What the evidence shows
Pricing
Pricing is where these sites say least: 13 of 18 are silent on fees, 3 say they quote each job, and 1 publish a monthly figure. Figures the firms publish themselves, as their sites word them: Apple Bookkeeping & Tax Services ("$150 / Month"). A written scope with the fee and its limits is the thing to ask for on a first call.
Services and process
If you're behind, start with the 4 firms that say they do catch-up or cleanup work. On this page that's Twin Oaks Bookkeeping LLC, Affinity Bookkeeping Plus LLC, Better Bookkeeping, LLC and JKL Bookkeeping LLC. On process, 9 of 18 give a reporting schedule and 4 explain onboarding. Nationally 24% of listed firms name a reporting schedule, so this group is above the norm.
Software and remote work
QuickBooks leads the software firms here name (56%); after it come QuickBooks Online 11% and ADP 6%. Remote work is stated by 7 of 18; the filter above the list narrows to them.
Licenses and public records
There's no New Hampshire open data for us to match licenses or registrations against, which is why so few firms here reach 70% coverage. A website on its own can't get a firm there. A few were looked up by hand on the New Hampshire Board of Accountancy, and the CPA records found belong to Blackforest Advisors PLLC and GrottLuker & Co.. Median evidence coverage here is 87.5%. Any firm that says it's a CPA practice can be checked on the New Hampshire Board of Accountancy lookup.
The ranking
Numbered scores on this list run from 72 down to 30, and the median across every scored firm is 45. The top of the list: Twin Oaks Bookkeeping LLC (72 at 89% coverage), Affinity Bookkeeping Plus LLC (62 at 86% coverage) and StarSail (60 at 92% coverage). Portsmouth has the most numbered firms (5), and the list spans 9 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.
