I could not successfully sign up and the information on the site is very limited. What exactly does your service do? It implies all tax compliance, but I find that hard to believe. Perhaps you can confirm you comply with all the payroll requirements of the jurisdictions you operate in?

A US company that employs an individual resident in Canada is required to: - Keep W-8 on file - Register for a Canadian tax ID - Keep a "shadow" payroll system in Canada, and report monthly the payroll to the Canada Revenue Agency - Deduct Canada Pension Plan, Employment Insurance, and income taxes, and remit to the Crown (1) - Issue a T4 slip at the end of the Year (W-2 equivalent)

The above process is very different for a US company that employs an individual resident in the UK or France.

There are other factors to consider: residency status, hypothetical tax and equalization payments, and treaty relief comes to mind. I ask because, what we would call "Global Mobility Services" consisting of cross-border taxation of employees, is pretty much done in Excel because of the thousands of permutations possible with the above factors and 190 odd countries of the world.
