Where the numbers come from.
01
Cost per call
ContactBabel's UK contact-centre studies put a typical inbound call at £5.58-£6.26 (2023-24, 225 UK organisations surveyed).
02
Self-service deflection
Well-designed self-service handles 30-60% of routine contacts; every deflected call is money your team keeps.
03
Retention economics
HBR/Bain: acquiring a customer costs 5-25× more than retaining one, and apps roughly double repeat rates.
These are industry averages, not guarantees. We validate every assumption against your real numbers during discovery.
