The bundles feature in QuickBooks is pretty powerful but it's a little bit confusing. There is no way to set a price for a bundle, the price will always be calculated based on the items that you put into the bundle. So if your exam costs $50 and the rabies vax is $22, then the bundle will cost $72. Of course, you're probably trying to offer a discount, so the trick with bundles is that you can add extra bits to them (like a "discount" item, for example) in order to get the price to be what you want.
Here's an example of a "Legal Beagle" package where we created a separate "Legal Beagle Discount" item to adjust the price. Unfortunately QuickBooks does not display pricing information here, so you have to manually calculate the amount of the discount in order to make the math work out:
But once you use this bundle as a "Treatment" in VetBadger, the price is correctly set on the invoice. Notice the "Display bundle components when printing or sending transactions" checkbox, the default setting (where the checkbox is NOT selected) will hide the components of the bundle from the invoice and just show the total price.
This might seem a bit strange, but it has the advantage of giving you access to reporting on the discount item, which lets you see how effective the bundle is from a business perspective.
On the other hand, there is a feature directly in VetBadger called "estimate templates" that lets you do similar things in a way that could make more sense for you.
