Sell the same product by lot or by piece

You can now sell one article both as a lot / carton and as a piece, with independent prices.

• Product setup: enable package sales on the product or each variant, set the package name (e.g. كرتون 100), the factor (1 lot = N pieces), and a package sale price separate from the piece price.
• Sales documents: on quotations, orders, delivery notes and invoices, switch a line between Package and Piece. Quantity 1 on a lot of 100 deducts 100 pieces from stock; the BL shows the package label under the product.
• Point of sale: the same Package / Piece choice is available on cart lines, with the matching price, and stock is always moved in pieces.
• Stock stays exact: on-hand quantity remains in pieces only. “Lots + pieces” is a display, never a second stock figure.
