User guide
Every feature explained in depth — how it works and how to use it well.
Transactions & categorization
The transaction ledger is the heart of GBooks Air — how to add, import, edit, split, and categorize transactions with confidence.
Invoicing
Create professional invoices, apply the right sales tax, generate PDFs, track payment status, and keep on top of who owes you.
Quotes & estimates
Send professional quotes, track their status, and convert accepted quotes into invoices in one click — no retyping.
Receipts & OCR
Snap or upload receipts and let on-device OCR read the vendor, date, and totals — then keep every receipt CRA-ready in the Receipt Vault.
Smart Vendor Rules
Teach GBooks Air your vendors once and let it categorize the repeats — the single biggest time-saver in the app.
Sales tax in depth
How GBooks Air tracks GST, HST, PST, and QST on both sides of your business — collected on sales, claimable on purchases, and reportable at filing time.
Mileage & vehicle deductions
Log business kilometres against CRA's per-kilometre rates, keep the records the CRA actually requires, and claim what you're entitled to.
Reports & dashboards
Profit & Loss, A/R aging, cash runway, sales tax, and the dashboard — what each report tells you and when to look at it.
Customer statements
Send a customer a clean summary of their invoices, payments, and balance — the professional way to nudge a slow payer.
Backups & recovery
Your books live on your device — encrypted backups are how they survive lost laptops, cleared browsers, and everything else. Here's the full system.
Fiscal year-end archive
Close a completed fiscal year: lock the numbers you filed, package the year for your records, and keep your working file fast.
