Missed Appeal Deadline in Civil Court

I took a client to court for non-payment and the judge found in my favor. However, the defendant filed an appeal with the 30 day window but failed to pay the requisite fees by the due date. Can they attorney attempt to pay those fees now that the date has passed or are they now stuck with the original judgment? Also, what should I do to collect on my judgment if they have no other appeal options? - Is this your question? Add additional information
