Evaluate an e-commerce order as a small economic system: customer acquisition brings the buyer in, average order value captures the basket, and product plus fulfillment costs determine what remains. The goal is not simply to raise revenue, but to improve the amount left after serving and acquiring the customer. OT expanded from a single tie into pocket squares, shirts, and polos that customers could buy together. The guest says its average order value rose from about $30 initially to more than $150, sometimes around $200. A larger basket can support more acquisition spending, but only when the added merchandise does not introduce offsetting costs. The framework therefore links merchandising, acquisition, and operations in one recurring calculation rather than judging each area separately.

Core principles
- 01Revenue is not profit
- 02Acquisition capacity rises when each order carries more value
- 03Product expansion should strengthen the basket rather than add random complexity
- 04Fulfillment and product costs belong in the same decision
How to run it
- 1
Measure acquisition cost
Calculate how much marketing spend is required to acquire a customer for the relevant period or channel.
Watch out Do not treat revenue from an acquired customer as profit.
- 2
Measure the basket
Calculate average order value and identify which products are commonly purchased together.
Pro tip Look for combinations that solve one customer occasion or need.
- 3
Subtract delivery costs
Include product, fulfillment, and other order-level costs to determine what remains after the sale.
Watch out Apparel additions may also increase returns, which must be considered.
- 4
Design complementary expansion
Add products that naturally increase the customer's basket instead of accumulating unrelated inventory.
Pro tip OT paired ties with pocket squares, shirts, and polos.
Watch out More SKUs are not automatically better unit economics.
- 5
Reinvest within the equation
Use the improved contribution per order to determine whether the business can responsibly spend more to acquire customers.
Watch out Recalculate as channel costs, returns, and fulfillment expenses change.
In the wild
OT began with an average order value of about $30 for a single tie. It introduced pocket squares and later apparel such as shirts and polos that could be purchased together. The guest reports that average order value eventually rose above $150 and sometimes reached about $200.
→ The larger basket increased the amount OT could potentially spend to acquire a customer, subject to its other costs.
Common mistakes
Optimizing revenue alone
A larger order can still be unattractive if product, return, or fulfillment costs consume the increase.
Adding unrelated inventory
Random assortment growth can create complexity without increasing the natural customer basket.
Is it for you?
Best for
It is best for stores that can measure acquisition and fulfillment costs and offer genuinely complementary products.
Not ideal for
It is not ideal when product additions raise returns, inventory burden, or fulfillment costs more than they raise order value.
From the transcript
“what the average order value is the cost of fulfillment you know customer acquisition cost”
“what you're left is you know your your profit”
