Just curious, any one you have push your company invoices to Walmart portal ? Right now we are entering manually the invoice in Walmart portal, I hope Netsuite as a solution

Yes, there is a "van" that can connect Netsuite and Walmart

Great. When you say "van" are you talking about an EDI ?

yes

There are several suiteapps that can do EDI. SPS Commerce is one, go look on SuiteApps.com for others
