Records & Inventory Reminders

• Randomly check your subscriber contracts to ensure that everything is executed by your subscriber and that all paperwork is in order.
• Randomly check your work orders to analyze and evaluate if they are filled out properly and that your technicians are following your procedures.
• Meet with your insurance agent at least once per year to determine if you have sufficient coverages for each aspect of your business.
• Consistently provide training to each of your employees and document all training provided in their employee files.
• Maintain stringent inventory controls to minimize loss.
• Track bad out-of-the-box equipment, and returns, so that you are not paying twice for this equipment, and so you do not get back repaired equipment when you are entitled to new equipment.
