Overall, everything went quite well. As in the previous time, communication was easy, the client was always in touch, and quick responses were provided when details needed clarification. And it was like that almost until the end of the project. During the work on the project, I showed the client the results on my server at certain stages, and edits were made if necessary.
Then, when I transferred the files of the finished website to the client on the exchange + placed and configured the site on his server, he initially had questions, then they turned into wishes, and then somehow into a demand (not in direct text, but the client was in a hurry to finish the project without any questions about the site anymore).
This question concerned future changes to the site, and I provided certain recommendations on how it could be done most easily. However, the client expressed a desire for me to share all my developments with him, to which I refused because it was not stipulated in our previous agreements.
I also offered the client an alternative solution for implementing his new "wish," which required some time and a bit of additional budget. The client accepted the proposal, opened an additional project (without closing the current one), but during the day, he drastically changed his mind, closed the additional project (which we hadn't managed to launch), and also closed the current one, leaving not a very good review with corresponding ratings (I remind you that until the complete transfer of the project and its placement on the client's server, everything was fine).
Of course, I inquired with the client about what had changed in his position, but he simply remained silent and only on the 5th day gave a short response, without any specifics.
This is the first time I am writing such a long review, and I hope it will be the last. And most likely it would have been good and concise if it weren't for this misunderstanding at the end of our collaboration.
I hope this is just a one-time case that will give Oleg and me additional experience for future projects. Because it's a pity to transition from normal business relations into a state of misunderstanding and some kind of ambiguity.
