How it works
Follow one order from the PO to the payment
The easiest way to understand duebird is to watch one order go through it. Here is one from Harbourline Foods.
Harbourline emails a purchase order
It lands in your AR mailbox as usual, which forwards to duebird. duebird sees a PDF attachment from a known customer and puts it in front of your team to let in. Newsletters and replies are left as mail.
Two items match. One needs you.
duebird matches BRK-22 and NTR-6 to your products from Harbourline's earlier orders. RAG-25 is new. It asks whether it's your existing shop towel product or something to add. Once you answer, the order is created by itself.
Catalog · 1 questionNeeds youHarbourline's PO lists RAG-25 Shop towels. It looks like your product Shop towels, 200 ct (TWL-200).
The warehouse sends a delivery note
38 of 40 cases of brake cleaner went out, plus all the gloves and towels. The shipped lines become billable now. The 2 remaining cases stay on the order until they ship.
An invoice with its backup attached
Each line shows the PO line and delivery note behind it. Sales tax is worked out for British Columbia. Harbourline requires the PO and proof of delivery, so both are attached. The invoice goes to the approver for this customer.
