After a few days of heavy testing a Flow solution I got the following warning:

While we are running on Flow Free we get 750 flow runs and during testing we have exceeded the limit.

There are now a few options as once in production we are unlikely to hit the same number of runs.

We could pick one of the above plans to increase the number of runs needed.

Alternatively we could now create a new account and move our flows to that new account by using the export import options available in Flow.

Looking at the licenses in the admin center, I might be able to switch flows a few times.

Then the 3rd option is to enable the 1 month trial for plan 1 or plan 2.

So it looks like there are a few options available to avoid the extra cost while Flow isn’t used too much yet.
