Current-state process versus the governed, automation-ready future state this blueprint delivers.
CURRENT STATE
1
Supplier email received
2
Manual triage by individual
3
Approval via email or chat
4
Spreadsheet tracking
5
ERP update after the fact

FUTURE STATE
1
Exception raised in ERP
2
Auto-categorised by type
3
Owner auto-assigned

ARCHITECTURE PATTERN
Recommended system layers from data source to governance output.
L1
LAYER 1
ERP / Source System
SAP, Oracle, or NetSuite — the authoritative record for AP transactions and supplier master data.
L2
LAYER 2
Exception Intake Layer
Standardised intake form or API endpoint that captures all exceptions at source, replacing email and chat.
L3
LAYER 3
Workflow Engine
Routes exceptions to the correct owner based on type and threshold rules; manages SLAs and escalations.
L4
LAYER 4
Approval Service
Digital approval with rationale capture; enforces the approval matrix and records decision provenance.
L5
LAYER 5
Audit Repository
Immutable record of every exception event, decision, and evidence attachment — retrievable by auditors without interview.
L6
LAYER 6
Reporting Layer
Controller dashboard showing exception volume, resolution time, SLA compliance, and governance score trend.
INTEGRATION POINTS

RECOMMENDED TOOL STACK
Tool categories and named options for each capability layer. Final selection depends on existing stack and licensing.
CATEGORY 1

Power Automate
ServiceNow
Jira Service Management
Route exceptions through governed approval chains with SLA tracking
CATEGORY 2
Document Control
SharePoint
Confluence
ServiceNow GRC
Store approval rationale, evidence, and audit trail in a retrievable system of record
CATEGORY 3

DELIVERY ROADMAP
Sequenced implementation programme from governance foundation to closed-loop optimisation.
PHASE 1 · LIVE NOW
Governance Foundation
Weeks 1–4
▸Document approval matrix
▸Define exception taxonomy
▸Assign ownership
▸Establish evidence retention policy
MILESTONE
Approval matrix published; zero exceptions resolved outside system
PHASE 2
Workflow Automation
Weeks 4–10
▸Configure intake form
▸Build routing rules
▸Implement approval workflow
▸Connect to ERP
MILESTONE
All exceptions flowing through governed workflow; audit trail complete
PHASE 3
AI-Assisted Triage
Weeks 10–16
▸Train categorisation model on historical data
▸Implement auto-assignment
▸Deploy anomaly detection for high-value exceptions
These governance conditions must be confirmed before automation can be safely deployed on this process. Meridian does not recommend automating until all gates are met.
Approval matrix documented and published to all AP staff
Governance
Exception categorisation standardised with taxonomy agreed
Governance
Evidence retention rate above 95% for 60 consecutive days
Audit Trail
No exceptions resolved outside the system for one full period
Audit Trail
Deputy coverage in place for all critical approval roles
Dependency
Governance score above 65 (Governed band)
Governance
Readiness gates are governance conditions, not technical prerequisites. Each gate maps to a source dimension: Governance score, Audit trail completeness, Dependency risk, or Drift status.
