Who this tool is for
Owners comparing a DIY bookkeeping stack, software with outside help, or a managed bookkeeping service on the same monthly basis.
The calculator separates software, users, payment processing, and service support because those costs behave differently. Invoice volume is recorded as a workload signal rather than added directly to the total: providers price invoicing in different ways, and processing cost depends on payment method and sales value.
Use regular renewal pricing from a written quote. Add the cost of the people and add-ons actually required to keep the books reviewable, then compare the estimate with the time and cleanup risk that remains with the owner.
Use the tool
Run the workflow in this order
- Collect the regular software price and included-user limit.
- Estimate paid seats, payment fees, payroll or app add-ons, and recurring bookkeeping support.
- Record monthly invoice volume so vendors can confirm plan and workflow capacity.
- Run a low, expected, and high scenario instead of relying on one total.
- Save the quote date, billing cycle, exclusions, and cancellation terms beside the estimate.
Evidence to collect
| Review area | Evidence to retain or verify |
|---|---|
| Subscription | Written renewal price, billing cycle, included users, and plan limits |
| Transactions | Invoice volume, payment mix, processor fee schedule, and deposit timing |
| Support | Bookkeeper scope, response boundaries, cleanup exclusions, and meeting cadence |
| Exit | Export formats, attachment access, final data availability, and cancellation terms |
How to interpret the result
The result is an operating-cost estimate, not a quote. A lower number is only preferable when both options cover the same users, accounts, payments, reporting, and professional-review needs.
If managed service cost appears high, compare it with a realistic DIY scenario that includes software, owner time, month-end review, and expected cleanup. If the inputs are uncertain, keep the range visible instead of forcing a precise result.
This tool is educational software and workflow research. It is not bookkeeping, accounting, tax, legal, payroll, compliance, or financial advice.
