Ok I have figured out most everything with this app and I am loving it! This really is what I have been looking for and I want to thank you for such an genius app. Here are a couple things I would like to see in the next version. Being able to select a discount in a money amount or a percentage. This would be a big help. The other thing is being able to do a split sale. I understand how to do the split invoice and I think that is great but sometimes I have customers that want to pay half in cash and the other half on a credit card and being able to split the sale would be a great help.
Thanks a lot for your nice feedback! I really spent a lot of my free time developing TabShop. To the discount value, you can always add a custom invoice position and name it discount and assign a negative value to it.
A split payment is something i have to somehow implement in the future.
