I use Chargify for a SaaS company. I did a lot of research before choosing a vendor for this product because I wanted a solution that would scale and grow with us for years to come. After choosing Chargify, we couldn't be happier with our decision. Everyone we have worked with there has been top notch. Even the CEO, Lance, has been super responsive and helpful. He even helped us choose our payment gateway provider and we have been very pleased with them as well. Having this piece of the business figured out really made it easy to focus on other things and our launch was very smooth and everything has worked great.
