About Add-ins.com LLC

Add-ins.com LLC began business in 1994 as Macro Systems, specializing in custom macros for Microsoft® Excel®.  In 2007 we became Add-ins.com LLC to reflect our focus on add-in products for Microsoft Excel.

We are located at 144 Dewberry Drive, Hockessin, Delaware, USA 19707. Our direct phone number is 302-234-9857.  Our fax number is 302-234-9859. To contact us via e-mail, please use our contact form.  

Our products have been top rated by many of the independent software sites and magazines. Three of our products (Spreadsheet Assistant, Cell Color Assistant, and Sheet Navigator) took the top position for add-ins for Microsoft Excel in a PC Magazine's annual utilities issue.

In Microsoft Press's book on Office 2003, our Spreadsheet Assistant is the only add-in for Microsoft Excel (evaluation copy) distributed on the book's CD.

We view customer satisfaction and the quality of products to be our top priorities.  To that end, we offer a money back guarantee and are continuously improving our products.

We are continually developing our products and expect to release at least six new products each year.

The following is a screen shot of a code signing certificate we were issued (as Add-ins.com LLC) by Thawte.  Thawte only issues such certificates after they have authenticated a company by confirming that the company does in fact exist, that the company has authorized the certificate application, and that the person submitting the certificate application on behalf of the company was authorized to do so.  We sign all of our Excel products and our add-in installation EXEs to provide another level of security and trust, and to allow our users to maintain their Excel security set to high, the default setting in Excel.

If you would like to talk to us prior to a purchase or for help on a product you have purchased, call us at 302-234-9857, any day, from 8AM to 10PM, U.S. East Coast Time.
