# Introduction

> Sync products from Shopify, create them in Replo, or link out to an external checkout.

Replo lets you import products from different ecommerce platforms and integrate with multiple checkout solutions. You can sync products from **Shopify**, create products directly in **Replo**, or link to external checkouts and booking platforms like **Gumroad** and **WooCommerce**.

## Connecting Shopify to Replo

<Note>
  **Updating an existing Shopify theme**

  Shopify uses themes to define the look and feel of your store. If you're using Shopify and want to use Replo's Shopify-native page building product to directly update your existing Shopify's liquid code, use our [**Shopify Theme Builder**](https://support.replo.app/).
</Note>

The Shopify integration works best for physical products with inventory, fulfillment, and shipping needs, or if your business already runs on Shopify.

When you connect Shopify from the [Integrations app](/apps/integrations), your products, variants, selling plans, and inventory automatically sync into Replo. Customers interact with Shopify's headless cart and checkout; all cart events are tracked in Shopify for accurate analytics.

## Create and Sell Products in Replo

Create and sell products directly in Replo. This works best for digital products, services, and simple catalogs without complex inventory and fulfillment requirements.

When you create products in Replo, payments are processed through Stripe Express. You can enable automatic email delivery to send booking links or access codes for digital files/products or bookable services instantly after purchase.

## Use External Checkout and Booking Platforms

Build landing pages in Replo and connect them to any external checkout or booking platform. This approach lets you use Replo's page builder while keeping your existing payment and booking workflow on platforms like Gumroad, WooCommerce, Calendly, or any other system.

**How it works:** Create your product in the external platform, get the checkout or booking link, add it to a Replo product, and customers redirect to complete purchase or booking on that platform.
