Discover how an AI voice agent for e-commerce logistics automated the resolution of inventory holds for a supplement and cosmetic e-commerce business. In 20 operational weeks, DeepAgent's AI voice agent "Giulia" managed 18,364 outbound calls, completed 4,765 conversations, and maintained 7-day-a-week coverage. The cost per positive resolution dropped to €3.49, and the average cost per conversation to €1.13. Here's the process, KPIs, and replicable learnings for other logistics operators. ## TL;DR - 18,364 outbound calls in 20 weeks, 7/7 coverage from 8:00 AM to 6:00 PM. - 4,765 completed conversations, average completion rate 25.95%. - 1,549 positive outcomes: one valid resolution/instruction every ~3 real conversations. - Cost per positive resolution €3.49, cost per completed conversation €1.13. - Recall up to 6 attempts/day: 35.8% of contacts reached after the first attempt. - CRM integration via API with real-time outcome writing. ## The Client and Context Our client is an anonymous Italian integrated logistics operator that manages customer care and inventory hold resolution for an e-commerce business selling supplements and cosmetics. Each case requires a decision from the recipient: new delivery or return. Without a decision, the package remains in storage, incurring daily costs. The sector faces three pressures: increasing volumes with declining per-package margins, immediate response expectations from end customers, and human teams that don't scale (especially on weekends).  ## The Situation Before AI: Unmanageable Volume - 10,000–15,000 inventory holds/month to resolve. - 500–800 calls/day during peaks, never fully covered. - Inconsistent conversation quality and CRM updated manually, leading to errors/delays. - No weekend coverage: backlog and storage costs accumulated. ## The Operational Funnel: From Hold to Resolution 1. **Import of the hold case.** The CRM sends a complete context via API: recipient, address, order/product, courier, reason for failed delivery, cash on delivery (COD) status. 2. **Prioritization and outbound sequence.** An active queue 7/7 (8:00 AM–6:00 PM) to anticipate costs and minimize returns. 3. **Attempts and recall.** Up to **6 attempts on the same day**, optimized timings, and rotating caller ID every 3–4 days. 35.8% of contacts are reached beyond the first attempt. 4. **Identification and context.** Verifying the interlocutor and reason: shipment on hold requiring operational instructions. 5. **Decision collection.** Confirming/updating redelivery conditions, requesting a return, or reporting an anomaly. Objective: a viable decision. 6. **Exception handling.** Unresolvable cases (address issues, unavailability, disputes, COD issues, ambiguous instructions) forwarded to the human team with full context. 7. **Classification and CRM update.** Outcome written in real-time via API: positive, to be reattempted, or exception for manual processing. 8. **Closure or new action.** Positive outcomes sent to the courier; unreached cases remain in recall; complex cases pass to the team. The resolution counts, not just the call.  ## The 4-Phase Implementation - **Phase 1 — Planning.** Workflow mapping, requirements (500–800 calls/day, 7/7, 8:00 AM–6:00 PM) and API integration for writing outcomes to CRM. - **Phase 2 — Configuration and training.** Specific conversational script for logistics. Each call receives a JSON payload with key fields. Professional voice, direct tone. - **Phase 3 — Testing and validation.** Pilot on a sample, calibration of time slots and recall (up to 6 attempts/day), caller ID rotation. - **Phase 4 — Go-live and scaling.** Full activation, live monitoring, and continuous optimization of scripts and outcome criteria. ### Challenges Addressed - **Outcome classification.** Clear definitions between valid resolutions and contacts without a decision unlocked a **79.6% success rate** in the best week. - **Voice infrastructure.** A peak saw **783 calls blocked** upstream by the switchboard, outside the DeepAgent perimeter. ## The Results: 20 Weeks of Real Data ### Volumes and Performance - **18,364** outbound calls managed autonomously. - **4,765** completed conversations, totaling **10,803** minutes (**180 hours**). - Average completion rate **25.95%**. - Average duration per completed conversation **2.27 minutes**. - **1,549** positive outcomes: **32.5%** of completed conversations, **8.4%** of total attempts. - Maximum weekly success rate **79.6%**. ### Monthly Trend | Period | Calls | |---|---| | Month 1 | 1,214 | | Month 2 | 4,202 | | Month 3 | 2,716 | | Month 4 — seasonal peak | 9,208 | | Month 5 (partial) | 1,024 | | **Total** | **18,364** | The peak month accounts for about half of the total volume: this is the scenario where human teams saturate, while the agent's capacity remains constant. ### Key KPIs | KPI | Value | |---|---| | Total outbound calls | 18,364 | | Completed conversations | 4,765 | | Average completion rate | 25.95% | | Conversation minutes | 10,803 (180 hours) | | Average conversation duration | 2.27 min | | Positive outcomes (resolutions/valid instructions) | 1,549 | | Positive outcomes from completed conversations | 32.5% | | Maximum weekly success rate | 79.6% | | Cost per completed conversation | €1.13 | | Cost per positive