What an Accountancy Firm Website Costs, and What It Needs

en 2026-09-14 7 min read

An accountancy firm website costs EUR 1.500 to 3.500. That is step 03: four to seven pages, a CMS you can edit, a page for each service you sell, and a contact or booking flow that captures the enquiry properly. A practice that needs only a credible presence sits below at EUR 900 to 1.500. A firm whose clients log in and exchange documents sits above at EUR 3.500 to 7.500. All figures exclude VAT.

The steps, and what a firm gets at each one

These are ranges, not anchors. Where you land inside one depends on how much exists before we start. Full inclusions are on packages.

What an accountancy site has to do

A page for each service

Bookkeeping, payroll, VAT returns, annual accounts, corporate tax and advisory are separate purchases, and people search for them separately. A single Services page listing all of them competes for none, because it answers none of them in depth. Each service gets a page: who it is for, what is included, what you need from the client to start, and how the fee is arrived at. That is the bulk of the four to seven pages at step 03.

Saying something honest about fees

Buyers ask the price question early. You do not have to publish a fixed fee to answer it. Publish what drives it: transaction volume, payroll headcount, entity type, VAT filing frequency, whether the bookkeeping arrives sorted or in a carrier bag. A page explaining the shape of a fee, with a starting figure and an honest sentence about what raises it, does more work than a button labelled request a quote.

The onboarding form is the real product

When a prospect says yes, you need company details, the chamber of commerce number, the VAT number, UBO information, identity documents, and access to wherever the books currently live. Over scattered email that drags, and the client forms an opinion of the firm during exactly that stretch. A structured onboarding form with file upload and a clean handoff into your inbox or practice management tool removes the most manual handling of any single piece here. It fits inside step 03, as long as the client needs no account to return to it.

Seasonal demand

Traffic is not flat across the year: filing deadlines pull enquiries into narrow windows, and the firm already visible when one opens takes them. So do not start a build in the month you need it live: the week ranges above are build time, and content collection happens before them.

Where a portal pushes it to step 04

Step 03 covers a site where every page is public and every form ends in an email or a CRM record. Step 04 begins the moment a client needs to log in.

A portal means accounts and resets, permissions so no client sees another client's folder, an upload area, and a record of who sent what and when. It is a small application wearing a website, and EUR 3.500 to 7.500 is what that costs. Other things open the same door:

• Taking payment. Card payment for a fixed-fee package, a deposit before onboarding, an invoice settled from the site. Payments are step 04 in a new build and an add-on at EUR 600 to 1.500 on a site you already have.
• A live connection to your practice software. Reading client data out of it, or writing enquiries into it through an API, is integration work and lives at step 04.
• A chatbot answering from your own intake rules rather than a widget you paste in.

If you do not need any of it, do not buy it. A portal nobody logs into is the most expensive thing on this page. How we draw that line is on design and engineering.

What moves the quote

• How much already exists. Written service copy, a usable logo, photography of the actual people. Everything you bring is work nobody has to do twice.
• Whether it needs accounts and payments. The step 03 to step 04 line, and the biggest single mover here.
• How many languages. A Dutch and English site is a second set of content and a second set of URLs, not one site shown twice.
• What happens after launch. Whether we hand over the keys and step back, or keep the site maintained.

A fixed quote always follows scoping.

Process and timeline

1. Scoping. The step, the page list, the forms, and what connects to what.
2. Content. Service copy and the fee explanation. This is where projects wait, because it needs a partner's judgement rather than a designer's afternoon.
3. Design and build. 2-3 weeks at step 02, 3-6 weeks at step 03, 6-12 weeks at step 04, from the point the content is settled.
4. Review and launch. Test the forms with real submissions, on a phone. A form that fails silently is worse than no form.

After launch

Care is EUR 100 to 300 per month: updates, monitoring, backups, small fixes. Not redesign and not new features, so a service page template that did not exist before is new work with its own quote.

Search is priced separately. An SEO foundation is EUR 450 to 750, paid once: Search Console and analytics configured properly, indexation, technical hygiene, titles, internal links, and a written plan covering the next three to six months. Ongoing work is the other line, SEO growth at EUR 500 to 800 per month.

You own the code, the repository and the database. We can host, but that is agreed per customer rather than assumed.

When to spend less

If the firm is at capacity and new clients arrive by referral, a step 03 build is not what you are missing. A referred prospect checks that you exist, look credible and answer the phone, and a step 01 landing page at EUR 600 to 900 does that. A new practice testing a niche should do the same: one page, and let the enquiries decide whether more pages are worth paying for. If your current site is sound and only the writing is stale, that is a content job, not a rebuild.

Questions buyers actually ask

Do we need a client portal, or is a form enough?

A form is enough when documents arrive once, at onboarding, and the relationship afterwards runs on email and whatever client access your accounting software already gives you. A portal earns its keep when documents arrive all year, or when you need a defensible record of what arrived and when.

Can we start at step 02 and grow into step 03 later?

Yes, and it can be the right call. The condition is that the smaller site sits on the same foundation rather than on something disposable, so service pages added later are add-ons with their own quote, not a rebuild.

How much writing do we have to do ourselves?

Less than you fear, more than nothing. We can draft every page, but the fee logic and the specifics of how you work have to come from a partner. Expect real attention on the fee page and the service pages, very little elsewhere.

Can you connect the site to our practice management software?

If it exposes an API, yes: step 04 in a new build, because it becomes two systems that have to agree, or the CRM or API integration add-on at EUR 750 to 2.500 on a site you already have. Tell us which software at scoping; it changes the quote more than the page count does. The stack we build on is described on our Next.js development page.

Tell us which services you sell and whether clients need to log in, and you get a fixed quote against the step that fits. Start here.
