Consignment Inventory Management Software, powered by AI

Take your resale business to the next level with AI-driven pricing, lightning-fast listings, and effortless self-service.

Circular is consignment inventory management software built for consignment, resale, thrift, and buy-sell-trade. It automates the entire resale workflow. From intake and single-SKU cataloging to AI pricing, consignment split calculation, and live Seller notifications.

The product helps stores and brands scale without extra staff. Circular connects to the POS and e-commerce you already use (including Shopify) to track sales in real time and reconcile consignor splits automatically. The pricing engine gives you automatically the optimal price for the products you are adding to the system, helping you improve sell-through while protecting margin.

Unlike generic POS tools, Circular is resale-native. It supports intake bookings, item grading, bulk edits, photo and description helpers and smart rules. In addition, you get live analytics for sell-through rate, days on shelf, and revenue by brand, category, and sellers. You get a single source of truth for every item and consignor, automated messaging throughout the seller journey, and exports for accounting. In short: resale software that plugs into your stack, prices accurately, and keeps operations predictable. Explore all features.

We want to make resale accessible to everyone. That's why we're offering a free plan for businesses with less than $1,000 in monthly sales. View pricing details.
