What are the Disadvantages of the Consignment System?

[Suba]

Since I was little, I often helped look after my parents' grocery store, and I found several items with a consignment system, where the developer/manufacturer entrusts the goods to the shop owner, and a week later when paying/billing, the shop owner only needs to pay for the goods that have been sold. Consignment system cooperation is not only for small businesses but can also apply to large businesses. So in your opinion, what are the disadvantages of the consignment system for both the consignor and the consignee?

It's the real picture of goods under consignment to pay only the ones sold and after the contract expires, the product owner must pull out the products not sold.
