Billing for work AI sped up: let waiting work pick a rate cut or fixed fee
Bill for work AI has sped up by whether waiting work can fill the freed time, not by the size of the speed-up.
Key points
- Is work waiting? That decides, not speed
- Rate cut or fixed fee: cut if work waits
- Handoff and checks stay. Price them in
- Write the client note with the decision

The deciding factor is waiting work, not the speed-up
A&A perspective
When AI shortens the work on a deliverable you have always quoted by the hour, how to bill for it is settled not by how many hours turned into how many minutes but by whether you already have work in hand to fill the freed time. In this article, waiting work means jobs you could start as soon as your hands are free.
A&A perspective
Quotes you turned down, inquiries you have left unanswered, and clients you have kept waiting all count.
A&A perspective
Automate & Augment (A&A), which rebuilds operations around AI and takes the work through to implementation, took its cue for this way of deciding from two overseas cases.
From the sources
One of the customer stories Anthropic has published describes Layer, a 25-person advertising agency in Norway.
From the sources
Layer produced a report that pulled numbers from five different sources. It quoted its client 10 hours of billable work for one report, billed by the hour. Once it used MCP, a connector that lets Claude read data from ad platforms directly, the case study says the report came to take 20 minutes.
From the sources
The other case is EvenUp, which builds document-drafting AI for US law firms that handle personal injury cases. Before EvenUp, those firms drafted the documents by hand, at 8 to 15 hours per case, and the case study says they were left with two options: take the case and absorb the hours, or refer it out to another firm.
From the sources
With EvenUp, the case study says, this drafting shrank from hours to minutes. One firm that adopted it had a 45-day backlog of cases. What the case study reports as the result is not a lower price but that the number of demand letters the firms sent out tripled, and that the backlog was cleared.
A&A perspective
A&A reads the two cases this way. On Layer's side, the very hours it billed against disappeared. Layer's case study does not say that work was waiting to fill the freed time.
A&A perspective
On EvenUp's side, cases were already queued, so the freed time went straight into the next job. What separated the two was not the size of the speed-up but whether the work was there first.
A&A perspective
Neither case study says anything about how to set prices, though. The figures are self-reported by the AI provider and the companies that adopted it, with no case count and no time period. Tripled output and a 45-day backlog are not numbers you can use for your own forecast. All this article borrows from the cases is one distinction: after a speed-up, you are in one of two situations.
Cut the rate if work is waiting; if not, move to a fixed fee per deliverable
A&A perspective
If you have waiting work, you can lower your rate and make it back on volume. If you keep billing by the hour without it, every gain in efficiency shrinks your revenue. When there is no waiting work, what you change is not the price but the unit you bill in.
A&A perspective
A fixed fee per deliverable sets a price and an acceptance standard for each deliverable rather than for the hours worked. Once the unit is the deliverable, the bill does not move when the work gets faster.
A&A perspective
There are four billing options. Waiting work decides between two of them: a rate cut and a fixed fee. The other two depend on different conditions, but they sit in the same table. All four are A&A's own design, not something drawn from the sources.
From the sources
Widening the deliverable has a close real example. At Layer, the case study says, annual media plans, once too time-consuming to build thoroughly, are now standard practice. The case study does not say whether those plans were billed separately.
A&A perspective
A&A reads this as freed time flowing into a deliverable that could not be made before.
A&A perspective
A&A sees keeping quiet as usable only as a stopgap. Once you have quoted on the basis of hours, the client will eventually see that the basis is gone. If you have no explanation when they do, every bill you sent before may come into question.
A&A perspective
If you choose the rate cut, how to read the economics after the cut is covered in a separate article, “Low-ticket service profit rests on human touches, not AI speed.”
| Billing option | Choose it when | Do not choose it when |
|---|---|---|
| Lower the hourly rate | Turned-down work has piled up, and a lower rate would let you take on more jobs | Inquiries are not yet steady |
| Keep the price, widen the deliverable | The client clearly wants something more | You have not checked with the client what to add |
| Switch to a fixed fee per deliverable | The deliverable has a set form and its acceptance standard can be written down | Specs change every time and the workload cannot be predicted |
| Change nothing and keep quiet | Only as a stopgap until the next quote | The client could spot the speed-up first, and you have no explanation ready |
Handoff and checks remain after the speed-up, so keep them in the price
A&A perspective
Whichever option you choose, include the time for handoff and checking in the price. What AI mainly sped up is the making. Handing the work over and having a person check it are still there.
