Hi AngelaL10
Welcome to the Community Forum. Generally, we would see a change in the Cost of Sales when a purchase is entered, then later the price on the bill is changed, as the software will then do an automatic cost of sale adjustment to correct the change in price.
It sounds like this is happening in your case, but just to double-check can you provide more details on what exactly is entered the first time, and what is being edited?
If you could respond with screenshots of examples that will give me a bit of clarity on what the software is doing in the back end as well.
