How do you address a customer who you knew you had issue with while selling a product to?

As every customer is important and in Marketing process you put all leads in funnel and filter them and then keep rest in pipeline ,that means you cant ignore any customer because it can become a future prospect.

 

if its tough customer I think approach should be bit careful as you have mentioned customer doesnt convince easily and others had difficulty selling.

First step should be doing analysis on last sales call made if data available what were the reasons customer has not bought product , if reason was there was no NEED and salesperson kept pushing, If he/she forgot to add value with product or service offered.

Was customer concerned about after sales support, If customer has different mind set about the company which offered product during last sales call, so such factors surely will give a good idea why customer objected.

Take care of such issues and put your best step forward I am sure this SALE will be successfully trhough if not make such a rapport that they call you when there is real need for offered product /service.

 

First listen to your customer previous grievances and try to address with proper justification and present your apology for not handled properly previously. And then start selling your new product with complete details & it's features .

For me I have a policy forgive and forget every customers is new to you business every day regardless of whether its a regular guest or not so your appearance will invite or chase them away for you to have perfect and excellent service don't focus on the past treat the customer as your investment you'll last long
