Search for the best website builder for accountants and you will get a ranked list of platforms with monthly costs beside them. WordPress, Squarespace, Wix, Webflow, then a few practice-specific systems sold by software vendors. The lists are broadly accurate and almost entirely unhelpful, because the platform is rarely the reason a firm's website underperforms.

We have rebuilt or replaced sites for accounting firms across the UK and US. The pattern is consistent. Firms do not fail because they picked Squarespace over WordPress. They fail because nobody owned the site after launch, no page was written to answer a specific search query, and the enquiry form fed an inbox nobody checked on a Friday.

So this piece takes a different angle. We will look at what each route actually costs over three years, what each one demands from you operationally, and the conditions under which a DIY build is the right call.

Every mainstream builder in 2026 produces a site that loads acceptably, works on a phone, and can be indexed by Google. The gaps that existed five years ago have mostly closed. Wix still draws criticism from SEO practitioners for heavier page code and awkward URL handling, and that criticism has some basis, but a well-structured Wix site will outrank a badly structured WordPress site every time.

What separates a site that produces enquiries from one that does not is structure. A firm with twelve pages, each written against a real search query, each with a clear next step, will beat a firm with a beautiful five-page brochure regardless of the underlying software.

Ask a different question. Instead of which platform is best, ask: can I add a new service page myself in under an hour, without calling anyone? If the answer is no, the platform is wrong for you whatever the reviews say. Most firms need to publish regularly. A system that makes publishing awkward will quietly stop being used, and a site that stops being updated stops earning rankings within about a year.

The appeal of a DIY builder is obvious. Subscription costs for the mainstream platforms sit in the low tens of pounds or dollars per month, and you can have something live in a weekend.

The cost that does not appear on the pricing page is your time. Building a credible eight to twelve page firm website from scratch, including writing the copy, sourcing images, setting up forms, and configuring analytics, takes most partners somewhere between forty and eighty hours spread over several weeks. That is modelled from what firms have told us during handover conversations rather than a measured study, so treat it as a working estimate. Value that time at your own charge-out rate and the arithmetic changes considerably.

Then there is the ongoing element. Content needs adding, plugins need updating on WordPress, and forms break silently more often than people expect. Firms that DIY successfully tend to have one person, often a practice manager rather than a partner, who owns the site as a named responsibility with time allocated to it.

If nobody in your firm has that time, DIY is not cheaper. It is deferred, and the deferral usually lasts about eighteen months.

An agency build is worth paying for when the constraint is expertise or attention rather than money. Three situations in particular.

The first is when you are targeting competitive search terms. Ranking for something like accountants for e-commerce businesses requires a page architecture designed around search intent, internal linking that reinforces topical authority, and content depth that takes real effort. That is a skill, and it is not the skill you developed qualifying.

The second is when the site needs to connect to something. A site that captures an enquiry, qualifies it, routes it into a CRM, books a call, and triggers an onboarding sequence is a different piece of infrastructure to a brochure with a contact form. Wiring that together properly is where most DIY builds stall.

The third is when you have already tried. If you have a site you built two years ago that has produced almost nothing, the honest read is that the constraint is not budget.

Niall at OD Accountants had his site rebuilt around conversion rather than content. Monthly visitors went up four times over, with ten to fifteen enquiries in the first month after launch and three new clients from them.

Several software vendors sell websites built specifically for accounting firms, usually bundled with a client portal and a document exchange. The subscription sits well above a general-purpose builder.

The trade is speed for distinctiveness. You get a compliant, professional site quickly, with the sector-standard pages already written. You also get a site that looks like several hundred other firms using the same template, with limited scope to build the page structure that a positioning strategy requires.

For a firm that wants a credible online presence and gets its clients through referral, that trade is reasonable. The site is there to reassure someone who has already been given your name, and it does that job.

For a firm trying to generate demand from search, the template constraint becomes a ceiling. You cannot build twenty niche landing pages if the system allows six page types. We have moved firms off these platforms for exactly that reason, usually about a year after they realised the site was doing nothing beyond looking respectable.

One practical point either way. Make sure you can export your content and that you own your domain outright. Some bundled arrangements make leaving harder than it should be.

Run through four questions honestly.

• Who is named as owner of the website after launch, and how many hours a month do they have for it? If the answer is nobody, resolve that before choosing a platform.
• Is the site meant to reassure referrals or generate enquiries? Reassurance is a design problem. Generation is a structure and content problem, and they need different budgets.
• Do you already know which client type you want more of? If you do not, a bigger website spend will produce a bigger, vaguer website. Positioning comes first.
• What happens to an enquiry at 7pm on a Thursday? If the answer is that it sits in an inbox until Monday, fix the follow-up before you fix the site.

If DIY comes out ahead, use whichever mainstream builder your nominated owner finds easiest to edit. That is a genuine criterion, not a soft one. If the honest answers point the other way, you are buying a system rather than a website, and the brief should be written accordingly.
