When you first log in to TM3 the second thing you should do is to set up your stock. This page should reflect the price list for your clinic. There are 4 different types of stock you can set up:
1. Consultancy - You can find out how to create a consultancy item here.
2. Physical stock item - You can find out how to create a physical stock item here.
3. Cancellation/DNA - You can find out how to create a cancellation/DNA charge here.
4. Class/Course - You can find out how to create a class/course item here.
To set up your stock items go to Settings > Setup > Stock. There are three charges already created in TM3 which you can overwrite. You can see these three stock items in the image below. To edit one simply click on 'Edit'.
This will then open the edit charge screen where you can overwrite the details with your own and then click 'Update' when finished.
