Stripe is expanding beyond the US so demand for an official whmcs module will only increase. They have now expanded to Canada and looks like they will be available in Europe soon.
There is a commercial module available, however, I don't know how well that commercial module works but they currently want $45 per year which is rather expensive for what it is imho. On a product like whmcs which only charges around $140 a year that is an additional 30%. Every little bit adds up when you have to pay licensing for every little thing like this.

The module will provide a seamless experience to customers - just like our other tokanisation modules. We have also spent time making sure that transitioning to this new module is straight forward. Provided the remote token IDs are stored in the WHMCS database beginning with the prefix "cus_", then switching to our module will just be a case of configuring it, deactivating the 3rd party module, and selecting the Official WHMCS Stripe module when prompted.
Migration instructions will be included in our documentation upon release.
