JamInvoice is professional, offline-first invoicing and estimating software for freelancers, self-employed professionals, tradespeople, small businesses, and contractors who want fast, professional documents without complicated software.
JamInvoice is currently in a limited Early Access phase for Windows and Android. Join Early Access below to start using it today. iOS and macOS are planned for a later stage.
Early Access means we're inviting a limited number of business owners to test JamInvoice before its public launch. It's temporary — we're using this phase to test, refine, and improve the app based on real feedback before launching more broadly.
After Early Access, JamInvoice is planned to launch publicly as a subscription service. Pricing and any free-trial details have not been finalized and will be announced closer to public launch.
Yes. Your core business data — clients, invoices, and company records — is stored locally on your device, and JamInvoice is designed to work without an internet connection.
Local Folder Sync lets you point JamInvoice at any shared folder — including one managed by Dropbox, OneDrive, or Google Drive — so your data merges automatically across devices with no server involved. It's available now. Direct Google Drive and OneDrive integrations are currently in Beta Preview.
JamInvoice currently requires approximately 75 MB of storage after installation on Android. Because JamInvoice is offline-first, your core business data is stored locally on your device, and additional storage is used as you create documents and save files.
Windows and Android are available now in Early Access. iOS is planned for a later stage.

Follow our development progress as we build the ultimate offline-first invoicing ecosystem.
JamInvoice started from a simple idea: small business owners deserve invoicing software that respects their time, their data, and their independence.
We're building a fast, offline-first solution that gives users full control over their data, keeping your financial records exactly where they belong—on your own hardware.
