Map what actually happens.
Follow one real item from arrival to completion. Record the systems it touches, the people who approve it, and the points where information is copied or checked. Include workarounds. They often reveal the requirements that a tidy process diagram misses.
Separate a trigger from a decision.
An incoming invoice is a trigger. Deciding whether it is valid is a separate step. Document the rules, the information required, and the person responsible for exceptions before choosing the automation tools.
Design for repetition and failure.
A workflow needs a plan for duplicate events, unavailable integrations, and partially completed actions. Agree on safe retries and a visible exception queue. The aim is a recoverable process with clear ownership.
Keep people in the right places.
An approval step should show the reviewer what matters: the source, the proposed action, and the reason it needs attention. Keep consequential decisions explicit. An automated notification is useful only when someone knows what to do next.
Measure the whole journey.
Compare completion time, exception volume, and the amount of manual handling before and after a pilot. Review the quality of completed work alongside speed. Expand the automation when the first workflow is understandable and dependable.
Bring your workflow, your constraints, and the outcome you want to achieve.
