I can share some information about how purchase order works, info-hikokistore.
POs are used to tell vendors what items you want to order and track the upcoming expenses. Normally, you'll only need to enter specific items you want to buy and the quantity in the Item details section.
Categories are rarely used in purchase orders, as it defeats the purpose of receiving inventory items by using a purchase order. If you do not use products and services, then you can use this section to select the accounts affected by your purchases. You may consult your accountant in selecting the correct accounts.
Additionally, purchase orders are non-posting transactions. They won't reflect in your Chart of Accounts. report totals, and vendor balance. You're always free to create as many as desired, void, delete, or alter regardless of the date on the form. None of these activities will affect the financial reports of the company.
