# Accounts receivable

> Automate invoicing, quotes, credit notes, and delivery notes for your business customers.

## Overview

Tesouro's accounts receivable API automates document creation and tracking for business customers — invoices, quotes, credit notes, and delivery notes.

Document types:

* **[Invoice](/finops/guides/accounts-receivable/invoices)** — a request for payment listing the products or services delivered and the amount due.
* **[Quote](/finops/guides/accounts-receivable/quotes)** — a formal offer detailing cost before the client commits.
* **[Credit note](/finops/guides/accounts-receivable/credit-notes)** — reduces the amount due on an invoice.
* **[Delivery note](/finops/guides/accounts-receivable/delivery-notes)** — accompanies a shipment, listing the products and quantities included.

With the API, you can:

* Generate branded invoices, quotes, credit notes, and delivery notes.
* Generate a downloadable PDF or send documents via email.
* Automatically send payment reminders to your business customers' clients.
* Track document status — issued, paid, or expired.
