Why good salespeople leave — and what they said beforehand

The short answer

A good salesperson does not resign on the day he resigns. He resigns months earlier, in subordinate clauses that get taken for grumbling — about the territory, about the statement, about the back office. By the time the letter is on the table the decision is old and the conversation about it is too late; what still helps then is money, and money holds nobody who has already left inwardly. Anyone who wants to reduce attrition in sales therefore needs no retention programme but two things: a regular conversation with no particular occasion, and the willingness to change something afterwards. And in case someone leaves anyway, three rules from the HGB and BGB that most sales managements have wrong in their heads.

The market is tight, the bond is thin

The most robust figures on this come not from sales but from the economy as a whole. For the Engagement Index Deutschland 2025 (surveyed 17 November to 20 December 2025, published in March 2026) Gallup reports: 10 per cent of employees have a strong emotional bond with their employer, 77 per cent a weak one, 13 per cent none at all. 12 per cent are actively job-hunting, 25 per cent are open to a change.

For context: in sales this bites harder, because good salespeople rarely have to search — they get found. On top of that comes a home-made factor. In its State of Sales study 2026 Salesforce puts the share of non-selling time at around 70 per cent (vendor study, to be read as an order of magnitude). Anyone who hired someone because he likes selling and then gives him three out of five days of administration has built the reason for resignation himself.

The five sentences said before the resignation

In teams I have built or taken over, the announcements almost always came in the same wrapping. Illustrative wordings, not quotes from real employees:

“Can you explain to me how this month's statement came about?”

That is not an arithmetic question. Trust in the commission is gone, and with it the reason to make an effort. Response: go through it together line by line, correct it if in doubt — do not make him explain it.

“I do the appointments, but nothing comes of them any more.”

The territory is empty or badly cut. That is not a motivation topic but arithmetic work for the manager.

“Just tell me what you want.”

The most expensive sentence of all. Someone has stopped making his own decisions. From here on you are not losing revenue, you are losing a salesperson.

“The new guy got my best account.”

Territory changes without explanation are regarded as expropriation, and anyone who feels expropriated stops building anything.

“That's just how long it takes here.”

Resignation in the face of your own processes. Incidentally, the customer hears this sentence too.

What a departure costs — a model calculation

Freely chosen assumptions, not a survey; replace the values with your own. The reference unit is one month's output, i.e. the average contribution margin the role brings in a settled state.

Item	Assumption	Cost in monthly outputs
Vacancy until the role is filled	3 months	3.0
Ramp-up time of the successor	6 months at an average of half output	3.0
Search, selection, management time	advertisements, interviews, possibly a recruitment consultancy	1.0–3.0
Risk to the book of business	customers with no contact person during the transition	not calculable, but real
Total		around 7 to 9

With ten salespeople and two departures a year that is 14 to 18 monthly outputs, a good full year's output that never shows up in any sales report — because it stays invisible as lost revenue while every pay rise is visible. That is precisely why the savings are made in the wrong place.

The stay interview: four questions, one meeting, no occasion

An exit interview is archive work. The same conversation twelve months earlier has an effect — twice a year, 45 minutes, with no numbers on the table, not in the pipeline meeting:

1. “What held you up the most in the last three months?”
2. “If you had my job: what would you abolish first?”
3. “Where do you want to be in two years — and what is missing for that here?”
4. “If a competitor calls you tomorrow: what would he have to offer for you to listen?”

The fourth question is the uncomfortable one and the only one that really gets something out. One rule goes with it: every conversation is followed within 14 days by exactly one visible change — or by none, and that is explained. A stay interview without consequences accelerates the departure instead of preventing it, because it proves that listening leads nowhere.

If he leaves anyway: three rules that then apply

Commission runs on. For employed salespeople § 65 HGB refers to § 87 (1) and (3) as well as §§ 87a to 87c HGB. Under § 87 (3) HGB the claim also exists for deals that only come about after the departure — if the departing person brokered them or initiated them in such a way that the close is predominantly attributable to his activity and occurs within a reasonable period after termination, or if the customer's offer had already been received beforehand. Anyone who cancels that commission saves once and pays permanently — through his reputation in the market.

The non-compete costs money. § 74 (1) HGB requires the written form and the handing over of a document signed by the employer. Subsection 2 makes the prohibition binding only if compensation of at least half of the contractual benefits last received is promised for each year. § 74a HGB limits it to a maximum of two years and to the protection of legitimate business interests. A clause in the standard contract without compensation for the restraint period is not protection but an illusion.

The notice period is shorter than people think. § 622 (1) BGB: four weeks to the fifteenth or to the end of the month. The longer graduated periods in subsection 2 apply to termination by the employer; under subsection 6 no longer period may be agreed for the employee than for the employer. In practice what often remains is four weeks for a handover that nobody prepared for.

Action list

1. Two stay interviews a year fixed in the calendar, separate from the pipeline meeting, with the four questions above.
2. One visible change out of every conversation within 14 days — or a reasoned refusal.
3. Make the commission statement recalculable: anyone who cannot follow his own statement distrusts it.
4. Justify and limit territory changes: no account is reassigned without a conversation, no territory is reduced without replacement potential.
5. Measure non-selling time and cut one task entirely once a quarter, instead of digitising it.
6. Check the contract documents: if there is a non-compete in there, is the compensation for the restraint period in there too? If not, the clause is worthless — better to delete it than to rely on it.
7. Treat the handover as the last act of selling: joint customer calls instead of a silent switch-off. A salesperson who is seen off properly will recommend people to you later. One who is seen off badly takes customers with him.
