If a Client is put on a different plan, when does that take effect?  

New plan changes occur on the first of the following month. If you change a Client from monthly plan A to monthly plan B on the 1st, 15th, or 31st of October, they will finish out October on plan A and be automatically put on plan B on the 1st of November.
