Both Wintix and Webtix work with Authorize.net (it’s owned by Visa).
Stripe is also a popular option.
NMI is also an option, though it only works with Webtix.
Since you are evaluating these systems, we recommend checking a few things:
- How reliable have the services been? In our experience, both have been very reliable.
- How helpful is the support? Stripe personnel are not available by phone – only by email and chat. Authorize.net has real humans (mainly in Utah) that are pretty good.
- How expensive is the service? Stripe charges 2.9% + $.30 per transaction. Authorize.net charges a gateway fee plus the interbank charges. Every transaction can have a different rate, depending on the risk. This makes figuring out charges very difficult.
