1) Hi, I'm planing to buy your POS system soon, I can see that there are lot of number of modules. If I want to buy a system with all your features what is the system should I buy? Is that Stock Manager Advance with All Modules ?

2) I have optical sale and there are 2 major products. spectacle frame and spectacle glasses. I maintain frames in my stocks and glasses always purchase from outside suppliers base on customer prescriptions, Since I need to issue an invoice for customer upon their visit, I can only select AVCO method to issue glasses ( since no stock in the system ) But as soon invoice issue to customer, I can make a purchase order for my glasses supplier as matching to issued stock, ( I can track it from Quantity alerts)

My problem is I have noticed that once issue an invoice like this, today profit section in POS show all minus figures, It show some wrong numbers . It cannot be fixed even if I place an purchase order for minus qtys.

Any advise for resolve this issue ?

Thank you.
