Delivery to your client’s office is an opportunity to market your services to your client’s guest. Take advantage of it. Always bring some extra menus and tastefully intersperse among your offerings. Leave business cards on the table or with the receptionist.
Restaurants offering pizza delivery have perfected the art form by leaving menus and coupons for your next order. The next step however should be to call the customer back after an appropriate time and ask how the meal met their expectations.
Never forget every delivery however small is a sales opportunity.
