A missed call rarely costs you just that one conversation: behind calls there are often buying intentions, appointment requests, or urgent matters – and whoever can't get through often calls the next provider. The tricky part: missed calls leave no trace. The lost order doesn't show up in any report, because it never happened.

## The invisible source of loss

You usually know the least about the weaknesses in your own telephone process. An unanswered email stays in the inbox and serves as a reminder. A missed call is simply gone – at best as a number in the call list, at worst unnoticed, because the line was busy. On top of this comes the second, quieter damage: those who repeatedly can't reach anyone draw conclusions about the reliability of the business as a whole.

## Calculate it for your business

Made-up average figures won't help you – your own will. You need four values that you can estimate or count over the course of a week:

1. **Missed calls per week** – check the call list: count unanswered calls and busy attempts.
2. **Share of new inquiries** – how many calls typically come from prospects rather than existing customers?
3. **Your closing rate** – how many inquiries usually turn into an order for you?
4. **Average order value** – what is an order worth for you on average?

Multiply the four values, and you have a conservative estimate of the lost revenue per week. For businesses with recurring customers, you may use the customer value over the years instead of the single order – then the figure usually becomes uncomfortable. And it is deliberately conservative: follow-up orders, referrals, and the quiet reputational damage from repeated unavailability come on top.

## Where calls are typically lost

- **Peak times:** All lines or hands occupied – precisely when demand is highest.
- **Outside business hours:** Many customers call when they themselves are off work.
- **Understaffing:** Vacation, illness, an appointment – in a small team, one absence is enough.
- **The answering machine effect:** Experience shows that many callers don't leave a message, especially on first contact – the recorded message doesn't replace the conversation.

## Stopping the loss: incoming calls get answered

The most effective countermeasure is banal: answer calls – including in parallel, including at 9 p.m. That is exactly what AI call answering does: an AI assistant takes the call immediately, answers questions from your stored knowledge, records the matter along with a callback number, and forwards urgent cases to a human according to your rules. Your team then finds a summary in the log and calls back prepared. How this works in detail is explained in the article [AI call answering](/en/wissen/ki-anrufannahme.html).

## The practical test

With [webRichtung phone](https://www.webrichtung.de/module/phone/) you can test the principle with little risk: set up Phone Agent with its own phone number, redirect your company number there when busy or after hours – and after a week, check the call log to see what would otherwise have been lost. 15 call minutes in 7 days are free; after that you pay per use. The log entries are, by the way, your first reliable statistics on what was previously invisible.
