The verdict in three sentences
In 2026, an accounting firm website costs between 3,500 and 10,000 EUR depending on service pages, the client portal and interactive simulators. The site is not a brochure but a magnet for founders and small businesses: those searching "accountant for freelancer" or "which company structure" land on a firm that answers their questions. Simulators (payroll charges, VAT, legal structure) are the best generators of qualified enquiries.

What turns a visitor into an enquiry
Service pages must speak to intent: "business incorporation support", "small-business payroll", "tax optimisation". Each captures a query. Simulators — social charges, choosing between structures, VAT estimate — offer immediate value and collect the prospect's email. The client portal (document upload, invoices, messaging) is a retention and modernity argument. Tax SEO content, refreshed at each finance law, ranks the firm on dozens of queries founders type before choosing an accountant.
Mini case study
Ferrand & Partners, three accountants in Bordeaux, invests 7,000 EUR in the "Acquisition firm" package with five service pages, a structure-choice simulator and a tax blog. Before, the firm received almost no web contacts. Six months later, the "which structure" simulator and SEO on "accountant business creation Bordeaux" generate 12 enquiries a month, of which 5 become recurring clients at an average fee of 2,400 EUR per year. That is 12,000 EUR of added recurring annual billing in the first half-year: the site pays off in under a month of signed engagement.
