Be sure to check every item to be used in conjunction with the sales presentation. If you are using audiovisual equipment, be certain that it is in good working condition. Always carry an extension cord and a spare bulb. If you are making a laptop presentation, be sure you can go online in front of the customer. If you plan to demonstrate a website, save it on a thumb drive instead of going online. Be prepared for technological snags and have the customary multiple backups. Always carry extra batteries for your laptop.19
