How a Target Routing Guide Works
A Target Routing Guide starts with an incoming transaction or document. The workflow evaluates relevant attributes against routing rules and identifies the appropriate destination. That destination may be an individual approver, department, processing queue, ERP function, or specialized exception workflow.
- Capture the item: Identify the transaction, document, request, or business event entering the workflow.
- Evaluate conditions: Apply rules based on value, entity, department, vendor, account, or transaction status.
- Determine the target: Select the appropriate person, team, system, or workflow stage.
- Complete the route: Record the resulting approval, correction, processing action, or escalation.
For example, a procurement request can route to a department manager when it falls within that manager's authority and move to a finance approver when the transaction exceeds a defined threshold.
Target Routing in Procurement
Procurement workflows commonly use target routing to connect requisitions, sourcing, approvals, purchase orders, and procure-to-pay controls. A purchase order can be directed to different approval paths according to spend value, business unit, category, or authorization level.
The routing structure should reflect the organization's procurement policy and delegation of authority. Approval Routing specifically determines which authorized person or role should review and approve a transaction. This helps establish accountability while maintaining visibility over purchasing decisions.
Organizations can also use Flexible Workflow structures to tailor procurement routing by department, role, threshold, or exception condition. Such rules allow approval paths to adapt to different business requirements while maintaining defined controls.
For broader procurement process design, a purchase order approval system can connect approval matrices, delegation of authority, SLA-based routing, and spend controls across the procurement lifecycle.
Target Routing for Invoices
Accounts payable teams can apply Target Routing Guides to determine where supplier invoices should go after capture and validation. Routing conditions may include supplier, legal entity, purchase order, invoice amount, GL account, tax status, matching result, or approval requirement.
Invoice Routing describes the controlled movement of invoices between processing stages, reviewers, and approvers. A correctly matched invoice may follow a standard approval route, while an invoice containing a price, quantity, or coding variance can be directed to a specialized review queue.
Invoice workflow design can also incorporate Custom Workflows for Invoice Processing, enabling role-based exceptions, dynamic approvals, and rule-driven paths for different invoice scenarios.
Teams assessing invoice technology can consult Invoice Software 2025: AI-Ready AP & Billing Guide. for additional context on invoice capture, extraction, validation, matching, GL coding, approval, posting, accuracy, and straight-through processing.
Exception Handling and Target Selection
Target routing becomes particularly useful when transactions do not follow the standard workflow. An exception may result from a missing field, unmatched purchase order, approval threshold, duplicate indicator, or unusual accounting requirement. Exception Routing directs these items toward the appropriate specialist, reviewer, or resolution process.
A clear exception path prevents unusual transactions from being treated like routine items. The routing guide can identify the responsible role, required evidence, escalation point, and next processing stage for each defined exception category.
Target Routing and ERP Systems
ERP integration provides the data required to make accurate routing decisions. Fields such as company code, cost center, vendor, purchase order, GL account, transaction amount, and approval status can determine the target destination.
Organizations extending finance workflows around an ERP can use the ERP Automation Guide: Modules & Playbooks to understand how ERP modules, integrations, and AI-enabled workflows can work together while maintaining enterprise transaction records.
A Target Routing Guide should clearly identify which system owns each relevant data field and which system records the final outcome. This improves consistency when information moves between procurement, accounts payable, ERP, and approval workflows.
Best Practices for Target Routing Guides
An effective Target Routing Guide should use clear conditions, identifiable destinations, and documented ownership. Rules should be specific enough to produce consistent routing decisions while remaining aligned with current organizational policies.
- Define routing conditions using reliable transaction and master-data fields.
- Align targets with current approval authority and organizational responsibilities.
- Create distinct routes for standard transactions and recognized exceptions.
- Maintain an auditable record of routing decisions and completed actions.
- Review rules when policies, organizational structures, ERP configurations, or workflows change.
Regular review also helps ensure that routing destinations remain accurate as departments, approval authorities, vendors, entities, and transaction types evolve.
Summary
A Target Routing Guide establishes rules for determining where a transaction, document, or request should go next and identifies its intended processing destination. In finance and procurement, it can coordinate purchasing approvals, invoice processing, exception handling, and ERP workflows. Clear routing conditions, defined ownership, and appropriate exception paths support consistent operations, stronger controls, and better financial visibility.
