Whether your firm should build or buy was never about the app. It's about whether you can supply the harness and the janitor yourselves. Part 3 of Buy vs. build closes the series with the build-readiness test, the packaging premium, and one question per layer to ask before any renewal.
Basis says it takes responsibility for the first pass of your clients' tax returns. OpenAI, four days earlier, refused to claim authorship of work its own model did and took responsibility only for its correctness. Both sentences are about who is answerable, and only one of them means it.
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.
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.
Karbon asked clients what should happen to your fee when AI makes the work faster, and 37% said it should come down, which is close to what the IRS told tax practitioners in June. Deliver something they have never had instead and 54% will pay more. Three of the four walls of the pricing vise moved in a single week.
Xero has had a request open since 2017 to let you export bank rules, with 540 votes and still nothing shipped. QuickBooks Online has done it for years. As your firm starts encoding real judgment into AI agents and skills inside vendor platforms, that gap stops being a nuisance and becomes the question that decides whether your build compounds for your firm or evaporates.
