I'm planning on offering some customer reactivation campaigns to hobby shops and jewelers but a potential point of concern is in the tracking of revenues and profits I generate for the businesses. I'm not sure how to track walk in business other than offering discount codes to the reactivated customers and then asking the business owner how much revenues were generated and what the bottom line profit for the campaign was.
I want to be trusting but the incentive for the owner sure is stacked the other way if we do a rev or profit share agreement, which is my preference.
Is there a better way to account for campaign performance when you're not local to the target business? And Is this even something one should spend their time considering, or is it fine to rely on what the business owner claims you did for him?
