A vendor self-service app, also commonly known as a supplier self-service app, is an integrated online platform shared by vendors and its trading partner. The vendor self-service app is used for entering supplier information, submitting documents, displaying status, and communicating. With a Vendor app, submitting documents like electronic purchase orders, contracts, and vendor invoices for payment is more accessible. It also reduces the costs of procurement cycles by improving the exchange of business documents and shortening the time it takes to process the content of these documents.
