AI for accounting and CPA firms in Toronto and the GTA

Custom Solutions AI helps accounting and CPA firms in Toronto, Richmond Hill and across the GTA use AI where it pays off first: answering every call in tax season, following up every enquiry, and showing up when a business owner searches for an accountant on Google, in Google Maps or in an AI answer.

The short answer

AI doesn’t do your clients’ taxes. It takes the front-office load off your team: calls, intake, reminders and follow-up. Your accountants spend their hours on billable work, and no enquiry goes unanswered because everyone was busy.

Where AI pays off first for accounting firms

  • Tax season phones. From February to the April 30 filing deadline, and June 15 for self-employed clients, the phone rings more than any front desk can answer. An AI receptionist answers every call in seconds, books consultations and logs a full transcript, so nothing gets lost.
  • Enquiry follow-up. A business owner who emails three firms usually hires the one that replies first. AI follow-up replies in minutes and keeps going until they book or say no.
  • Reminders. Automated reminders for missing slips, signatures and deadlines, so your team stops chasing them one email at a time.
  • Getting found. When a business owner in Markham asks Google or ChatGPT for a corporate tax accountant nearby, the firms with a complete Google Business Profile, recent reviews and a clear page for each service come up first. That is our SEO, AEO and GEO work.
  • A website that converts. The gaps we see most on accounting firm websites: a phone number that can’t be tapped on a phone, no enquiry form, slow pages on mobile, and every service crammed onto one page. A site rebuilt to convert fixes all four.

What we don’t automate

Professional judgment stays with your CPAs. AI doesn’t prepare or file returns, give tax advice or sign anything. It handles the work around the work: answering, booking, reminding and following up.

Your clients’ information

Accounting firms hold some of the most sensitive personal information there is. Under PIPEDA, Canada’s private-sector privacy law, your firm stays accountable for personal information it hands to a service provider. So ask any AI vendor, including us, where client data is stored, who can see it and how it is deleted, before anything is switched on.
