Under most circumstances the invoice number field will be disabled when creating an invoice. Invoice numbers are usually assigned by the entrée system after all items have been added to the invoice and the OK button is clicked.

 

Manually Assigning Invoice Numbers

Although not recommended, entrée does provide a means for distributors to enter their own invoice numbers by enabling System Option # 16 first.

 

This could be useful, if you deal with manually written out invoices that get entered into the entrée system at a later time. This would ensure that entrée matches your manual system.

 

You will be allowed to optionally enter a unique invoice number in this field.

Should you elect not enter an invoice number, entrée will automatically assign the next available invoice number.

 

  If you enter a number that is already in use by entrée you will receive the Duplicate Invoice Number error message. Click the OK button to return to the create invoice window and enter a new invoice number.
