It’s not a messaging app here — it’s infrastructure. And for businesses, it’s the most direct line to every customer. 500M+ WhatsApp users in India India accounts for the single largest WhatsApp user base in the world — more than the entire population of the United States. 98% Message open rate WhatsApp messages are opened nearly 3× faster than emails and 2× faster than SMS. Attention is already there. 4.2 hrs Daily screen time per user The average Indian smartphone user spends over 4 hours daily on their phone. WhatsApp is their most-used app. ₹14.3T India’s digital economy by 2027 Brands that win digital customer communication now will capture a disproportionate share of this growth. 💡 Key Insight India’s top brands are already making the shift. Home services businesses handle 40,000+ bookings per month via WhatsApp with zero call center involvement. Financial institutions have collected ₹7.6 Crore through automated WhatsApp payment reminders. Travel brands have cut cost-per-order by ~50% with interactive WhatsApp campaigns. The window to be an early mover in your industry is closing fast. The traditional customer communication stack — call centers, bulk SMS, email blasts — was built for a different era. Today’s Indian customer expects instant responses, 24/7 availability, and conversations that feel personal. WhatsApp Business delivers all three at a fraction of the cost of legacy systems. 02Channel Comparison Why WhatsApp wins overevery other channel The data doesn’t lie.

BLUEPRINT SERIES / 2026 Turning call queues into self-service. How Voltas built a 24/7 WhatsApp service booking system to eliminate wait times and handle 160,000+ requests with zero agent involvement. 160K+ Service Requests Handled 40K+ Requests Per Month 24/7 Availability for Customers A JOINT OPERATIONAL STUDY BY SINCH X VOLTAS 02 THE OPERATIONAL CHALLENGE STRATEGY ANALYSIS Legacy models reached their limit. Voltas faced a critical operational ceiling. As the customer base expanded, the traditional call center model began to fracture under the weight of manual coordination and high-frequency service requests. 01 The Queue Crisis High call traffic led to extended wait times, creating a negative cycle where customers were stuck in long queues for simple bookings. 02 The Time Barrier Service was restricted to business hours. Without 24/7 access, customers had no way to schedule urgent or after-hours repairs. 03 Manual Data Strain Relying on human agents for every ticket led to coordination errors. Manual entry caused gaps that reduced customer satisfaction. 04 Wait-Time Fatigue Navigating IVR menus and waiting for a human voice became a major pain point. Users demanded an instant, app-like experience. The goal was to transform a manual bottleneck into an instant, automated self-service win. 03 STRATEGIC ARCHITECTURE SINCH | VOLTAS BLUEPRINT The “Modern Service Desk” Logic Voltas didn’t just add a chat button; they re-engineered the booking journey. By utilizing WhatsApp Flows, the team replaced fragmented human conversations with a native, form-based engine that lives entirely inside the chat interface. 🔄 Native Flow Architecture By moving selection menus for products and symptoms into WhatsApp’s native interface, we eliminated the friction of external redirects and slow-loading websites. 🔗 Seamless Data Sync The system integrates directly with the Voltas backend to auto-fetch account details. For new users, smart PIN-code detection automatically maps the city and state for error-free booking. 🤖 Autonomous 24/7 Operations The entire journey is human-independent. This ensures that a service request made at 2:00 AM is handled with the same speed and accuracy as one made during peak business hours. The Strategy: Turn a 10-minute manual call into a 90-second digital breeze, offloading 40,000+ requests per month to an automated system. 04 THE SELF-SERVICE JOURNEY OPERATIONAL FLOW How the engine works. A fully automated WhatsApp Flow replaces the entire call center booking process. From issue selection to ticket confirmation, the user stays within a single, native interface. 01 📋 Product & Issue Selection Customers select their specific product category, issue type, and symptoms from structured, easy-to-tap menus. 02 📍 Address Confirmation The system auto-fetches saved details from the backend. Users can add new locations with PIN-based auto-detection of city and state. 03 💬 Details & Diagnostics Users can add specific comments or upload photos of the product to provide technicians with pre-visit context. 04 ✅ Instant Ticket Generation The request is registered natively. A confirmation message with a unique Ticket ID is sent back to the user instantly. The entire journey is completed in under 90 seconds, operating 24/7 with zero human intervention required. 05 THE TECHNICAL ENGINE INFRASTRUCTURE SPECS Intelligence beneath the interface. The success of the Voltas service desk is built on deep backend integration. By connecting WhatsApp directly to the core database, we enabled a level of automation that eliminates human error and manual data entry. 🔗 Seamless Backend Synchronization The system is natively integrated with the Voltas backend to auto-fetch existing customer account details and saved service addresses instantly. Zero manual data entry for returning customers. Real-time verification of product warranties and history. Direct synchronization with existing CRM data. 📍 Smart PIN-Code Detection For new users or secondary locations, the system utilizes a proprietary PIN-based logic to maintain data integrity across the service map. Automatic detection of Metro, City, and State from a 6-digit PIN. Elimination of typing errors in geographic data. Instant mapping to the nearest available service center. 📋 Native Form-Based Architecture By using WhatsApp Flows, we replaced clunky chatbot menus with structured, multi-step forms that feel native to the mobile interface. Reduced context switching for the end user. High-speed navigation through product sub-categories. Consistent data formatting for backend ticket creation. This technical foundation allows Voltas to process over 40,000 monthly requests with zero human intervention required at the point of booking. 06 THE PERFORMANCE DATA RESULT SCORECARD Self-service at massive scale. Measured since the deployment of WhatsApp Flows, the impact on Voltas’ operational efficiency has been immediate and transformative. 160K+ Total Service Requests Over 160,000 service requests have been successfully registered via the WhatsApp Flow to date. 40K+ Monthly Volume Consistently handling over 40,000 automated requests every single month. ZERO Agent Involvement 100% of the booking journey is handled by the automated flow, from start to ticket generation. 🕐 24/7 Availability Customers can book anytime, day or night, with zero wait or queues. 📉 Operational Relief Drastically reduced call center load and manual scheduling errors.

