What do you ask a client after a project ends?

Ten questions on one page, sent within five working days of sign-off. The core four: was the agreed goal achieved from your point of view, what was the most important result for you, how much effort did you have to put in to keep the project running, and would you commission us again for something comparable. The effort question is the best early warning signal for non-renewal in service businesses, and the re-commission question is a far more reliable loyalty measure than NPS when you only have a few dozen clients. Ask the rest — quality, deadlines, budget, reachability, communication — as 1-to-5 ratings so you can compare across projects.

Does ISO 9001 require a customer satisfaction survey?

No — and this is the most widely misunderstood point in the standard. Clause 9.1.2 requires you to monitor customers' perception of the degree to which their needs and expectations have been fulfilled, and to determine the methods for obtaining, monitoring and reviewing that information. It requires *that* you do something and that the method is defined; it does not prescribe a questionnaire. The note to the clause explicitly lists other valid sources: customer feedback on delivered products and services, meetings with customers, market share analysis, compliments, warranty claims and dealer reports. For a consultancy with fifteen clients, documented project debrief conversations are fully compliant — and usually more informative than a survey nobody fills in.

Why is NPS a bad metric with few clients?

Because a single person moves it by 200 divided by your sample size. At 20 responses, one client shifting from promoter to detractor swings the score by 10 points; at 10 responses, by 20 points. Worked example: 15 answers with 12 promoters, 2 passives and 1 detractor gives an NPS of +73 — but the standard error is about 15 points, so the 95 percent confidence interval runs roughly from 44 to 100. Measuring 61 the following year is not a downward trend, it is one client who had a bad quarter. Comparing that number to a published industry benchmark, which is typically computed on thousands of responses, is mathematically meaningless. Use absolute measures instead: re-commission rate, share of clients with documented feedback, open actions arising from feedback, and a named traffic light per account.

Should B2B feedback be anonymous?

No, and pretending otherwise is a mistake. With twenty clients, anonymity is transparent anyway — everyone knows who said what. More importantly, the point of B2B feedback is not to compute a population average but to act on *this* account: you want to know that the manufacturing client is unhappy with response times so you can call them on Monday. Attributable, account-based feedback is what makes that possible. Where anonymity genuinely helps is when the feedback concerns a specific person on your team, because a client will not criticise a consultant by name to that consultant's employer.

When do you ask a client why they cancelled?

After the cancellation has been given, but before the contract actually ends — roughly one to two weeks after. At that point the relationship still exists, the memory is fresh, and the pressure is gone. During the negotiation you are not conducting an interview, you are attempting a save, and the answers will be tactical. After the contract ends, people stop replying. Two rules make the difference between a useful conversation and a polite one: the responsible account manager must not run it, and you have to say out loud that you are not trying to win them back. Keep any recovery attempt as a separate conversation three to six months later.

B2B Customer Satisfaction Questionnaire: 3 Templates

Why B2B Feedback Is a Different Job

Short answer: almost every German template you will find asks about delivery, product quality and repurchase — because it was written for a webshop. A nine-month consulting engagement cannot be evaluated with "wie zufrieden waren Sie mit Ihrem Kauf". Four differences change the instrument entirely.

The respondent is not the decider. B2B buying groups typically involve six to ten people. The project manager who answers your questionnaire is usually not the person who signs the renewal — which is why a green operational score alongside a silent managing director is the classic surprise churn. Survey at least two roles per account.
Relationship, not transaction. Satisfaction accumulates over months of joint work rather than attaching to one purchase moment.
Low N breaks the statistics. You have twenty to two hundred clients, not twenty thousand. Significance tests, trend lines and benchmark comparisons stop working — see the NPS section below.
Missing one account is a gap, not noise. Response rates run higher than B2C, commonly 15 to 30 percent, but the sample is fixed — you cannot buy more of it. One key account that does not answer is a hole in your data, not sampling error.

1. After Project Completion: 10 Questions

One page, sent within five working days of sign-off. This is the set that also satisfies the ISO 9001 evidence requirement, because question 1 asks directly about fulfilment of requirements.

Question	Scale	What it decides
Was the agreed goal achieved from your point of view?	yes / partly / no + open	The ISO 9.1.2 core question
What was the most important result of this project for you?	open	Your value wording for proposals and case studies
How do you rate the professional quality of the results?	1-5	Staffing and skills development
How do you rate adherence to deadlines and budget?	1-5 each	Estimation quality, project control
How do you rate reachability and response time of your contact?	1-5	Almost always tops the complaint list
How much effort did YOU have to put in to keep the project running?	very low - very high	The best early warning for non-renewal
What should we have done differently, and at exactly which point?	open	The concrete improvement action (ISO clause 10)
Is anything left open from the project?	open	Immediate escalation plus follow-up business
Would you commission us again for a comparable project?	yes / maybe / no + why	The only robust loyalty proxy at low N

2. Annual Review: Ask Two Roles, Then Read the Gap

Send the operational questions to the person you work with daily, and the strategic ones to whoever controls the budget. The result is not the average of the two — the result is the difference between them. An operations contact who is delighted and a managing director who cannot name what you contributed is the most reliable churn signal in B2B, and a single averaged score hides it completely.

