How much can you pay to win a new customer? Most budgets never ask. They fund the channel and count the leads.
The 80/20 Marketer starts from a ceiling. Everything it costs to win a customer must come back from that customer's material margin within eighteen months.
In the book's worked example, a composite manufacturer, a new Fort customer, one like the few who carry the company, buys $90,000 in its first year and $180,000 in its second. Eighteen months of that buying, at a 44.5 percent material margin, is $80,100. Call it $80,000. A B customer buying B products for $10,000 a year, at 22 percent, has a ceiling of $3,300. Two sales visits and a box of samples will spend it.
Then work backward. Ten new Fort customers at a 25 percent win rate need forty qualified opportunities. Forty at 35 percent need 115 qualified conversations, about ten a month. So each qualified conversation is worth about $7,000. Nine trade shows had cost $520,000 and produced nine of them, about $57,800 each.
Here's the rule. Set the ceiling before you set the budget. Then hold every channel to what a conversation is worth.
The full method is in The 80/20 Marketer.
