# How to respond to a customer questionnaire or a CSR questionnaire?
Responding to a customer questionnaire or a CSR questionnaire follows the mechanics of a tender: read every requirement, answer it with dated evidence, cite the source.
## What is a customer questionnaire and a CSR questionnaire?
A customer questionnaire is a list of questions a customer or contracting party sends a supplier to check its practices before or during a business relationship. A CSR (corporate social responsibility) questionnaire is a variant focused on social, environmental, and ethical practices, often tied to the sender's own non-financial reporting. Both share the same need: getting proven answers, not statements of intent.
These questionnaires resemble a tender in their structure: a series of requirements each calling for an anchored answer. They differ in the stakes, which are not winning a contract but remaining an approved supplier.
## How do you respond to a customer or CSR questionnaire, step by step?
Responding to a customer or CSR questionnaire follows the same order as a tender: understand each requirement, answer it with evidence, verify, validate. The difference lies in the material used: a CSR questionnaire draws on social and environmental policies, a customer questionnaire on operational and contractual practices. The method remains reading requirement by requirement, never filling in as you go.
| Type of questionnaire | What it asks you to prove | Where to find the evidence |
|---|---|---|
| **Customer questionnaire** | your operational and contractual practices | contracts, procedures, certificates |
| **CSR questionnaire** | your social and environmental commitments | CSR policies, reports, charters |
| **Security questionnaire** | your data-protection practices | security policies, audits |
## Does a single library of answers serve several types of questionnaires?
A single library of answers serves several types of questionnaires because requirements overlap from one family to another. An answer on data protection serves a security questionnaire as well as a customer questionnaire; an answer on working conditions serves a CSR questionnaire as well as a supplier audit. Building a single library avoids rewriting, for every new format, an answer already validated elsewhere.
On the Optivalue.ai platform, which publishes this site, these families are handled under five use cases: tenders, security questionnaires, customer questionnaires, non-financial reporting, and supplier analysis, served by the same library of answers.
## The concession that clarifies everything
For a short customer questionnaire, received once, on a subject you know well, a hand-written answer is enough with no tooling. A tooled method makes sense once questionnaires multiply, the same requirements come back from one customer to the next, and consistency across answers becomes an issue in itself. The dividing line is repetition: it is what turns a one-off exercise into a recurring workload.
## Points to watch on a CSR questionnaire
1. **Evidence over intention**: a stated policy is not worth as much as an attested practice.
2. **Consistency over time**: a reused CSR answer must reflect the commitments currently in force.
3. **A declared scope**: specifying what a practice covers avoids an overly broad claim.
4. **The supplier chain**: corporate due-diligence duties, under the law applicable in each market, cover, for companies subject to them, risks linked to their own activity and to that of their partners.
5. **Human validation**: a public CSR commitment binds the company and needs a signature.
## Frequently asked questions
**Is a customer questionnaire handled like a tender?**
A customer questionnaire is handled with the same method as a tender, requirement by requirement with evidence, but its stakes are keeping a relationship, not winning a new contract.
**Can you reuse CSR answers from one year to the next?**
You can reuse CSR answers if they remain true: a commitment changes, a practice evolves, and a dated answer flagged for review avoids asserting an outdated state.
**Does a CSR questionnaire belong to the same library as security questionnaires?**
Yes: both draw on the company's proven knowledge, and a single library avoids rewriting an answer already validated for another format.
**Who should validate answers to a CSR questionnaire?**
Answers that commit the company on its social or environmental practices call for human validation, because they are statements that can be held against the supplier.
