How to count stock

  1. Start the camera on your phone, or plug in a USB or Bluetooth barcode scanner and click in the box under the camera.
  2. Scan each item. The same barcode adds one each time. To count a case of 12 in one scan, set Each scan adds to 12.
  3. Fix mistakes with the − and + buttons, or type the quantity.
  4. Download the CSV and open it in Excel, Google Sheets or your inventory software.

Built for real stockrooms

  • Works with hardware scanners. USB and Bluetooth scanners type the code and press Enter, which this page counts straight away.
  • No double counts. The camera counts the same barcode again only after it has left the picture for a moment, so holding still never adds extra. Move from one item to the next and each one counts.
  • Several counts. Name each count (by date, shelf or location) and switch between them. They're kept in this browser until you delete them.
  • Offline. Install the page as an app and it opens without a connection, for stockrooms with poor signal.
  • Private. Your counts stay on your device. Nothing is uploaded.

The CSV

Each row has the code, the barcode type, the quantity, and when it was first and last scanned. Excel removes leading zeros from numbers like UPCs when it opens a CSV; to keep them, use Data → From Text/CSV and set the Code column to Text, or open the file in Google Sheets.

Tips for a faster count

  • Work shelf by shelf, and name each count after its location.
  • Count full cases with Each scan adds set to the case quantity, then switch back to 1 for loose items.
  • For items with no barcode, print your own with the inventory barcode generator and stick them on the shelf edge.
  • Counts are saved in this browser only. Download the CSV before clearing your browser data or switching devices.
