How to deal with a customer?

Question

Work organization

The bottom line is that the customer controls the code completely and rolls out every day to make them do it differently, this practically stopped the development, because all I do is edit the previous blocks. There was no mention of this when the contract was signed. For you to understand, claims are made not by errors, but by algorithms and their implementation. What to do in such a situation?

Answer 1

talk to the customer

Answer 2

If you make changes, then you see the shortcomings of your solution. Apparently, you are faced with a case when the customer is more professional than the performers, which is extremely rare. Enjoy free training if the customer is satisfied with the delay, but it is necessary to discuss the speed of progress, taking into account the refactoring, or include it in the contract.

Answer 3

Break down the goal into tasks and agree on the scope of work and cost for each. And do not rush to extremes in terms of the scope of the task. The optimal time to complete the task is 1-3 days.

Answer 4

When the contract was concluded, there was not a word about it.

Read the terms of the contract and act within the framework of the contract, observing all the conditions!

Answer 5

If the contract allows you to abandon the project without loss, then I would refuse, since with such a customer there is a chance not to earn money at all. Perhaps his perfectionism is due to the desire to get a job for free and when you complete it, he will have something to show you (missed deadlines, poor code quality, etc.).
Otherwise, formally fulfill everything under the contract, give the order.
