Emma, Seeing as some dev tokens recently got suspended for low usage, this probably is not practical unless a client is extremely large. An option would be to pass the API cost on to the customer, but obviously this might be a barrier of entry for some smaller clients as their budget probably is small to begin with.
Something that helps to keep costs down is using the new reporting service and sliding date ranges. This allows you to store report definitions for each client for a one time cost of 400 API units per report type and retrieve the reports at no cost from then on. This is only a solution if you regularly request the same information for a specific time period. Something that helps in tracking unit usage per client in an MCC is the InfoService which can be used to get API unit cost per client by service or even by method. Obviously it costs an extra unit each time you use this service, but if you are just using UNIT_COUNT_FOR_CLIENTS and not filtering by service or method it is very cost effective to track usage per client for each month. Hope this is helpful!
