Do I need to provide an employment contract and salary proof as a one-man band Ecommerce company in Thailand?

As a one-person Ecommerce company in Thailand, you are not required to provide an employment contract to yourself, although others in similar situations have done so. Salary proof is generally optional unless specifically requested, but having documentation confirming your position and capability to work remotely is beneficial. Some users suggested using tools like ChatGPT to create a letter verifying your business structure and working status.
