EP385: Stop guessing your next Amazon FBA purchase order and protect your cash flow from expensive markdowns
Take the total units sold in the last twenty-eight days and divide by twenty-eight. This gives you your daily sales velocity for each SKU.
Key Takeaways
- Calculate daily sales velocity for each SKU.
- Avoid guessing inventory based on total sales.
- Recognize the impact of bad data on decision-making.
- Implement a clear framework for purchase orders.
Hook
You are still guessing your next Amazon FBA purchase order because you are looking at revenue instead of units. I'll close with The Voltage 3, today's challenge. the units per day number that says reorder now, the SKU already heading into a markdown, and the cash you keep by waiting on the next inbound.
Insight
But before I unlock today's Voltage 3 insights, look at the math. A product selling eighty-four units over twenty-eight days moves three units a day. That is velocity. Now take sixty units in stock. Divide by three. You have twenty days of inventory. If your supplier lead time is thirty days, you are already dead. You will stock out. Or worse, you order too late and pay expedited freight. That is where cash flow dies. I was reading a Practical Ecommerce piece earlier and it made this clear. Revenue is vanity. Velocity is sanity. Two products can make ten thousand dollars a month. One sells twenty units at fifty dollars each. The other sells four hundred units at twenty-five dollars each. Same revenue. Totally different risk. The second one needs reordering twice as often. If you ignore that, you bleed. Across my thirty brands, we watch velocity first. We do not trust the revenue line alone. It lies. It hides the real cash flow trap. Most sellers wait until inventory days drop below lead time. Then they panic. Then they overorder. Then they get stuck with dead stock. That cycle kills margin. That cycle kills freedom. I homeschool my daughters. I am home every day. I cannot afford to have my business steal that time with emergency sourcing calls. Velocity tells you the truth early. It tells you when to act. It tells you when to stop. That is how you protect cash flow. That is how you sleep at night. You stop guessing. You start knowing.
Example
Let's talk about David. He's one of our operators. He was doing thirty thousand dollars a month. Solid. But he was guessing on inventory. He looked at total sales. Saw a dip. Assumed the trend was over. Cut his next order by half. Demand rebounded. He was out of stock for three weeks. Lost ranking. Lost customers. We rebuilt his velocity model. He started tracking seven-day, twenty-eight-day, and ninety-day windows. He saw the acceleration early. Ordered on time. Now he is at a new high of one million, nine hundred thirty thousand dollars a month in June. Six SKUs became one hundred plus. But it started with one number. Units per day. Not revenue. Not feelings. Not hope. He stopped guessing. He started calculating. And that changed everything. I have seen this pattern across our portfolio. Operators who track velocity win. Operators who guess lose. It is not about being smarter. It is about being systematic. It is about respecting the data. It is about knowing that a slow week does not mean a dead product. It might mean a seasonal lull. It might mean a competitor issue. It might mean your ad spend dropped. But if you do not look at velocity, you will never know. And that ignorance costs you real money. Real cash. Real margin. David proved that. He stopped guessing. He protected his cash flow. And he scaled to a level most operators only dream about. That is the power of velocity. That is the power of knowing.
The Voltage 3
Here is The Voltage 3. Number one: Calculate your daily sales velocity for every active SKU. Take units sold in the last twenty eight days. Divide by twenty eight. That is your true speed. Check: You have a spreadsheet or tool showing units per day for each product. Number two: Compare that velocity to your supplier lead time. If your inventory days are lower than your lead time, you are at risk. Place the order now. Do not wait. Check: Your next purchase order is placed before your inventory days drop below your lead time. Number three: Flag any SKU where velocity has dropped more than forty percent over the last ninety days. That is your warning sign. Decide: promote, bundle, or stop buying. Check: You have a written decision for every slow moving SKU. Complete all three before the next daily episode. That is your challenge. That is how you stop guessing. That is how you protect your cash flow. That is The Voltage 3 Complete all three before the next daily episode.
Episode Summary
I tackle a common mistake many sellers make: relying on revenue instead of units when placing Amazon FBA purchase orders. This approach can lead to cash flow issues and dead stock. I share a clear method to calculate daily sales velocity for every active SKU, ensuring you make informed inventory decisions. Using David's case study, I illustrate the pitfalls of guessing on inventory and the importance of understanding true sales velocity. By taking units sold over the last twenty-eight days and dividing by twenty-eight, you can determine your daily sales speed. This simple calculation can save you from costly markdowns and lost sales. I also emphasize that bad data can render AI tools ineffective, leading to chaos instead of freedom. By the end of this episode, you'll have a solid framework for your next purchase order, eliminating guesswork and ensuring you know exactly how many units to order and when to reorder.

Your Amazon tools can read the data. They cannot act on it.
In a recent 143-seller AI challenge, 47% of sellers said the same thing: take Amazon Ads off my plate first. Almost every tool answers with another read-only report you still have to act on by hand. Caiman Data AI is different. 85 Read + Act tools on Amazon's own APIs run the analysis, put the recommendation and the trade-offs in front of you, and write the change back to Amazon on your go. You stay in the CEO chair.
Amazon Ads comes off your plate first
47% of sellers want AI to take over Amazon Ads before anything else. Full campaign audits, bids, placements, negatives, and bulk changes run under your supervision instead of eating your week.
Escape the read-only trap
Downloading reports is not automation. Read + Act tools publish listing fixes, bid changes, and reorder calls straight back to Amazon, previewed before anything ships.
Time back, pointed at the exit
Sellers in that challenge ranked scale and exit as their top two goals. The same stack saves us 17 hours a week and an average of $26,400 a year across our 30 brands, and those hours go into building an asset a buyer wants. Our largest client exit: $72M.
