    TL;DR

    Reduce support costs 40-60% by deploying AI agents for repetitive queries while keeping humans for complex ones. The savings come from three places: lower cost per conversation, higher first-contact resolution, and agents spending time on high-value interactions instead of password resets.

    Support costs are rising. Hiring is getting harder. Customer expectations are increasing. AI agents offer a path to significant cost reduction without the quality trade-offs of traditional automation.

    Blended cost drops from €12 to €4.29 at 65% AI resolution, a 64% saving.

    The maths behind 40-60% savings

    If your blended cost per human-handled conversation is €12 and AI handles 50% of volume at €0.15 per conversation, your blended cost drops to €6.08. That is a 49% reduction. Scale the AI resolution rate to 65% and it drops to €4.29, a 64% reduction.

    Where the savings come from

    Direct cost savings: fewer conversations requiring human agents. Indirect savings: reduced training costs (AI agents do not need onboarding), lower management overhead, and eliminated after-hours staffing for 24/7 coverage.

    Protecting quality

    Cost reduction without quality is just cost shifting: you save money but lose customers. Monitor resolution rate, CSAT, and repeat contact rate alongside cost metrics. If quality dips, adjust the AI's scope or improve its knowledge base.

    Reallocating savings

    The smartest brands do not just pocket the savings. They reinvest in their human team: better training, higher pay, more interesting work. When agents handle only complex, meaningful conversations, job satisfaction increases and turnover drops.

    Implementation timeline

    Month 1: Deploy AI on top 5 query types. Month 2-3: Expand scope based on performance data. Month 4-6: Optimise model routing for cost efficiency. By month 6, most brands have reached their target cost reduction while maintaining or improving CSAT.

    The goal is not cheaper support. It is smarter support that happens to cost less.
