    Per-seat pricing quietly taxes growth

    Direct answer

    Per-seat pricing looks cheap on the first invoice. The cost curve is the problem: every hire raises the bill on every tool that person needs, and nobody re-approves the decision when that happens. Once headcount on a single tool passes roughly thirty, compare the two-year subscription against a one-time build. Sometimes the subscription still wins. That is worth knowing rather than assuming.

    Per-seat pricing creates a predictable cost-of-growth tax that compounds with every new hire and reprices the tool's value retroactively.

    What arithmetic is worth doing?

    Per-seat pricing is easy to approve because the first invoice is small. The cost curve is the problem: every hire raises the bill on every tool that person needs, and nobody re-approves the decision when that happens.

    Once headcount on a single tool passes roughly 30, comparing the annual subscription against a one-time build stops being a philosophical argument and becomes an arithmetic one. Multiply the seat price by the headcount you expect in 24 months, not the headcount you have today. The same discipline shows up when we price AI consulting for a small business and when we choose build versus buy inside AI for Small Business work.

    What should the two-year arithmetic include?

    • Count seats you will need in two years, not this quarter
    • Add the cost of the integrations you maintain around the tool
    • Compare that total against a build plus its running cost

    Sometimes the subscription still wins. That is a fine answer, and it is worth knowing that it is the answer rather than assuming it.

    Frequently asked questions

    When does per-seat pricing stop being the cheaper option?

    Once headcount on a single tool is heading past roughly thirty, run the two-year seat total — plus the integrations around the tool — against a one-time build and its running cost.

    Should I count today's seats or future seats?

    Future seats. The first invoice is small because it prices the team you have now. Hiring is what quietly raises the bill.

    Does this mean every tool should be rebuilt in-house?

    No. Sometimes the subscription still wins. The point is to know that, not to assume it.
