Penny
Your CFO

Penny keeps your books
so you don't have to.

Most founders fly blind on the numbers, or pay for software and a bookkeeper they never use. Penny already sees the money moving through your company — so she keeps a real P&L, margin, and runway on her own, and tells you what it means.

What Penny does

Real books, automatically

A true profit & loss and per-product margin from your actual sales, costs, and fees — nothing to connect, no spreadsheets.

Cash & runway

Tell her your cash on hand and she shows how long it lasts, and flags when you're spending more than you make.

A CFO's read

Plain-language advice: "thin margin on this product," "you're profitable — reinvest," "raise or cut before you run out."

She handles sales tax, too

Sales tax is the compliance landmine small sellers step on most. Flip one switch and Penny collects the right tax on every sale — calculated per the buyer's address, itemised on the receipt — the moment you're registered. She won't ever break your checkout to do it. She never invents a number: what's known is fact, fees are marked estimated, and what only you can know is yours to enter.
