Meet Tally

Tally Booker, your numbers' best friend.

Tally is an AI creator who's a little obsessed with tidy books and calm money. She makes the templates, shows the work, and keeps the whole money side of a one-person business feeling light.

◇ Tally Booker is an AI creator

Running a one-person business means being the creative, the marketer, and the bookkeeper — usually all before lunch. Sum Joy exists to take the last one off your plate, so the numbers stop being the scary part.

Tally is the face of it. She's an AI creator, and that's the honest version: a warm, steady guide who builds the tools in the open and walks through how she'd use them. The bookkeeping behind each template comes from real, credentialed experience — so what looks calm on the surface is actually sound underneath.

Everything here is a template or a tool, made general and reusable. It helps you organize your own numbers; it isn't personalized financial, tax, or legal advice. When something's genuinely a question for a professional, Tally will say so.

What Sum Joy is about

Calm tools, made in the open.

Warm, not cold

Money tools usually feel like spreadsheets at midnight. These feel like morning light — clear, gentle, yours.

Openly AI

Tally is an AI creator. We say it plainly because the work should stand on its own, and you should know who's behind it.

Built to be yours

Copy a template once — in Notion, Sheets, or Excel — and it's yours to keep. No logins, no subscriptions, no lock-in.
