Yes. Every Ledger app is a progressive web app (PWA) that works fully offline. Create invoices, take photos, and save PDFs without cell service. Your data stays on your device and is available whenever you need it.
We're building a full suite of invoicing tools: Ledger Drone (aerial spraying), Ledger Haul (trucking), Ledger Bale (hay operations), Ledger Lawn (lawn care), Ledger Forages (silage), Ledger Harvest (combining), Ledger Fertilize (application), and Ledger Farm (farm management). Ledger Drone and Ledger Haul are live now, with more apps coming soon.
General invoicing apps require you to manually set up line items, rates, and units every time. Each Ledger app is pre-configured for its operation — the right fields, the right units, the right workflow. You tap, fill in the job details, and send. And if you already use QuickBooks Online, every Ledger app connects directly — send invoices to your QuickBooks account with one tap. Built for the field, not the office.
