Should you charge a retainer for site maintenance?

Most agency owners ask this after a bad month — a run of small free fixes, an evening lost to somebody else's plugin update, the vague sense that the sites they shipped are quietly eating the business.

The answer isn't obvious, and the honest version of the argument has a real case on both sides.

The case for

It turns a cost into revenue. The unbilled hours are happening whether or not you charge. A retainer is the same work with money attached, and the money is predictable.

Recurring revenue changes the shape of the business. An agency that lives on projects lives on a sawtooth — good quarter, bad quarter, hiring decision you can't make. Even modest recurring income smooths that, and it's the thing that makes an agency worth buying if you ever want to sell it.

It makes the work schedulable. Free fixes arrive as interruptions. Retained work has a slot. The difference in real cost is larger than the invoice, because interruptions destroy the surrounding hours too.

Some maintenance is genuinely obligatory. Platform updates, plugin updates, certificates, backups, uptime, security patches. Somebody has to do it. If nobody is paying, it doesn't get done, and the site is a liability on your portfolio with your name on it.

It sets an expectation. A client paying a monthly fee asks for things through the agreed channel. A client paying nothing asks through whichever channel they're in, at whatever hour, because there's no frame.

The case against

You're selling insurance on a problem you created. If the site needs monthly attention, ask why. A brochure site for a dentist should not require a person every month. Some retainers are really a rent on fragility, and clients eventually work that out.

It's hard to sell and easy to churn. "£200 a month in case something goes wrong" is a difficult pitch to a small business, and the first month where nothing goes wrong starts a conversation about cancelling. A retainer you have to justify every quarter is a sales job you've given yourself forever.

It can become a fixed-price all-you-can-eat contract. Scope creep on retainers is the classic agency wound: the fee is fixed, the requests aren't, and after a year you're doing six hours a month for a two-hour fee. Policing that damages the relationship you were trying to protect.

It can hide the real problem. If you're being paid for maintenance, you stop counting how much maintenance there is. The incentive to build sites that don't need fixing quietly disappears — which is fine for the invoice and bad for the business three years out.

It's not always the client's bottleneck. Some clients would rather pay properly for two good improvements a year than a small fee for availability they never use.

The distinction that resolves most of it

Separate two things that get bundled into the word "maintenance":

Keeping the site alive. Hosting, updates, backups, certificates, uptime, security. Genuinely ongoing, genuinely obligatory, genuinely worth a fee. This is a real product and you should charge for it without apology.

Fixing things the client broke, and making small changes. Not obligatory. Mostly avoidable. Charging for it prices a problem instead of removing it.

The first is a service. The second is a symptom. A retainer that bundles both lets the second hide inside the first, which is why so many retainers feel uncomfortable to sell — part of what you're charging for shouldn't need to exist.

What to do with the second category

Three options, and they're not exclusive.

Remove the possibility. Most small "fixes" are content edits that broke the design. Build so that content is fully editable and design isn't — structurally, not as a permission — and the category shrinks to nearly nothing. This is the work Contentive exists to do, and it's why we'd rather sell a platform than a retainer.

Price it as work. A change request gets a quote. Clear, honest, no ambiguity about what's included. Clients respect this more than agencies expect.

Give a small allowance. An hour a month inside the care plan for odds and ends. Generous enough to feel good, small enough not to become a habit.

A reasonable position

Charge a care plan for keeping the site alive, priced at what it costs you plus a margin, and be able to say exactly what it covers. Bill improvements as work. Don't build a business on repairing the thing you shipped.

If you're currently doing the second category for free and considering a retainer to stop the bleeding, that's a reasonable short-term move. Just track how much of the fee is genuine upkeep and how much is repair — and if it's mostly repair, the retainer is treating a symptom you could remove instead.
