Give your staff or clients a QR code. They answer one simple request with a photo, no app and no login. It lands in your Buffer, captioned and ready for an empty slot.
Print the poster for the staff room, or send the link to a client. Shoebox writes the requests for you.
Fifteen seconds on their own phone. Nobody needs a Buffer seat, an app or a password.
Review each photo, tweak the suggested caption, and send it to Buffer. Nothing publishes on its own.
