I don't want to derail the thread, but I'll just say be prepared to add a few paid extensions when planning your budget. It's not a dealbreaker, and there's some excellent extensions, but you will on occasion wonder why it isn't core functionality.

@Mark118 that workaround makes a custom sale possible, but you can't track inventory, departments, vendors, etc. What people are asking for is to be able to add a product ahead of time where the price can be entered at checkout.

Not particularly ideal when you have a lineup of customers at the cash register. Just allow price overrides or add another field or two to the custom sale function.

They're *almost* there with the price override option, it just needs to not show as a discount on the receipt, and perhaps let you increase as well as decrease the price.
