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 11 firms that say they do catch-up or cleanup work. On process, 19 of 65 give a reporting schedule and 15 explain onboarding.
Software and remote work
QuickBooks is the software named most, by 26 of 65 firms, ahead of QuickBooks Online 20% and Xero 11%. 22 of 65 say they work with clients remotely, so a firm across the metro can still take you on.
Licenses and public records
