This is simple, in fact it is a no brainer really
If you believe in your product, and you think that your client NOT buying from you will harm their business, then it is your DUTY to fight for what is best for your client! If you fail to convince them to buy then you have let THEM down, not yourself.
Many weak salespeople leave a client in the lurch by not closing the deal. They awake a need in the client for the product or service they build the desire for the product, yet fail to take the necessary action to do what is right for the client. The client YOUR CLIENT, will then go to another company where he will get an inferior product, the same product but at a higher price, or an inferior product!
AND IT IS ALL YOUR FAULT. ------ Think about that for a second because if you believe in your product then the statement is true. If you do NOT believe in it, then get a different product to sell, because product belief is everything.
Once you believe in your product, and believe that your client will be worse off for not buying from YOU, you WILL close more deals, it is as simple as that.
When you believe in a product you become passionate.
If I was paying you to sell $10 notes for $9 how many would you sell?
WHY would you sell that many?
so if you sold a product to a client that would earn him $10 for every $9 he spent you SHOULD sell the same amount right?
Get your mindset right, and do what is best for your customer. Prospect better, present better, sell more, earn more, get more referrals. and you will have become a professional salesperson.
