The return showed up. It just wasn't in hours.

The return showed up. It just wasn't in hours.

In the late 1990s I helped build a global audit platform for a Big Six firm. The capability let us do some old things faster, and start doing things we should always have been doing and never could. Quality went up. The clock never moved. Leadership was watching the clock, saw nothing, and cut the budget. If you are measuring AI in hours saved, you are about to read the same zero.

Buy vs. build, part 2: The pricing wrapper nobody reads

Buy vs. build, part 2: The pricing wrapper nobody reads

Per-client and per-user app fees levy a decision tax accountants have paid since QuickBooks Desktop gave way to subscriptions. Part 2 of Buy vs. build reads the pricing wrapper the way an accountant should, as a risk contract: who carries the token volatility, who holds the repricing option, and what to watch as usage-based pricing arrives.

Weekly AI Roundup for Accountants: A better answer is not a better firm

Weekly AI Roundup for Accountants: A better answer is not a better firm

Anthropic shipped two things this week that answer the same question in opposite ways: a feature that turns one screen recording into an editable procedure file, and a model that checks its own work brilliantly and remembers none of it. Meanwhile OpenAI launched a program teaching small-business owners to do their own accounting, and a top-15 firm committed its whole client accounting practice to a firm-trained AI model. The question running under all of it is which of these leaves anything behind.

Cleaning up after AI should cost more than the bookkeeping did

Cleaning up after AI should cost more than the bookkeeping did

A returning client chose our cheaper self-service tier, left the integrations broken, and handed us a year-end file so damaged we spent more hours than the full-service fee would have covered — then balked at the bill, took the discount, and left anyway. Every firm runs some version of that inversion: the cleanup, the harder job, is the one we discount. As "my AI does the books" spreads, here's the pricing mechanism that stops it.

The agents could run the meeting. Should they?

The agents could run the meeting. Should they?

Last week the joke was that your client's agent could talk to your firm's agent and clear the busywork overnight. That's right — for the friction. But today your advisory relationship is largely a byproduct of all that transactional contact, and automating it blindly severs the thing advisory grows from. Here's how to tell the contact you should automate from the contact that is the whole business.

Weekly AI Roundup for Accountants: The AI tax-prep wars just began

Weekly AI Roundup for Accountants: The AI tax-prep wars just began

Canopy, Drake, and Firm360 shipped AI tax-prep automation on the same day, the largest open-weight model ever released is days from being free to download, and OpenAI's CFO published an AI ROI scorecard with no line for verification. The pattern across the week: everything below the review layer is being absorbed or given away — and the review layer is what's left to charge for.

The $49 close assumes a system that hasn't yet been built

The $49 close assumes a system that hasn't yet been built

In one 48-hour stretch this month, AI's price sheet fell again — Meta, GPT-5.6, and Grok all repricing the intelligence behind the $49 close. But the vendors selling that close won't quote a flat price for it, because the thing that varies was never the intelligence — it's the system underneath. Run-time is commoditized; designing that system and standing behind it isn't, and that's where the fee now lives.

Your client's agent can reach their bank. It can't reach you.

Your client's agent can reach their bank. It can't reach you.

Every system in your client's business is becoming something their AI can reach and act on — their bank, their payroll, their card processor. Every one except the firm that's supposed to be the most intelligent of the lot. Here's what it looks like when an accounting firm designs for the agent, not just the person — and why you start with the contact nobody enjoyed anyway.
