Hi,
I'm not familiar with Wikipedia guidelines, but looking a bit at the Talk page, there are some requirements to be listed there.
The software needs to have its own page:
en.wikipedia.org/wiki/Talk:Comparison_of...fiability_of_entries
And be "notable" enough, with 3rd party sources, etc.
And as far as I know, there are no Wikipedia page for HikaShop. So you would have to start with that.
We would be happy to provide information if necessary.
Regarding the payment gateways, HikaShop support most of the ones listed there and a lot of others not listed.
