I believe the main problem with procurement in most companies is the lack of transparency. When requests arrive by email, approvals are processed in chats, and invoices are sitting in the accounting department, it's difficult to understand how much money has already been reserved.
Precoro Procure-to-Pay system integrates all processes: requests, orders, suppliers, and invoices. Plus, you can set up automatic approval rules and control your budget even before making a purchase.
