NetSuite OneWorld is a scalable solution. I initially implemented it for a company with sixteen employees. By the time I completed the project, the company had about four hundred employees, meaning NetSuite OneWorld had to be scaled up. The company I work for now also doubled in size yearly for the past four years, and NetSuite OneWorld is still functioning as expected. Scaling up the solution affects the price. If you go over one hundred users, you're forced to go up to the next tier of environment, with a different cost. When you start small and go up to a million transactions in a year, the NetSuite OneWorld price also goes up. The scalability of NetSuite OneWorld is a ten out of ten.
