The customer missed his own deadlines and delays payment. What to do?

Question

Freelance

The customer delayed the payment, for my part the software was ready. Landing group. By agreement, I also had to upload content to domains freshly purchased by the customer. There were no domains, and the delay was clearly on his part. The comrade apologized, offered a peculiar term: in a week he provides me with domains with preference, and I upload content with courtesans there. Five days have passed. For some reason, the customer gives me partial management of purchased domains for registration. Domains - without dns. I'm getting a little upset. This bunny complains about the long terms of fulfilling some of his requests on the reg. 3 more days pass. Applications from the bunny are still not processed properly.

Hence the question to experienced comrades: what to do with this goat, and how to get payment from him? The money is good, the advance payment (30%) was received after the mentioned conversation.

Upd: the customer is satisfied with all the content, he considers himself guilty.

Answer 1

If you didn’t give the content, then demand 100%, then give it back. It is unlikely that he will want to lose an advance payment.

Answer 2

Well, since everything suits you, you can ask for another 30% -50% extra. If he does not pay during the day, then you will say that you are blocking the development, you do not answer third-party topics and you are waiting for the domain.

Answer 3

Freeze and wait for access with payment, as correctly said above.
There is no need to scare, it is enough that he considers himself guilty of the delay.

Answer 4

1. Stop working until 100% payment, if necessary, demonstrate the work on your domain.
2. Switch to another job, on demand. :)
