❌ Why Most Self-Employed Struggle With Bookkeeping
You are not sure what counts as a business expense, so you do nothing.
You do not have time to learn QuickBooks, or worse, you tried and gave up.
You rely on your bank statements and a prayer for tax season.
You wait until April, then spend hours scrambling for receipts.
You know you are probably overpaying in taxes, but do not know how to fix it.
You sheepishly dump a shoebox full of old, yellowed receipts on your accountant’s desk at tax time.
This spreadsheet was built to eliminate all of that.

Built by a CPA Who Gets It
I'm Dan Mullen, a licensed CPA and real estate-focused financial coach. I built this spreadsheet to solve a real problem: business owners drowning in receipts, software bloat, or... nothing at all.
This is the exact system I teach in live CE classes for real estate professionals.
And now, it even helps estimate your taxes correctly throughout the year, something most software still gets wrong.
If you want simplicity, control, and tax savings without turning your life into a finance class, you’re in the right place.
One-Time Payment.
No Subscriptions.
Most tools want a subscription for $38 PER MONTH. Ours is $47 ONCE.
One download. Zero overwhelm. Real Estate bookkeeping. No BS. No degree required.
Just 10 minutes a month.
