Creating an invoice
Entering items in the Invoice Items screen creates an invoice. With the aid of this screen, one item or several items may be entered on an individual invoice. Once all the items have been accepted, the invoice is displayed. As long as the invoice has not been posted, additional items may be added to it, and existing items may be modified or deleted.
Choose the Accounts Payable icon > Invoice tab
Enter the file number or name in the "Find Vendor(s)..." dialog box > Click OK
A blank invoice item screen will appear > Navigate through the fields and fill in the invoice
Make sure that the GL Account corresponds to the Accounts Payable Invoice item.
To create another item for this invoice, click New and input another item, otherwise click Post to finish creating the invoice.