Question	Ask whom
How satisfied are you with the collaboration over the past year overall?	all roles
How well does our team understand your business and industry?	specialist + management
How easy are we to work with — proposals, coordination, invoicing?	purchasing / operations
Where did we contribute most to your goals last year?	management
Which of your topics for the next 12 months do we not know about yet?	management
How do we compare to your other service providers?	all roles
What would have to happen for you to expand the collaboration?	management
What would have to happen for you to end it?	management — the early warning question

3. The Cancellation Interview

This is a conversation, not a form, and it is the single most valuable feedback you will ever collect — because it is the only moment a client has no reason left to be polite. A dropdown list of cancellation reasons produces the socially convenient answer, which is almost always "price". Twenty to thirty minutes on the phone produces the real one.

When: one to two weeks after the cancellation, before the contract ends.
Who: not the responsible account manager. Management or a neutral person — otherwise you get politeness.
Say this first: we are not trying to win you back, we want to understand what we got wrong.
The five questions that matter: when did you first think about ending it; what was the concrete trigger; what was the actual reason behind that; was there a moment we could still have turned it around, and what would we have had to do; did you raise it before, and what happened then.
Recovery is a separate conversation three to six months later. Mixing the two turns the interview into a sales call and the answers into tactics.

Question three — "und was war der eigentliche Grund dahinter?" — is where the price excuse usually falls away. Ask it as a standard follow-up every time, even when the first answer sounds complete.

ISO 9001: What the Auditor Actually Wants

Clause 9.1.2 requires you to monitor customer perception of whether their needs and expectations were fulfilled, and to determine the methods for obtaining, monitoring and reviewing that information. It does not require a survey. What trips organisations up is that 9.1.2 does not stand alone — it chains into 9.1.3 (you must analyse and evaluate the data, customer satisfaction explicitly among it), 9.3.2 (customer satisfaction is a mandatory input to the management review) and clause 10 (improvement). Clause 8.2.1 separately covers handling customer feedback and complaints.

The most common finding in practice is not a missing survey — it is forms collected and nothing decided. Auditors ask for five things: the documented method (which channels, what cadence, who is responsible), evidence of collection with dates and coverage, evidence of analysis rather than a stack of raw forms, evidence of action with an owner, a deadline and an effectiveness check, and evidence that it reached the management review. Collecting alone is not enough — that sentence is worth putting on the wall.

Why NPS Fails Below 50 Clients — the Arithmetic

NPS is the percentage of promoters minus the percentage of detractors, which means it responds linearly to individual people. One respondent moving from promoter to detractor changes the score by 200 divided by n.

Responses (n)	One promoter becomes a detractor	One promoter becomes passive
10	20.0 points	10.0
15	13.3 points	6.7
20	10.0 points	5.0
50	4.0 points	2.0
2 000	0.1 points	0.05

Worked example. 15 answers: 12 promoters, 2 passives, 1 detractor. NPS = (12 − 1) / 15 = +73. The standard deviation of that distribution is about 0.573, so the standard error is 0.573 / √15 ≈ 0.148 — about 15 points. At 95 percent confidence your NPS of 73 is really somewhere between 44 and 100. Measuring 61 next year is not a trend; it is one client who had a bad quarter. And comparing it to a published benchmark computed on thousands of responses is comparing a coin flip to a weather forecast.

Two further problems make it worse in B2B: NPS throws away information by collapsing a 0-to-10 scale into three buckets, and it weights a 4,000-euro client exactly like a 400,000-euro one. If a parent company contractually requires an NPS, report it — but always with n and the confidence interval, and never as a trend line. For your own steering, use absolute measures: re-commission rate, share of clients with documented feedback, open actions from feedback, and a named traffic light per account. For the employee-side equivalent and why the two must never be averaged, see the eNPS guide.

Running It With teamo

The three question sets above work on paper, in an email, or in any survey tool. Two things are worth automating: the trigger, so the project-completion questionnaire actually goes out within five working days instead of whenever someone remembers, and the follow-up question, because a client who rates reachability a two and writes nothing has told you where the problem is but not what it is.

Describe the moment in chat

Tell teamo you want a project-completion interview for B2B clients with the ten questions above. It drafts it and you adjust the wording.

Use personalized invites, not an anonymous link

B2B feedback should be attributable — you want to know which account said what so you can act on Monday. Each contact gets their own link.

Send to two roles per account

Operational contact and budget owner get different question sets. The gap between their answers is the actual result.

Let low ratings trigger a follow-up

A two out of five on reachability gets a why-question immediately, while the client is still in the form. That is the answer you would otherwise have to phone for.

Export the evidence for the audit

Dates, coverage, answers and the actions you derived — that is the 9.1.2 to 9.3.2 chain in one place, which is what turns an audit conversation into a short one.
