How to Combine Shopify Orders Automatically and Save on Shipping Costs

Managing multiple orders from the same customer can be a logistical and financial challenge. Shipping each order separately leads to higher fulfillment costs, increased packaging waste, and potential confusion in order tracking. By combining Shopify orders automatically, you can:

• Reduce shipping and packaging costs
• Streamline your fulfillment process
• Improve the customer experience
• Avoid duplicate shipments and tracking confusion

With the right tools and settings in place, automating this process can free up hours of manual work and boost your profit margins.

How Shopify Handles Orders by Default

By default, Shopify treats every order as a separate transaction—even if the same customer places multiple orders within a short time window. That means unless you manually intervene, each order is packed and shipped individually.

This is where third-party apps or custom automation become essential for merchants aiming to optimize shipping and fulfillment.

Benefits of Automatically Merging Shopify Orders

Here are the key advantages of using an automated system to merge orders:

1. Cost Savings: Combining multiple items into a single package lowers postage and handling costs.
2. Better Customer Experience: Customers receive one tracking number and one package, reducing confusion and increasing satisfaction.
3. Reduced Packaging Waste: Sending fewer boxes means using fewer materials, which is better for the environment.
4. Operational Efficiency: Fulfillment staff only need to handle and ship once per customer, instead of multiple times.

How to Combine Shopify Orders Automatically

When it comes to combining orders in Shopify, merchants typically have two primary options: manual merging or automated order consolidation. Our app, Voodux Extended Orders, takes the hassle out of this process by offering seamless automatic merging—saving you valuable time, reducing shipping costs, and improving customer satisfaction effortlessly.

1. Use our Shopify App Voodux Extended Orders

Voodux Extended Orders is a Shopify app designed to help you merge multiple orders from the same customer automatically. Here’s how it works:

• Automatically detects and merges orders from the same customer within a customizable time window (e.g., 24 hours).
• Preserves order details while generating a new “master” order for fulfillment.
• Automatically updates fulfillment status, ensuring that already shipped items are correctly reflected.

Setting up Voodux Extended Orders takes just a few minutes, and it can run in the background without manual intervention.

2. Create a Custom Automation with Shopify Flow (Shopify Plus)

If you’re on Shopify Plus, you can create a Shopify Flow that triggers when a new order is placed. Using conditions such as customer email and order time, you can trigger a merge or notify your team to do so manually. However, this requires more setup and might not be fully automatic.

Step-by-Step: Setting Up Voodux Extended Orders

To get started with automatically merging orders, follow these steps:

1. Install Voodux Extended Orders from the Shopify App Store.
2. Set the time window in which orders should be considered for merging (e.g., 12 or 24 hours).
3. Choose whether you want to merge orders manually or automatically.
4. Customize fulfillment rules to reflect already shipped items correctly.
5. Enable the automation and monitor your results via the app dashboard.

Things to Consider Before Merging Orders

Before enabling automatic merging, be aware of the following:

• Shipping Costs: Some carriers charge extra for heavier combined shipments. Run a test to see if combining truly saves money.
• Fulfillment Speed: Delaying shipments to wait for other orders may not suit customers who expect fast delivery.
• Inventory Management: Merged orders must accurately reflect stock and shipping status to avoid errors.

Real Example: How One Merchant Saved 30% on Shipping

A Shopify merchant running a beauty subscription store implemented automatic order merging using Voodux Extended Orders. Over one month, they saved over 30% on shipping costs and reduced packaging by 40%. Customers appreciated the consolidated shipments and clearer communication.

Best Practices for Managing Merged Orders

• Always notify customers when their orders are being combined to set expectations.
• Keep merged order notes visible for your fulfillment team to avoid confusion.
• Use automated rules to exclude certain order types (e.g., pre-orders or custom items).
• Regularly review merged order data to identify optimization opportunities.

Conclusion: Automate and Save with Confidence

Automatically combining Shopify orders is a smart way to cut costs, improve efficiency, and enhance your customers’ experience. Whether you choose a third-party app like Voodux Extended Orders or build your own solution with Shopify Flow, automation is key to scaling your store profitably.
