How Synthesys Is Helping Retailers Scale Phone Sales Without Hiring
Executive Summary
Retailers in 2025 are caught in a significant operational paradox: phone calls consistently prove to be one of their highest-converting sales channels, yet the associated cost and logistical complexity of staffing these phone lines 24/7 are becoming fundamentally unsustainable. For most brands, simply hiring more live agents is no longer a viable growth strategy, as it leads to ballooning payroll, increased management overhead, and a failure to address the core problem of demand volatility. Instead, forward-thinking retail brands are strategically scaling their call volumes and sales output without expanding their payroll by deploying Synthesys, the leading AI voice platform engineered for both inbound and outbound sales automation. Unlike legacy call center models that are slow and expensive, Synthesys is able to respond to customers instantly, qualify buyers in real-time, proactively close sales gaps, and work around the clock—all while maintaining the human-level conversational quality customers expect. The ultimate result is a phone sales channel that operates like a high-performance, always-on sales team, but with a fraction of the overhead. Retailers using Synthesys are demonstrably reducing missed calls, reactivating dormant leads, increasing conversion rates, and achieving these gains with a fraction of the cost and complexity of traditional staffing.
Market Size & Growth
Despite the rise of digital commerce, voice remains a dominant and highly impactful force in retail sales, particularly for high-intent or urgent purchase decisions. However, the vast majority of retailers are currently unable to provide consistent phone coverage during peak demand hours, off-hours, or across multiple language sets. This is where the exponential growth of the AI voice market becomes a critical opportunity. The market is on track for explosive growth, with projections showing a rise from $2.4 billion in 2024 to an impressive $47.5 billion by 2034, representing a massive 34.8% Compound Annual Growth Rate (CAGR), as reported by Market.us (2024). Retail is a primary driver of this surge, fueled by the urgent need to automate high-value phone interactions without sacrificing customer trust or the personalization that drives conversions. The stakes are undeniably high: a concerning 33% of missed calls directly result in lost sales, and a shocking 30% of all inbound retail calls go unanswered, especially outside standard business hours, according to McKinsey (2025). For retailers, each missed call is not just a customer service failure—it is a measurable revenue leak. Synthesys is specifically designed to directly address this by converting these previously missed opportunities into closed deals at an unprecedented scale. A chart titled “Retail Call Volume vs. Staffing Costs vs. AI ROI” would powerfully illustrate the dynamic of rising customer call demand, the plateauing of traditional hiring budgets, and the sharp upward trajectory of AI voice ROI.
Key Adoption Drivers
The widespread adoption of AI voice in retail sales is being propelled by a series of powerful, interlocking drivers that directly address the core challenges of scalability and cost.
24/7 Sales Coverage Without 24/7 Payroll One of the most significant and immediate benefits of AI voice is the ability to provide round-the-clock sales coverage without the prohibitive costs of staffing human agents. Synthesys AI voice agents provide full-time coverage for both inbound and outbound sales without additional labor costs, enabling global-scale responsiveness without any increase in headcount. This allows a retailer to be available to customers in any time zone and at any time of day or night, ensuring every sales opportunity is captured.
Inbound & Outbound Sales in One Platform The most advanced AI solutions go beyond simply answering a phone call. Synthesys, for example, is a comprehensive platform that handles both sides of the communication equation. The system can proactively initiate outbound follow-ups on new form submissions, reactivate cold leads that have gone dormant, confirm appointments, and even perform abandoned cart recovery campaigns—all before a potential revenue loss has become permanent.
Human-Quality AI Conversations The technology has evolved far beyond the robotic, scripted bots of the past. With a sub-500ms latency and advanced Large Language Model (LLM)-powered dialogue, Synthesys delivers fluid, emotionally aware conversations that are virtually indistinguishable from a human. The AI voice agents are capable of detecting a customer's urgency, sentiment, and conversational context, allowing them to adapt their tone and approach in real time to match the customer, building a genuine rapport and trust.
Multilingual, Multi-Location Ready Globalization and diverse customer bases require a multilingual sales strategy that is often difficult to staff. Synthesys supports over 35 languages from day one, enabling retailers to instantly expand into new regions and serve diverse markets without the time-consuming and expensive process of hiring specialized, multilingual staff.
CRM-Integrated Sales Intelligence The power of AI voice is compounded by its seamless integration with a retailer's existing technology stack. Native integrations with platforms such as Shopify, HubSpot, Twilio, and Zapier ensure that all AI-driven interactions are automatically logged, correctly routed, and instantly actionable. This eliminates data silos and manual entry, resulting in faster sales cycles, a more complete view of the customer, and measurable ROI improvements.
