Tax season triples call volume for twelve weeks, then it falls away. Pay for the peak, not the year.
Short answer: 5 vendors in our dataset name accountants on their own site. 5 publish a fixed monthly price, from US$29/mo (Dialzara); Smith.ai also has a free tier. 0 are usage-based or quote-only.

A vendor is listed only if its own website names accountants as an industry it serves. The source page is linked in the table. We did not test industry-specific features.
What should I ask before signing?
