Hourly billing is the traditional and most straightforward way bookkeepers charge: you set your rate per hour based on your fixed costs and desired profit margin, then, however many hours it takes you to complete the work, that's the fee.

On average, bookkeepers may charge anywhere from $95 to $175 per month, although this can be higher in major cities or for those with specialized non-profit expertise. Some might offer fixed monthly rates, particularly if they provide consistent services.

In the realm of accounting, outsourcing bookkeeping tasks to external service providers, has emerged as a viable solution for many CPA Firms. Outsourced bookkeeping services cost up to $100 per hour or $500 to $5,000 monthly for your accounting firm.
