01In plain English
A seat is one user. With per-seat pricing the plan price is multiplied by the number of people who need access. Some tools charge only for people who edit and let viewers in free, which changes the total a lot.
02How it works
The vendor quotes a price for one person for one month, and the invoice multiplies it by the number of seats you have. Add a colleague and the bill goes up by one seat, remove someone and it drops. A seat is tied to a named login, so sharing one account between two people usually breaks the terms. Many vendors sort people into roles, with full seats for editors and cheaper or free seats for people who only view. Some set a minimum, such as three seats, and some give a discount on larger groups. For example, a tool at a modest price per seat is a small cost for one freelancer but a large line item for a department of forty.
03Why it matters when you are choosing
A tool that looks cheap for one person can be the expensive choice for a team of ten. Comparing per-seat tools with flat-rate ones only works once you multiply by your real headcount.
04What to check
Check whether viewers or guests need a paid seat, whether there is a minimum number of seats, and whether you can move a seat to someone else.

06Common questions
What is a seat in software pricing?
A seat is one licensed user, usually tied to a named login. If five people need to sign in, you need five seats. Some vendors count only people who edit or create, and let viewers, guests or clients in at no cost, so read how the vendor defines a seat.
Is per-seat pricing cheaper than flat-rate pricing?
It depends on team size. Per-seat plans are cheap for one or two people and get expensive as the team grows. Flat-rate plans can cost more at the start but often win once many people use the tool, so multiply the seat price by your real headcount before comparing.
Can two people share one seat to save money?
Usually not. Seats are tied to named users, and sharing a login typically breaks the terms of service. It can also lock you out when the system detects logins from different places. Ask the vendor about a cheaper viewer or guest tier instead.