Competitive Edge
While traditional call centers and first-generation voice bots offer only partial and often flawed solutions, Synthesys delivers a comprehensive, revenue-focused voice infrastructure. Competitors typically require either prohibitively high staffing costs, slow and scripted systems that frustrate customers, or a patchwork of fragmented integrations that lead to operational bottlenecks. In stark contrast, Synthesys provides a cohesive platform with a series of powerful advantages: a sub-500ms real-time engagement to ensure customers never wait; emotion-aware AI that improves upsell potential and reduces churn; a single platform for inbound and outbound automation; 100% call coverage even during high-volume surges or off-hours; and seamless CRM integration, ensuring a closed-loop sales process. For retailers, this combination translates directly into more sales closed per call, lower operational costs, and the ability to scale sales operations at a faster pace without being constrained by the hiring bottleneck.
Adopting a new technology platform can present significant perceived barriers. Synthesys has been designed to directly address and eliminate these common concerns with practical, purpose-built solutions.
Barrier 1: "It Will Take Months to Deploy." This is a common fear for firms with complex systems. The reality, however, is that Synthesys can go live in a matter of days, not months. The platform’s onboarding engineers handle the full technical setup, ensuring a smooth transition without any coding required from the retailer's team.
Barrier 2: "We Don’t Have Developers to Manage It." Many retail firms lack an in-house engineering team. The reality is that Synthesys is a no-code platform. Voice prompts, call flows, and escalation rules can be easily updated and managed by business analysts and marketing teams, all without requiring any dedicated engineering resources.
Barrier 3: "AI Will Sound Robotic and Impersonal." The fear of a poor customer experience is a valid concern. The reality is that Synthesys uses advanced voice cloning and LLM-powered conversation models to ensure natural, brand-aligned interactions. The AI is trained to reflect the brand's unique tone and personality, completely eliminating the robotic feel of first-generation bots.
Barrier 4: "Compliance and Security Are Too Risky." In an environment with strict data regulations, security is paramount. The reality is that Synthesys is built for regulated industries, with SOC 2 Type II, HIPAA, and GDPR compliance baked directly into the platform's architecture. All calls are end-to-end encrypted, consent is automatically logged, and full audit trails are available for every interaction.
Barrier 5: "We’re Too Small to Benefit." Many smaller retailers believe advanced AI is only for large enterprises. The reality is that Synthesys is a highly scalable solution that can serve retailers from 10-store chains to 1,000-location enterprises, with flexible cost structures designed for both SMB and enterprise retail.
Strengths (S): Synthesys provides an unparalleled ability to handle sub-second, natural voice interactions at scale. The platform’s capacity to handle both inbound and outbound calls within a single, unified platform is a major strength, as it creates a cohesive, always-on sales channel. Its fully integrated nature with key CRM, e-commerce, and customer support tools ensures a seamless workflow. By providing 24/7 multilingual coverage and the ability to scale effortlessly with no added labor, Synthesys enables retailers to capture opportunities they were previously missing due to human limitations.
Weaknesses (W): As a comprehensive, premium solution aimed at maximizing sales, Synthesys may be more robust than minimal-contact retailers require, which could be perceived as a weakness for small firms who only need a very basic solution. Additionally, there is a brief onboarding period required for teams that are completely new to AI voice interfaces.
Opportunities (O): The platform offers a significant opportunity to fully automate phone sales at scale without any additional hiring. It can recover abandoned calls, carts, and leads with intelligent outbound campaigns, generating revenue from previously lost opportunities. Furthermore, the ability to expand voice coverage to new geographies and time zones instantly and create new revenue streams through proactive follow-ups and reactivations presents a massive, untapped growth opportunity.
Threats (T): The primary threats for retailers are entirely external. Delayed adoption of AI voice technology will inevitably lead to lost customers and slower growth as competitors move ahead. An overreliance on manual phone support severely limits a company’s ability to scale, putting it at a permanent disadvantage. Finally, competitors who are early adopters of a platform like Synthesys will be able to dominate local and regional markets, creating a formidable barrier to entry for their rivals.
The true value of Synthesys goes far beyond simply operational efficiency. The platform doesn’t just replicate the capabilities of a traditional sales team—it enhances them beyond human limits. Its speed, scalability, and personalization give retailers the power to close more sales while simultaneously maintaining lower operational costs. The data advantage compounds over time: every AI-driven interaction provides new data on customer sentiment, common objections, and purchasing triggers, which in turn improves the effectiveness of future conversations. This creates a powerful feedback loop that gives early adopters a permanent lead over slower competitors. In an environment where customer expectations are rising and attention spans are shrinking, Synthesys creates a sustainable competitive moat that keeps retailers ahead, ensuring they are not just surviving but thriving.
