WinSale Data Collector is a barcode scanning app for the Netum Q500 handheld device. Scan items to build inventory lists and export them as text files compatible with WinSale software.
Scans are recorded with a quantity of +1. Use this when receiving or counting stock. Exported as winsale.txt.
Scans are recorded with a quantity of −1. Use this when removing or selling items. Exported as negative-qty-winsale.txt.
Switch between tabs freely at any time. Each tab maintains its own independent list — scanning in one tab never affects the other.
Tip: The banner at the top of the screen shows which mode is active — blue for Inventory, red for Reduce Inventory. Glance at it before scanning to confirm you're on the right tab.
Removes the most recently scanned item. A confirmation dialog will appear asking you to confirm before deleting. Use this if you accidentally scanned the wrong item.
Permanently deletes every scan in the current tab's list. A confirmation dialog will appear showing how many scans will be deleted. This cannot be undone. The other tab's list is not affected.
Generates the text file and opens Android's share sheet so you can send it via email, Bluetooth, Google Drive, or any other app. See Section 04 for file format details.
Data is saved automatically. You do not need to export before closing the app. All scans are stored on the device and will still be there when you reopen the app. Only Clear All permanently removes them.
Each exported file is a plain text file with one scan per line in the following format:
The barcode number scanned from the item.
1 for Inventory scans, -1 for Reduce Inventory scans.
The date the item was scanned, in MM/DD/YYYY format.
Files use Windows-style CRLF line endings for compatibility with WinSale software.
One line per scan. If you scan the same barcode 10 times, the file will have 10 separate lines — it does not combine or sum quantities. This matches the format WinSale expects for import.
Tap ↩ Delete Last immediately after a bad scan. It removes only the most recent entry. Confirm the deletion in the dialog that appears.
Tap 🗑 Clear All and confirm. This wipes only the current tab. Switch to the other tab and repeat if needed. Exporting first is recommended as a backup.
After tapping 💾 Export, Android's share sheet will open. Choose an app to send the file — email, Google Drive, Bluetooth, USB transfer, etc. If the share sheet does not appear, check that the app has storage permissions in Android Settings.
