Best ways to track offline marketing sales for local businesses
I would like to start a digital affiliate agency in a little town, and basically advertise on facebook for companies, and get sales (mostly selling services such as massages, courses, event management services, etc.) for them. Lots of them aren't online and don't necessarily want to start a website or facebook page.
I'm sure I can actually find customers for them but not sure how to track those sales... I've thought maybe about a voucher system, where the client actually pays me, and then I go and pay the supplier. But i'm not sure this is the best way to go about it.
Could anyone with experience guide me, or give pointers?
Best regards
