QuickBooks Enterprise needs an item number for creating a purchase order and invoice.
If you have already set up an item in QuickBooks Enterprise, ProcureDesk will automatically import that for you.
For generic items like office supplies, you want to create a new item in QuickBooks Enterprise that can be used for syncing the purchase order with QuickBooks Enterprise.
Here is how to do that.
1. Log in to QuickBooks Enterprise.
2. Go to List->Item list
3. From the item menu, click on New
4. Create a new item as following and then click on "Ok"
