🛍️ Quick Commerce SLA Explained: PPI, Fill Rate, True Fill Rate, PNA & DS Variance – A Complete Guide for Store Managers

Quick commerce (10–20 minute delivery model) has completely transformed retail operations.

But behind every fast delivery is a high-pressure store environment where performance is measured every minute.

For store managers and captains, success is not just about dispatching orders—it’s about meeting strict SLA (Service Level Agreement) metrics.


👉 These SLA directly impact:

  • Customer experience
  • Store performance
  • Manager evaluation
  • Business profitability

In this guide, we’ll break down the most important quick commerce KPIs:

👉 PPI
👉 Fill Rate
👉 True Fill Rate
👉 PNA
👉 DS Variance


⚡ What is Quick Commerce SLA?

SLA (Service Level Agreement) defines the performance standards expected from a store.

In quick commerce, SLAs are extremely strict because:

  • Delivery time is short
  • Customer expectations are high
  • Competition is intense

👉 Even small inefficiencies can lead to:

  • Order cancellations
  • Poor ratings
  • Revenue loss

📊 1. PPI (Picking Per Item)

📌 What is PPI?

PPI measures the average time taken to pick one item in an order.

👉 It reflects the efficiency of store operations and staff speed.


🧮 Formula:

PPI=Total Picking TimeTotal Items PickedPPI = \frac{Total\ Picking\ Time}{Total\ Items\ Picked}


🎯 Standard Benchmark:

👉 1 item = 16 seconds (approx.)


📉 Why PPI Matters:

  • Directly impacts delivery time
  • Affects rider waiting time
  • Influences customer satisfaction

⚠️ If PPI is High (Bad Performance):

Store manager must analyze:

  • Staff efficiency issues
  • Poor store layout
  • Inventory misplacement
  • Lack of training

👉 Daily meetings often require SM to justify why PPI is not achieved.


💡 How to Improve PPI:

  • Proper bin location mapping
  • Staff training and zoning
  • Fast-moving SKU placement
  • Reduce clutter

📦 2. Fill Rate

📌 What is Fill Rate?

Fill rate measures how many ordered items were successfully fulfilled.


🧮 Formula:

Fill Rate=Items DeliveredItems Ordered×100Fill\ Rate = \frac{Items\ Delivered}{Items\ Ordered} \times 100


📊 Example:

  • Order received: 2 items
  • Delivered: 1 item

👉 Fill Rate = 50%


🎯 Why It Matters:

  • Shows inventory availability
  • Impacts customer satisfaction
  • Affects repeat business

⚠️ Low Fill Rate Means:

  • Poor inventory management
  • Stock mismatch
  • Operational inefficiency

🔍 3. True Fill Rate

📌 What is True Fill Rate?

True Fill Rate is a more accurate version of Fill Rate.

It considers:

  • Missing items
  • Wrong items
  • PNA (Product Not Available)

👉 It reflects the real customer experience.


🧮 Formula:

True Fill Rate=Correct Items DeliveredTotal Items Ordered×100True\ Fill\ Rate = \frac{Correct\ Items\ Delivered}{Total\ Items\ Ordered} \times 100


📉 Why True Fill Rate is Important:

  • Captures operational errors
  • Tracks quality, not just quantity
  • Impacts customer trust

⚠️ If True Fill Rate Drops:

Possible reasons:

  • Wrong picking
  • Poor SKU identification
  • Inventory inaccuracies
  • Staff negligence

🚫 4. PNA (Product Not Available)

📌 What is PNA?

PNA occurs when:

👉 An item is ordered but not available in the store during picking


📊 Example:

  • Order received: 2 items
  • 1 item not found → marked as PNA

⚠️ Why PNA is Critical:

  • Reduces Fill Rate
  • Impacts True Fill Rate
  • Leads to customer dissatisfaction

🔍 Root Causes of PNA:

  • Stock not updated in system
  • Misplaced products
  • Theft or shrinkage

💡 How to Reduce PNA:

  • Regular inventory checks
  • Proper stock audit
  • Real-time system updates
  • Shelf discipline

📉 5. DS Variance (Delivery Stock Variance)

📌 What is DS Variance?

DS variance measures the difference between system stock and actual physical stock.


🧮 Concept:

DS Variance=System StockPhysical StockDS\ Variance = System\ Stock - Physical\ Stock


📊 When It Happens:

  • During daily audit
  • Due to PNA
  • Missing inventory
  • Incorrect stock adjustments

⚠️ Why DS Variance is Dangerous:

  • Leads to repeated PNA
  • Affects store accuracy
  • Impacts financial reporting

🔍 Causes:
