Ask HN: What to consider for a SaaS product "moving" international

I'd like to expand the reach of my SaaS product internationally (or at least to English speaking countries around the world). Beyond extending my AdWords campaign to include Australia, New Zealand, England and etc, is there anything else I should be aware of? We currently use Stripe, not expecting any payment problems but I wasn't sure what else to be looking out for before doing this. Any thoughts, input or resources? Thanks!
