Where another tool is the better choice
- Digits includes bill pay, invoicing and iPhone and iPad apps on every plan, and its security page states a SOC 2 Type II report. Accountable sends invoices and tracks bills, but you pay bills from your own bank, and its SOC 2 audit is still planned.
- Pilot and Zeni put a person on your books and sell tax and finance work. Accountable is software, and it does not file taxes.
- Xero costs $177 a month for 3 companies against Accountable's $198, and includes unlimited users on every plan.
- QuickBooks is what many US CPAs already know. If yours insists on it, send them Accountable's general ledger and statements, which every plan exports.
- Kick Basic is $40 a month for one company, less than Accountable's $149 Pro plan.