Before we started using WhatsApp, it was hard for our team to help everyone at the same time. Here are the main problems we fixed for you. 📞 Phone Lines Were Full During the hot summer months, too many people called at once. This meant you had to wait a long time just to talk to someone. 🌙 Closed After 6 PM Our office used to close in the evening. If your AC broke at night, you could not even start a booking until the next morning. 👤 Too Much Manual Work Every booking needed a person to type in the details. This was slow and sometimes led to mistakes with addresses or times. ⏱️ Waiting Was Frustrating No one likes waiting on hold. You wanted a way to book a repair instantly on your phone without talking to anyone. SERVICE IS NOW LIVE Voltas has introduced WhatsApp Service. We moved our entire service desk into a simple chat. Now, Voltas handles everything for you automatically, 24 hours a day. 📋 It finds your product No more searching.

Executive Brief SAP ECC Support Is Ending. Enterprises Must Decide What Comes Next. For more than two decades, SAP ECC has powered finance, supply chains and enterprise operations across thousands of organisations. However, SAP’s innovation strategy has now shifted toward SAP S/4HANA, designed for real-time analytics, automation and AI-driven business processes. THE CHALLENGE Organisations still running SAP ECC are now approaching a critical decision point — whether to continue operating on legacy ERP systems or begin planning their transition to S/4HANA. 75% of SAP customers worldwide are still operating on SAP ECC environments. 2027 SAP ECC mainstream maintenance ends December 31, 2027, after which organisations face unsupported systems and increased operational risk. 85% of enterprise ERP deployments are expected to shift toward cloud-based platforms in the coming years. The timeline for ERP modernisation is no longer theoretical. Organisations that begin planning their transition early gain time to evaluate migration strategies, preserve customisations and optimise their digital transformation. Those that delay may face increasing competition for SAP expertise, higher migration costs and compressed project timelines. The Cost of Staying on SAP ECC While SAP ECC continues to support critical business operations, legacy ERP systems introduce operational inefficiencies, rising maintenance costs and increasing security exposure. For many organisations, the financial impact of delaying ERP modernisation is already measurable. Data Silos & Delayed Reporting 4.3 Days Executives receive operational reports that are on average 4.3 days old, slowing decision-making in rapidly changing markets. High Maintenance Burden 72–80 % IT teams running legacy ERP systems spend the majority of their technology budgets maintaining existing infrastructure instead of investing in innovation. Limited AI & Automation 2.5 × Faster Organisations using AI-enabled ERP platforms achieve up to 2.5× faster insights and significantly reduce manual finance operations. Security & Compliance Risk ₹17.9 Crore The average cost of an ERP-related data breach for Indian enterprises, with legacy on-premise systems significantly more vulnerable. 4.3d Delay 80% Maintenance 2.5× Faster ₹17.9Cr Risk The Hidden Cost of Standing Still A large Indian manufacturer running SAP ECC estimated their annual “cost of standing still” — including deferred innovation, manual workarounds and compliance exposure — at ₹8–12 crore per year. SAP S/4HANA • CLOUD TRANSFORMATION SAP S/4HANA: Modernising Enterprise ERP SAP S/4HANA Cloud Private Edition combines ERP software, cloud infrastructure and managed services into a single transformation program designed to help organisations modernise their ERP landscape while preserving operational continuity and existing customisations. Unlike traditional ERP upgrades, SAP S/4HANA Cloud Private Edition provides a structured pathway for organisations to transition from legacy systems to a cloud-enabled ERP platform designed for real-time analytics, automation and AI-driven decision-making. ☁️ Private Cloud ERP S/4HANA Cloud Private Edition provides a modern ERP foundation while allowing organisations to retain critical business processes and customisations developed over years of operation. 🌐 Certified Cloud Infrastructure Delivered through hyperscaler infrastructure such as Microsoft Azure, AWS or Google Cloud with enterprise-grade reliability and scalability. ⚙️ Managed SAP Operations Infrastructure and technical operations are managed by SAP specialists, allowing internal IT teams to focus on innovation instead of system maintenance. KEY METRICS 30% Reduction in IT operational costs within the first two years of deployment. 162% Average three-year ROI achieved through modernised ERP operations. 2.1 Years Average payback period for organisations adopting SAP S/4HANA Cloud. Your Path from SAP ECC to S/4HANA Every organisation’s ERP landscape is unique. The transition from SAP ECC to S/4HANA can follow multiple migration approaches depending on system complexity, customisations and transformation goals. Approach Timeline Risk Level Custom Code Best For Brownfield (System Conversion) 6–12 months Low Preserved Complex ECC environments Bluefield (Selective Data Migration) 9–15 months Medium Partially redesigned Process harmonisation Greenfield (New Implementation) 12–18 months Higher Rebuilt Full transformation ★ Why Enterprises Choose Embee 500+ SAP implementations across manufacturing, BFSI, pharma, retail and public sector. 96% On-time delivery across SAP transformation projects. 30 Days Initial scope delivery for SAP S/4HANA transformation programs.

Organisations that begin planning their migration early gain the flexibility to modernise processes, optimise customisations and control transformation costs.
