Imagine you own an antiques store in your hometown. One day, a genie pops out of the lamp you’re cleaning and offers to replicate your storefront in five neighboring towns.
But there’s a catch—the stores won’t talk to each other, so you’ll have to drive back and forth to reconcile orders and inventory levels. Do you take the genie up on his offer?
If you sell products through multiple online marketplaces, you’re familiar with this dilemma. You won’t need to physically drive between storefronts, but you will need to devote a lot of time to maintaining consistency across multiple unconnected sales channels.
Marketplace integration is a better option. Here’s how to use it to efficiently sell on multiple marketplaces so you can reach new customers and boost sales.
What is marketplace integration?
Marketplace integration is the process of synchronizing inventory and product data between your online store and marketplaces like Etsy, Amazon, and eBay to make multichannel selling easier. Marketplace integration software consolidates data from different platforms to keep inventory levels up to date, saving time, ensuring consistency across sales channels, and simplifying inventory and order management processes.
How to get started with marketplace integration
- Decide which marketplace to integrate
- Choose your source of truth
- Select marketplace integration software
- Connect your marketplaces
Ecommerce integration can streamline operations for multichannel ecommerce businesses, allowing you to sell on more channels without massively increasing your workload or error risk. Here’s how to get started:
1. Decide which marketplaces to integrate
Take stock of the online marketplaces you currently use and research any additional marketplaces you may want to join in the future. Amazon, eBay, Etsy, and Walmart are all popular marketplaces.
Commission structures, audiences, seller rules, and popular product categories vary by marketplace, so evaluate each of these aspects when considering new sales channels for your business.
2. Choose your source of truth
Next, you’ll decide which platform you’ll use as your primary source of truth—your ecommerce store or a marketplace integration service. In most cases, this will also be where you manage orders and inventory.
If your ecommerce platform provides a comprehensive set of inventory and order management features and most of your sales channels integrate directly with your site, you might use your online store as your source of truth. In this case, you’ll use marketplace integration software to transfer data from other sales channels to your store’s back end.
Many platforms offer one or more native integrations. Shopify Marketplace Connect, for example, allows business owners to integrate their online stores with Amazon, Etsy, Walmart, eBay, and Target Plus. Additionally, the Shopify App Store offers a variety of marketplace integration apps.
If your ecommerce platform is limited or you only sell on marketplaces, you might instead look for a marketplace integrator designed to replace an ecommerce website’s inventory and order management system. These tools consolidate data from different channels, allowing business owners to manage connected sales channels from the marketplace integrator’s centralized dashboard.
3. Select marketplace integration software
Next, choose your marketplace integration software. Start by researching your ecommerce platform’s native tools, then consider third-party tools if one or more of your marketplaces won’t directly integrate with your ecommerce platform.
Consider the following:
-
Features and type. If you plan to use a marketplace integrator as your central source of truth, choose a tool with a user-friendly dashboard that allows you to manage inventory, track order status, and update product listings across channels. If you’ll use your ecommerce site’s dashboard, look for tools that can pull necessary information into your site’s back end.
-
Compatibility. Review compatibility with your site and marketplaces. Many businesses use multiple ecommerce integration tools, but the fewer tools you have to manage, the easier the process will be. Look for tools that do double-duty where possible.
-
Cost. Marketplace integration software costs vary widely, with some offering introductory rates ranging from $10 to $30 per month and others operating on a commission structure. Many platforms also offer multiple pricing tiers, allowing you to scale up as you add new marketplaces or increase sales.
-
Customer support. Quality customer support can streamline the process of integrating tools and help you troubleshoot issues as they arise. Review support options, and select a platform that offers your desired level of support.
4. Connect your marketplaces
Once you’ve chosen your marketplaces and integration tools, sign up for marketplace seller accounts (if you have not done so already) and connect each account to your market integration software. Exactly what this process looks like will depend on the tool, your ecommerce platform, and your chosen marketplaces.
If you’re using Shopify Connect, for example, you’ll download the Shopify Marketplace Connect app and connect your marketplace accounts directly from your Shopify Admin.
Some tools offer AI and machine learning technology that can automatically reformat listings and optimize them for different marketplaces. If your chosen tool doesn’t include this feature, you may need to manually reformat listings according to each marketplace’s specs.
