With Stampli, the entire procure to pay process happens in a collaborative software suite. Each invoice is turned into its own communications hub, allowing people across departments to fill in the blanks and answer questions so that payments are handled as efficiently as possible. Moreover, Stampli uses machine learning to recognize patterns around how the organization allocates cost, manages approval workflows and what data is extracted from invoices.
