# Website Subscription vs One-Off Build: Which Model Fits a 20–200-Person Firm?

If you’ve decided your firm needs a new website, the next question is how to buy it: commission a one-off build and pay for it up front, or take a managed subscription and pay monthly. Both can give you an excellent site. Where they differ is in what happens after launch, who carries the ongoing risk, and how the money works. Here’s an honest comparison for a 20–200-person B2B firm — including when each is genuinely the right call.

## The two ways to buy a website

There are two main ways to buy a business website: a one-off build, where you pay once to design and launch the site and then arrange everything else yourself, or a [managed subscription](/blog/what-a-managed-website-subscription-includes/), where a single monthly fee covers the build and everything needed to keep it running afterwards.

The choice isn’t really about quality — both can produce a first-class site. It’s about who owns the work of keeping that site good once it’s live, and how you’d rather pay for it.

## The one-off build: strengths and the after-launch problem

A [one-off build](/services/website-development/)‘s great strength is clean ownership: you pay once, the site is yours outright from day one, and you carry no ongoing commitment. You can hire any agency or developer you like, get exactly the site you specify, and walk away owning all of it.

The catch is that the project ends at launch — and a website doesn’t. Hosting, security, updates, plugin licences, SEO and the inevitable fixes all become yours to source, coordinate and pay for separately. The common result is the site that looked excellent on launch day quietly decaying over the following year, because once the agency has moved on, no single person owns keeping it good. Within a year it’s common to be quietly juggling a host, an occasional developer and perhaps an SEO freelancer — the exact fragmentation a clean one-off purchase was meant to avoid. There’s also the cash-flow reality: a professional build is £5,000–£15,000 or more, payable before the site has earned a thing.

## The subscription model: strengths — and the lock-in worry, addressed

A subscription’s strength is that the site stays alive after launch — one team keeps it fast, secure and optimised — and its usual drawback, being tied in, is one [**Agile One**](/services/premium-web-subscription/), our premium web subscription, removes. There’s nothing to pay until the site is live, the monthly cost is predictable, and a single accountable team handles the build and everything after it.

The instinctive worry about any subscription is fair: “am I tied in?” Plenty of agency retainers are designed to be difficult to leave, and finance and legal buyers in particular have learned to be wary. Agile One is built the other way round — there’s no minimum term and no tie-in; you can cancel any time with 30 days’ notice. The one condition concerns the website itself: because it’s built at no upfront cost, you own it free after 12 months, or you can buy out the remaining build cost to take it sooner. So the historical downside of “subscription” — the lock-in — doesn’t apply here. (The full detail on [ownership and cancellation](/blog/website-no-lock-in/) is worth a read if that’s your main concern.)

## Side-by-side: cost, risk, maintenance, ownership, time-to-value

Here’s how the two models compare on the things that actually matter to the decision:

| | One-off build | Managed subscription |
| --- | --- | --- |
| Upfront cost | £5,000–£15,000+ before launch | £0 — nothing until the site is live |
| Ongoing cost | Variable: hosting, fixes, SEO billed separately | One predictable fee (£500/month) |
| After launch | You source and coordinate everything | One team keeps it running |
| If it breaks | Find someone, brief them, pay per fix | Covered — one support channel |
| Optimisation over time | Only if you commission it separately | Technical SEO + AI readiness included monthly |
| Ownership | Yours outright on day one | Content/brand/domain day one; site after month 12 (or buy out earlier) |
| Time to value | Weeks to build, then it’s on you | 2–4 weeks, then kept healthy for you |
| Lock-in | None — you own it | None — cancel any time, 30 days’ notice |

A useful way to read that table is over time, not on day one. A one-off build can look cheaper up front — but a website has running costs whichever model you choose. Say a build costs £12,000, then £300–£600 a month once you add hosting, occasional development and light SEO: across two years that’s roughly **£19,000–£26,000**, and you’re the one coordinating it. Two years of the subscription is **£12,000**, with everything handled and the site actively maintained. The exact figures will vary with your situation, but the pattern holds — the one-off’s saving is mostly upfront, and it narrows, or reverses, as the real cost of keeping a site healthy accrues. So the deciding question is often less “what does it cost?” and more “who’s responsible for this a year from now?”

## Which fits you?

As a rule of thumb: choose a subscription if you don’t have an in-house developer and want the site kept healthy without managing it yourself; choose a one-off build if you need full custom control or have the resource to maintain it. More specifically:

**A managed subscription tends to fit when:**

- You don’t have an in-house developer or someone whose job is coordinating web vendors.
- Predictable monthly cost suits you better than a large upfront outlay.
- You want the site to keep improving — not just exist — after launch.
- You’ve been burned before by a site that was neglected once the agency left.

**A one-off build tends to fit when:**

- You want to own the site outright from day one and prefer a capital purchase to an ongoing cost.
- You need pixel-level creative control, or bespoke/enterprise functionality beyond a marketing site.
- You have an in-house team — or a trusted retained developer — to host, secure and maintain it.

That last point is the honest dividing line. If you specifically want to own the site outright from day one and have the resource to look after it properly, a [one-off build is the better choice](/services/website-development/) — and we build those too. The subscription earns its keep precisely when you’d rather not become your own web department.

For most firms in the 20–200 band without a dedicated web person, the subscription is the lower-effort, lower-risk default — you delegate the whole thing and get on with running the business. But the one-off route is the right answer often enough that it’s worth being straight about, rather than steering everyone towards monthly by default.

## Ownership, either way

Either way, the things that are recognisably yours — your content, brand assets and domain — are yours from day one. The only real difference is when the website build itself becomes yours: immediately with a one-off build, or free after month 12 on the subscription (sooner if you choose to buy it out).

That’s worth holding onto, because “you don’t own it straight away” is the most common objection to any subscription — and here it’s bounded and transparent rather than open-ended. You’re never in a position where you can’t get control of your own site; it’s simply a question of when, and on what terms you already know in advance. (If the cancellation and ownership detail is the part you most want to pin down, it’s worth [reading in full on its own](/blog/website-no-lock-in/).)

## Not sure which fits?

If you’re weighing it up, the quickest way to decide is to talk it through against your actual situation — your team, your timeline and how you’d prefer to pay. Tell us about your site and we’ll give you a straight recommendation, even if that’s the one-off route.
