A common question we get from customers is whether ERPNext or any other Frappe app scales to thousands and millions of transactions or users. Although there is no easy way to answer the question, people are eventually surprised to find out how scalable our apps are designed to be by default. We have customers using our apps to run a payroll for 30,000+ employees, India's largest stock broking platforms with millions of transactions per day, and many such examples. 

When it comes to Frappe Cloud hosting, we understand that as your business grows, so will your computing needs. Frappe Cloud is amazingly easy to scale up or down with a few clicks. However, scaling up and paying more is rarely the right answer for large enterprises, so we also offer consulting to help them with non-battle-tested scalability challenges.
