Need help on UI with figma

I need help knowing how to give the clients the files.

I use Figma and PSD isn’t an option so I need help on how to do commissions. For example,

let’s say I finished a commission and I have to give the customer the file… How do I do that? Do i just give them the fig file?

Have you considered sending the fig file and a png as well? Then ask if they need anything fixed with the art after sending it.
