If you're selling through a channel you don't fully control, you're already operating with constraints most marketing tools weren't built around. Geo-restricted and regulated reselling adds another layer: the rules about where you can sell, what you can say, and who you can say it to are not set by you, and they are not uniform across markets.

You ran the campaign. The clicks came in. The phone rang. And then the sale happened somewhere you can't see: on a dealer's floor, through a distributor's order system, or inside a call center that doesn't share its data with you.
