## Overview

Subtotal is an open commerce platform that helps brands, shoppers, and retailers build stronger relationships.

Shoppers use Subtotal to securely connect their retailer accounts—like Walmart, Amazon, and Sephora—to brand websites and apps, sharing first-party purchase data with the brands they engage with.

Subtotal turns those purchases into real-time events that power engagement, retention, and insights—enabling brands to reward customers, personalize experiences, and turn previously anonymous retail shoppers into known customers.

This documentation is a shared knowledge center for anyone building, integrating, or operating with Subtotal—including developers, marketers, operators, and partners.
