Can JotForm provide flexibility as our business requires in terms of pricing?

Is there flexibility to meet our future business needs whether they grow or in the rare case reduce?

Yes, if you take a look at our pricing page here: http://www.jotform.com/pricing

You will be able to see all of the plans being offered, including free one if, as you have mentioned in a rare case, your business needs reduce. If you however need much more than it is offered on the pricing page, there are other plans available that we would be able to offer you, but if that time comes, do let us know and we will connect you to the right people to set it all up.
