Re: P&L Report
When a product is added to an order, the current cost price is recorded for that line item.
Order Profit is calculated using these values.
It is tricky to know exact profit if you're selling stock that cost £1 this week, then £1.5 the next and you book these in against the same product.
One way to work around this is to create a new product record if the cost price changes since you last ordered in the stock. Each product record can be linked using a common EAN No, Our Stock Code, Supplier SKU or Manufacturer SKU reference number.
This is however time consuming.
As I said above, we're looking at ways of improving the way this works in a future update.
