Single choice questions vs. Multiple choice questions vs. Free text questions in an RFP

Asking your suppliers the right question is key in running a successful RFP. That’s why we’ve created 3 types of questions which can help you easily ‘extract’ all the valuable information from your suppliers in an efficient way: Free Text, Single Choice Questions and Multiple Choice Questions.


Bellow is a guide for building the right RFP questionnaire:

What is each type of question?

  • Free text question: Suppliers can provide any answer they choose without you forcing them to select from specific options. This is an open-ended question.

  • Single choice question: Suppliers can just one response from a predetermined list you define. This is a closed-ended question.

  • Multiple-choice question: Suppliers can choose multiple responses from a predetermined list you define. This is a closed-ended question.

When to use each type of question?

  • Free-text questions: When you have exploratory questions. When you want your suppliers suggest with alternatives and ideas. When suppliers need to give examples, study- cases, describe situations.

  • Single choice questions: When you need structured RFP responses. When you have Yes/No, True/False type questions, questions with ratings, or nominal scales.

  • Multiple-choice questions: When you need structured RFP responses. When suppliers need to provide a list of options, services, products, etc.


  • Free text questions: You get much more detailed information from your suppliers than through other types of questions.

  • Single choice questions / Multiple choice questions: You obtain structured data, which is very easy to compare and analyse. They’re simple. It’s much easier to click a button than to type in a response. Easier and faster for suppliers to answer.


  • Free text question: Data is not structured and it’s very hard to compare responses. Some suppliers might be discouraged thinking there is too much information to collect and provide. If not asked correctly, you will invite a very general answer that will not have much value.

  • Single choice questions / Multiple-choice questions: Suppliers can’t be creative, offer alternatives or what can be valuable details. If not asked correctly, suppliers might need more than the choices you provided and they will be confused.

Keep in mind that you need to always find a balance between:

  • asking a lot of questions (especially open-ended ones), but which might discourage suppliers participating, might create

  • delays, and you putting a lot of effort into analyzing them and,asking too few question, not providing enough information to you to take the right decision
