ILLERBiller can alert you the moment a bill is created, a table is waiting on the kitchen, food is ready, or a bill is settled -- even when the app is in the background or closed.
Before your phone or browser asks for permission, Biller shows a short screen explaining why -- new orders, kitchen tickets, and bill updates. Tap Turn on and the real permission prompt follows immediately; tap Not now and nothing is asked. This screen appears once, the same way on the Android app and the web app.
After you tap Turn on, Android asks "Allow Biller to send you notifications?" Tap Allow and you're done -- the device enrols itself and starts receiving your outlet's alerts.
You only get alerts for the outlet you're signed in to, and only for what your role covers: kitchen staff get preparation alerts, admins also get the daily sales summaries.
After you tap Turn on, your browser asks for notification permission once; after that the same alerts arrive as browser notifications, including when the tab is closed. If you tapped Not now, you can still turn them on later from the bell in the top bar.
Open the bell and switch on Silence notifications. Alerts still arrive and still badge the bell -- only the alert sound is muted. This is a per-device setting.
Nothing was asked or denied -- Biller will offer the intro screen again after a couple of weeks, or you can turn notifications on any time from the bell in the top bar.
Android will not ask a second time, so the bell no longer offers a Register button -- it would not be able to do anything. Turn notifications back on in your phone's Settings › Apps › Biller › Notifications, then reopen the bell.
Switching outlets from the top bar moves your device's alerts to the new outlet immediately -- you only ever get one outlet's alerts on a given device at a time, matching whichever outlet you're currently switched into.
Each alert shows the table or counter and what changed -- "Table 4 is waiting for Kitchen", "Table 4 Delivered", "Table 4 completed with Rs. 420". Tapping one opens the app on the matching screen.
