@al3xicon Hello I am a solution architect here at Celigo and can confirm that
Integrator.IO does have the ability to create bills within NetSuite.
As to specifically how to accomplish this in relation to Purchase Orders what you could do is create a saved search within NetSuite of Purchase Orders that are “Pending Billing” and then using
Integrator.IO create an integration flow that will export that list of PO’s and then use that list to go back into NetSuite and create the vendor bills for each Purchase Order listed
