For clarification (particularly on balance sheets) "in-kind" is not a blanket term to use whenever there is something exchanged in w/o cash. 

There is a critical distinction between donations coming in to your org, and donations going out that your org makes. 

"In-kind expenses" represent donations coming in to your shop (i.e., they are assets you've received that you would have otherwise had to pay for). 

"In-kind donations/contributions" represent donations your shop is making out into the world.

Also, importantly, you can't consider trades to be donations because you have the same on-paper asset value at the end of the transaction.
