If you are a former WBS Chart Pro* user looking for a direct upgrade or simply do not have a need for Network Charts or Gantt Charts then this product is for you.
*WBS Chart Pro was our flagship product for over 20 years. In 2014, WBS Chart Pro was combined with our other former product, PERT Chart EXPERT, to produce the all new WBS Schedule Pro software. Subsequently, the WBS Chart Pro software was retired and is no longer available.
WBS Chart Pro users – The WBS Chart Pro features you have become accustomed to plus much more are now a part of WBS Schedule Pro!

Account Details
When you create an account we will use the information in the current order to generate an account number and setup your account. Upon the completion of your order you will receive an email containing your account password and instructions for accessing the Customer Portal.
Benefits
Some of the benefits of having an account are:
Note: For security purposes, your credit card information is not stored with your account information. In fact, we never see your credit card data or have access to it. As is common in the industry, your credit card information is passed through a secure gateway directly to the credit card processor when you place an order on our site. Your credit card data is always safe when you shop with us!
To transfer a license, start a registered version of WBS Schedule Pro and select File-Unregister. This puts the license back so it can be registered elsewhere.
In the event that the software is no longer available due to a hard drive failure, re-format, or re-image, contact us with the User Name or Computer Name. We will then reset that license here so you can register again.
Remember: Uninstalling the software does not Unregister the software!
