I have no accounting experience, I only taught myself enough QB to do the books for a rescue I volunteer for.
I would like to start applying vet bills to the the individuals that adopt our dogs in order to keep better accounting of profit/loss (if that makes sense).
Can each dog be made a job, if so, how to I apply that job to a customer when they adopt? Would it be better to go back into each vet invoice and add the adopter as the customer and make the vet invoice billable. I tried this option as a test, but none of the cost showed up in their account.
Here is the misunderstanding: "but none of the cost showed up in their account."
You Job Track the entry for the Vet bill and that line item. But mark it Not Billable, because you are not Charging the customer who adopted the dog. Track it for Dog under Customer.
Now run Profit reporting, such as Job Profitability Details and P&L by Job.Now you see income and expense. The expense is assigned as directly for that job, but not seen in Customer Center. It relates to the Vet Name = the Payee.
