Something you cannot do manually
Because the lower your cost, the more competitive your prices. Translates to greater sales and greater profits.
Markup prices at cost + % or cost + $ or both. You can markup prices differently for different distributors. You have total control over your selling price.
All products don't ship equally. You can apply shipping markups in addition to price markups to come up with a selling price that takes all costs into account.
If you don't want to sell a product or a product category, you can simply block it and it won't get downloaded to your database.
