What is Business process automation?
Business process automation (BPA) is the use of software to run whole business processes, such as onboarding or invoice approval, across systems and teams using defined rules.
In more detail
BPA is the broader label for what workflow automation does at the level of a whole function. The unit is a process with an owner and a measurable outcome, such as procure-to-pay, hire-to-retire or order-to-cash. Typical building blocks are forms, rules engines, system integrations, document capture and approval steps. Older BPA suites relied on fixed rules and struggled with unstructured input. AI now handles reading and classification, while rules and approvals keep the process controlled. The practical question is scope. Automating a whole process at once tends to stall, so we start with one painful stage, prove it, then extend to the neighboring ones.
Example
A distributor automates purchase-to-pay one stage at a time. First, invoice capture and matching. Next, approval routing. Last, payment-run preparation. Each stage ships on its own and reports its own time saved.
