I have been using CharityAdvantage for about five years. I never had an issue with the donations system and it connects to PayPal which is rock solid. I couldn't see how there would be any issues with that unless one didn't follow the simple instructions. CharityAdvantage support is fast and thorough but I don't use it much - it is a pretty simple system to use. My site has never been down. People just exaggerate. A website would never be online 80% of the time. How could a website be down that much? I have referred many customers to CharityAdvantage and don't know of any complaints about down time. I was referring someone recently and they asked me to check about up time and the answer was the same as I got five years ago: 99.99% up time. Any major host will have that.
Thank you for the positive review. Our donation system always works and you are correct that we maintain an industry standard 99.9% up time rate. The user that stated otherwise was either incorrect or perhaps had an issue with their domain name which is outside of our control and support.
