If I use paypal as my submit button, does it count as total payments submitted?

If I use paypal as my submit button, does it count as total payments submitted? Or do I have unlimited submits due to the fact I am using paypal to accept payments.

Yes, it will be counted as total payments submitted, since you have integrated a payment field in the form and payment is being made as submission.
