I wish I knew about them sooner!
I've been using ipaymy to pay my rent for more than a year now and I also used them for my income tax in 2020 and will do so again in 2021. I've never any issues and I've found their customer service very prompt and helpful (via facebook) on the 1 occasion I had a question for them. Over the past 12 months I've added over 120,000 points to my credit card loyalty program for less than 2% in fees! I wish I new about them sooner!
