In business travel, the acronym POD stands for payment on departure. When a guest pays for their hotel stay after it is complete.
One way travel management companies can help companies is providing them with a credit account. In this way, the TMC pays the POD fee for the traveller. They later bills their client to reclaim the money.
The benefit of this method of payment is that it saves the traveller from having to sort payment and reclaim it from their organisation via expenses.
