02Flat fees vs retainers — what they actually cost you.

Two numbers. One business.

On the left: a digital agency quoting “£1,500 a month, rolling, cancel any time”. On the right: a solo studio quoting “£1,000, flat, one-off”. It is not obvious, on first glance, which is the better deal — and the answer is genuinely not the same for every buyer.

Here is a plain-English look at both pricing models: what they actually cost, what they actually buy, and how to decide which one fits you.

The flat fee, honestly

A flat fee means: one number, one project, one outcome. You pay it, you get a site, you own it, the studio goes away.

It looks expensive for a single reason: it’s one line on one invoice. Nothing is hidden over 24 monthly statements. You see the whole cost at once, which makes it feel larger than it is.

What you’re paying for:

• A defined scope, agreed up front, with a defined deliverable.
• A finite project — it starts and, importantly, it ends.
• Handover: the code, the account, the deploy pipeline, the CMS if there is one. You leave with the keys.
• Clear exit: if you never speak to the studio again, the site still works.

What you’re not paying for:

• Ongoing strategy calls, monthly reporting, “optimisation sprints”.
• Someone else’s opinion on what to change next quarter.
• A seat at someone else’s weekly standup.

The clean version: a flat fee is the price of owning a thing. It is closer to buying a piece of furniture than renting one.

The retainer, honestly

A retainer means: a monthly number, usually rolling, often with a minimum term. You pay it, and in exchange a studio is available to you — to design, build, tweak, advise, iterate — as part of an ongoing relationship.

It looks cheap for exactly the reason a flat fee looks expensive: the cost is sliced into small monthly pieces. £1,500 a month reads very differently to £18,000 a year, which is what it actually is.

Over two years, that same “cheap” retainer has cost you £36,000. Over three, £54,000. For context, a small-business website delivered as a flat fee is usually somewhere between £1,000 and £15,000. The annualised retainer starts exceeding flat-fee pricing almost immediately.

£1,500 a month is £18,000 a year. It’s the same number, wearing a different suit.

That’s not to say retainers are a rip-off. What they’re buying is real:

• Continuity — the same team who knows your business, on standby.
• Responsiveness — changes land in days, not after another procurement cycle.
• Shared stake in the long arc — someone thinking about your site when you aren’t.

The right framing is: a retainer is the price of a relationship, not a site. If you want the relationship, it’s fair pricing. If you wanted a site, you’re overpaying.

The two numbers, side by side

Here’s the same small-business website, bought two different ways, over three years.

The final row is the one that tends to catch people out. On a lot of retainer contracts, the studio owns the code, the design files, and sometimes even the domain. If you stop paying, the relationship ends and so does access to the asset. This is worth reading for in any agreement before you sign.

Hidden costs on both sides

Neither model is pure. Both hide things.

What flat fees hide

A low flat fee can quietly compress scope. You get a site, but so stripped back it can’t grow with you. Or it’s built on a proprietary platform you can’t self-host, or a theme the studio doesn’t hand over cleanly. The cheap flat fee becomes expensive at the first change request.

Ask the honest questions: what exactly do I own? Can I host it anywhere? Can I edit it without you?

What retainers hide

Retainers often hide how little is actually happening. A common pattern: the first three months are busy, productive, worth the money. Months four through twenty-four consist of small tweaks, quarterly check-ins, and a “we should really do a refresh” conversation that never quite happens.

You’re paying full price for maintenance disguised as engagement.

Which one actually fits you?

The honest decision framework:

1. You’re a small service business, a consultancy, a practice, a solo founder, a one-location shop. You need a site, you need it to look and work well, you don’t need someone thinking about it monthly. Flat fee wins, almost always.
2. You’re a venture-backed SaaS, a high-churn e-commerce operation, or a publisher shipping content every week. Your site is a product, not a brochure. It changes constantly, and the cost of slow changes is measurable. Retainer wins — or better, hire in-house.
3. You’re somewhere in between — a small firm that does need occasional changes. Flat fee for the build, then a small hourly or ad-hoc arrangement for changes. You get the benefits of owning the asset without paying for a relationship you don’t need every month.

The unspoken asymmetry

One last thing that rarely gets said out loud. Retainers suit studiosfar more than they suit buyers. Predictable revenue, no constant sales cycle, long client tenure — a studio’s financial officer will recommend retainers every time.

That doesn’t make them bad. It makes them recommendedin situations where a flat fee would have served the client better. If a studio refuses to quote a project on a flat basis without a clear reason why, that’s information.

Pick the pricing model that matches the thing you’re actually buying. If you’re buying a site, buy it flat. If you’re buying a relationship, buy it monthly — with your eyes open about the annualised number.
