By default, Wholesale All In One app uses "Draft Order API" logic and so if a wholesale customer places an order with the app, then the order will be generated as a draft order initially and then will be converted as a normal Shopify order after payment.
However, If a wholesale customer leaves the website from checkout page without completing order payment step then you will see a relevant draft order.
- It's not a complete order because customer left the website without complete it.
Please see the diagram below to understand when WholesaleAIO app generates the Draft Orders.
There is another alternative method called 'Coupon Code' discount method that doesn't generate Draft Orders for incomplete orders.
