Have a question here that will certainly show how much I dont know..lol..

My broker has a website, Back end office, with IDX Solution/Provider. He is going to change IDX Provider/Solution. He is thinking of having X design his website and have them incorporate the IDX solution in it. However....where does the back end office come in then? Is that part of the actual website design or do you hire an outside source to get code for a back end office?
