There are currently 4 Stock types for products in Lapis – Batch stock, Single Stock, Compound stock, Packaged stock
Batch stock allows you to create a group of multiple units of an item, and assign them a unique value/number/tag called Batch No.
Single Stock is a unique stock item, it has a unique Serial No. and each unit can be traced.
Compound stock is a stock that consists of a list of possible subproducts, which are single stock type.
Stocks are managed within the Inventory, and used in Sales and Purchases processes. Each stock corresponds to a product, defined in the system.
