Please click the download link on your screen and install the *Web Connector* on your local computer. You must install *Web Connector* on the computer that is running QuickBooks. Download the [QuickBooks Web Connector](https://quickbooks.intuit.com/learn-support/en-us/install-new-products/set-up-quickbooks-web-connector/00/185852) installer to a location on your computer and run the installer by double clicking on it.   ## The QWC File This is a settings file (with a ”.qwc” extension) that will automatically configure Web Connector when opened. Web Connector already knows what to do with this file. All you need to do is obtain the .qwc file from ProductCart (Step Three of the Setup Wizard) and open it on the computer running QuickBooks. From Step Three, to open the QWC file: - In your browser, click *Activate Web Connector* on Step Three of the Setup Wizard (*QB\_Setup3.asp*) - You will be prompted to save or open a special configuration file. Click *Open* and follow the prompts. The *Authorize New Web Service* window *may take several seconds to appear*. Wait until you see it appear on your desktop, then click *OK*. - Return to the Setup Wizard - [Managing Your Products](https://productcart-kb.nsource.com/kb/managing-your-products?hsLang=en) - [Managing Orders](https://productcart-kb.nsource.com/kb/managing-orders?hsLang=en) - [Managing Customers](https://productcart-kb.nsource.com/kb/managing-customers?hsLang=en) - [Getting Started](https://productcart-kb.nsource.com/kb/getting-started?hsLang=en) - [Apparel Add-On](https://productcart-kb.nsource.com/kb/apparel-add-on?hsLang=en) - [Upgrading ProductCart](https://productcart-kb.nsource.com/kb/upgrading-productcart?hsLang=en) - [Change Logs](https://productcart-kb.nsource.com/kb/change-logs?hsLang=en) - [Store Settings](https://productcart-kb.nsource.com/kb/store-settings?hsLang=en) - [Security](https://productcart-kb.nsource.com/kb/security?hsLang=en) - [Shipping Options](https://productcart-kb.nsource.com/kb/shipping-options?hsLang=en) - [Payment Options](https://productcart-kb.nsource.com/kb/payment-options?hsLang=en) - [Tax Options](https://productcart-kb.nsource.com/kb/tax-options?hsLang=en) - [Advanced Technical Articles](https://productcart-kb.nsource.com/kb/advanced-technical-articles?hsLang=en) - [Pages](https://productcart-kb.nsource.com/kb/pages?hsLang=en) - [What's New In ProductCart](https://productcart-kb.nsource.com/kb/whats-new-in-productcart?hsLang=en) - [Marketing](https://productcart-kb.nsource.com/kb/marketing?hsLang=en) - [How To's](https://productcart-kb.nsource.com/kb/how-tos?hsLang=en) - [Google Analytics](https://productcart-kb.nsource.com/kb/google-analytics?hsLang=en) - [QuickBooks Sync](https://productcart-kb.nsource.com/kb/quickbooks-sync?hsLang=en) - [Default](https://productcart-kb.nsource.com/kb/default?hsLang=en) - [Configurator](https://productcart-kb.nsource.com/kb/configurator?hsLang=en) - [SEO](https://productcart-kb.nsource.com/kb/seo?hsLang=en) - [Mobile Commerce](https://productcart-kb.nsource.com/kb/mobile-commerce?hsLang=en) - [Troubleshooting](https://productcart-kb.nsource.com/kb/troubleshooting?hsLang=en) - [Customizing Your ProductCart Store](https://productcart-kb.nsource.com/kb/customizing-your-productcart-store?hsLang=en) - [ProductCart Apps](https://productcart-kb.nsource.com/kb/productcart-apps?hsLang=en) - [Hidden Topic](https://productcart-kb.nsource.com/kb/hidden-topic?hsLang=en) - [Reports and Exports](https://productcart-kb.nsource.com/kb/reports-and-exports?hsLang=en) [![ProductCart Logo](https://productcart-kb.nsource.com/hs-fs/hubfs/pc_logo.png?width=200&height=93&name=pc_logo.png "ProductCart Logo")](https://netsourceinc.com) NetSource Commerce, Inc. **|** Headquarters - 3700 South Pine Avenue, Ocala, FL 34471 **|** Tel [(800) 709-3240](tel:+8007093240) **|** Fax (352) 401-0353 [mailto:help@productcart.com](mailto:help@productcart.com) Copyright © 2026, NetSource
