Case Study: Off-Season Purchases
We've learned that "Beans: The Internet's Only Variety Store" is heavily skewed to the November/December timeframe.
I've learned across nearly twenty years of consulting project that it's not healthy for a business to skew so heavily to Christmas. You want to offer products that customers purchase all-year. If there's a reason that subscription-centric brands are coveted by investors, there's the opposite reason that Nov/Dec businesses aren't coveted.
When I see a skewed business, I run a regression model to test the dollar contribution of Oct/Nov/Dec orders vs. orders generated during the rest of the year. For twelve-month buyers, spanning four years of purchase history and one year of "prediction", here's the simple regression equation.
- 1.257 + 0.079*($ Spent in Oct/Nov/Dec) + 0.095*($ Spent Jan-Sep).

Case Study: Simple Forecasts
- 9.4% from last year's Apparel Tops AND Other Category buyers.
- 6.4% from last year's Apparel Tops only customers.
- 4.7% from last year's Other Category buyers.
- 79.5% from New/Reactivated buyers this year.
- Category Yes, Other Yes = $5.98 in the next year.
- Category Yes, Other No = $4.58 in the next year.
- Category No, Other Yes = $1.44 in the next year.

Case Study: When The Crabby Merchant Is Right ... And Horribly Wrong At The Same Time
In the email dialogue shared yesterday, the Chief Merchandising Officer suggested that her customers had long repurchase cycles, therefore, it's not fair to measure future value across only twelve months.
For "Beans: The Internet's Only Variety Store", she is both correct and horribly wrong at the same time.
Her customers have long repurchase cycles. I use my Life Table Methodology to measure repurchase activity/cycles. Here is what the data looks like.
The green table shows incremental repurchase probabilities by month, as well as cumulative repurchase probabilities by month, for 1x buyers, 2x buyers, 3x buyers, and 4x buyers. The graph next to the green table maps out incremental repurchase probabilities for first time (1x) buyers. Look at that stupid-high spike at month = 12. What do you think that is?
- It is customers coming back and repurchasing at high rates exactly one year following a first purchase.
- New customers spend maybe $11 in year one, $7 in year two, and $4 in year three. In total, that's $22 of future demand ... it's nothing.

Case Study: An Email Correspondence
Maybe the most important finding in the past week is that "virtually nobody" is repurchasing when acquired by "Beans: The Internet's Only Variety Store!", regardless of merchandise category. Discovering the fact is one thing. Communicating the fact is quite another thing. And sometimes, the communication results in a reshaping of the message I convey.
This is why I send "tidbits" in my projects ... the back-and-forth interaction is useful and helps shape the outcome of the project.

Does Sloane have a point? Sort of. But the point doesn't change the fact that your customers have minimal future value.
If I measure repurchase activity over three years instead of one year, repurchase rates improve from maybe 18% to 33%. In that manner, Sloane is right.
Let's look at annual spend for customers acquired four years ago. Year1 = $10.68 in sales. Year2 = $6.92 in sales. Year3 = $4.08 in sales.
The story doesn't change ... the customers you acquire have virtually no future value when converting sales to profit. You have to generate a lot of profit on a first order to stay in business.

His experience is limited - those companies are too big to matter. $20,000? Highway robbery. I'll get you better answers from AI for minimal cost. Let's focus on the future, not an antiquated business model where some dweeb is paid a premium for something software can easily generate for free.
Ask Goober if customers have a longer repurchase cycle? I think he's looking at the issue the wrong way. Marketers are marketers for a reason, they're simpletons who are too narrow-minded to have the world-view you and I have to have to run a business.

He was part of the Management Teams at both Eddie Bauer and Nordstrom back in the day. We're paying him $20,000 for his work.
Also, we're breaking too many eggs. Sales are down 20% since your arrival. We can't survive if we go below $16 million in annual sales.

First of all, who is this propeller-head you are working with? You can tell this Goober never worked for a real business, he's just out there wandering aimlessly in the Land of the Theoretical. How much are you paying for his "insights"?
Anybody with half a brain knows you don't measure lifetime value within twelve months. It's called Lifetime Value for a reason. You measure the Lifetime. That's what I'm working toward. And if we have to break a couple of eggs along the way, so be it.

Case Study: Which Categories Bring In Valuable Customers?
I ran an analysis, measuring how much future value (demand/sales over the next twelve months) a customer will generate after being acquired within each merchandise category. If a category does a great job of bringing in new customers and those customers don't spend money in the future, well, we've got a problem.
Here's a summary table of what I learned.
Apparel Tops is a high-volume category, and fortunately it is a top-three category in terms of future value (NY Value).
Notice that most categories generate customers that buy from nearly two categories in the next year if the customer repurchases.
However ...
However, there is a problem in this table.
When a customer is acquired, regardless of category, the customer spends very little in the next year. Seasonal is worst ($6.40) ... Outside is best ($11.33).
In other words, there is very little customer loyalty associated with this brand. Newly acquired customers have a low chance of buying in the first year with the brand (between 14% and 18%), and if they buy the don't spend much ($46.00 to $63.00).
This is one of those moments when the Consultant realizes s/he is about to anger people. Yes, you can run a profitable business with a customer base that simply doesn't spend much, but it means everything regarding the p&l is dependent upon generating profit off of a first purchase.
Tomorrow, I'll share what the conversation looked like regarding exceptionally low future value metrics.
