The verdict in three sentences
An accounting firm website in Toronto costs in 2026 between 5,000 and 12,000 EUR depending on whether it includes a fee simulator, a secure client portal and tax SEO content. The lead qualification form lifts enquiries by +25%, the client portal adds 2,500 to 4,000 EUR, and maintenance sits at 150-350 EUR/month. Budget 5 to 8 weeks for delivery.
The breakdown of an accounting firm budget
An accounting firm site converts on trust and qualification: simulator, tax content and client portal. Structure of an 8,000 EUR budget in 2026.
| Line item | Share | Range EUR | Detail |
|---|---|---|---|
| Scoping & UX | 12% | 600 - 960 | Workshops, client journey |
| Professional UI design | 20% | 1,000 - 1,600 | Brand, service pages |
| Next.js development | 28% | 1,400 - 2,240 | Front, responsive, perf |
| Fee simulator | 12% | 600 - 960 | Interactive calculator |
| Secure client portal | 18% | 2,500 - 4,000 | Auth, document handling |
| Tax SEO content | 10% | 500 - 800 | Articles, schema |
The secure client portal is the heaviest line (up to 4,000 EUR) as it involves authentication, document management and data-protection compliance; it is also the main retention driver.
Options and 2-year cost of ownership
An accountant reasons in return on investment. 2026 orders of magnitude for a firm's site.
| Line item | Basic site | Full site |
|---|---|---|
| Design & development | 5,000 EUR | 12,000 EUR |
| Fee simulator | No | Included |
| Secure client portal | No | Included |
| Qualification form | Included | Included + scoring |
| Maintenance (per month) | 150 EUR | 350 EUR |
| Total cost over 2 years | 8,600 EUR | 20,400 EUR |
| Estimated qualified leads/month | 10 | 18 |
The full site doubles the cost but lifts qualified leads by +80% thanks to the simulator and qualification: for a firm, each new recurring client is worth several thousand euros of annual fees.
Mini case study
Sophie, partner at a 12-person accounting firm in Toronto, invests in a full site. Budget agreed: 9,500 EUR, 7 weeks, with a fee simulator and client portal. Before, the firm received 10 enquiries a month via a generic form, converting at 20%. After, the qualification form and simulator lift enquiries to 13 a month (+30%) with conversion improved to 28% thanks to pre-screening. That is roughly 2 extra recurring clients a month; at an average annual fee of 2,400 EUR, those clients generate 57,600 EUR of additional recurring revenue over 12 months: the site pays back in under 3 months.

FAQ
Is the fee simulator worth its cost?
Yes: it pre-qualifies the prospect and sets a price expectation, cutting fruitless meetings. For 600-960 EUR, it markedly improves inbound lead quality.
Why does the client portal cost up to 4,000 EUR?
Because it involves secure authentication, confidential document exchange and data-protection compliance. It is a retention investment: a client who uploads documents online stays longer.
Does the qualification form really lift enquiries by +25%?
Yes as an order of magnitude: by guiding the prospect (sector, size, need), it lowers friction and improves completion. The gain shows in both volume and quality.
What maintenance budget should I plan?
Between 150 and 350 EUR/month depending on features: security, backups, regulatory updates to tax content and the client portal. Essential given data sensitivity.
How long to deliver?
5 to 8 weeks in 2026. The secure client portal and simulator slightly extend the timeline versus a plain corporate site.
