How much involvement does the client have in the whole project?

After the project starts, we generally communicate more with the client on the UI design. Generally, these communications are in parallel form, in order to maximize the speed of project advancement. For example, T1: Communicate the UI design of module 1, T2: Communicate the UI design of module 2 + carry out the UI development of module 1… At the same time, we will produce a report for the customer every week to understand the latest progress of the project development. At the end of the project, there will be a period of acceptance stage. If the customer finds any bugs in the finished product during this stage, we will have a specified time to help fix these bugs. If these bugs are not fixed within the time limit, we will compensate according to the rate agreed in advance on the contract.
