What's a customer actually worth to you?
Not what they spent today. What they'll spend for as long as they stay. Most business owners have never worked this out. It takes about thirty seconds.
Now the harder question
The scenarios price the improvement. They do not tell you which of the three retention layers is weakest in your store, and that is what decides whether the improvement is a week of work or a quarter of it.
The Shopify Health Check does that part. 5 figures from your Shopify Analytics, each with instructions on where to find it, and 11 questions about what you have already built. It comes back with the weakest layer, what an improvement is plausibly worth against your own numbers, and an explicit list of what to leave alone. It never asks for access to your store.
The sales page runs the real report on an example store, so you can read the output before you pay for it. 30 day refund, no questions.
