# BoslogShip BoslogShip is a free US shipping overpay checker and shipping label platform for approved business shippers. The public checker helps ecommerce sellers, small businesses, Shopify merchants, and warehouse teams test whether a package may have been overpaid by comparing ZIP codes, package dimensions, weight, and optional paid amount against available BoslogShip default client rates. Account workflows then support label purchase through portal, Shopify, CSV or Excel batch upload, and Open API integrations. ## Core Capabilities - Public shipping overpay checker that calculates rates only and cannot create labels - Public affiliate program page for referral partners, with account application routed through authenticated approval workflows - Multi-carrier rate comparison for enabled client services - Shipping label creation through portal, Shopify, CSV or Excel batch upload, and Open API workflows - Tracking records, label files, wallet charges, retries, cancellations, and exports - US-focused parcel workflows for ecommerce, warehouses, 3PL teams, and connected systems ## Safety Boundary - The public checker accepts package and optional paid-price inputs for rate calculation. - It does not accept label purchase fields, provider account selectors, payment fields, or internal carrier credentials. - Shipping labels can only be purchased after logging in to an approved BoslogShip account. ## Important Public Pages - [Compare carrier rates, buy labels, and keep every shipping record in one place](https://boslogship.com/en): BoslogShip is a free US shipping label platform for ecommerce and warehouse teams.
