When work is not done, somebody has to notice. The ladder decides who, and after how many minutes. It is one set of rules for the whole business, it is checked once a minute, and each step leaves a note with a message ready to share.
Team / Reminder rules, with the timings a new account starts with. Only the owner can change them.
Each step of the ladder leaves a note here with a ready message. The manager shares it or clears it.
No setup fee. No charge per branch.
