Adding Retail with Inventory?

Mr. Henry Wang of Global Incorporation Limited 环球致优 with offices in Hong Kong, Beijing, Shanghai and Shenzhen has proposed to add the retail with inventory function in CPAnywhere.  The problem with this proposal is that the initial target users are for professional firms.  All billing for inventory items would usually be classified in either Miscellaneous Charges or Reimbursable Items.  Almost all accounting systems in the market are retail based.  CPAnywhere is unique because the system is geared mainly to professional firms.  However, that doesn’t stop us from putting this Retail with Inventory module in CPAnywhere.  I have been thinking about this proposal everyday in order to find the solution to the problem.  If you have any suggestion to this dilemma please let us know.
