- Filter by counted, uncounted, or recount items
- Add existing or unknown products
- Scan barcodes to count or add products
- Review scan history in the history panel
- Configure scanner settings
- Review products marked for recount in GTX
To use mobile stocktakes, additional functions must be enabled in your GTX system.
To enable mobile stocktakes in your GTX system, please contact the Megabus Support Team.
Initialising Mobile Stocktakes
If there is no active stocktake in GTX, the Stocktake module will display a pop-up prompting the user to initialise a new stocktake.

To initialise a mobile stocktake:
- Select the Mobile Stocktake option
- Click Ok

Product lists can be broken up and assigned to different counters, when using mobile stocktakes.
In the Manage Recorders to Initialise pop-up that opens:
- Tick Included in Stocktake next to each counter that will count products
- Click the Products... button next to a counter
In the Add a range of items to the Stocktake List pop-up that opens:
- Select an option under Select Products by
- Enter the From and To range
- Click Ok

These products will be added to the stocktake list and will appear in the mobile Stocktake app for the assigned counter (and not any others).
To assign products to additional counters:
- Click the Products... button next to the next counter
- Select a different product range
- Click Ok
Once all counters have been assigned products:
- Click Initialise.
Assigned products will not appear in the Stocktake module of the mobile app (and it will not open), unless the logged-in user has also been included in the stocktake.
Once initialised, all users logged into the GTX system in the app will see the mobile stocktake when they open the Stocktake module.
**If you have multiple stock locations: **
- Mobile stocktakes need to be need to be performed for them one at a time
- Stocktakes for multiple locations cannot be performed all together or at once
The number of counts assigned to each counter can be checked by clicking on the Manage Recorders button
at the top of the module window.
Currently, there is a bug where you have to tick the selected counter then close and re-open the manage recorders window before it will update the assigned counts
