I want to integrate my form with Square, how many payments may i process for free within one month?

Please note that free plan has payment submission limit of 10 payments. If you want to add Square payment tool in form to receive payment submissions, the payment limit is same as your account submission limit. That means in free plan, you can receive 100 payment submissions through Square payment tool.
