If we update to Bronze Level how many payment transactions will this provide?

Our Bronze plan offers you 1000 of submissions of any kind - regular, secure or payments as shown on the pricing page: www.jotform.com/pricing

When looking at the pricing you should note that the free plan is the only one that is limited separately by the various types of submissions, while the paid plans are limited only by the submissions counter.

Do let us know if you have any additional questions and we would be happy to answer the same :)
