TL;DR
- Firms keep buying AI tools that end up barely used. The recurring pattern in accounting and legal communities: tools that add a verification step instead of removing one, or clear procurement and never enter the daily workflow.
- At the same time, nearly two-thirds of law firm professionals say their pricing hasn’t changed despite AI-driven efficiency, even as clients expect cost certainty and transparency tied to that efficiency.
- Two decisions matter before you sign a vendor contract or touch your rate card: does the tool remove a step or add one, and does your fee structure reflect the value AI creates or just old hourly assumptions.
- This post is a short checklist for both decisions.
Two mistakes show up constantly in professional services right now, and they’re related. Firms buy AI tools that never really enter daily use, and firms keep billing the old way even after AI changes how fast the work gets done. Fixing either one starts before the purchase order or the rate card, not after.
What should you ask before buying an AI tool?
The most common failure pattern in accounting and legal AI adoption isn’t a bad tool. It’s a tool that clears procurement and then almost no one opens more than an hour a month. Before signing anything, run the tool through five questions:
- Does it remove a step, or add one? If your team has to verify the output as carefully as if they’d have done the work manually, it won’t survive contact with a real deadline.
- Is it grounded in sources your team already trusts, or does it ask for blind trust in a black box? Tools with one-click citation checking get used. Tools that don’t, get abandoned.
- Does the vendor offer a no-training agreement, zero data retention, and tenant isolation for anything touching client or donor data? This isn’t optional for confidentiality-bound work.
- Would it survive two weeks in your real workflow, not a demo? The clearest sign of a bad purchase is a tool nobody logs into a month later.
- Is the price justified by real integrations and security, or is it a general-purpose model with a premium label attached? If a cheaper baseline performs comparably on your actual tasks, the premium needs to earn its place.
What should you ask before changing your fee structure?
Financial pressure to adopt AI is rising fast, but pricing hasn’t kept pace. Almost four in ten law firm professionals feel pressure to move faster on AI, yet nearly two-thirds say their firm’s pricing structure is unchanged. Meanwhile, clients are explicit about what they want instead: pricing models that reflect AI-driven efficiency through greater cost certainty and transparency.
Three questions worth answering before you touch your rate card:
- Are you billing for time, or for the outcome? A fee structure tied strictly to hours worked doesn’t reward the firm for using AI well, and it invites clients to ask why they’re paying the same rate for less time.
- Are AI tool costs and pass-through expenses disclosed and consented to, the way several state ethics opinions now require? This is already an active compliance question in jurisdictions like Virginia, not a future one — we covered the specifics in our Maryland, DC, and Virginia AI guidance post.
- Can you explain the fee to a client in one sentence that ties it to value delivered, not hours logged? If not, the pricing conversation is going to happen with or without you.
What’s the bottom line?
Before you buy: does it remove work or add a step, is it grounded and secure, and would it survive two weeks in real use. Before you bill differently: are you charging for outcomes or hours, is every AI-related cost disclosed, and can you defend the number in one sentence.
Bottom line: the firms losing money on AI aren’t the ones moving slowly. They’re the ones that bought first and thought about workflow and pricing after.
