# How Invoices Work

> Understand invoice statuses, learn how to create and send invoices, and track customer payments from your Bila Product Store.

Create professional invoices, send them to customers, and track their payment status from your Product Store. Invoices are denominated in ZMW and customers pay via mobile money from a public payment link.

<Info>
  Invoices are part of your **Product Store**. Make sure your store is active and accepting orders before sending invoices.
