1. what you buy to keep on hand and sell is defined as inventory
2. the process
2a. you buy a car, use a cash type bank account account named for the car (all taxes, shipping, etc)
2b. use that same account for any purchases or expenses that are needed to get the car ready to sell
2c. when the car is ready to sell, create the inventory item for the car
2d. buy the inventory item from a dummy vendor and use the cash type bank account named for the car to pay for it
2e. rename the cash type bank account to something that means it is zero balance and can be used for the next purchase
2f. sell the inventory item
Inventory items have three accounts
expense = COGS
income = your sales income account
asset = inventory asset
