Channel Mix Decision
A channel is not a place you sell — it is a separate business with its own cost base, and the platform dashboard is built never to show you that.
What it is
The portfolio decision behind the question every growing seller asks badly: where should we be selling. Costs each channel to one comparable figure — contribution per order after everything it drags behind it — then reads what each gives and takes beyond money: whose customer it is, who sets the price, how fast the rules can change under you. Ends in a verdict per channel, a concentration threshold that names a dependency, and an execution plan carrying the migration, parity and inventory work. For founders and ecommerce managers running three channels on the belief that all three earn their place.
What you receive
an evidence-based answer to where you should be selling — every channel costed to contribution per order after commission, fulfilment, the advertising required to stay visible, returns and labour; the read of what each gives and takes in customer ownership, price control, discoverability and rule exposure; the concentration threshold that names a dependency; an add, invest, hold, harvest or exit verdict per channel under a sequencing rule forbidding two launches at once; and the execution plan carrying the migration, parity position, inventory allocation and quarterly re-cost
