Approval routing is the set of rules that decides where a document goes for sign-off, in what order, and what happens if it stalls. Get it right and approvals flow in hours; get it wrong and they vanish into inboxes for days. This guide covers the building blocks and the mistakes to steer clear of.
The most common mistake is encoding the org chart instead of the actual decision. Before you configure any routing, map what genuinely needs to happen for a given document type: who truly must approve, where the order really matters, and where sign offs are independent of each other. Often a step everyone assumed was sequential turns out not to be – and spotting that is where most of the time savings come from.
Some approvals have to happen in order: a department head signs off before finance reviews the budget impact. Others are independent: legal and procurement can both review a contract at the same time, since neither needs the other’s answer first. Sequential routing makes sense where one decision feeds the next; parallel routing should be used everywhere else, because forcing independent reviews into a queue is pure added delay. A well-designed flow uses sequential steps only where the dependency is real.
Routing should adapt to the document. A low-value invoice might need just one approver, while a high-value one needs an extra sign-off. A standard contract might skip legal review, while a non-standard one requires it. Conditional rules – based on amount, document type, department, or other fields – let the same workflow zip the easy cases through and save the scrutiny for the cases that need it. The data driving those conditions usually comes straight from extraction, which is why workflow and intelligent document processing work best together.
Every step should have a time target – an SLA – and the system should track each one. Make the status visible so everyone can see what’s on time, at risk, or overdue. Then set up escalation: when a step misses its deadline, the document should be reassigned, bumped to a manager, or raised in priority automatically. Without escalation, an SLA is just a number; with it, the workflow corrects itself.
Watch out for a few recurring traps. Over-sequencing – forcing parallel work into a line – is the biggest source of avoidable delay. Single points of failure, where one unavailable approver halts everything, should be handled with delegation rules. Over complex flows with too many steps frustrate people and slow things down; simpler is usually better. And skipping the audit trail throws away the accountability that’s often the main reason to automate in the first place.
