Direct answer
There's no single honest number — it depends on inquiry volume, how much a missed or slow-answered inquiry actually costs you, and what a human-only setup already costs (salary, hours covered, overtime for after-hours coverage). AI Sales Manager starts at €490/month plus a one-time setup fee; a Revenue Audit turns the framework below into a real comparison for your specific volume.
The cost of a human-only setup
Salary or hourly cost for whoever currently answers inquiries, plus the real gap in coverage — nights, weekends, lunch breaks, sick days — during which inquiries simply wait. Extending coverage with additional staff or shifts has a real, usually significant, cost that's easy to underestimate because it's spread across payroll rather than shown as a single line item.
The cost of AI response
A fixed monthly cost (from €490/mo for AI Sales Manager) plus a one-time setup fee that varies with channel count and qualification complexity — see AI Sales Manager Cost for the specific breakdown. Unlike additional staff hours, this cost doesn't scale with volume or coverage hours the same way — the same fee covers instant response at any hour.
The harder number: what a missed inquiry actually costs
This is the variable that actually decides the comparison, and it's specific to your business — average deal value, how often a slow response loses the inquiry to a competitor, and how many inquiries currently go unanswered or late. See Cost of Slow Lead Response for a worked framework on estimating this honestly, including the assumptions behind it.
Where human-only response still makes sense
At genuinely low inquiry volume, or where every conversation is highly bespoke with no common qualifying pattern, the fixed cost of AI response may not be justified yet — a human-only setup can be the right call, and that's said directly during a Revenue Audit rather than glossed over to make a sale.
The realistic answer, not the marketing one
AI response is usually cheaper than adding human coverage for after-hours and overflow volume specifically — it is not automatically cheaper than your existing staff for in-hours volume they already handle well. The honest comparison is about the coverage gap, not a blanket "AI beats humans on cost" claim.
Questions
Is AI Sales Manager cheaper than hiring another team member?+
Usually yes for extending coverage (after-hours, overflow) — not necessarily cheaper than staff already handling in-hours volume well. It depends on where your actual coverage gap is.
Does this replace our existing customer service team?+
No — see AI Sales Agent vs Human Sales Rep for the actual division: AI handles first response and qualification, humans handle judgement and closing.
How do I find the real number for my business?+
A Revenue Audit reviews your actual inquiry volume and current response gaps and turns this framework into a specific number, not a generic estimate.
