How renewals quietly double your demand
New customers stay level at a fixed pace. Renewals grow on top of them, every cycle. Here is the maths, with a chart you can draw on a napkin.
Say you sign 20 new subscribers a week and 90% of them reorder every four weeks. In week one you ship 20 first orders. In week five you ship 20 first orders and 18 renewals. In week nine, 20 + 18 + 16. By week 20 you are shipping more than twice what you shipped in week one, with exactly the same marketing.
Why the spreadsheet misses it
A spreadsheet looks at last month's sales and projects them forward. But last month's sales already include some renewals and not others, and the mix changes every week. The only way to get it right is to model the three streams separately:
- One time orders: flat, driven by traffic.
- First orders from new subscribers: flat, driven by your new customer pace.
- Renewals: compounding: every cohort comes back at the reorder rate, every cycle.
What if is the real feature
Because the streams are separate, you can ask Hylla what happens if the new customer pace doubles. The answer is rarely "order twice as much", it is usually "order a bit more now, and a lot more in eight weeks". That gap is where cash gets tied up or shelves go empty, depending on which way you guess.
We built the what if controls so you do not have to guess.
