Laws that attach when you expand beyond the US
Selling software or services internationally is easier than ever from a logistics standpoint. The legal side is more complicated. When you have customers in another country, that country's laws may apply to your product and business practices — regardless of where your servers are or where your company is incorporated. The most significant obligations typically relate to data privacy, but they're not the only ones. Export controls, consumer protection laws, sector-specific regulations, and local tax obligations all potentially attach.
The practical starting point is understanding your data flows. Where do your customers reside? Where does their data go? Who can access it? For EU customers, GDPR is the primary concern — and it applies to your company even if you've never set foot in Europe. For customers in Brazil, Canada, Japan, South Korea, Singapore, and a growing number of other countries, national privacy laws with similar structures apply. Building a product that works across these frameworks from the beginning is significantly less painful than adapting it later.
