## Overview

Integrating PostGrid into your Stripe application allows you to mail invoices to customers with validated addresses. This guide walks you through installing the PostGrid Stripe App and using the invoice mailing feature.

For verifying customer addresses in Stripe, see the [Stripe Address Verification integration guide](/address-verification/integrations/stripe/index.md).

## Setting up the PostGrid Integration in Stripe

This section will walk you through finding and installing the PostGrid app on Stripe, as well as setting up your PostGrid account in Stripe.

## Installing PostGrid’s app on Stripe

To initiate the integration of PostGrid into Stripe, start by visiting the Stripe App Marketplace. Here, you can locate PostGrid through the search bar. Proceed by clicking on the ‘Install app’ button, then wait for the process to be completed. Upon completion, you will be able to open the PostGrid menu on Stripe:

## Setting up your PostGrid account in Stripe

After installing the PostGrid app, you will be required to create an account with PostGrid if you haven’t already, you can do so on this [page](https://www.postgrid.com/sign-up/). To mail invoices through PostGrid, you must create a ‘Print & Mail API’ account on the PostGrid sign up page. If you also want to verify customer addresses, create an ‘Address Verification API’ account as well:

After installing the PostGrid app on Stripe and creating your PostGrid accounts, you must connect your PostGrid accounts to the PostGrid app. To do so, you can navigate to the app settings on the top right corner of PostGrid’s menu on Stripe, then click on ‘View App Settings’ to navigate to the PostGrid App settings.

In the app settings menu, you will be prompted to login to your PostGrid accounts. Logging in to your Print & Mail API account will connect it to the PostGrid application on Stripe, giving you access to the Invoice Mailing feature. If you also connected an Address Verification API account, you will be able to verify customer addresses too.

## Using PostGrid in Stripe

Once the PostGrid application is successfully installed, you will gain access to Stripe’s PostGrid features, including Invoice Mailing. You can locate PostGrid amongst your list of installed applications. Clicking on it will reveal PostGrid’s main menu.

This guide focuses on using the PostGrid Stripe integration for:

1. **Navigating The PostGrid App on Stripe**
2. **Utilizing PostGrid’s Invoice Mailing feature on Stripe**

## Navigating the PostGrid App on Stripe

Upon clicking on PostGrid’s application, a pop-up main menu will appear as shown below. This menu offers two navigation options: **Customers** and **Invoices**.

The Customers option leverages PostGrid’s Address Verification feature, enabling you to verify the mailing and shipping addresses of either a single customer or a batch of customers. See the [Stripe Address Verification integration guide](/address-verification/integrations/stripe/index.md) for more details.

The Invoices option employs PostGrid’s Invoice Mailing feature, allowing you to mail invoices to your customers with a single click through PostGrid’s software and delivery partner network. This feature lets you concentrate on your core business instead of manually printing and mailing invoices.

The Customers and Invoices options in the PostGrid pop-up menu are synchronized with Stripe’s dashboard menu. Thus, any navigation to ‘Customers’ or ‘Billing’ on Stripe’s dashboard will also reflect in the PostGrid pop-up menu and vice versa.

## Invoice Mailing

PostGrid’s Invoice Mailing feature lets you mail an invoice to a customer with a validated address. To execute this, follow the steps below:

1. Navigate to the Billing section, then to Invoices on the Stripe dashboard, or click on the Invoices option in PostGrid’s main pop-up menu.

2. Choose an invoice that you would like to mail from your list of invoices.

3. PostGrid will open the selected invoice in its pop-up menu. If the invoice has already been mailed, you will see an ‘Invoice Mailed’ message:

4. If the invoice hasn’t been mailed yet, you can click on the Mail Invoice option within the PostGrid menu.

5. Next, confirm the recipient’s address and click next.

6. Enter the sender address

7. Choose your mailing options, such as whether to print in color and whether to use express shipping, then click send to mail the invoice.

8. You can track your mailed invoice on the PostGrid dashboard.

## Summary

The PostGrid Stripe App allows you to mail invoices to customers directly from Stripe. To validate customer addresses before mailing, see the [Stripe Address Verification integration guide](/address-verification/integrations/stripe/index.md).
