Who This Helps
This is for founders who see a key metric drop and need to know why before the week is out. It’s part of the Founder Finance Basics Mission Pack, which helps you make calm decisions with clear numbers.
Mini Case
Ben’s weekly revenue per customer dropped from $45 to $38. His gut said ‘seasonality,’ but a quick 30-minute session showed his new customer acquisition cost (CAC) had spiked to $120. The real problem? A recent ad test was attracting low-value sign-ups. He paused the test, and the next week’s revenue per customer climbed back to $42. A little focus saved a month of drift.
Do This Now (5 Steps)
- Block 45 minutes on your calendar. Close other tabs. This is your investigation time.
- Grab your last two reporting periods for the KPI that dropped. Write down the old number and the new number.
- Check the three upstream drivers. For a revenue drop, look at: Customer Count, Average Order Value, and Purchase Frequency. Which one moved?
- Trace that driver back one more step. If customer count fell, where did they stop coming from? Check your top two channels.
- Name the single most likely root cause. Write it in one sentence. For example: “Facebook ad leads are costing 40% more but converting 20% less.”
Avoid These Traps
- Don’t blame ‘everything’ at once. One primary cause is usually hiding behind the noise.
- Don’t skip comparing periods. You need the before-and-after to spot the change.
- Don’t get lost in perfect data. Use the numbers you have now; you can refine later.
- Don’t ignore your pricing page. A confusing change there can silently sink conversion.
- Don’t forget to check a major platform update. Did an app store or ad platform change its rules last month?
- Don’t assume it’s permanent. Often it’s a temporary campaign or a bug.
- Don’t diagnose alone. Run your one-sentence cause by a teammate for a sanity check.
- Don’t move to solution mode until you agree on the cause. Otherwise, you’re fixing the wrong thing.
Your Win by Friday
By Friday, you’ll have a clear, one-sentence diagnosis for that nagging KPI drop. You’ll know if it’s a channel issue, a pricing hiccup, or a seasonal blip. You’ll move from worried speculation to a focused action plan. And you’ll have a repeatable 5-step method for the next time a number looks funny. Time to play detective.
