We are aware of many stores who use the order audit trail for a 'history'
of the total transaction. We do this as well, except there are currently some
holes that could be filled with a few simple changes.
1. Provide the option for the seller to attach the drive-thru message to the
order
2. Provide a 'link' to the invoice (not just a date invoiced)
3. Allow sellers to 'attach' any PM's that have been sent
4. Maintain transactions dates for the order rather than simply changing the
date when an event takes place. If someone adds a batch - that is a separate
date from the original order date. In the same way if there is a item removal
done etc., etc.
Sellers could then have a completed audit trail of events surrounding the order
(if they wished).
In reality this would help not only the seller but the buyer as well.
