What should you look for in a form builder?

A form is quickly made, but the answers stay with the vendor. Look at the limit of the free plan, where the answers are stored and whether people can pay in the form.

  1. Limit of the free plan

    Free form builders often stop at a number of forms or responses per month. If you hit that limit, the form closes or you have to upgrade in the middle of a campaign.

    Ask the vendor

    How many forms and responses per month do I get for free, and what happens to my form if I go over that limit?

  2. Price per response or per user

    Some form tools charge per user, others by the number of responses or with a fixed amount for the whole team. Work it out with the number of responses you expect in a busy month.

    Ask the vendor

    Do I pay per user or by number of responses, and what does it cost if I get more responses in a month than my plan allows?

  3. Answers stored in the EU

    Form answers contain names, email addresses and sometimes health or financial data. Many form tools come from the US; check whether EU storage is standard or only on an expensive plan.

    Ask the vendor

    Are the answers to my forms stored in the EU by default, and if not, on which plan can I choose EU storage?

  4. Data processing agreement for your respondents

    The vendor stores the answers of your customers and respondents on your behalf. That makes them a processor, and the GDPR requires a data processing agreement, also with a free account.

    Ask the vendor

    Does your data processing agreement also apply to the free plan, and which sub-processors get to see my respondents' answers?

  5. Payment in the form

    With a payment step in the form you handle registrations, orders or deposits in one go. Check which payment service it runs through and whether customers can pay with iDEAL.

    Ask the vendor

    Can people pay in the form, through which payment service, and can customers pay with iDEAL there?

    We do not have a filter for this yet. Ask the vendor.

  6. Answers to your other tools

    A registration often has to go on to your mailing list, CRM or spreadsheet. With an integration you do not have to retype or export answers.

    Ask the vendor

    Do answers go to my email tool, CRM or spreadsheet automatically, and is that integration included in my plan?

  7. Form in Dutch

    Your respondents see buttons, error messages and the thank-you page. If those are in English while your questions are in Dutch, people drop out sooner.

    Ask the vendor

    Can I set the buttons, error messages and thank-you page of the form to Dutch?
