A subscription covers the costs of respondents and emails. Depending on your subscription model you have one or more additional free settings.
If you wish to use even more additional products or services this is, of course, still possible.
You will receive an invoice for these extra services at the end of the month. If you still have available credits, these costs will be deducted from your credit balance depending on your payment type.
What are extra services?
Extra services can be custom programming, consulting, a survey check-up, etc. Anything that is not included in your subscription.
You can find a list of our services and a price indication on our Services page.
