The effort to
- create virtual cards for each trade show using a spend program
- setup the card rules to link the cards to the accounting field
- train employees to relink their physical card prior to each event to a new virtual card
- then ensure that if they forgot to do that, verify that they relinked transactions to the correct card
is all more effort, than what we currently do, which is pick the trade show on the accounting dimension for each transaction.
The most intuitive way would be have some defaults on the trip, since it is easy to configure, doesn’t require additional cards and employees can do it themselves, without any admin help.
