To cut that pain in half you can start to treat your startup/idea as if it were a well established business. Think of all the items one company will go through during diligence and make it a habit to implement the proper process accordingly. If your investor walks in and see that you have well run back end they will be impressed and they will not fool around with you. That will also give them some relief. So from the get-go make sure you incorporate properly, hire an accountant firm, or use software and make sure someone records and categorizes every single expense (yeah add 25c for that Koolaid too), develop a great business relationship with your customers (mostly for startups that charge), document your technology ( I do not know much about this one), write short bi-weekly or monthly report about your traffic, write short reports about your sales etc.... You do not have millions in revenue to treat your business like it is, and if you do treat it as if, it is very likely to end up making that much.
