Business Teams SSO

I have a small IT team I want to use 1Password. (as I have been a personal user for as long as I can remember).   But I the Teams subscription is missing on key piece. so I am now in limbo and looking at alternatives.

SSO is a major feature for us but. The team is only four members, but the teams account is within budget but missing SSO. The business package does have SSO but needs a minimum of 20 users, and with the cost difference, it is way out of budget.

The business doesnt understand the benefits of Password management, yet so I would be fighting a loosing battle to try and roll out to other departments, until I can prove my case within my own team.

As 1Password is a security product it does feel like an odd feature to not have as a default on all the business tiers.   But my sales contact is only suggesting I try and get buy in from 16 more users and get the budget, if I want that feature. (not the best sales experience if I am honest. Which is such a shame as I love the product.
