Where it usually breaks
And how to keep it from happening.
- The order connection was never set up, and Pending receipts build up without anyone watching them.
- Someone types an order number into external reference by hand and expects the receipt to complete; reconciliation does not accept it without provider confirmation.
- A handoff is started on a quote that was accepted under an earlier revision, and the revision check refuses it.
- The order system creates an order but the confirmation never comes back, leaving the receipt Pending.
