There is a way to Sync your data from POS to the CAS using the Send to CAS buttoninstead of only syncing the POS from CAS
Now you have the option of Sending data to CAS or Getting data from CAS.
You have the option of either syncing Master Table or Transactional Data
Syncing your transactional data can be very dangerous because you can potentially lose all you transaction data. So we recommend that you contact support before you try Syncing your Transactional Data.
Syncing data does not UPDATE existing data, it only inserts NEW data, such as a brand new item that does not exist on your POS.
To get updated item information like cost price or other details, change the name of the Item on CAS and all UPDATED information will push to the POS system for that item.
