Navigate to the “settings” page from the left-side menu.

Select “suppliers” on the settings page.

Click on the “add new supplier” in the top right corner.

Fill in all the required details in their respective boxes.

Here, you see a box “estimated arrival setting”. What it will do is let’s say you select 5 days in there, so when you have the suggested amounts to re-order, in the reorder setting, it will tell you to reorder 5 days before. 

Click on “create” to add the new supplier.
