Question: Would rest_suite suffice to post a CashSale order getting NetSuite to process transaction?

[fmalina]

Would rest_suite suffice to post a CashSale order (create customer, add line items, card details) getting NetSuite to process transaction and create a record of the order for shipping?
Or does one need to use the SOAP based API to access advanced functionality.

If rest_suite is indeed capable enough for the job a bit of example code to get us started would be greatly appreciated. Thank you
