How does one put together a breakdown of renovation expenses for a commercial bank loan application? Does anyone know a short and simple way to do this? I must be having a hard time seeing the forest through the trees. Is there a simple way to do this that will look acceptable and professional?

I renovated a duplex and am refinancing it. All the paperwork for the loan is completed except the lender has emailed me a request for a "Breakdown of Renovation Expenses".  I'm trying but it is driving me nuts. Looking at receipts, looking over my QuickBooks account, I know exactly how much was spent on the renovation. However, breaking this down into categories seems impossible to do accurately. Each Home Depot receipt is a mish mash of so many different job categories, often reflecting a dozen different job categories, that is if you can even decipher the receipts codes, which are not user friendly. How do you decide which categories to use? For the most part, I can break down materials and labor. I can break out basics, such as the cost of the new roof, the kitchen cabinets, the flooring, and probably the paint, some plumbing. I can't break down labor into job categories because the contractor charged one price for labor, and some add on fees for extra labor.  For breaking down material expenses, the receipts are too difficult to comprehend due to the use of codes instead of simple English. 

Thank you
