Safety Stock Calculator and Configuration

What This Sidekick Query Does

Help me calculate and configure optimal safety stock levels for my Shopify store products. I want to protect against stockouts while minimizing excess inventory carrying costs.

Please perform the following calculations:


  Gather input data for each SKU or product category [CATEGORY_LIST]:
    
      Average daily sales over the past [LOOKBACK_DAYS] days.
      Standard deviation of daily sales (demand variability).
      Average supplier lead time in days for [SUPPLIER_LIST].
      Standard deviation of lead time (supply variability).
      Desired service level: [SERVICE_LEVEL] percent.
    
  
  Calculate safety stock using the appropriate formula:
    
      Basic method: Safety Stock = Z-score x Average Daily Sales x Square Root of Lead Time.
      Advanced method: Safety Stock = Z-score x Square Root of (Lead Time x Demand Variance + Average Demand Squared x Lead Time Variance).
      Choose the method that best fits my data quality and variability.
    
  
  Present results in a table:
    
      SKU, product name, average daily demand, lead time, demand variability, lead time variability.
      Calculated safety stock in units.
      Current stock on hand versus recommended total stock (safety stock plus cycle stock).
      Cost of holding the recommended safety stock at [HOLDING_COST_RATE] percent annually.
    
  
  Scenario analysis:
    
      Show how safety stock changes if I increase service level to [HIGHER_SERVICE_LEVEL] percent.
      Show the cost savings if I accept a lower service level of [LOWER_SERVICE_LEVEL] percent.
      Impact of reducing lead time by [LEAD_TIME_REDUCTION] days through a different supplier.
    
  
  Configure the calculated safety stock levels as minimum thresholds in my store.
  Set up a [REVIEW_FREQUENCY] review cycle to recalculate as demand patterns change.


Please identify the top [TOP_N] products where I am most at risk of stockout based on current levels versus calculated safety stock.
