WinSale Data Collector

Netum Q500 · Android App · v1

The Two Modes

WinSale Data Collector is a barcode scanning app for the Netum Q500 handheld device. Scan items to build inventory lists, then export them as text files compatible with WinSale software.

📦 Inventory Tab

Scans are recorded with a quantity of +1. Use this when receiving or counting stock. Exported as winsale.txt.

📉 Reduce Inventory Tab

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.

Scanning Items

Open the app and make sure you are on the correct tab — Inventory for adding stock, Reduce Inventory for removing it.
Point the scanner at the barcode on the item and press the scan trigger button on the Q500 device.
The item appears instantly at the top of the list showing the UPC, quantity, and today's date.
Repeat for each item. Every scan adds a new line — duplicate UPCs are each recorded separately, one line per scan.

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.

The Button Row

↩ Delete Last

Removes the most recently scanned item. A confirmation dialog will appear before deleting. Use this if you accidentally scanned the wrong item.

🗑 Clear All

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.

💾 Export

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.

Export File Format

Each exported file is a plain text file with one scan per line in the following format:

winsale.txt — from Inventory tab

068113117586,1,02/27/2026
012345678901,1,02/27/2026
068113117586,1,02/27/2026

negative-qty-winsale.txt — from Reduce Inventory tab

068113117586,-1,02/27/2026
012345678901,-1,02/27/2026

Column 1 — UPC

The barcode number scanned from the item.

Column 2 — Quantity

1 for Inventory scans, -1 for Reduce Inventory scans.

Column 3 — Date

The date the item was scanned, in MM/DD/YYYY format.

Line Endings

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.

Tips & Troubleshooting

Scanner not registering scans

Make sure the app is open and in the foreground.
On the Q500, open the Scan Code Settings app and ensure Send Broadcast is turned ON.
If broadcast mode is off, the scanner acts as a keyboard — the app still works but requires the screen to be active.

Scanned the wrong item

Tap ↩ Delete Last immediately after a bad scan. It removes only the most recent entry. Confirm the deletion in the dialog that appears.

Need to start a fresh session

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.

Export file not showing up

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.
