Margin and payback for acquisition and retention belong in The Whole Machine. This chapter looks at the same customers through the bank account, where the difference is starker.

Two orders, two cash stories

Say a brand sells a $70 order whose goods cost $28, bought months ago. To win a new customer it spends $60 on ads, paid to the platform in the days before and around the order. To win a repeat order from an existing customer it sends an email and a text that cost it a dollar or two.

The new customer’s order uses $18 of cash. The repeat order leaves $40, enough to buy the goods for another order and a half. Shipping and fees make both columns worse, but the gap stays. A brand growing through new customers is spending cash to grow; one growing through repeat customers is being paid to grow.

A repeat order is the cheapest cash a brand can raise. Nobody has to approve it, and it comes with a customer.

Three ways retention shortens the cycle

• It funds the stock. The $40 above pays for the next purchase order.
• It makes demand predictable. Repeat buyers reorder on a rhythm, which lets you order smaller and more often (chapter 10). Reorder timing is covered in The Second Order.
• It fills the first tranche of every preorder in chapter 6.

What to measure

Split last quarter’s order cash by new and returning customers, with the marketing cash spent on each beside it. The query is in Appendix A.

Do this

• Build the two-column table above with your own numbers for last quarter. If the new-customer column is negative, growth needs cash in proportion to how fast you acquire, and the tool in chapter 2 understates it.
