Keep up the hard work, brother! My humble suggestions:
Dont be afraid to solicit feedback (online) from those who gave you the verbal pat on the back.
Look into Quicken, Mint, or other bookkeeping software which will help you automate that aspect of the business. Believe me, I know how it is having your hands on the data like you do now, but software can normally link up to your bank accounts (saves you manually entering, especially if you scale up), has built in reporting/budgeting, and other bells and whistles to help you.
