Offline-first · Browser · Android
Invoices drafted on your device, paid directly to your bank.
Create professional invoice PDFs in seconds with instant UPI QR payments and direct links. Works without an account, completely on-device.

Why keep your invoicing offline
Cloud accounting tools lock your client records behind subscription portals and freeze when your connection drops. Sento runs directly on your device.
Tools for independent work
Everything needed to generate professional billing documents and track client balances without subscription lock-in.
Built on high-performance local SQLite. Instant search, instant calculations, and zero waiting for spinning wheels.
Embed your UPI QR code or direct payment URL (Stripe, PayPal, UPI) on every PDF so clients pay immediately.
Choose between Standard, Modern, Classic, and Minimal layouts with custom branding, business logos, and signature pad.
Save clients, track outstanding balances, view invoice histories, and import directly from device contacts.
Secure sensitive billing and financial figures behind device-native fingerprint or Face Unlock authentication.
Export passphrase-protected backup archives or sync safely across your devices using authenticated Google Firebase.
Android application
Runs fully offline with on-device SQLite storage. Launches instantly without network roundtrips or login walls.

Profile configuration
Business details, tax identifiers, currency, and payment details saved locally.

Invoice management
Track draft, sent, and paid statuses with single-tap PDF exports.
How it works
Draft, customize, and deliver client-ready invoices in three steps.
Set up your business
Enter your trade name, address, tax/GSTIN number, logo, and preferred payment link or UPI ID once in your profile.
Draft invoice in seconds
Pick a client, type line items with automatic tax and discount calculations, and choose your preferred PDF template.
Share & collect payment
Send the clean PDF directly via WhatsApp or email. The client scans the embedded QR to transfer funds straight to you.
Built around local privacy
Billing software should not inspect your revenues or monetize your client book. Review our privacy policy for full disclosures.
Invoices, client addresses, and financial amounts reside in your device SQLite database. Nothing uploads unless you choose to sync.
No advertising libraries, no data brokers, and no tracking scripts. Your client records stay between you and your client.
Cloud backup is user-authenticated via Google Firebase Firestore with strict per-user access rules. Passphrase backups can be exported anytime.
Honest pricing without recurring lock-in
Start completely free on web or mobile. Upgrade when you need cloud backup and unwatermarked multi-template layouts.
