Issuing Gift Voucher / GC workflows from Retail POS

How it works :

1. POS sell GC and stores into a local database with a value $0

2. POS sends the data to Head Office with value of $0 and Head office create GC with value of $0

3. POS finalize the payment and complete

4. POS sends the data to Head Office with the value of payment $xx (GC value)

5. Head Office received data, create GC movement and update GC with value $xx

6. With schedules running in POS every x minutes, POS will update the GC created in No 1 with data from Head Office (GC value $xx)
   
   If the store whiches to see the update without waiting for the schedule on POS running, use Menu: Refresh Data

7. This may take 5-10 mins to run because it also updates product, customer, etc data
