The Barcode Scan App for Exact Online does not work offline: an internet connection is always required. The app is linked to Exact Online in real time through the official API, so every scan is booked into your administration immediately. There is no offline mode, so without a connection you cannot scan or book. This page explains what that means and how to ensure a reliable connection.

Do I need internet to scan?

Yes. Because the app communicates directly with Exact Online, a Wi-Fi or mobile data connection (4G/5G) is required. As soon as you scan a barcode and confirm the booking, the goods receipt, order pick, transfer or count is processed straight into Exact Online. That keeps your stock accurate in real time, without a separate synchronisation step.

What happens if the connection drops?

If your connection drops, for example in a dead spot in the warehouse, the app shows a warning. At that moment you cannot send bookings to Exact Online. Wait until the connection is restored and then continue scanning. This prevents bookings from being lost or processed twice.

Can I install the app on my phone or scanner?

Yes. The Barcode Scan App is a web app (PWA) that you can add to your home screen from the browser, so you open it with a single tap. For Android the app can also be installed from the Google Play Store. Note: installing makes access faster, but the app still needs an internet connection to work with Exact Online.

Tips for a stable connection in the warehouse

  • Ensure good Wi-Fi coverage everywhere you scan; add extra access points or Wi-Fi extenders where needed.
  • Consider mobile data (4G/5G) as a backup for areas with poor Wi-Fi.
  • Test coverage in advance at the busiest picking and receiving locations.
