The hidden costs
What no one puts in the budget line
These are the costs that don't show up on the offer letter — but they're real, recurring and they're why the headline salary is so misleading.
Attrition
UK customer support has ~30% annual turnover. Every leaver costs ~£4–6k in recruitment, onboarding and lost productivity.
Out-of-hours gaps
35% of tickets arrive outside 9–5. Either you pay for a night shift, miss them, or live with bad CSAT scores.
Management overhead
1 team lead per 5–6 agents at £40–55k fully-loaded — pure overhead the AI workforce doesn't need.
Tool sprawl
Zendesk, internal wiki, Slack, CRM, knowledge base — each agent needs a seat in 4–6 tools. £150–£300/mo per head.
The AI workforce alternative
