Edit Mode let's you create a product from within the app. However, we recommend that you use a computer for this as it is easier.
To add/edit a product on the fly, open Edit Mode on the Countr app
Select 'Product Create' to create a new product or click 'Edit' on a product that you want to modify
Once you are done, hit 'Save'
Go to Settings > Account > Refresh products to display the product on the POS
