B2B business.
The other party like the concept but don’t like the design of the product.
(By Other party I mean Cafe owners mostly).
Everyone (cafe owner)has own unique preference and demand!!
How to solve this issue?
Owners like the concept but complain about the design.
If I modify design according to them the production cost will increase. Then I will not be able to provide them the product at suitable price. Then again they will not buy the product and start to complain about the selling cost
How to sort out this issue?
If this is software (you don’t specify) make the product skinnable so that you can customise the design for each client in a config file. This is often called whitelabelling. Up-front production costs might be higher but you reap the rewards later. I did this for a large insurance firm who sold the system to multiple clients. We could build reskins of an e-commerce site in under a week.
