Sometimes it becomes necessary to work with an unfamiliar client and the last stage takes place on his server. How can you insure against dishonesty - just in case. Maybe it's paranoia, but sometimes it's better to be safe than sorry. Perhaps there are some developments, share. Maybe you can somehow connect to the database on your server, etc...

Take payment for the previous stages and an advance payment for this one.

Depending on what we are talking about:
