Overview

Lago automatically generates invoices for each of your customers at the end of a billing period (monthly or yearly depending on the plan assigned to the customers). These invoices are generated under the webhook type invoice.created. You can use this webhook to build a proper PDF invoice or to print the information on a webpage.

What are the invoices made up of?

By generating an invoice, Lago displays you all the detailed information about a customer's usage. The invoice is composed of fees (each Billable metric is charged as an invoice fee item) and a total invoice amount.

Several concepts are important to understand while working with invoices:

  1. The taxes: add taxes and VAT to a customer
  2. The fees: invoice items generated and charged as customer's usage
