Self-Employed Bookkeeping on a laptop and on a phone

No formulas to break. No subscription.

A bookkeeping spreadsheet means typing every bank line by hand, guessing what to put aside for tax, and one pasted cell breaking the totals. This reads your bank’s file, sorts it by your rules and works out the quarterly estimate — offline, on your own computer. Estimates for planning; confirm with a tax professional.

Questions

Something else? Email us and we'll answer before you buy.

Where is my data stored? Is it private?

Everything is saved inside your browser on this device. Nothing is uploaded and there is no account, so no company holds a copy of your books. They are not encrypted, though: anyone who can use this device and browser can open them, so keep the device locked. Download a backup regularly (Settings → Data & backup → Back up now) and keep it somewhere as safe as the records themselves.

Does it work without internet?

Yes. Open index.html and it runs fully offline. You can also host the folder on any website and choose “Install app” in Chrome or Edge to get a desktop or phone icon that works offline.

Can I use it on my phone or iPad?

Yes. The layout adapts to phones and tablets with a bottom navigation bar. Each device keeps its own data, so use Back up / Restore to move records between devices.

How do I start fresh after trying the sample data?

Go to Settings → Data & backup → Erase records. Every sample record is removed, the 21 starting categories are put back, and the sample’s home office, odometer and mileage settings are cleared, so nothing of theirs stays in your books. Your business profile and other settings are kept.

Does it work out my tax or file my return?

No. It keeps your books and gives estimates for planning, with the working shown, so you know roughly what to put aside and pay each quarter. It does not prepare or file a return. Confirm what you owe with a tax professional.

Does it connect to my bank?

No, and it never asks for a bank login. You download a CSV file from your online banking and import it; the file is read on this device and nothing is uploaded.

My bank’s file looks different. Will it import?

Most will. The importer reads commas, semicolons or tabs, finds the heading row (or works without one), and handles one signed amount column, separate money-in and money-out columns, or an amount with a debit/credit column. You see a preview and can change any column before importing, and the layout is remembered for that account.

Can it make invoices?

No. It records income when you are paid, whoever sent the invoice. For quotes, invoices, stock and point of sale, our Small Business Manager is built for that.

Where do the mileage rates and the Social Security wage base come from?

They are pre-filled from the figures the IRS and the Social Security Administration published for each year, marked “check for your year”, and you can change any of them. For a year not yet published, the latest one is carried over and flagged until you enter the new figure.

I also have a job. Does that change the estimate?

It can. On the Estimated tax page, enter the Social Security wages from your job for the year. They use up part of the Social Security wage base, so less of your self-employment profit is charged the 12.4%.

Is it only for the US?

The categories, Schedule C lines, 1099 forms and estimated tax dates are American. You can change the currency and keep your books in it, but the tax planner follows US rules.

Can several people use it at the same time?

No. It is made for one person on one device, and records do not sync between devices. To move to another device, save a backup and restore it there.

Can customers book or pay online through it?

No. It runs offline on your own device, so there is no booking page for customers and it does not take card payments. You record bookings and payments in it yourself, including ones taken by phone, card reader or another website.
