The verdict in three sentences
A Chicago accounting practice should budget 6,000 to 15,000 USD for a solid entry site and 18,000 to 45,000 USD for a full tier with portal and content, depending on how many service lines it markets. The portal and booking modules usually pay for themselves faster than the design upgrade, because they cut admin time during tax season. Ask every vendor for a tier sheet listing pages, modules and annual costs in writing.
The pricing grid by tier
The figures below are 2026 market estimates for the Chicago area. Prospects want to see CPA licensing with the Illinois Department of Financial and Professional Regulation, AICPA membership and peer review status, so trust signals are part of every tier.
| Tier | Price (2026 estimate) | Pages | Timeline | What is included |
|---|---|---|---|---|
| Essential | 6,000 to 15,000 USD | 5 to 8 | 4 to 6 weeks | Home, firm, services, team bios with CPA credentials, contact |
| Professional | 15,000 to 28,000 USD | 12 to 20 | 6 to 10 weeks | Service pages by niche, tax season hub, blog, analytics |
| Premium | 28,000 to 45,000 USD | 20 plus | 10 to 14 weeks | Custom design, SEO, portal integration, accessibility audit |
| Packaged option (Kolonell Starter) | 610 to 1,145 EUR | 5 | 7 to 10 business days | Mobile site, contact form, ideal for a new small practice |
Many firms overspend on design and underspend on the tax season hub, the page cluster that captures most enquiries between January and April.
Modules worth adding
Clients choose accountants on trust and convenience. Two modules matter most to CFOs and small business owners.
| Module | Price (2026 estimate) | Extra time | Why it matters |
|---|---|---|---|
| Online booking | 1,500 to 3,500 USD | 1 week | Fewer calls in peak season |
| Secure client portal (document upload) | 5,000 to 12,000 USD or SaaS subscription | 2 to 4 weeks | Replaces email attachments, audit trail |
| Quote request by service type | 800 to 2,000 USD | 3 days | Qualifies leads before the call |
| Spanish version | 15 to 30 percent of site cost | 1 to 2 weeks | Large Spanish speaking business community |
| Online fee payment | 1,000 to 3,000 USD | 1 week | Faster collections |
If you already use a practice management suite with a built in portal, integrate it instead of building one. A secure link and single sign on often cost a third of a custom portal.
Recurring costs
| Recurring item | Annual cost (2026 estimate) |
|---|---|
| Maintenance and updates | 1,800 to 6,000 USD |
| Hosting with backups | 300 to 1,200 USD |
| Portal or booking subscription | 600 to 3,600 USD |
| Accessibility monitoring | 500 to 2,000 USD |
| Content refresh for tax law changes | 1,000 to 4,000 USD |
Expect 4,200 to 16,800 USD a year to run a firm site with a portal, a fraction of one staff accountant's salary.

Illustrative example, not a real client: Megan, managing partner of a 10 person CPA firm in the Loop, serves 300 small business clients. She picks a Professional tier at 22,000 USD, booking at 2,500 USD and a portal integration at 4,000 USD, for 28,500 USD. Her staff spend 10 hours a week chasing documents in peak months; the portal saves 6, so 24 hours a month at 45 USD of loaded cost, 1,080 USD a month. Over four tax season months plus lighter savings the rest of the year, the build pays back in about two years.
FAQ
How much does a CPA firm website cost in Chicago in 2026?
Roughly 6,000 to 45,000 USD depending on tier. Booking and portal modules add 1,500 to 15,500 USD.
Should we build or buy a client portal?
Buy or integrate if your practice software already offers one, which often costs 50 to 300 USD a month. Build only for unusual workflows, at 5,000 to 12,000 USD.
Which trust signals matter most?
CPA licensing details, AICPA membership and peer review status, plus clear bios. Firms that show credentials prominently often see form conversion rise by 1 to 2 points.
How long does a launch take?
Four to six weeks for an Essential tier, up to 14 weeks for Premium. Start by September if you want the site live before tax season.
Is accessibility required for an accounting site?
It is strongly advised under ADA case law, and WCAG 2.1 AA is the reference. Retrofitting later costs 3,000 to 10,000 USD.
