If you run a SaaS, you probably want to show your users when they are almost running out of widgets. Or that they can get some cool feature on a more expensive plan. Or, in other words, how can you be nice and commercial in dealing with plan limits. Last week we already looked at how we manage plans & features for Checkly. That write up was very back end focused, so this week I wanted to dive deeper into how we actually show this to our users in a friendly way.

How do you deal with what a user can do on their account in a SaaS app? Can Jane on the "Starter" plan create another widget when she is near the limit of her plan? What if she's a trial user?

This is a run down on the basic multi-tenant SaaS data model underlying Checkly. Users, accounts, plans, that type of stuff. When building this, I found it surprisingly hard to find any solid info in the gazillions of developer and startup blogs; most where just to vague on the implementation details.
