This guide explains what Claude costs a ten person company per year, and why the answer is never a single number. Most owners start with the price list and multiply by ten. That misses two of the three lines that end up on the invoice.
The first line is seats. A seat is a named licence that lets one person use Claude in the browser, the desktop app or on mobile. You pay for seats per user, per month, whether or not people use them heavily.
The second line is API usage. The API (application programming interface) is how software, rather than a person, talks to Claude. It is metered: you pay for the text Claude reads and writes, measured in tokens, plus any paid tools such as web search.
The third line is setup work. This means connecting Claude to your CRM, helpdesk or accounts, writing the instructions it follows, agreeing a usage policy and training staff. It is a one-off cost with a smaller running cost for upkeep.
A company that only buys seats has a predictable bill and a limited result. A company that connects Claude to its own systems pays more in the first year and gets work done inside the tools it already uses. The rest of this post takes each line in turn, then puts them together in three worked budgets.
