Inventory Software for Resellers - Management Solution

Reselling demands real-time visibility across every SKU, location, and channel — and off-the-shelf tools rarely keep up. Keel's custom inventory management software is built around how your resale operation actually works: multi-channel stock sync, automated reorders, lot tracking, and deep integrations with platforms like Amazon and Shopify, all in one system you truly own.

The Keel Difference

Why Choose Keel for Inventory Management?

Built by operators who lived the pain of inflexible software, Keel gives resellers the control and agility legacy tools never could.

Built by Operators

Founded by executives who scaled a pharmacy to $130m revenue using custom-built operations software — they understand what resellers actually need.

Total Ownership

You own your data, your workflows, and your system — iterate and evolve it freely without depending on a vendor's roadmap.

Weeks, Not Months

Go from business requirements to a live, production-ready inventory system in weeks, not the months legacy ERP implementations demand.

Seamless Integrations

Connect to Amazon, Shopify, 3PLs, and financial tools via API — keeping stock, orders, and returns synchronised across every channel you sell on.

Meet the Team Behind Keel

Operators who built world-class systems and then made that power available to everyone.

Keel was founded in 2021 by three former executives — CEO, CTO, and CPO — from Echo, Europe's fastest-growing online pharmacy, later acquired by Pharmacy2U. At Echo, they built and ran custom operations software that shipped 50,000 medicines to 600,000 customers daily and grew the business to $130m in annual revenue. They saw first-hand how off-the-shelf tools couldn't scale or flex to meet real operational demands, so they built the solution they wished had existed. Headquartered in Altrincham, Cheshire, Keel has since raised $6m in seed funding from leading European investors Earlybird and LocalGlobe, and is on a mission to empower operators everywhere — from resellers to regulated industries — with flexible, powerful software they truly own.
