The number of purchased respondents credits can be spread over as many questionnaires as you want. One respondent credit is the used when a questionnaire with fewer than 30 questions is validated by a respondent. The questionnaires whose number of questions is greater than 30 will use more respondents credits (1 respondent credit / 30 questions).

Example:
- One questionnaire of 26 questions is validated by 1 respondent: 1 credit respondent used
- One questionnaire of 54 questions is validated by 1 respondent: 2 credit respondent used
- One questionnaire of 65 questions is validated by 1 respondent: 3 credit respondent used
