Over the counter sales vs in hospital use

Hello!

For tax and book keeping purposes I need to make sure everyone is on the same page and following the correct protocol.

If a non-client comes in to make a purchase (license, treats, toy, etc.) please use account #0  and choose either canine or feline.  Enter in the charges and conclude and take payment as usual.

If you take a product for in hospital use, please enter it under account #1128 and use canine or feline and enter it at normal price.  Once monthly I go through the hospital account and conclude it and file the paperwork for book keeping and tax purposes.

Any questions please let me know.  Thanks!
