Happy day Bob,

Wait, isn't this Reddit?  I always get the best advice from Redditors.

A more clear representation of the facts:  You want to manufacture goop.  To sell it, you have to comply with FDA requirements.  Using a credit card, you paid $300 to attend a workshop about the requirements and what an inspection would entail.  You were so impressed that you hired the company that put on the workshop to come and do a pre-inspection report.  You forked out $50k via check and the report highlighted that you have too many bug parts in your goop, and ways to reduce bug parts so that you can pass the inspection. 

Two transactions, two different activities, probably provided directly owner, to one customer.
