Inquiry on Customer Orders number, Invoice Number & GDNs number

Customer order numbers are likely to be the number that customers use on their orders.

It is possible, however, to number orders as they come in but those numbers are unlikely to be the same as GDNs and invoice numbers as there will probably be some sort of delay between receiving orders and despatching goods: despatches might not be made in the same sequence as orders are received.

It would be more normal for GDNs and invoices to have the same numbers – indeed both are often created together. The GDN and invoice would normally show the customer’s order number so that the customers could agree these to their copies of their orders.
