MerchantSpring

MerchantSpring is the marketplace analytics platform built for agencies and enterprise brands, unifying sales, profit, advertising, inventory, traffic, Buy Box, and customer performance across seller and vendor accounts on 120+ marketplaces including Amazon, Walmart, eBay, Shopify, and more. This connector puts all of it inside Claude. Ask questions in plain language and Claude pulls live, portfolio-wide metrics with period-on-period comparisons built in. Drill from the total portfolio down to a single store or SKU, covering sales trends, store and product-level profit and loss, advertising performance by channel, and 16 on-demand report types spanning inventory health, Buy Box performance, traffic and conversion, customer lifetime value, refunds, and repeat purchase. Ask things like "Compare sales across all client marketplaces this month vs last", "Which SKUs ran negative margins last quarter?", "How did advertising performance shift across channels week on week?", or "Show ordered vs shipped revenue for our Amazon Vendor accounts by month". Claude fetches the live numbers and does the analysis on the spot. For agencies, that means the whole client book in one conversation - filter any query by marketplace, country, or store tags, compare performance across every account you manage, and turn the answers straight into client-ready reporting. Seller and vendor accounts are both fully supported. Trusted by 35,000+ brands and agencies.
