How does your msp do new pc deployments?

How does your MSP handle setting up PCs for a customer? Do you do the entire setup on site at your location (connect to VPN to domain join,etc), then drop off, sign them in, and do the final touches on site with the customer?

Do you do the basic OOBE setup on site, and the rest (domain join, printer add, share maps, etc.) on site at the customer?

Or is there another way you're handling new pc deployments?

TIA
