What We Shipped in Q1 2026

Q1 was a hugely productive quarter for Subtotal. We invested heavily across security and compliance, developer tooling, the Subtotal Dashboard, integrations, and the infrastructure powering it all. Here’s a quick look at some of what we shipped.

Security & Compliance

ISO 27001 Certification and GDPR Alignment

We achieved ISO 27001 certification and aligned our practices with GDPR requirements. ISO 27001 is the leading global standard for information security management systems, requiring an independent two-stage audit to verify that controls are correctly designed and operating effectively. GDPR alignment means the personal data of EU residents is handled lawfully, transparently, and in accordance with their rights.

Together, these milestones extend the foundation we built with SOC 2 Type II to meet global standards, giving brands, developers, and partners the confidence to build on Subtotal wherever they operate.

Dashboard

Connection Activity Log

The Connection Activity Log is now available in the Subtotal Dashboard. It surfaces the full history of states a connection has moved through, giving you a clear, chronological record of exactly what happened and when. For teams doing connection-level troubleshooting, handling a support ticket, or keeping tabs on their integration, this replaces guesswork with visibility.

Event Simulator

The Event Simulator is a new testing surface in the Dashboard that lets you exercise your integration end-to-end without real shoppers or real purchases. You can simulate account links, purchases, and unauthentication events and retrieve the resulting objects through the API exactly as you would in production. Simulated purchases include real products from your subscribed brands, so the payloads are realistic and useful.

Cross-Shopping Insights

You can now see aggregated cross-shopping data directly in the Dashboard, including the top products and brands that shoppers purchase alongside your SKUs. This is the first of many data-related features we plan to surface, and it's designed to turn the purchases flowing through Subtotal into something immediately actionable for your team.

Integrations

Klaviyo

We rebuilt the Klaviyo integration from the ground up. You can now build segments and flows based on retail purchase data and filter by retailer and UPC to power campaigns that weren't possible before, such as re-engaging shoppers who bought a particular SKU at Target in the last 30 days. The updated integration is live on the Klaviyo Marketplace.

Subtotal Connect

Subtotal Connect is now listed in the Shopify App Store, giving Shopify merchants a low-/no-code way to add retail account-linking entry points to their storefronts. You can see the docs here.

Smile.io

Smile.io joins our growing list of supported loyalty integrations. Brands running their rewards program on Smile.io can now connect it to Subtotal and drive earning actions from verified retail purchase data.

Loyalty Integration Configuration

We introduced configuration options across our loyalty integrations. You can now create custom earning actions with custom names and test those actions internally with limited visibility before rolling out to your full customer base. This gives you better control over how purchase data maps to your loyalty logic and a safer path to launch.

This is only a snapshot of what shipped in Q1. Alongside the features above, we rolled out a long list of smaller improvements across the platform, APIs, integrations, infrastructure, and developer tooling. We’ll be back with more updates as Q2 progresses. In the meantime, if you have questions about anything above or want to get started, book a demo with our sales team or sign up.
