Measuring Mobile POS: 5 Essential KPIs

Retailers are increasingly switching to a mobile POS system or mobile checkout system: smart payment solutions via a tablet or smartphone enabling staff to scan products, process payments, and manage inventory — directly on the shop floor. The answer: measuring the right KPIs to focus on. Without data-driven insights, it remains guesswork whether your mobile POS contributes to higher sales and more efficient processes. Discover here the 5 most important KPIs you must monitor.

1. Increase transaction speed with Mobile POS

One of the biggest advantages of a mobile POS system is the quick processing of payments. Retailers like Zara and Apple use transaction time as a critical performance indicator.

Why is it important?

• Shorter transaction times reduce queues
• Higher customer satisfaction and more purchases per visit

What to measure?

• Average transaction time (in seconds) per POS type (mobile vs traditional)
• Number of customers served per hour via mPOS

Tip: Compare transaction times during different times of the day to fairly assess peak periods.

With a mobile checkout system, staff can assist customers directly on the shop floor to make payments, even before they possibly abandon their shopping. Forrester Research confirms that waiting times are the main reason for customers leaving without making a purchase. 

Why is this important?

• Higher conversion rate = immediate sales increase
• Fewer drop-offs = more efficient shop floor

What to measure?

• Conversion rate = (Number of purchases / Number of store visits) × 100
• Number of abandoned transactions on the shop floor (if measurable)

Tip: Monitor conversion rates separately for customers assisted via mobile POS versus fixed tills.

With mobile POS, staff can recommend additional products during the sales moment. Sephora actively uses Mobile POS to provide personalised advice to customers, thereby increasing the average order value (source: Glossy.co, 2021). 

Why is this important?

• Higher Average Order Value (AOV) means immediate revenue growth

What to measure?

• AOV Mobile POS = Total revenue via mobile POS / Number of mobile POS transactions
• Compare AOV with traditional checkout transactions

 Tip: Also analyse which upsell products perform best via mobile POS.

A smooth checkout process has a direct impact on customer satisfaction and brand perception. Retailers like Decathlon actively link Mobile POS to improvements in their Net Promoter Score (NPS) through in-store use of mobile payment options (source: Retail Technology Review, 2023). 

Why is this important?

• Satisfied customers return faster and recommend your store

What to measure?

• NPS scores per store or department where mobile POS is actively used
• Customer satisfaction specifically after mobile POS interactions via short surveys or QR codes

Tip: Evaluate at least quarterly for a reliable trend analysis.

With an mPOS solution, staff can assist customers more quickly and conduct more sales conversations on the shop floor. Best Buy reported a significant increase in staff efficiency following the introduction of Mobile POS (source: Retail Dive, 2022). 

Why is it important?

• More efficient staff increases both service quality and sales opportunities

What to measure?

• Customer interaction time / Total working hours × 100
• Sales per employee before and after mPOS implementation

Retailers who actively measure their Mobile POS performance can:

• achieve faster checkout processes
• increase customer satisfaction
• grow the average revenue per visitor
• deploy staff more intelligently
