As a dental clinic we sell our own products, when selling the products our staff get commissions and it'd be easier to calculate those commissions if there was a way to save the product prices in Weave.
Example: Toothbrush is $10.00. With sales tax it's $10.25.
On Weave there'd be an option when creating an invoice to select multiple products at once and selecting which ones have sales tax. (Our services don't have tax added so we wouldn't want the tax added to those specific prices).

This would help us save time while patients are purchasing items and prevent human error when doing the math and over or under charging a patient.
