syncX: Stock Sync

Well actually in the begining it comes to me like a normal app for stocks sync... but when i go in to deep you can change eveything with formulas... and all the formulas are writing in their support pages..
Also Raj and Azza is very helpfull ; even i bother them with too many questions and issues they helped to me with efficiently...
I suggest you to use this app ( also if you have products too many like me with all variations it is perfect app )
Thanks
