A facility for specifying the distribution of products and generating product distribution lists. The facility receives account definitions, which may include information specifying account hierarchies. One or more product categories may be associated with each account. A distribution code may also be associated with the account's category assignment. The facility may identify or more products associated with the account, and a product distribution code may be associated with each product in the category. Based on the distribution level for each category and the product distribution codes for each product in the category, the facility may identify products for a product distribution list associated with an account.
