Challenges & solutions

Problem
number

Facing soaring demand, QuickBite confronts critical customer support challenges. With its rapidly growing customer base and expanding geographic footprint, QuickBite has encountered a series of pressing issues within its customer support operations:


  • Call Center Overload
    Over six months, the volume of incoming calls has surged by 120%. During peak hours — particularly at lunch and dinner — operators have struggled to handle the influx, resulting in frequent overloads.


  • Long Wait Times
    Customers often faced wait times of 5 to 7 minutes, fueling frustration and a rise in negative reviews on the App Store and Google Play.
Problem

  • Repetitive Inquiries
    More than 60% of calls were routine questions, such as:

    “Where is my order?”

    “How do I cancel or modify my order?”

    “Repeat my last order”

    “What ingredients are in this dish?”

    “Do you deliver to my area?”

  • Order Processing Errors
    High call volumes and the fast-paced environment led to human errors — incorrect dishes, wrong addresses, or inaccurate delivery times — directly impacting customer satisfaction.

  • Rising Staffing Costs
    To manage the increased workload, QuickBite had to expand its call center staff, driving up operational costs without a matching improvement in service quality.

All these challenges highlighted the urgent need to automate customer service processes, particularly voice interactions, to maintain efficiency and deliver a smoother customer experience.

QuickBite approached us with a clear mission:

  • Reduce the workload for support operators;
  • Cut the average handling time for incoming calls;
  • Boost customer satisfaction with fast, accurate voice support;
  • Automate order placement and responses to frequently asked questions.

Solution
part3

To meet these goals, we developed and deployed an AI Voice Assistant fully integrated into QuickBite’s system. Key features of the solution include:


  • Natural speech recognition
    Accurately understands and processes customers’ spoken language.

  • Contextual memory
    Remembers previous orders and can suggest repeating or modifying them.

  • End-to-end order processing
    Enables customers to place orders entirely through the voice menu without human intervention.

  • CRM and logistics integration
    Automatically checks order status and estimated delivery times, with the option to transfer to a live operator if needed.

  • Multilingual support
    Available in 140 languages.


The results exceeded expectations. Within three months of implementation, QuickBite reduced its call center workload by 67%, cut average call response time from two minutes to just 15 seconds, and saw a 21% increase in customer satisfaction based on internal Net Promoter Score (NPS) data. Remarkably, 40% of orders were placed entirely through the AI Voice Assistant.



By adopting this technology, QuickBite not only streamlined its operations but also set a new standard for customer service — marking a significant first step in its broader digital transformation journey.
