Answer:
Yes, it is possible to use both an Accounting Integration and PunchOut integration at the same time. Purchase Orders/Bills will sync to your Accounting/ERP Software, but the Vendor must be manually created in your Accounting Software with the exact name as applicable:
Amazon Business Canada (PunchOut)
Amazon Business Germany (PunchOut)
Amazon Business Spain (ES) (PunchOut)
Amazon Business UK (PunchOut)
Amazon Business USA (PunchOut)
Global Industrial (PunchOut)
Grainger (PunchOut)
Home Depot (PunchOut)
Identity Works (PunchOut)
Marijuana Packaging (PunchOut)
Staples USA (PunchOut)
Staples Professional Canada (PunchOut)
Thermo Fisher Scientific (PunchOut)
Uline (PunchOut)
Zageno (PunchOut)
The Master Data sync will ignore vendors containing "PunchOut" and will not create a duplicate vendor in Procurify.

If you sync purchase orders and/or inventory items to NetSuite, please also see Syncing Vendor and Account Codes between NetSuite and Procurify (PO and Inventory Sync)
