In Which kind of Industries chatbots can help?

The top 5 industries which use chatbot are given below:

  • Chatbot Application for E-Commerce Industry: The global eCommerce industry has experienced remarkable growth. In 2017, worldwide retail eCommerce sales reached $2.3 trillion, and projections indicate that e-retail revenues will double, reaching an impressive $7.39 trillion by 2025. This exponential expansion has posed significant challenges for traditional customer support and sales methods such as phone calls, emails, and social media due to the sheer scale of the demand. Even businesses relying solely on these three channels for their eCommerce platforms have encountered formidable hurdles.
    The truth is, there’s a shortage of support representatives and sales personnel to meet the escalating demands. For instance, consider India, where the number of internet users is projected to surge from 481 million in December 2017 to a staggering 1.134 billion by 2025. In parallel, India’s eCommerce market is anticipated to skyrocket from $21.9 billion in 2018 to a substantial $200 billion by 2027. In the quest for success, particularly at scale, businesses have recognized that fully human-driven support and sales systems are no longer feasible. Our experience working with various eCommerce enterprises, ranging from $450 million industry leaders to budding Shopify startups, underscores the manifold benefits of deploying chatbots on their platforms. Conversational commerce chatbots offer multifaceted advantages to eCommerce industries, enabling increased revenue generation, time savings, shortened sales cycles, enhanced conversion rates, and improved cross-platform performance. Moreover, chatbots transcend language barriers, catering seamlessly to a globally diverse audience.
  • Medicine Industry-Chatbots have diverse applications in the healthcare sector, particularly in streamlining front office operations. Patients can proactively provide information to chatbots, which their attending nurses or doctors can utilise to minimise avoidable readmissions and arrange post-discharge follow-ups. These bots play a pivotal role in optimising admission, discharge, and transfer processes, scheduling patient consultations, and facilitating referrals. Moreover, chatbots possess the capability to consolidate information sources, creating a unified system of records. This seamless data transfer from legacy systems to modern databases not only saves time but also reduces operational costs. Incorporating alerts is an inherent function of medical industry chatbots. They can promptly notify hospital staff when patients require assistance and relay crucial updates regarding a patient’s condition or emergencies, all accessible through mobile devices. This efficiency can translate into significant time savings, potentially saving thousands of working hours annually for hospitals and physicians, ultimately alleviating the workload on medical professionals and enhancing the overall experience for patients.
  • Chatbot Application for Human Resource-The Human Resources (HR) industry plays a pivotal role in a company’s long-term success, with responsibilities extending far beyond the spotlight of hiring. While recruitment often takes centre stage, HR teams are entrusted with numerous behind-the-scenes tasks that significantly impact the organisation’s bottom line. These encompass vital functions such as ensuring legal compliance, conducting audits, resolving conflicts, crafting policies, optimising processes, delivering training, and nurturing leadership development. Given the critical nature of these responsibilities, organisations aspire for their HR teams to adopt a proactive and forward-thinking approach. However, this objective is frequently elusive. Recent research has revealed that approximately 40-50% of HR professionals’ time is consumed by talent management and addressing internal inquiries. This allocation of resources detracts from valuable time that could be more strategically employed for planning, strategizing, talent acquisition, and talent development. HR chatbots present a solution, capable of handling a spectrum of tasks ranging from generating interest and initial screening to managing background checks and assessing candidate qualifications. Chatbots also assist new hires in completing essential paperwork, acquainting themselves with team members, and addressing company-related queries even before their official onboarding, thus optimising HR’s efficiency and effectiveness.
  • Chatbot Application for Travel Industry-Chatbot stands ready to field inquiries and generate leads around the clock as there are national as well as international tourists so working by a human for a limited time period as in the stipulated business hours results in loss of potential customers. Moreover, chatbots are tireless, impervious to off-days or fluctuations in customer service quality.
    Travel chatbots not only gather customer data efficiently but also seamlessly synchronise it with your Customer Relationship Management (CRM) system in real-time. This ensures that no valuable information slips through the cracks, empowering you to leverage it for personalised interactions when the same customer returns in the future.
  • Banking Industry –In the banking sector, Chatbots for Banking represent a paramount source of data-driven insights, a facet of utmost significance. Chatbots empower companies to base their decisions on data, encompassing sales, marketing, trends, and product launches, all gleaned from the substantial data repository curated by these bots. Consequently, this translates into heightened customer loyalty, optimised resource allocation, and accelerated growth through conversational analytics.
    Bots, alongside their analytical capabilities, significantly diminish the time spent on operational tasks. They expedite the delivery of critical information and metrics, enabling your company to shift its focus from reacting to the present to robustly planning for the future.
