Real Money Microtransactions

What percentage of the real money spent by players on microtransactions shows up in the finance report? It is not 100%, or if it is then the individual building service tab is not accurate.
For example, I have one blacksmith that got used 484 times in one day at $10 a pop. But the microtransaction line item on my finance report only stated $3,930.00 for the whole day. (there are many more microtransaction buildings collecting cash as well, so it is not just easy math of 4840-3930=910; or 19% loss of microtransaction cash).
