Our philosophy is to build user friendly products at a price that allows justification even for occasional use.  We strive to develop our products with the features needed to provide value that allows you to succeed.

All products are tightly integrated with Excel in an environment that you are already comfortable.  You can also easily share your results with colleagues.  All products are sold as a permanent license, i.e. no recurring subscription fees.

Support and documentation are often the most critical factors in the purchase of software.  This is where you can be confident that your purchase is well supported and you have access to complete documentation, training materials and support.  One year of support is included with each purchase.  If you need support beyond one year, you can purchase it for a nominal fee, but you probably won't need it.

We also offer consulting services to build your simulation model or decision tree.  If you're not sure where to start, or want to outsource analysis, we can help.
