inFlow Inventory supports three types of products. The most common type is the Stockable Product. The Non-Stockable Product type can be used for products which you don't want to keep a careful inventory of. Finally, the Service type can be used for intangible items that you may buy or sell.

Stockable Product – A stockable product is the most common type of tangible product. inFlow will keep a careful inventory of this type of product and where it is stored. Most businesses with use this type for almost all products that they buy or sell.

Non-Stockable Product – A non-stockable product is a tangible product that you may buy or sell, but don't carefully keep track of how much you have available. For example, you may wish to use a Non-Stockable Product for supplies that are regularly used up, like packing materials. This allows you to create Purchase Orders for these supplies and track their receiving status without requiring you to update inventory counts when supplies are used up.

Service – A service is an intangible item that you may buy or sell, for example, selling an extended warranty on your products or hiring a consultant. Inventory is not kept for services, but this type is provided to allow for including services on Sales Orders or Purchase Orders.
