Hinglish AI calling agent confirms COD orders
before the return window opens.

The Sleep Company is India's leading sleep solutions brand, known for its SmartGRID technology across mattresses, chairs, and ergonomic furniture. With a nationwide customer base and high Cash on Delivery (COD) order volumes, the brand's operational performance depends critically on the efficiency of order confirmation and delivery coordination — particularly for high-value furniture orders where failed deliveries are especially costly.

We deployed a production-grade AI Humanoid Voice Calling Agent that replaced a manual calling operation costing $198 per day. The result was a transformation in every delivery metric: order confirmation speed, same-day confirmation rates, RTO reduction, and operational costs — while maintaining the premium customer communication quality the brand's customers expected.

Year2025

Built for the COD customer who expected a human call, the ops team making 200 calls a day manually, and the finance lead watching RTO rates drain margin.

Three people were living with the consequences of a slow, expensive manual confirmation process — a customer waiting days, a call center manager managing impossible volumes, and an operations VP watching RTO costs compound.

COD customer awaiting mattress delivery · Jaipur

COD customers placing high-value mattress orders waited 24 to 72 hours with no confirmation of whether the order had been processed. The absence of timely outreach created doubt, and in some cases, cancellations that a same-day confirmation call would have prevented.

Call Center Operations Manager · The Sleep Company

Call center teams handling hundreds of daily confirmation calls could not keep pace with order volume during peak periods. Despite the cost of a dedicated calling team, same-day confirmation targets remained out of reach — particularly on high-volume sale days.

VP Operations · The Sleep Company

A COD RTO rate of nearly 5% was generating significant reverse logistics costs on every failed furniture delivery. The manual calling operation was costing $198 per day and still only achieving same-day confirmation on 11% of orders — a cost and performance combination that was not sustainable.

💸 RTO rate and confirmation speed costing margin at scale

The Sleep Company's COD confirmation process was costing $198 a day and confirming only 11% of orders same-day.

Cash on Delivery order confirmation is a last-mile problem hiding as a customer service problem. For The Sleep Company, the human caller model had fundamental constraints: it operated within business hours, couldn't handle peak volumes during sale periods, and was producing same-day confirmation for only 11.66% of orders — leaving most customers in a 24-72 hour confirmation window that created anxiety, changed-mind cancellations, and ultimately, expensive RTO situations.

At $198 per day, the manual model was both inefficient and expensive. The AI solution needed to operate 24/7 at scale, speak in the Hinglish code-switching style that connected with The Sleep Company's diverse pan-India customer base, and execute complex in-call actions — scheduling delivery slots, verifying order details, creating CRM tickets — without human assistance.

A premium furniture brand's reputation for care and quality ends at the moment its confirmation call doesn't come for two days.

on both sides of the screen.

Customer Confidence

Reena receives a confirmation call the same day she orders — the AI sets accurate delivery expectations, confirms her availability, and schedules around her preferences. The premium brand experience extends to the first post-purchase touchpoint.

☎️

Operations Scaled Without Headcount

Deepak's confirmation pipeline now handles 200+ simultaneous calls around the clock — peak sale days, midnight orders, and high-volume weekends are processed without degradation or backlog.

📊

Margin Protection

Amitabh's RTO rate dropped because the AI confirms orders the moment they're placed, sets delivery slots accurately, and sends reminders. Every prevented return is direct margin recovery.

💸

Cost Structure Transformed

The calling operation went from a linear cost model — more orders, more callers, more cost — to a fixed infrastructure model. The AI scales with order volume at marginal infrastructure cost, not marginal headcount cost.
