Flat pricing vs per-seat pricing: what is the difference?

Flat pricing vs per-seat pricing, explained#

Per-seat, also called per-user, is the default for most business software: a price per person per month, with a minimum or tiers. It is easy to understand and scales with the customer. Its downside shows up in small teams. Every new hire, contractor or occasional collaborator is a new line on the bill, so teams start sharing logins or leaving people out, which defeats the point of a shared tool.

Flat pricing charges for the plan instead of the person. A plan includes a number of seats, or unlimited seats, and sometimes an allowance of usage such as projects, storage or AI runs. The bill is predictable, and inviting someone does not need a budget conversation. The trade-off is that a very small team may pay for capacity it does not use, and a team that outgrows the plan takes a bigger step up.

Many products mix the two: a flat platform fee plus per-seat charges above a threshold, or per-seat pricing with free read-only guests. AI features add a third axis, because AI costs the vendor money per use, so plans often include a usage allowance alongside seats.

To compare fairly, price the whole team you will have in a year, not today's headcount, and include add-ons such as AI. A per-seat price that looks cheap per person can cost more than a flat plan once the team doubles.

For example, a six-person team compares a tool at $12 per user a month ($72) with a flat $49 plan covering ten seats. Today the flat plan is cheaper. If the team grows to ten, per-seat costs $120 while the flat plan still costs $49.
