# Products
In Plock, a product represents anything a customer can purchase. This can be a software, a capability, professional services. Products are managed in a single interface allowing you to have a complete overview of your offering.
Products determine two things:
* **The unit metric for the product, that defines how your customers consume the product.** A unit metric can be number of events, storage, number of minutes, number of users etc. The unit metric is defined in a product blueprint, the instruction for how to pull consumption data for the product.
* **How a product is displayed on an invoice.** This includes details like the names on the invoice and the metric for the product. Example, a product named "phone calls" where the metric is a phone call, will have one blueprint. An alternative product is names "Call duration", where the metric is minutes, and it comes with another blueprint.
