Online payment processing - best one for resellers?

Can anyone recommend a company to use, for setting up reseller accounts?

There seems loads out there.

Thanks

Authorizenet is used by so many carts …
it’s a really good system to offer I think.

Who wants to sell a customer and then lose
the sale when the cart they use is not compatible?

That is where a system liek Authoriznet is great.
