Hi i am getting an error when trying to pay a sales order

Hi christine999, 

Thanks for your post. Generally this error can occur if the inventory items in the invoice do not have "I inventory this item" ticked, I would recommend checking this. If all the items have correct allocation accounts specified, check the linked accounts for sales under Setup>>Linked Accounts>>Sales, complete any missing accounts. 

Do let me know how you go.
