The 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
Fill out all the product details and click Save
To display it on the POS, go to Menu > Settings > Account > Refresh Products
That's it! If you get stuck at any stage, we're here to help!
