I'm Jeff, a high school business finance teacher in Ohio. When my family started helping an aging parent with money, the hardest part was not the math. It was keeping a clear record. The Proof Book is the set of spreadsheets and printable pages I wish we had on day one. Proof of every dollar, ready if anyone asks. Not what you expected? Email hello@theproofbook.com and we'll make it right. Record keeping templates only. Not legal, tax, or financial advice. The Proof Book is a trade name of The Chalk and Ledger Group LLC.
