I have started a project with a client where the deal was to upfront an amount of money, then he will do escrow for all of the remaining money, with it being released after completion of the project. I have started working on the project already.
Initially, I sent the design to him he said the design is fine for him. I have sent many builds for getting feedback, generally every 3 to 4 days. But, he didn't provided any response, and I continued working, by thinking no feedback means client is good with what is going on.
I just provided the last build (Complete) a week ago, but now client does not come online. Before, his site was down for a week, so I contacted him and he had responded and solved the issue. However, I am now not able to communicate with him. What could be done now?
Also, if the client comes back and if he suggest a big change, what should I do? As you all know, if a change is given after completion of the app, it will require lot effort to fix, rather than if it would be specified at the development time itself.
