An Invoice Contact is a person who ensures that an invoice is
submitted to an upstream contractor for payment. In Procore, an invoice
contact is always an employee of the designated 'Contract Company' on a
purchase order or subcontract. The contract company is the party responsible
for performing work and/or supplying materials for a project. For customers
in the United States using Procore's Progress Billings tool, this term
is synonymous with progress billing contact.
