To add a new supplier, first, go into the Suppliers window, then press on the blue Create Supplier button.
A new pop-up window will open. Here you need to fill out suppliers' details that we will use later when creating purchase orders.
We can now see that a new supplier has been added at the very top of the list. To see the full details simply click on the blue supplier name.
Inside you will be able to see all of the information you filled in when creating the supplier and all of the future purchase orders created for this supplier will appear here as well.
To edit supplier details, simply press the grey Edit button to the right of the supplier name.
After pressing Edit the same window we saw at the start will pop-up. Make any changes you wish and press Save, otherwise press the grey X at the top of the window.
