EmpfangoWhat does a missed call cost? Calculator for site manager phone time
Site managers in commercial cleaning spend every morning on the phone with sick calls, queries and complaints. This calculator shows how many hours a month that adds up to, what it costs and whether automated first-line intake from €99 per month pays off.

Why a site manager's phone time is expensive
A missed call costs either a job or a staffed shift. According to time-tracking vendor clockin, “every third call in small businesses goes unanswered” (clockin, as of 10/2026). In building services that means: a sick call lands on voicemail, the site stays unstaffed in the morning and the client rings with a complaint. The calculator above therefore does not price the missed call itself but the time the site manager spends today so that as little as possible is missed.
The phone load is documented. Software vendor Blink describes the typical start of the day in its site manager blog: “Especially in the early morning hours it means: find a replacement, reshuffle shifts or step in yourself. Site managers often start their day with several phone calls.” Sickness absence in commercial cleaning stood at 29.1 calendar days per employee in Bavaria in 2023, the highest of all occupational groups; 71.3 % of companies reported rising absence since phone-based sick notes were introduced, according to the BIV autumn survey 2024 (bkv Firmenservice, as of 10/2026). The industry's labour cost share is 85 % according to the BIV industry report 2025; every office hour hits the margin directly.
The hourly rate is the lever you know best. As a benchmark, jobvector quotes an average salary for site managers of €41,460 gross per year, around €3,455 per month, with a range from €35,316 to €49,752 (jobvector, Objektleiter salary 2026, as of 10/2026). Adding employer contributions of roughly 20 % and dividing by 168 hours gives about €25 per hour. Enter your own full-cost rate if it differs; for owners who answer the phone themselves, the opportunity value is usually higher.
A worked example: 15 calls a day at 4 minutes each over 21 working days make 1,260 minutes, or 21 hours a month. At €25 per hour that is €525 in staff costs for first-line intake alone. The smallest plan whose included minutes cover that volume costs €249 per month; the calculated difference is €276. The minutes are counted generously: Empfango only needs the talk time for a sick call, and the follow-up disappears because name, site, shift and duration already reach the site manager in structured form via WhatsApp, Telegram or email.
What the calculator does not show: the calls after 5 p.m. and at weekends that nobody answers today, and the value of a documented report with transcript and summary. How a sick call is recorded by phone, what the site manager does in the company and how cleaning companies use Empfango is shown on the page AI phone assistant for cleaning companies. All plans with included minutes are on the pricing page.
Frequently asked questions about the calculator
It depends on the caller. A missed sick call costs an unstaffed shift and often a complaint; a missed quote request costs a potential job. The calculator therefore starts from the measurable quantity: the time the site manager currently spends on first-line call intake, valued at your hourly rate.
A month has around 21 weekdays from Monday to Friday on average. If you also take calls on Saturdays or in shift operation, set the calls per day higher accordingly; the assumption stays fixed so that results remain comparable.
Calls per day and minutes per call give the monthly minute volume. The suggestion is the smallest plan whose included minutes cover that volume: 1,000, 2,500 or 5,000 minutes. Above that we recommend the Verbund plan with unlimited talk time. All plans are fixed prices with no overage.
Then the pure staff cost for first-line intake is below the plan price. In that case other reasons decide: reachability outside office hours, documented reports with transcript, no voicemail for clients and prospects. These effects cannot be converted into euros credibly, so the calculator leaves them out.
No. Empfango answers calls, records sick calls, complaints and enquiries in a structured way and reports them via WhatsApp, Telegram, email or webhook. Rescheduling, finding cover and client conversations stay with the site manager. The calculator only values the first-line intake, not the work after it.
