Ann: New SME Pricing, page-4

I still don't understand what happens if you want to use more than your allocation. Say you are on the standard plan with 50 included lessons monthly. Now say m1 40,m2 40, m3 35, m4 52, m5 46, m6 37. Now here is an example of what may occur. What happens in month 4 if they want more than 50 lessons but it's a one off. Are they forced to go up a tier, or can they purchase the extra lessons as a one off. The customer will not likely want to increase their plan as most of their usage is within their limit. To purchase the next plan up would be a waste if one month of a year they were to go over but the majority of months are within their plan.

Does that make sense
