Can SambaPOS calculate average cost price based on stock at hand for purchases

Hello everyone, I have a few questions but if they are covered please share links.

  1. I need to know if SambaPOS can calculate average cost price based on stock at hand for purchases, the average is needed to estimate value of stock at hand.

  2. Is there a way to automatically save the currently used cost price entered on the purchase screen when doing purchases, other than editing the default cost for each item in inventoryitems?

  3. How can month end stock take be captured on the system, I know SambaPOS has end of day Records. How about end of month records?

Thank you.
