SUBSTRATE AUDIT OS · R2R
Close / reconciliation
Convert a dependency-heavy, individually-held close process into a documented, deputised, and system-enforced workflow that is repeatable, auditable, and safe to automate.

TARGET OPERATING MODEL
Current-state process versus the governed, automation-ready future state this blueprint delivers.
CURRENT STATE
1
Close sequence held in individual memory
2
No documented runbook
3
Late journals accepted informally
4
Variance commentary prepared ad hoc
5
Sign-off via email
6
No deputy coverage for key roles
→
FUTURE STATE
1
Close runbook distributed to all owners
2
Steps completed in documented sequence
3
Cut-off enforced in system
4
Late journals via exception workflow only
5
Variance commentary from template
6
Controller sign-off captured in system
7
Full close pack archived
8
Governance score updated post-close
ARCHITECTURE PATTERN
Recommended system layers from data source to governance output.
L1
LAYER 1
Close Task Manager
System of record for the close sequence — each step, owner, deadline, and completion status visible in real time.
L2
LAYER 2
Cut-off Enforcement Layer
System-enforced hard cut-off; post-cutoff entries require governed exception approval with rationale.
L3
LAYER 3
Reconciliation Platform
Preparation and sign-off of all reconciliations in system; multi-level approval captured and retained.
L4
LAYER 4
Commentary Workspace
Template-based variance commentary prepared in system; peer review and controller sign-off workflow.
L5
LAYER 5
Deputy Registry
Named deputies for every critical sign-off point; access and training status tracked.
L6
LAYER 6
Close Performance Dashboard
Close cycle time, on-time completion rate, exception volume, and governance score trend for controller.

DELIVERY ROADMAP
Sequenced implementation programme from governance foundation to closed-loop optimisation.
PHASE 1 · LIVE NOW
Runbook & Deputy Foundation
Weeks 1–3
▸Document complete close runbook
▸Assign and train deputies
▸Create variance commentary templates
▸Communicate cut-off rules
MILESTONE
Runbook published; deputies in place; first close completed using runbook
PHASE 2
System-Enforced Controls
Weeks 3–10
▸Configure close task manager
▸Implement cut-off enforcement
▸Build sign-off workflow
▸Deploy template workspace
MILESTONE
All close steps tracked in system; cut-off enforced for two consecutive closes
PHASE 3
Reconciliation Automation
Weeks 8–14
▸Automate reconciliation preparation for standard accounts
▸Implement variance calculation
▸Connect to ERP for balance feeds
MILESTONE
Standard reconciliations auto-prepared; reviewer effort reduced by 40%
PHASE 4
Predictive Close Management
Ongoing
▸Predict close bottlenecks from historical patterns
▸Automate standard journals
▸Continuous governance re-baselining
MILESTONE
Close cycle time below target; governance score above 75
AUTOMATION READINESS GATES
GATES PENDING
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.
Close runbook documented and used for minimum two full cycles
Governance
Deputy coverage in place for all critical sign-off points
Dependency
Cut-off enforced in system — no exceptions outside workflow
Audit Trail
All reconciliations signed off in system for two periods
Audit Trail
Variance commentary completed within SLA for two consecutive closes
Governance
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.
