I am running three store. All the mobile phone repair are performed at store A and all the laptop repair are performed at Store B and store C only deal with selling and booking.

If any mobile phone is booked in store B and C, these phones are sent to store A and all parts are there and they used their own inventory. then once the phone are fixed , they send it back to orignal store.
SAme with laptops.

I want a function in this system that we cannot book a device in different store but can assign to an engineer in the other store or can transfer the job to another store.

This issue comes from not being able to determine in an eye's glance what's going on with a repair job. Right now the only Statuses are "In Process", "Not Fixed", and "Fixed". In our old system we are trying to migrate from, the following statuses were selected from a dropdown for each work order and were changed accordingly as the job status changed:
Open
Closed
Repair Accepted
Repair Declined
Received: Payment
Received: Parts
Received: Device
Order Part
Waiting on Parts
Waiting on Device
Waiting on Pickup
Under Repair
Fixed
Delivered
Contact Customer

This enabled us to go to the LIST view of repair work orders and see the EXACT status of each repair work order in an eye's glance. This was extremely helpful when a customer walked in or called in for staus of a repair job.

Currently with Cellsmart, the only means of finding out the status of a job is first go to list and see it's in Process, then edit that job and hope someone kept up the repair notes manually which usually in our case doesn't happen. We have been acustom to just go change the status from one to another the instant it actually changes because we knew the system would timestamp the time the status was changed and in an instant we could go see where the job is now and how it got here step by step by viewing the status history list.

So I think the way you can make this a simple enhancement is to give the user the same GUI you give when adding a "Repair Issue" ... so this way I can add a "SUB-Status" to your "MAIN statuses" if i want to and, allow me to see the sub-status in the Repair List by giving a setting somewhere that is something like:

___Show Sub-Status as current status

This would be very helpful ... Thanks

The inventory system needs the ability to seel total inventory of all stores includng serialized #. I should not have to log into each store and check inventory and then manually add the totals. CellSmart should have the ability to check the inventory of each location and give the combined total of all locations. It should also have the ability to check the serialized number of product and know exactly which location the serialized item is at. Basically the inventory system needs to be integrated in such a way so that I am able to check inventory of one location or ALL locations at once. Thanks.

The repair system before the major update that changed it was easier to work with: when we hit "Fixed" it popped up with the 3 options (inventory used, no expense, 3rd party). That was the perfect way to do it because it gave us immediate perspective on what to do next to check out the customer the fastest and most efficient way. In the new system we had to go to a different TAB to add inventory (a longer way to do it, and sometimes makes us forget to add inventory - will only remind us when we try to check out which also extends the time of checkout). Please revert the repair system how it was.