resolution | €3.49 |  ## The ROI, Clearly Calculated The agent's cost is linear: **10,803 minutes × €0.50/min = €5,401**. From this, two key metrics: - **€1.13 per completed conversation**: cost to actually speak with the recipient. - **€3.49 per positive resolution**: cost to obtain a usable operational decision. The second is what truly matters for logistics: without a decision, the package remains stalled. ### Comparison with Human Management | Item | Calculation | Hours | |---|---|---| | Effective conversations | 10,803 minutes | 180 | | Unanswered attempts | 13,599 attempts × 45 sec | 170 | | CRM updates | 4,765 conversations × 45 sec | 60 | | **Total** | | **≈ 410 hours** | With a fully loaded hourly cost of **€20–€25/hour**, the human equivalent would be worth **€8,200–€10,250**, compared to the agent's €5,401: a **saving of 34–47% (≈41%)**. This is a conservative estimate: it doesn't include training, turnover, or weekend surcharges. ## The Value of Automatic Recall Out of a sample of **2,315** leads, **64.2%** were reached on the first attempt; **35.8%** only thanks to subsequent recalls. In other words: over a third of conversations exist because the system consistently attempts recalls up to 6 times on the same day. This persistence, for hundreds of cases daily, cannot be replicated manually.  ## Benefits Beyond the Numbers - **For the end customer:** quick contact, short and conclusive conversation, 7/7 coverage (including weekends). - **For the logistics team:** 500–800 routine calls per day eliminated, focus on complex cases, CRM automatically updated. - **For the company:** scalability during peaks without seasonal hires, consistent performance, end-to-end traceability. ## Lessons Learned ### Why it Works in Inventory Hold Management - **High volume, low variability.** Repeatable conversational structure, only the case content changes. - **Complete context via JSON.** No preliminary data collection: shorter calls and fewer abandonments. - **Structural recall.** Up to 6 attempts/day account for +35.8% recovered contacts. - **Continuous optimization.** Scripts, timings, and outcome criteria are refined after go-live. ### Mistakes to Avoid - Poorly defined outcome criteria: unusable data. - Neglecting weekend coverage, where backlog accumulates. - Generic scripts not tailored to logistics. - Considering go-live as the finish line, not the start of improvement. ## Where Inventory Hold Management is Heading From automation to predictive: prioritization by resolution probability, dynamic scripts based on recipient history, omnichannel orchestration (voice, SMS, WhatsApp), and optimal time scoring for each attempt. ## Conclusion Automating a high-volume, low-variability process frees up capacity and reduces costs: 18,364 calls managed, 4,765 real conversations, and 1,549 resolutions at €3.49 each, with 7/7 coverage.

An AI voice agent integrates with the CRM via API, receives case details (recipient, order, courier, hold reason, cash on delivery status), and initiates outbound call sequences 7/7. It identifies the interlocutor, collects a decision (redelivery or return), classifies the outcome, and updates the CRM in real-time. Exceptions are forwarded to the human team. This is a streamlined flow optimized for e-commerce inventory hold management. ### What integrations are necessary for outbound call automation in logistics? An API integration with the CRM/management system is sufficient to send case payloads and receive outcomes. Optional integrations include telephony systems and couriers to automate redelivery. The AI voice agent writes outcomes in real-time and supports fields like cash on delivery, failed delivery reasons, and operational notes. ### What results can I expect in terms of KPIs and costs? Benchmark results from this case: 25.95% completed conversations, average duration 2.27 minutes, 32.5% positive outcomes from completed conversations, and €3.49 per valid resolution. The cost per conversation is €1.13. With high volumes, the agent maintains constant performance and 7/7 coverage, reducing backlog and storage costs. ### What is the ROI compared to a human team in logistics customer care? Within the measured scope: 10,803 minutes of conversations, 13,599 unanswered attempts, and 4,765 CRM updates. The human equivalent would require ≈410 hours. At €20–€25/hour, the estimated cost is €8,200–€10,250, compared to the agent's €5,401: a saving of 34–47%, with additional benefits in continuity (7/7) and scalability during peaks. ### How does it handle exceptions, cash on delivery, and ambiguous cases? Exceptions are classified and forwarded with complete context: address correction, prolonged unavailability, disputes, doubts about cash on delivery, or unclear instructions. The AI voice agent avoids loops, collects operational notes, and assigns the case to the human team, preserving KPIs for automated inventory hold resolution. ### Is it compliant with data privacy and security? Yes. API integration limits the data processed to what is strictly necessary for inventory hold management. Conversations are processed according to minimization policies, with outcome auditing on the CRM. Masking for sensitive data (e.g., cash on delivery) and role-based access controls can be activated.
