Questions

What is a reorder point?

A reorder point is the stock level at which you should place a new order. It is calculated as your average usage during the supplier lead time, plus a safety-stock buffer for demand spikes or delays. When on-hand stock falls to the reorder point, ordering then means new stock arrives before you run out.

What is EOQ (economic order quantity)?

EOQ is the order size that minimises your total cost of ordering and holding stock. Order too little too often and ordering costs pile up; order too much and holding costs (and tied-up cash) grow. EOQ = the square root of (2 × annual demand × cost per order ÷ annual holding cost per unit) balances the two.

What is in the paid planner?

A ready-to-use spreadsheet (Excel & Google Sheets): a per-SKU table computing reorder points, reorder-now flags, suggested order quantities (EOQ), and stock value, plus a dashboard of total cash tied up and what to reorder — delivered instantly after checkout. AI-assisted, human-built; not financial advice.
