Why a Great Amazon Margin Can Still Be a Bad Cash-Flow Decision

By Arnold Ji, Co-Founder of SKDK SPORT

An Amazon product can show a strong margin and still be a poor cash-flow decision.

The problem is often not the landed cost. It is an MOQ that forces the seller to hold months of inventory.

The Lean FBA Model

Many FBA sellers want a leaner model: start with a manageable quantity, replenish according to sales, reinvest the returns, and gradually add more products.

The logic makes sense. But choosing "20 days of inventory" alone is not enough.

A practical replenishment plan should consider:

• Average daily sales
• Production lead time
• International transit time
• FBA receiving and check-in time
• Safety stock
• Carton and freight economics

A Simple Reorder Point Principle

A simple planning principle is:

Reorder point = average daily sales x total replenishment lead time + safety stock

If the total replenishment cycle is longer than the inventory coverage, a lean order can quickly become a stockout — and a stockout costs both sales ranking and cash flow.

How We Support Rolling Orders and FBA

For selected standard products, SKDK SPORT can discuss smaller rolling orders where stock, packaging, and freight economics allow. We can also support FNSKU labeling, packing, carton preparation, and direct FBA shipments when applicable.

This applies to knee supports, ankle braces, wrist wraps, and other sports protection products that fit a fast-moving FBA catalog.

Our preferred path is to start with a focused product range, validate sell-through, establish a repeatable replenishment rhythm, and then expand.

The Best Order Quantity

The best order quantity is not always the factory MOQ or the smallest possible order.

It is the smallest economically sensible quantity that protects cash flow without creating unnecessary stockout risk.
