Case Study
QVASAR

Advanced AI Integration:
9 Agents for Logistics & Distribution

Enterprise-grade AI deployment across 9 departments, freeing 525+ hours per month and achieving full payback in 4 months.

Sector: Logistics & Distribution  |  Size: ~120 Employees  |  Duration: 20 Weeks

01 — Executive Summary

Transforming a 120-person logistics company with intelligent automation

A mid-size logistics and distribution company operating from two warehouses in the Catalonia-Aragon corridor was drowning in manual processes. Sales reps spent hours on data entry, support teams fielded 800 tickets per month (60% repetitive), invoices were matched by hand with a 4-6% error rate, and management decisions were based on week-old Excel reports.

QVASAR deployed 9 AI agents across every operational department in a phased 20-week rollout. The result: 525+ hours of manual work freed per month, the equivalent of 3.5 full-time employees, with a total payback period of just 4 months and a Year 1 ROI of approximately 200%.

Core Pain Points

Manual processes saturated every department: sales lead entry by hand, customer support via phone only, paper-based HR forms, invoice matching done manually with 4-6% error rates, logistics tracking through spreadsheets, and zero unified reporting. Growth was stalling not from lack of demand, but from operational friction.

03 — Problem Analysis

Five systemic bottlenecks choking operational capacity

  1. Sales bottleneck: Leads arrived from the website, email, and trade fairs. Sales reps spent 2+ hours per day on data entry and manual CRM updates instead of closing deals. Lead scoring was gut-feel only — every lead received equal attention regardless of fit or intent.
  2. Support overload: Three support agents handled approximately 800 tickets per month. 60% of those tickets were repetitive queries (tracking updates, delivery ETAs, invoice status). Average first-response time sat at 12 minutes, and customer complaints about slow responses were increasing.
  3. HR administration burden: Leave requests via email (frequently lost or delayed), policy questions answered ad-hoc interrupting the HR manager 10+ times daily, and onboarding checklists on paper with a 30% incompletion rate. The HR manager spent 40% of their time on routine admin instead of strategic work.
  4. Invoice chaos: 1,200+ invoices per month processed entirely by hand. Invoice-to-PO matching consumed 3 FTE-days per week. A 4-6% error rate led to payment delays and supplier friction, eroding business relationships.
  5. No operational visibility: Reports were compiled manually in Excel every Friday afternoon. KPIs were always 5-7 days stale. Management was making decisions based on outdated data, with no real-time understanding of operational performance.

04 — Solution Architecture

06 — Per-Agent Breakdown

Nine agents, nine operational domains, one unified system

01

Sales Agent

Lead Scoring & CRM Sync
Problem

Sales reps spent 80-120 hours per month on manual lead entry and follow-up scheduling. No scoring system existed — every lead received equal attention regardless of fit or intent.

Solution

AI agent monitors inbound channels (web forms, email, trade fair scans), enriches lead data, scores on fit + intent, auto-updates CRM, and triggers follow-up sequences for high-score leads.

n8n workflows GPT-4o-mini CRM API Email parsing