From the sources
In Layer's case, 17 of the 20 minutes go into moving the finished data into the client's spreadsheet. The case study also says that, before rolling it out to clients, a Layer strategist spent weeks validating the AI's output.
From the sources
A wrong number in a client report is expensive, Layer's case study says, because someone spends real budget on it. EvenUp's case study likewise says every draft still ends with a person: an attorney reads, checks and signs it.
A&A perspective
A&A reads this as where the split between people and AI falls. The making can go to AI, but fitting the work to the client's format and checking it while carrying responsibility for errors still sit with people. Price only the making, and those two steps become unpaid work.
Hypothetical example
Take a hypothetical. A four-person research firm quotes a client's monthly report as half a day of work and bills it at an hourly rate. With AI, the part that produces the report now takes 20 minutes. This 20 minutes is a made-up figure, separate from Layer's case.
Hypothetical example
But when the firm times checking the numbers, pouring them into the client's format and rereading before sending, those come to 90 minutes in total. Half a day did not become 20 minutes; it actually became just under two hours.
Hypothetical example
Next, the firm counts the quotes it turned down in the past three months because it could not meet the deadline, and the inquiries it has left unanswered. Both come to zero. With no waiting work, a rate cut is off the table. The firm switches to a fixed fee per report, based on the just-under-two hours that include checking and handoff.
Hypothetical example
Had it turned down three jobs, lowering the rate to win more of them would also have been an option.
Write the client note at the same time you decide how to bill
A&A perspective
Whichever of the four you choose, write the note to the client at the same time as you decide the billing form. If you leave it for later and the client notices the speed-up first, you end up explaining on the back foot. In the note, say what changes and what stays the same in the same sentence.
Hypothetical example
An example for a rate cut: “Our working time has come down, so we are lowering the rate. We are also shortening the turnaround you have been waiting on.” Give the reason for the cut together with what the client receives.
Hypothetical example
An example for widening the scope: “The price stays the same, and the summary table we used to quote separately is now included.” Put both what is included and what is not in writing. If you do not, the widened scope will be read as having no limit.
Hypothetical example
An example for moving to a fixed fee per deliverable: “From the next one, we will price each report rather than the hours worked. However the work is done inside, what you receive and the standard it has to meet stay the same.”
A&A perspective
A&A thinks that when you set the change of unit next to the unchanged standard, the client can see that what they receive has not changed.
A&A perspective
Even if you choose to keep quiet, you need a note. It is the sentence you will use at the next quote, when you move the basis of the bill from hours to something else. Keep the price without one ready, and the first explanation you give will be when the client asks.
A&A perspective
The steps for telling existing clients about a price change are covered in a separate article, “Existing customer price rise: start date, proration, failed payments.” This article covers the step before that: deciding what form the bill takes.
Summary
A&A perspective
The deciding factor is not the speed-up but whether waiting work can fill the freed time.
A&A perspective
With waiting work, cut the rate; without it, move to a fixed fee per deliverable.
A&A perspective
The time for handoff and checks remains after the speed-up, so include it in the price.
A&A perspective
Prepare the client note at the same time as you decide the billing form.
Bill for work AI has sped up by whether waiting work can fill the freed time, not by the size of the speed-up. All this article borrows from the two cases is the distinction between the two situations after a speed-up. The way of choosing a billing option is A&A's own design, not something drawn from the sources.
FAQ
Isn't it more honest to pass the AI savings on to the client as a price cut?
If you have waiting work, a price cut is a sound choice. Cut without it, and every gain in efficiency shrinks your revenue. A&A thinks honesty shows less in the amount than in updating the basis of the bill and explaining it.
Can I move to a per-deliverable fee under a contract that settles by itemized hours?
Sometimes you cannot. With clients or contracts that require an hourly breakdown, the options left are a rate cut or widening the scope. Even then, put the time for checking and handoff in the breakdown and bill for it.
What exactly should I count as waiting work?
Count the quotes you turned down in the past three months for lack of time or capacity, the inquiries you have left unanswered, and the clients you are keeping waiting now. If the count is zero, the freed time will not be filled by the next job; it will simply sit empty. This way of counting is A&A's own design, not a standard from the sources.
