CF7 with Paypal

I use CF7 as well as eStore plugins. I have a buynow situation where I need to collect data from customer and would prefer to do it during the initial purchase. Currently, the customer is directed to a booking form first, then has to come back to the store page to purchase the product. I would like to see if there is a way to make the form and the purchase work together. Is that possible?

Thank you,
