What is approval workflow software and how does it improve business processes?

Approval workflow software automates the submission, routing, review, approval, rejection, and tracking of business requests such as purchase orders, expenses, invoices, discounts, and contracts. Modern solutions can use rule-based or AI-assisted routing, automate reminders and escalations, integrate with ERP and CRM systems, and maintain an audit trail. This helps reduce manual work, improve process visibility, and move routine approvals through the business faster while keeping important decisions under human control.
