Earn Money With Castle

The Castle Software Affiliate Program is an easy way for you to earn money by promoting our software. 

You can earn generous referral fees (between 25% and 50%) simply by linking to Castle Software from your web site, and having visitors click from your site through to our web site to download free trial software and purchase our software. 

You can put as much effort and resources into it as you wish; it could be a simple hyperlink, or it could be multiple pages of text and information along with custom builds of the software.

Castle Software handles all of the sales, customer service, and tracking of sales generated from your site.

Currently we will pay you up to 50% of any single sale of Castle Software applications that have been tracked and originated from your website.  

The good thing about this program is your referrals don't have to purchase anything right away. They might visit your website, then go to Castle Software and download the software and try it out for a month. You still will get the credit for the sale.

We use RegNow as our main affiliate processor. When you join, you get assigned an ID Code and are given some HTML code to link to a page on the Castle Software site. 

When one of your visitors sees your review or banner for Castle Software on your site, and decides to click on your link, they get directed to a page on the Castle Software site. 

At this page our site remembers that the visitor was referred by you. Your visitor then browses our web site and (possibly) downloads a trial version of one or more of our applications. 

If the visitor decides to purchase the software then our ordering page remembers that you referred them and passes it through the order process.  Our ordering page uses the RegNow affiliateCheck script to determine whether there is a RegNow cookie on the customers computer.

RegNow handles all reporting and payments. Their affiliate control panel allows you to specify how you want to be paid.
