Is AI Making Billable Hours Obsolete for Accounting Firms?
If AI can turn 40 hours of accounting work into 30 minutes, what exactly should the client pay for?
That’s a question accounting firms are going to have to answer.
Last week, I talked about billable hours, productivity ratios, and profitability. This week, I’m taking that conversation a step further. What happens when technology dramatically reduces the amount of time required to complete the work?
If your pricing model is based on hours, greater efficiency could actually mean less revenue. That’s one reason I think accounting firms should seriously consider value pricing, flat-rate pricing, or another model that focuses more on the work being delivered than the number of hours it takes to deliver it.
AI Is Changing the Billable-Hour Equation
I recently talked about a CPA who used Claude to complete work in about 30 minutes that could previously have taken his staff approximately 40 hours.
The client still received the work. The expertise behind it still mattered. The CPA still had to make sure the result was accurate.
But if you’re billing strictly by the hour, what happens to those other 39 1/2 hours?
Do you charge for 40 hours because that’s what the work used to take? Do you charge for 30 minutes because that’s how long it takes now? Or do you decide what the work itself is worth to the client?
AI is making that question much harder to avoid. I’ve talked previously about how AI is already changing accounting, bookkeeping, tax, and advisory work. As repetitive tasks become faster, firms need to think differently about what clients are really paying for.
Clients Don’t Want to Watch the Clock
One of the frustrations I hear from business owners is that they hesitate to call their CPA because they don’t know what the call will cost.
A short question can turn into a charge they weren’t expecting. Then the client starts watching the clock rather than focusing on getting the help they need.
Value pricing changes that conversation.
If clients know what their accounting, bookkeeping, tax preparation, and financial review services are going to cost each month, they can budget for them. They aren’t wondering what the next invoice will look like, and they may be more comfortable calling you before a small financial issue turns into a larger one.
I’ve Seen This Pricing Change Before
This isn’t a completely new idea for me.
I helped introduce flat-rate pricing to contractors beginning in the late 1980s. At the time, many contractors were billing based on time and materials.
That created a basic fairness problem. If one technician needed two hours to complete a repair that another technician could complete in one hour, why should the customer pay more for the slower technician?
Flat-rate pricing changed the focus from how long the technician was standing in the customer’s home to the value of completing the repair.
I see a very similar question developing in accounting today.
Your Firm Still Has to Be Profitable
Moving away from billable hours doesn’t mean ignoring profitability.
The pricing has to work for everyone. Your client needs to feel they’re receiving good value, and your firm still needs to generate the profit required to operate and grow.
One place to start is with your existing numbers.
Look at a longer period, preferably a full year. Determine your total profit and the number of billable hours that produced that profit. Divide the profit by the billable hours and calculate how much net profit each billable hour has historically generated.
That gives you a financial starting point as you begin thinking about value pricing.
This isn’t about guessing what to charge. It’s about knowing what your current pricing model actually produces before replacing it.
Value Pricing Can Change the Client Relationship
Predictable pricing can also make financial advisory services easier to provide.
Instead of sending financial statements that clients may never really study, you can build regular financial reviews into the relationship and help them understand what’s happening in their businesses.
Graphs can make those conversations much easier. When a business owner can see revenue, profitability, cash flow, productivity, and other financial trends visually, the numbers become much easier to understand.
That’s also where Financially Fit Business can support financial professionals. You can turn client financial statements into clear trend graphs and use them to have more useful financial conversations.
What Happens to Team Productivity?
There’s another side to this that accounting firms need to think about.
If you’re no longer charging clients primarily for hours, do you still manage employees primarily around hours?
Suppose one team member can accurately complete all of the assigned client work in half the time it takes someone else. The clients are taken care of. The work is accurate. The firm is profitable.
Should that employee be penalized for being more efficient by simply being given another 20 hours of work?
Some firms are starting to think differently about that too, including whether certain work can be managed around completed tasks and results rather than simply time at a desk.
It’s a very different mindset, particularly in a profession that has spent decades measuring productivity through hours. But AI is going to force more firms to have the conversation.
You Don’t Have to Change Everything at Once
Try it.
Choose one or two clients who might be receptive to predictable value pricing. Determine what you’re currently earning from the relationship, decide what services will be included, establish a price that protects your profitability, and test the model.
Then watch what happens.
Are the clients happier? Are billing conversations reduced? Are they calling you more often when they have questions? Is your team more efficient? Does the relationship remain profitable?
You don’t have to completely eliminate billable hours tomorrow. But I do think you need to start asking whether billing by time still makes sense as technology continues to change how quickly the work gets done.
Help Your Clients See the Value Beyond the Hours
The real opportunity isn’t simply replacing one pricing model with another. It’s shifting the conversation toward the financial insight, judgment, and guidance you provide.
Common Questions About AI, Billable Hours and Value Pricing
Why is AI creating problems for accounting firms that bill by the hour?
AI can dramatically reduce the time required to complete some repetitive accounting tasks. If a firm’s revenue depends primarily on hours worked, becoming more efficient can reduce billable hours even though the client still receives the completed work and professional oversight.
What is value pricing for an accounting firm?
Value pricing focuses on the service and value being provided rather than billing the client strictly for the time required to complete it. It can also give clients a more predictable cost for accounting, tax, bookkeeping, and advisory services.
How can an accounting firm begin setting value-based prices?
Start by understanding what your current billable-hour model produces. Review a full year of profit and billable hours and calculate the net profit generated per billable hour. That gives you a financial baseline when developing a different pricing structure.
How does value pricing benefit accounting clients?
Predictable pricing can reduce surprise invoices and make services easier to budget. Clients may also be more comfortable asking questions when they know a short conversation won’t automatically create an additional bill.
Should an accounting firm test value pricing before adopting it firm-wide?
Yes. Start with one or two appropriate clients. Define the services included, establish pricing that protects profitability, and evaluate the effect on client satisfaction, team efficiency, billing conversations, and firm profitability.
