What the evidence shows

Pricing

5 of 51 firms here publish a price or a starting price, 4 say they quote, and 42 say nothing about fees (82%). Figures the firms publish themselves, as their sites word them: Catalyst CPA ("From $295/mo"), ThinkForward Bookkeeping Services ("$250/month") and Rancho Bookkeeping ("$350 - $400 per month"). Get the monthly fee, the transaction volume it assumes and what counts as extra in writing.

Services and process

If you're behind, start with the 8 firms that say they do catch-up or cleanup work. On process, 13 of 51 give a reporting schedule and 8 explain onboarding.

Software and remote work

QuickBooks is the software named most, by 18 of 51 firms, ahead of QuickBooks Online 20% and Xero 12%. 19 of 51 say they work with clients remotely, so a firm across the metro can still take you on.

Licenses and public records

Because California publishes its records as open data, the checks for this group found 15 firms with an active CPA license or permit on California's published register. Check any CPA claim yourself on the California Board of Accountancy lookup.

The ranking

The numbered firms score between 23 and 73; the median across every scored firm is 26. 19 more firms reached 70% coverage with fewer than 6 documented items, so they sit under the list as Also scored, without a number. The top of the list: Catalyst CPA (73 at 73% coverage), ThinkForward Bookkeeping Services (54 at 74% coverage) and QuickFiscal (47 at 77% coverage). Corona has the most numbered firms (4), and the list spans 14 towns in all. A high-coverage firm with a modest score isn't a weak firm. Its site simply leaves more for you to ask.
