Voice AI for Last-Mile & 3PL Operations
Cut NDR, verify addresses and coordinate drivers in Hindi and 6+ regional languages — on your own SIP trunk at flat ₹1.5/min.
Indian last-mile logistics runs on phone calls — NDR confirmation, address clarification, delivery window negotiation, reverse pickup scheduling and driver coordination. Most of this volume sits in Hindi and a handful of regional languages, and most of it is repetitive. ThinnestAI lets 3PLs and D2C ops teams run fully automated voice agents over Twilio, Vobiz or self-hosted LiveKit SIP, with INR billing and GST invoices. You bring your WMS webhooks, we bring the language quality and the flat ₹1.5/min platform fee.
NDR rates in Indian ecommerce routinely sit between 25-40%, and most of that is fixable with a single clarifying call. Tele-calling teams are expensive, attrit fast and rarely speak the customer's actual language well enough to handle address landmarks. Static IVR trees get abandoned. Existing voice bots default to English or clunky Hindi and refuse to handle code-switching. Meanwhile operations heads are paying ₹4-8 per human call with poor connect rates and no structured data back into the WMS.
- Native Hindi and regional voice agents that handle landmark-based addresses and code-switched speech without falling back to English.
- Webhook integrations with Shiprocket, Unicommerce, EasyEcom and custom WMS for real-time AWB lookup and status push-back.
- BYOK SIP on Twilio, Vobiz or self-hosted LiveKit — use your own DIDs, your own DLT headers, your own call recordings.
- Structured outcome tagging (reattempt, reschedule, RTO, address updated) written back to your OMS via webhook.
- TRAI DLT-compliant call windows, opt-out handling and per-pincode throttling built into the flow editor.

Sample logistics call flow
How a real logistics voice agent actually runs on ThinnestAI — from pickup to wrap-up, with compliant disclosures baked in. Watch it play, or scroll to explore each step.
Greeting & identity check
Agent introduces itself, confirms the customer name and AWB context in the customer's preferred language.
Delivery intent confirmation
Agent asks whether the customer will be available and whether the address is still correct.
Address & landmark clarification
If the driver flagged an address issue, agent captures landmark, nearest shop or Google Maps pin over voice.
Reschedule or COD confirmation
Offers alternate slot, confirms COD amount, or accepts prepaid switch.
Driver handoff notification
Triggers SMS or WhatsApp to driver with updated address and slot via webhook.
Structured write-back
Posts outcome (reattempt / reschedule / RTO / address-updated) into OMS with transcript and recording URL.
Where logistics voice AI actually wins
NDR reattempt calls
Call every failed delivery within 30 minutes to confirm intent and reduce RTO by clarifying address or slot.
Address verification at order stage
Pre-ship verification call to flag bad addresses before dispatch, saving forward logistics cost.
COD confirmation for high-value orders
Confirm intent and amount for COD orders above a threshold, reducing fake-order RTO.
Reverse pickup scheduling
Coordinate returns and exchanges with slot selection and pickup executive handoff.
Driver coordination hotline
Inbound line where delivery partners can call to update hub, request reassignment or confirm POD in their language.
Hyperlocal dispatch alerts
Outbound calls to merchants and riders for Q-commerce order acknowledgement during peak windows.
Compliance, out of the box
Regulated workloads get regulated defaults. ThinnestAI enforces these on every agent for this industry — you can override with a compliance review, but the defaults are safe.
TRAI DLT
Header and content template registration supported; per-pincode calling-window throttles available.
DPDP Act 2023
Consent capture on first call, opt-out intent recognition and configurable retention for recordings and transcripts.
Call timing rules
Hard-enforced 09:00–20:00 IST calling window per TRAI UCC guidelines; overrideable only with documented consent.
Data residency
Self-host on Azure Central India or GCP Mumbai with your own LiveKit cluster for teams with sovereignty requirements.
The ROI math
| Option | Cost | Unit |
|---|---|---|
| In-house tele-calling team | ₹6–8 | per connected call |
| BPO outsourced NDR desk | ₹4–6 | per connected call |
| ThinnestAI voice agent | ₹3–4/min | all-in with cost-optimized stack — ~₹10–16 per 3–4 min call |
When ThinnestAI is NOT the right fit
Be honest before you buy. These are the logistics scenarios where voice AI — ours or anyone else's — is the wrong tool.
- —You need a full logistics OS with carrier APIs and tracking pages — ClickPost, eShipz and Shiprocket Engage are specialist tools and we complement them, not replace them.
- —Your NDR volume is under 5K calls/month — a well-trained tele-caller is cheaper and faster to set up.
- —You need hard real-time driver dispatch decisions — that belongs in your routing engine, not a conversational agent.
- —Customer disputes involving refund amounts or damaged goods — escalate to human CX, don't let the bot negotiate.

Frequently asked questions
Can ThinnestAI push NDR outcomes back into our Unicommerce / Shiprocket / custom WMS?
+
Yes. Every call ends with a structured outcome webhook you configure in the flow editor — reattempt, reschedule, RTO, address-updated — along with transcript and recording URL.
Do we have to use your SIP or can we bring Twilio / Vobiz?
+
BYOK SIP is the default. You bring your own Twilio subaccount, Vobiz numbers or plug into your own LiveKit cluster. We charge the flat ₹1.5/min platform fee on top of your telco cost.
How well does the Hindi agent handle landmark-based addresses?
+
The flow editor lets you prompt the agent to ask for specific landmark, nearest shop or pin location, and we transcribe the spoken address back into structured text. It's not perfect on very noisy lines but materially better than a static IVR.
Is this TRAI DLT compliant?
+
Yes. You register your headers and templates on your PE, and our flow editor enforces calling-window and opt-out rules. Recordings and consent are stored per DPDP Act retention policy.
Can drivers call in, not just receive outbound?
+
Yes — inbound flows are first-class. A common pattern is an inbound line drivers call to update hub status or confirm POD in Hindi or Marathi.
