Being a wholesaler, our profit margins are low. This is why delivery costs are really important for us. When we do deliveries ourselves, we need to pay for vehicle lease, insurance, and delivery driver. It adds up to a large number quickly.
Additionally, we pay our drivers by the hour when we do the deliveries ourselves. This is a challenge. I do not know the exact amount until the deliveries are over and I cannot foresee it.
On top of all, delivery visibility is critical. I estimate the delivery to be completed by 10 AM but it sometimes takes 3 more hours. If I cannot tell my customer when their packages will be delivered, they will lose from their working hours.
