The proper reporting of lost sales is paramount for your parts department when trying to properly monitor the demands made on it by customers. Recording lost sales is critical to accurate ordering and stocking levels. However, it is easy to find disagreement among parts employees over lost sales. Tracking lost sales is far from science and can take a lot of experience to understand.  For some parts managers, a lost sale is registered any time a customer, or even if a service department asks about a part and the dealership can not say “Yes, we have that”. Others want many qualifying factors met, lots of questions, and lots of technique, either way, the tools are in your hands.


Here are some examples of lost sales and occurrences where there was not a lost sale:


  • A customer comes into the parts department and inquires about the price of a new helmet. The parts person gives him the price and the customer asks to purchase the part. The parts person informs the customer the part is not in stock and will need to be ordered. The customer leaves the dealership and does not order the part LOST SALE 
  • A technician has put together a list of parts for an insurance crash estimate. The parts department doesn’t have the part in stock and the customer unit gets totaled out requiring only billing for the inspection hours. The parts were then not ordered. NOT A LOST SALE
  • A customer needs a part normally kept in stock. When the customer tries to purchase the parts, they are informed it is on backorder for a week. The customer says, “That’s ok. I’ll see if I can get by for a week.” LOST SALE
  • The customer calls on the phone. Asks the price of a part. Doesn’t make it clear as to any intention. NOT A LOST SALE
  • A customer comes into the store to buy an XXS signature edition helmet. Typically you do not stock this size and when you inform the customer you would need to special order that helmet, the customer lets you know they want to check around town first. LOST SALE 
  • A customer comes into the parts department to buy a tire you have in stock. When the customer brings the tire to the counter they asks if you can match the online price of a competitor. You are not allowed to price match, so the customer leaves without purchasing the tire. LOST SALE 


Each dealership must set Lost Sale guidelines for their parts department. If this is a new concept for your dealership and team, then this is a perfect opportunity to do some research, additional training, and develop the guidelines for recording lost sales. If demand is not tracked properly, it is very difficult to have the right products in your dealership, ready to take care of that next customer.
