Offline billing
Offline Billing Software for Windows and Android
Offline billing software matters most at 7 pm on a Saturday, when the broadband goes down and there are six people at the counter. TripleBill gives you two ways to keep billing without internet — the Windows desktop app and the Android app — and they work differently, so this page says exactly what each one does. The web app in a browser needs internet.

Three ways to run TripleBill, and what works offline in each
| Where you bill | Without internet | Where the data lives |
|---|---|---|
| Windows app, local mode | Everything: billing, stock, purchases, reports, the books | In a database on that computer; back it up from File → Back up data |
| Android app | Billing keeps working; sales queue on the phone and sync when the connection returns | Your online TripleBill account |
| Web app in a browser | Does not work offline | Your online TripleBill account |
The Windows app also has a cloud mode that opens your online account instead; that mode needs internet like the web app.
Windows: the whole app on your own computer
The Windows desktop app is the same TripleBill you see on the web, packed with its own database. In local mode, every screen works with no internet at all: the counter, invoices, purchases, stock, GST reports and the books. Nothing is looked up online while you are offline — no analytics, no update checks.
Because the data sits on that one computer, backups are your job. File → Back up data saves a zip of the whole database in a few seconds, and File → Restore brings it back. Copy that zip to a pen drive or cloud folder at the end of the day and a dead hard disk is an inconvenience, not a disaster.
- Windows 10 or 11, 64-bit
- All features work in local mode without internet
- Backup and restore from the File menu
- Receipts and KOTs print straight to a named printer, no dialog
Android: bill offline, sync later, never twice
The Android app keeps your item list on the phone. When the signal drops, the counter carries on: scan, bill, take cash or UPI, print or share. Each offline sale is stamped with its own id on the phone and queued; when the phone is back online the queue is sent, and the server accepts each sale once even if the phone sends it again after a timeout.
Sign-in needs internet the first time. Lists and reports read from your account, so they wait for a connection and say so on screen.
- Catalog cached on the phone
- Offline sales queued and synced in order
- Duplicate-safe sync: a sale is booked once
- Camera barcode scanning works offline
A worked example: a power cut in a busy kirana
Ravi runs a kirana with one Windows PC at the counter and an Android phone for home deliveries. At 6:40 pm the router dies. The PC is on the Windows app in local mode, so the counter does not notice: it bills 38 customers for ₹14,260 in the next two hours, prints receipts on the 80 mm printer and moves stock as usual.
Meanwhile the delivery boy bills four home orders worth ₹2,115 on the phone with no signal in the lane. They sit in the phone's queue until he reaches the main road, then sync to the online account in the order they were made.
The one thing to know: in this set-up the PC and the phone hold separate books, because the PC is in local mode. Shops that want one set of books on every device use the Android app and the web app (or the Windows app in cloud mode) and accept that the PC needs internet.
Sample figures.
What does not work offline (yet)
- The web app in a browser — it needs internet
- Sync between a Windows app in local mode and your online account; local mode keeps its own books
- Triple AI, sharing on WhatsApp, the online store and QR ordering by guests — they need internet
- Reports in the Android app — they open when the phone is back online
How to set up offline billing in TripleBill
- 1
Pick the device
Use the Windows app for a counter PC that must never stop, or the Android app for a phone or tablet that loses signal now and then.
- 2
Install and sign in once
Download the Windows installer or the Android APK from the download page and sign in while you still have internet.
- 3
Load your items
Add or import your items so they are on the device; the Android app caches the catalog after the first sync.
- 4
Bill as usual and back up
Keep billing through any outage; the phone syncs its queue later, and on the Windows app take a backup from the File menu each evening.
Frequently asked questions
Does the TripleBill web app work offline?
No. The web app needs internet. For offline billing use the Windows app (fully offline in local mode) or the Android app (billing queues offline and syncs later).
Will offline sales on the phone be billed twice when it reconnects?
No. Every offline sale carries its own id from the phone, and the server books each id only once, even if the phone retries.
Does the Windows app sync with my online account?
Not in local mode: it keeps a separate set of books on that computer. Cloud mode opens your online account instead, which needs internet. Choose one per computer.
Which plan do I need?
Mobile and desktop access — the Android and Windows apps — are on the Starter plan (₹299/month, ₹2,999/year or ₹6,999 for 3 years) and Pro. Every new business gets a 7-day free trial with everything unlocked.
How do I back up the Windows app?
File → Back up data writes a zip of the whole database. Keep a copy off the computer. File → Restore from backup puts it back.
Do GST bills made offline count in GSTR-1?
Yes. Offline bills are ordinary numbered invoices. On the phone they reach your account when they sync; on the Windows app they are in that computer's GST reports straight away.
Is there an offline app for Mac or iPhone?
No. There is no Mac or iOS app yet; the web app runs in Safari but needs internet.
