illion Digital Tech Solutions dramatically improved on the existing collection results in all base measures and collection KPI’s, while reducing OPEX by 80%


Success was based on achieving the same results as the Advisor-lead campaigns with a lower OPEX. In addition, churn and customer complaints were also monitored during this time.


Digital Tech Solutions leveraged its 26+ years in Automated Communications and Payments to provide Vodafone with a best-in-breed solution. By taking the time to understand Vodafone’s requirements and success criteria, Digital Tech Solutions launched a 3-month proof-of-concept pilot for 20% of Vodafone’s collection customers. After 4 weeks of operation, the trial was deemed a success, volumes were increased and new solutions launched.

KPI metrics

  • Reduce OPEX by reducing Advisor-lead calls
  • Reduce debtor days and overall debt risk
  • Reduce involuntary churn
  • Increase number of customers on Direct Debit
  • Increase cash collected
  • Increase volume of payments

Customer solutions included:

  • Collections – For customers whose bill is overdue, Digital Tech Solutions places an automated outbound call or SMS that provides the ability to make full account payment. Should the customer not be available, the customer can call back the number and receive the same experience.
  • Direct Debit – Customers whose Direct Debit has been cancelled or failed, are contacted allowing them to make payment for the overdue amount and setup a new DD instruction.
  • High Usage Alerts – Notify customers whose usage has increased unusually mid-billing period. The solution provides a running total which allows customers to adjust their usage, make a part-payment or simply confirm the usage is actually theirs.


Digital Tech Solutions employed a consultative approach with Vodafone to understand their drivers and how an automated solution would work within (and enhance) their wider collection strategies.

Digital Tech Solutions worked with Vodafone to design bespoke solutions that have been easy to integrate, and deliver the forecasted results.

Three key factors were highlighted during the requirement stage that were key to success:

  1. Simplicity (achieving both speed and trust)
  2. Consistency
  3. Future-proof

The existing collection strategy leveraged high cost, Advisor-lead outbound activity that generated low contact rates. Due to the high OPEX associated with live agents, Vodafone could only contact a small percentage of its overdue customers. Vodafone were looking for a significant reduction in OPEX across its collection’s activity without impact to key collection metrics.


  • Overall the self-serve pilot has supported the need and benefits for a fully automated collections experience
  • Avoids a potentially embarrassing and awkward discussion with an Advisor (customers feel obliged to explain their personal situation)

An automated 24/7 self-serve option still offers Vodafone customers great service – fact surveys reveal it is the preferred customer option.


Digital Tech Solutions dramatically improved on the existing collection results in all base measures and collection KPI’s, while reducing OPEX by 80%:

  • 9% reduction in involuntary churn from never-paid customer type
  • Six-fold increase in cash collected
  • 80% reduction in operating expenses
  • 20% increase in customer interaction rates

Customer experience surveys have shown less than a third of customers preferred using an Advisor over Vodafone’s automated services.

“Working with illion Digital Tech Solutions has allowed Vodafone to create a highly scalable solution, offering [our customers] 24/7 self-service, compared to traditional contact center methods. “”.
