This document, the "Data Entry and Troubleshooting Guide" for the Shipper Tool, is the second of two guides available to help your company participate fully in the SmartWay Transport Partnership as a Shipper Partner. The Shipper Tool "Quick Start Guide" is a basic walk-through of the process of identifying, gathering, preparing, and submitting your data by using the SmartWay Shipper Partner Tool, and includes several worksheets referenced in this guide. (From this point on, this guide will refer to the SmartWay Shipper Partner Tool as the "Shipper Tool" or simply, the "Tool," for brevity.) The Quick Start Guide may be all you need to successfully complete the Shipper Tool. However, the Data Entry and Troubleshooting Guide is intended for situations in which you have already read the Quick Start Guide and prepared your data for entry, but need more information on how to complete your data submission than is provided in the Quick Start Guide.
