Chapter 01 · The bottom line
The short answer
Project work has a structural problem: every project ends, and you start selling again from zero. Retainers fix it by converting the relationship into recurring income. They work when the client has an ongoing need — maintenance, regular content, continuous optimisation, being available when something breaks. They fail when there's no genuine recurring requirement and the client is.

Practical guide
Project work has a structural problem: every project ends, and you start selling again from zero. Retainers fix it by converting the relationship into recurring income.
They work when the client has an ongoing need — maintenance, regular content, continuous optimisation, being available when something breaks. They fail when there's no genuine recurring requirement and the client is paying for the idea of access.

Two structures dominate. A defined-deliverable retainer covers agreed outputs each month: predictable for both sides, easy to price, easy to prove value. An access or capacity retainer buys a block of your time or priority availability: simpler to sell, riskier for you, because the scope has no natural edge.
Recommended: Stripe
Takes card payments and subscriptions worldwide without you touching card data.
Try Stripe →Protect yourself either way. Define what's included and what's billed separately. State response times rather than implying constant availability. Cap hours if you're selling capacity, and say what happens to unused ones — expiring monthly is standard and should be said plainly at the start.
Price above the equivalent hourly total, not below. Clients are buying reliability and priority; discounting the retainer trains them to see it as a bulk deal.

Agree a minimum term with notice on both sides, and review every six months against what actually happened.
Then keep proving it. The main reason retainers get cancelled is invisibility: a short monthly summary of what was done and what it achieved is what keeps the agreement renewing.
