Alot of sales jobs are heavily reliant on kpi's this key performance indicator lets your employer know that you are pulling your weight for the business. If a salesperson managers to get the customer to come back and buy a product but the customers only focus is on who is available rather than waiting for the initial salesperson who helped them then the business will benefit but it won't reflect who was truly responsible. Not alot of customers know this but its the ones who do come back and wait for the initial salesperson that help keep the appreciative salesperson employed. So thank you to those who take the time to wait for those who have helped you for it is appreciated.
