Contractor may include the work in a professional portfolio unless Client requests otherwise.”
Where to find free templates
Several freelance platforms offer free retainer agreement templates you can download and adapt:
- Bonsai (hellobonsai.com) — offers retainer contract templates by profession (designer, developer, copywriter)
- AND CO (by Fiverr) — basic retainer templates, free to download
- IPSE (for UK-based freelancers) — standard contracts including retainer structures
- Docracy — community-submitted legal documents including service retainers
Most of these are starting points, not finished documents. You’ll need to customize the service scope and payment terms for your specific engagement — the generic language won’t cover your particular situation.
Building it into your proposal workflow
The most efficient approach is to build the retainer terms directly into your proposal so that the document the client reviews and signs covers both the scope and the agreement. This way there’s no separate contract to send — the proposal is the contract.
When your proposal and your contract are the same document, you eliminate the extra step of sending a separate agreement — and you ensure the client sees the terms in context with the scope they’re agreeing to.
A proposal tool like Waco3 lets you structure a retainer as a recurring quote — monthly fee, service scope, and terms in one document. For digital signing, pair it with a free DocuSign or HelloSign account so the signed record is stored and accessible, which matters if a question comes up months into the engagement.
What to customize before sending
When you use a free template, the sections most likely to need customization are:
- The service scope — make it specific to your offering, not generic
- Payment timing — ensure it says “in advance” or “before services begin”
- The cancellation notice period — adjust based on how much lead time you need to replace the income
- Any jurisdiction-specific language — free templates often default to US or UK law; adjust for your location
Before sending the agreement, read it once imagining you’re the client, and once imagining a dispute has arisen. If anything is ambiguous in either reading, rewrite it.
A clear, free retainer agreement that both parties understand and sign is more valuable than an expensive legal document that sits in a drawer unread. The goal is a shared, written record of what was agreed — and you can build that yourself.
