How to Sync Inventory Between Shopify and Etsy (Complete Guide)

Do you also have two stores running, one on Shopify and another on Etsy?

Sounds like a win. Isn't it?

Twice the visibility, twice the chance to sell.

But here’s what nobody tells you, unless your inventory is in sync, it also means twice the stress.

One necklace sells on Etsy, and before you even notice, someone else has already bought it on Shopify. Now you’re stuck apologizing, refunding, and hoping that bad review doesn’t follow you around.

The fix isn’t more spreadsheets or late-night updates, it’s connecting both platforms so they talk to each other in real time.

That way, you sell once, stock reduces everywhere, and your business finally feels like one operation instead of two competing stores.

Why Syncing Inventory Between Shopify and Etsy Matters

When you sell on both Shopify and Etsy, every order affects the same pile of stock.

If those platforms aren’t connected, it’s only a matter of time before the numbers don’t match.

A product might sell out on Etsy, but still appear available on Shopify and the next order that comes through is one you can’t actually fulfill.

That’s where the real cost shows up, refunds, awkward emails to customers, and poor reviews that hurt your brand.

Beyond overselling, manual updates also eat into your day. Instead of focusing on new products or marketing, you end up spending hours fixing stock levels across two dashboards.

By keeping your inventory synced, you remove that risk. Stock adjusts instantly no matter where the order happens, customers see accurate availability, and you get back the time and confidence to grow both stores without worrying about mismatched numbers.

Does Shopify Natively Sync with Etsy?

The short answer is no, Shopify doesn’t offer a built-in integration with Etsy. Both platforms are designed to work independently, so there isn’t a direct way to keep your inventory synced out of the box.

For merchants, that means you have two options:

Either you update stock manually between platforms, or use a third-party tool to connect them.

Manual updates work if you only sell a handful of items, but as soon as your catalog grows or sales pick up, it becomes error-prone and time-consuming.

This is why most sellers turn to apps or multichannel inventory software. These tools act as the bridge, ensuring that when an item sells on Shopify, the stock is automatically adjusted on Etsy and vice versa.

Methods to Sync Inventory Between Shopify and Etsy

Since Shopify and Etsy don’t connect directly, sellers usually rely on a few different methods to keep inventory aligned. The right approach depends on the number of products you manage and the amount of time you want to spend on updates.

Manual Updates

The most straightforward option is to log into both platforms and adjust stock manually whenever an order comes in. For example, if you sell a pair of earrings on Etsy, you immediately reduce the stock in Shopify.

While this method is free and simple, it doesn’t scale. The moment you get busier, it’s easy to miss an update and one missed adjustment can cause overselling. It also eats into your day, pulling you away from activities that actually grow the business.

CSV Imports and Exports

Both Shopify and Etsy allow you to export and import product CSV files. In practice, this means you can download your product list from Shopify, then upload it into Etsy to align inventory (or the other way around).

This approach is slightly faster than manual edits, especially for large catalogs, but it’s still not real-time. Stock is only accurate as of your last upload. If sales come in between exports, you risk mismatches. It’s a temporary solution at best.

Third-Party Inventory Sync Apps

For most sellers, the sustainable option is to use an app or inventory management tool that connects Shopify and Etsy directly. These tools update stock automatically across both platforms whenever a sale happens.

The benefits are clear:

• Real-time accuracy — no delays between orders and stock updates.
• Error reduction — prevents overselling or fewer chances of duplicate listings.
• Time savings — less admin work and no need for repeated CSV uploads.
• Scalability — works smoothly as your sales grow and channels expand.

Most apps come with a monthly fee, but for sellers handling more than a few orders per week, the time saved and customer trust protected usually outweigh the cost.

FAQs

1. Can Shopify sync inventory with Etsy directly?

No. Shopify doesn’t offer a native Etsy integration. You need third-party apps or tools like Sumtracker to sync inventory automatically.

2. What’s the risk of not syncing Shopify and Etsy inventory?

Without sync, overselling is common. You might sell items on one platform that are already out of stock on the other, leading to refunds and poor reviews.

3. Are CSV uploads a reliable way to sync inventory?

They work for small catalogs but aren’t real-time. Stock is only accurate at the time of upload, which makes overselling likely if orders come in between updates.

4. Do third-party inventory apps update stock instantly?

Most reliable apps, including Sumtracker, sync in real time. That means whenever a sale or return happens, both Shopify and Etsy update immediately.

5. Can bundles and product variations be synced between Shopify and Etsy?

Yes, but only with the right tool. Sumtracker, for example, handles bundles and component-based products so stock reduces correctly across all related items.
