Well unfortunately it is a plot hole in ESB. He could have paid immediately and return to rebellion or never attempt to do it again. As I said many times on this subject, if Han decided to pay Jabba after 3 years, there is no way Jabba would let him live even if he brought a huge pile of money. As crimelord, keeping ones reputation is the most important thing. A guy who fooled him twice in front of his men, has to be made an example of. There is just no other way.
Yeah, that makes a bit more sense.
