The following requirements must be fulfilled before a product can be purchased.
Inventory requirements
A product must have available stock in a warehouse, regardless of whether the marketplace or the seller manages it.
The quantity of stock must be enough to meet customer demand.
Product requirements
The product must be assigned to a category.
The product’s visibility settings must support its availability in the storefront.
If the product requires approval, it must be reviewed and approved by either the marketplace operator or a staff member with the right permissions.
Seller requirements
Sellers must accept the marketplace's agreement for their products to be listed and available for sale.
Sellers must confirm their agreement remains unchanged by the marketplace, because any modifications will cause their products to be temporarily removed from the storefront.
If a seller account changes its primary contact, the seller's products are immediately removed from the storefront. Those products will only reappear on the storefront once the new seller contact accepts the marketplace's seller agreement.
