▶Bill it. Track it.
Open one file. Log the workbook you bought for a student, the miles you drove to their kitchen table, the software you pay for — and see in one place what to bill a parent, what you were reimbursed, and what you get to write off. No spreadsheet, no subscription, no signup: one HTML file that opens in any browser and keeps every number on your own computer.

A spreadsheet makes you build the mileage math, the category totals and the year-end summary yourself — then maintain the formulas.
Tag an expense billed-to-parent and it rolls into what a parent owes you — materials and travel stop coming out of your pocket.
Every expense and mile lands categorized, so tax time is an export, not an archaeology dig.
Round-trip doubling and your mileage rate are automatic — and past years keep the rates you logged them at.
Everything lives in your browser on your machine. JSON backup out, JSON backup in. Nothing is uploaded, ever.
No formulas to build or break — it's a finished app. Double-click index.html and start logging.
Unzip the download — there's no install
Double-click index.html; it opens in any browser on Mac, Windows, Chromebook, iPad or Android tablet
Set your mileage rate once in Settings
Log expenses and drives as they happen, tagging what's billed, reimbursed or deductible
At tax time, open Tax Summary and export CSV or print to PDF
A spreadsheet makes you build the mileage math, the category totals and the year-end summary yourself — then maintain the formulas. This is a finished app. It's also the designed companion to our Tutor Rate & Schedule Planner: bill the parent for materials and travel there, then track those same costs for your own taxes here — though it stands completely on its own.
As soon as your order is complete you get instant access to download the app — one HTML file that runs in any modern browser (Chrome, Safari, Edge, Firefox), on Mac or Windows, completely offline. No install, no login, no subscription; your data stays on your device.
Nothing to install and nothing to configure — double-click the file and it opens in your browser. Available in English.
No. Unzip and double-click index.html — it opens in any browser on Mac, Windows, Chromebook, iPad or Android tablet.
In your browser, on your device. Nothing is uploaded. Export a JSON backup any time and import it on another computer.
No — it stands on its own. It's designed as the planner's companion (bill in the planner, track for taxes here) if you have both.
No — it's an organizing tool. Deduction rules vary by country and situation; confirm specifics with a qualified tax professional.
No subscription, no account, no ads. One-time purchase; updates arrive as a download link, no re-purchasing.
Because delivery is instant, all sales are final — but message us with any issue and we'll make it right.
