Another enforcement mechanism that may be available is to go back to the court and get an order to transfer the money out of their bank account, then present it to their bank and they will do it.

Assume that all the avenues a company has to enforce debts against you, you also have those avenues to enforce debts against a company. It just usually doesn't happen that way around, in practice.

You go after their bank account, which is a slightly different procedure.

The main headache is finding their bank account. The best way to do this is to find someone they pay and seeing what source account was used.
