A bookkeeping app that keeps its nose out of your business.
Your books stay on your device
There's no backend and no login. GBooks Air runs client-side in your browser and stores everything locally, so there's no central database of small-business financials sitting somewhere waiting to be breached. There's simply nothing to breach.
GST, HST, PST, and QST, done properly
Current CRA rates for every province and territory, mileage rates that update on schedule, and expense categories lifted straight from the T2125. Your year-end P&L ends up looking a lot like your tax return, because it basically is one.
Receipts and rules do the typing
OCR reads your receipts on-device. Vendor rules learn your regulars after you've categorized them once. Most people find their bank import arrives already 80-90% sorted before they've touched a thing.
Import a bank CSV, even the ugly kind.
Most Canadian bank exports just work. TD's headerless files, banks that split debits and credits into separate columns, dates in three different formats depending on who exported them — the Smart-Mapper figures it out and shows you a preview before it saves anything, so you can catch a bad guess before it becomes bad data.
- Catches duplicates when your exports overlap
- Works with every major Canadian bank's export format
- Full manual control whenever you want it
Snap a receipt. Skip the typing.
The OCR engine reads the vendor, date, subtotal, and tax straight off a photo, entirely on your device — nothing gets uploaded anywhere. Pair a merchant with a vendor rule once, and the next twenty receipts from that vendor categorize themselves.
- Runs locally; your receipts stay yours
- Reads the GST/HST line so your credits are accurate
- Feeds straight into the CRA-ready Receipt Vault
AES-256, a recovery key, and your own Google Drive.
Storing your books locally only works if you can actually get them back when something goes wrong. One-click backups are encrypted with AES-256-GCM and come with a recovery key, so a spilled coffee or a dead hard drive is an annoyance, not a small-business-ending event.
- Bank-grade AES-256-GCM encryption
- A hex recovery key in case you forget your passphrase
- Optional sync to your own Google Drive
