The Closed P&L Problem | TikTok Operator Pod | Special Guest: Amy Leffingwell, Founder @ UpMkt Digital

Most brands are measuring TikTok Shop, Meta, and Shopify like three separate businesses. Then they wonder why the math never works.

That's the closed P&L problem: channels measured as monoliths in an era where the consumer is anything but.

In part one of a multi-part series with Amy Leffingwell, founder of Up Market Digital and one of the few people in performance marketing who thinks like a CFO, we get into why contribution margin has replaced ROAS as the number that actually matters, why "profit now, profit soon, profit later" is the only useful way to bucket a brand, and why the CAC-to-LTV math has to be run across channels before a single dollar goes into a new one.

We cover:
 – Why in-platform ROAS is a lagging, context-free number
 – How to price TikTok Shop against Shopify and Amazon without cannibalizing LTV
 – The unit economics most operators can't answer at the SKU level
 – Why some months should be planned for negative contribution margin on purpose
 – How brands kill TikTok Shop by underwriting it against its own P&L instead of the full picture

Amy runs the numbers. Jake runs the shop. The channels only work together when someone is doing both.
