Jun 16, 17 - Make money by referring us

Have you used our ProCalc Jetting Calculators and know someone who might benefit from using it? Wanna make a little bit of money?

We are opening up our dealer program to anyone who is interested!

Here's how it works:

  1. We will set you up with a dealer id and custom link. That link will provide your referrals with a free 15 day trial of our ProCalc Jetting Calculators.
  2. You send that link to anyone you think could benefit from using our site. They can try out ProCalc for 2 weeks with no obligation to buy.
  3. If they do end up purchasing a subscription, we'll send you some money!

Terms and conditions apply. Contact us for further details.
