How do you manage wholesale orders and preorders while tracking sales rep commissions?

Hi!

What solution do you guys implement to sell wholesale

Take preorders while allowing your customers to skip checkout and pay only once the preorder has been shipped

And how do you take into account wholesale orders from sales rep and other customers. Track their commission if any. Thank you!

Shopify does allow invoicing with terms. Also, a couple of apps I have dug pretty deeply into and may meet your needs are Wholesale All In One and Wholesale Club. But, those are also focused on self serve applications.
