Subtotal is quickly becoming the gold standard in merchant account linking—making it easy for shoppers to share their itemized retail purchases with brands by linking their retailer memberships to their accounts on brand websites.

Our platform enables brands and developers to bring first-party retail data into the digital experiences they build—powering loyalty, personalization, and new ways to engage customers in the retail channel.

Today, we’re excited to announce the launch of the Subtotal Shopify App — a powerful extension of our platform that helps Shopify merchants close the gap between DTC and retail.

For brands that sell both online and in stores, our app delivers the missing piece: the ability to recognize and engage retail customers just like you do digital ones.

The Missing Link Between DTC and Retail

The Subtotal Shopify App turns verified purchases from major retailers like Walmart, Target, and Sephora into actionable events inside the Shopify ecosystem.

That means when customers buy your product in-store you can automatically:

-️ Reward loyalty points just like you do for online shoppers -️ Trigger post-purchase SMS and email flows -️ Send personalized offers, cashback rewards, and tailored surveys

In short: your offline buyers can finally get the same great experience your online Shopify buyers already do.

This matters because as your brand scales, retail becomes a bigger part of the customer journey. And your ability to drive retention, engagement, and repeat purchases shouldn’t stop at the Shopify checkout.

The Subtotal Shopify App fixes this problem — so you can keep building relationships, no matter where your customers shop.

Example Use Cases

• Loyalty Reward: A customer picks up your product at Target? Great—they earn points just like they would online.
• Automated Messaging: Trigger personalized SMS or email flows after in-store purchases to say thanks, share tips, or promote a subscription.
• Cashback Offers: Drive repeat purchases by issuing cashback—whether the first order was on your site or in a retailer’s aisle.
• Reviews & Surveys: Request product reviews or quick surveys based on verified purchase behavior, not guesswork.
• Connected Customer Profiles: Link online and retail activity under a single view for smarter segmentation and more accurate LTV tracking.

How it Works

The Subtotal App is a plug-and-play extension fully integrated with our retail data platform. Add it to your Shopify store to get all the benefits of a custom Subtotal integration—without writing a single line of code.

We included the functionality you need—right out of the box:

✅ Customer Account Linking

Drop in configurable UI components that let shoppers link their retail accounts in just a few clicks.

🔄 Product Catalog Matching

Subtotal automatically maps retailer SKUs to your Shopify product catalog to detect relevant purchases—no manual setup required.

⚡ Verified Purchase Events

When a customer buys your product using a linked retailer account, Subtotal converts the purchase into a structured event and pushes it into Shopify.

These events integrate seamlessly with your loyalty programs and automations—and they’re also fully programmable, giving developers full control when needed.
