Compare previous billed users count and new one from preview
Problem
If the group has an overage and adds a user that will not increase already existing billable members count we should not show the overage.
Currently we rely on API field hasOverage
to show/hide the overage
Proposal
Add one more field willIncreaseOverage
that would compare current billed user count and the one from the preview. If the number will be increased return true
, otherwise false
.
