Monday.com forces users to purchase seats in fixed increments (5, 7, 10, 12) rather than allowing one-by-one increases, and has a security issue with 'Authorised Domain' being enabled by default.

FlexiSeat Pro

FlexiSeat Pro is a project management platform that offers truly flexible seat licensing and enhanced security controls. Unlike Monday.com, it allows administrators to add or remove seats one at a time with transparent pricing, and provides granular security settings with sensible defaults that don't compromise organizational safety.
