How to price bookkeeping services

A bookkeeping price is not a number a firm picks from a list. It is the result of the work the client needs, the time and tools that work takes and the margin the firm needs to stay open. A price built on scope is easier to explain and easier to renew than a price built on a competitor's website.

Key takeaways

  • Define the scope before you name a price.
  • Calculate the cost to serve, including the software and the review time.
  • Choose a model the client can understand and the firm can renew.
  • Write down what is not included.
  • Raise the price with the scope and the notice, not with an apology.

Start with the scope

A monthly bookkeeping engagement can mean very different things: transaction entry, a full close, reconciliations, sales tax, payroll, invoicing, reporting and advisory. Write down what the firm will do each month and what the client will send.

The scope should also name the number of accounts, the transaction volume, the number of employees and the reporting package. A client with three bank accounts and 100 transactions is not the same as a client with six accounts and 1,000 transactions.

Calculate the cost to serve

Add the staff time for the work, the review time, the software subscription, the document collection tool and the overhead the engagement consumes. Include the time spent chasing missing documents and answering questions, even if the firm does not bill for it separately.

A simple estimate is the hours per month multiplied by the fully loaded hourly cost, plus the direct software cost. If the result is higher than the price the firm has in mind, the scope or the process needs to change before the price does.

Choose a pricing model

A fixed monthly fee is easy for the client to budget and easy for the firm to renew. An hourly rate is useful for cleanup, advisory or work with an unclear scope. A value-based fee works when the firm can show the client a specific outcome, such as a clean set of books for a lender.

Many firms use a fixed monthly fee for the recurring close and a separate project fee for onboarding, cleanup or a backlog. Keep the two separate so the recurring price reflects the ongoing work.

Write down what is not included

The engagement letter should list the exclusions: payroll, sales tax, audit support, catch-up work, a new entity, a new location and extra reporting. Each exclusion should say how the firm will price the work if the client needs it.

An exclusion is not a threat. It is a way to keep the monthly fee honest and to give the client a clear decision when the scope changes.

Present the price with the scope

Show the client the scope, the deliverables, the due dates and the price together. A price without the scope invites a comparison with a cheaper firm that is doing less work.

If the client asks for a lower price, reduce the scope rather than the margin. Fewer accounts, a later due date or a smaller reporting package can lower the price without making the work unprofitable.

Raise the price on purpose

Review the price at least once a year against the actual hours and the software cost. If the work has grown, the price should grow with it. Give the client notice as the engagement letter requires, and explain the change with the scope and the service, not with an apology.

A price increase is easier when the firm has a record of what it delivered. The close report, the review notes and the response time are the evidence that the fee is connected to the work.

Questions about this guide

Should a bookkeeping firm charge hourly or a fixed monthly fee?

A fixed monthly fee fits a recurring close with a stable scope. Hourly pricing fits cleanup, advisory or work whose scope is not clear. Many firms use both, with a fixed fee for the close and a project fee for the rest.

What should the monthly fee include?

The recurring work the firm has agreed to do, such as transaction entry, reconciliations, the close, the reports and the document request. Payroll, sales tax, cleanup and audit support are usually separate unless the engagement says otherwise.

How often should the firm raise prices?

Review the price at least once a year and when the scope changes. The engagement letter should state the notice period and how the firm communicates a change.
