# Surveys: NPS and feedback calls that ask why.

The agent asks your questions in order, follows up when an answer is vague and returns the same structured fields from each call. Use it for NPS, satisfaction, product feedback or a check-in after a visit.

Fits: Retail and e-commerce, Service businesses, Contact centers, Market research.

## One call, start to finish

*An example NPS call*

> **Agent:** Hi, this is Leo, an AI assistant from the store. You picked up an order on Saturday. May I ask two quick questions about it?
> **Caller:** Okay, quickly.
> **Agent:** From 0 to 10, how likely are you to recommend us to a friend?
> **Caller:** Hmm, a seven, maybe.
> **Agent:** Thank you. What would have made it a nine or a ten?
> **Caller:** The pickup took forever. Twenty minutes, at least.
> **Agent:** Sorry about that, I’ll pass it on. Was everything in the order correct?
> **Caller:** Yes, all fine.
> _↳ Saves the answers to your survey table_
> **Agent:** That’s all. Thanks for your time, and have a good day!

One row per call:

```json
{
  "completed": true,
  "nps": 7,
  "reason": "Pickup wait of about 20 minutes",
  "order_correct": true,
  "call_back": false
}
```

Surveys rarely need a person. The agent still transfers a caller who asks for one or raises a complaint.

## How it works

1. **Write the questionnaire.** Questions in plain language, with the follow-ups: “if the score is below nine, ask why”.
2. **Choose who and when.** Contact lists and calling hours run as campaigns through Incoplax telephony.
3. **Rehearse.** Run simulated conversations with scripted callers before the first real call.
4. **Collect.** Every call returns the same fields, ready for a spreadsheet, a dashboard or your CRM.

## What the agent handles

- **Keeps your order of questions.** Your questions in sequence, in a conversation rather than an IVR menu.
- **Follows up on vague answers.** When someone says “it was okay”, the agent asks what would have made it better.
- **Respects “not now”.** Notes a better time, or ends the call politely when the person would rather not answer.
- **Lets people interrupt.** Callers can talk over the agent; it stops and listens.

## Good to know

- A maximum call duration keeps surveys short and ends them politely.
- Free-text answers are summarized; the full transcript stays in the journal.
- The greeting can announce the AI and the recording.
