About the project

Simple tools for everyday online selling

SellSmart Tools UK is a free toolkit for UK online sellers who want useful answers without complicated software.

What SellSmart Tools UK does

The site helps with common selling tasks such as estimating profit, building and checking listing titles, and getting a general parcel size guide. It is designed for eBay sellers, beginner dropshippers, marketplace sellers, and small businesses.

Every tool works directly in the browser. There is no account to create, no software to install, and no server-side processing for the information entered into the tools.

Estimates, not official advice

SellSmart Tools UK is independent and is not an official eBay or courier service. Always check current marketplace fees, policies, parcel rules, and business requirements before making a decision.
