The JCS software runs on all current Windows operating systems including Windows 10. There is also a .Net version that uses SQL databases.

We are custom programmers and can make changes to the software promptly as needed. There are hundreds of options that can turn functions on or off. The software is for single or multi-stores, and includes the many features covered elsewhere on the site.

When you decide it is time to computerize your store, or to make a change to the procedures you are currently using, you are not forced to buy all of the modules. You can start small and grow. We have a section on the website that goes into further details on this approach.

We consider our customers to be like family. Customer support is extremely important to us, and if you have questions or problems you will speak to a person either immediately or within a few minutes. This is our promise to you.

To provide our customers with state of the art
that helps their business grow.

Here are some of the areas we can help you with:

Analysis Reports

We provide the best analysis reports available to allow you to optimize your inventory. You can spend $20,000 for an inventory program from one company that can't do as much as ours can.

Internet Marketing

We can show you how to use the Internet to market your jewelry. This will be extremely important in the future. We think the future is now.

Creating Appraisals

Create professional appraisals with a color photo of the jewelry on the appraisal.

Slide Shows

Create slide shows that a customer can look at while browsing in your store.

Credit Card Processing

Use the JCS software to do credit card processing for you.
