RECONCILIATION PROCESS:
  Step 1: Gather supporting evidence
    - Bank statements (from bank portal)
    - Sub-ledger detail (from ERP)
    - Third-party confirmations (investments, loans)
    - Prior period reconciliation (carry-forward)
    - Journal entries posted (current period)
  
  Step 2: Perform reconciliation
    - Match GL balance to supporting detail
    - Identify differences (timing, errors, omissions)
    - Age differences (current month vs. prior)
    - Classify items (recurring, one-time, aged)
  
  Step 3: Investigate differences
    - Timing differences: Normal (clear next period)
    - Errors: Correction entry (with approval)
    - Omissions: Additional entry (with approval)
    - Unexplained: Escalate to Controller
    - Aged items (>3 months): Root cause + action plan
  
  Step 4: Document & certify
    - Reconciliation template (standard format)
    - Supporting documentation (attached)
    - Prepared by: Accountant (designated per account)
    - Reviewed by: Senior accountant / Supervisor
    - Certified by: Controller (HIGH accounts) / Manager (MEDIUM)
  
  Step 5: File & archive
    - Storage: BlackLine / SharePoint (digital)
    - Retention: 7 years (compliance)
    - Audit trail: Version history, approval log
    - Access: Restricted (Finance only)

## Reconciliation Quality & Controls

### Governance & Best Practices

```
RECONCILIATION GOVERNANCE:
══════════════════════════

ACCOUNT OWNERSHIP:
  Each reconciliation has a designated:
    - Preparer: Accountant responsible for execution
    - Reviewer: Senior accountant / supervisor
    - Certifier: Controller (HIGH) / Manager (MEDIUM-LOW)
  
  Segregation of duties:
    - Preparer ≠ Reviewer (mandatory)
    - Reviewer ≠ Certifier (for HIGH accounts)
    - Account owner ≠ transaction approver (where possible)

QUALITY STANDARDS:
  Documentation requirements:
    - Standard template (all reconciliations)
    - Supporting evidence (attached, indexed)
    - Narrative explanation (for all differences)
    - Aging analysis (for outstanding items)
    - Prior period carry-forward (clear linkage)
  
  Review criteria:
    - Completeness (all accounts reconciled)
    - Accuracy (GL balances match supporting detail)
    - Timeliness (completed within close calendar)
    - Appropriateness (classification of items)
    - Resolution plan (aged items, exceptions)

AGED ITEM MANAGEMENT:
  Policy:
    0-30 days: Normal (no action required)
    31-60 days: Review required (action plan)
    61-90 days: Escalation to Controller
    90+ days: Write-off / adjustment (with CFO approval)
  
  Current aged items: $0 (clean — no aged items)
  Trend: Improving (Q3 had $45K aged → Q4: $8K → Q1: $0)

MONTHLY RECONCILIATION CHECKLIST:
  ┌───────────────────────────────────┬──────┬──────┐
  │ Check Item                        │ Q4   │ Q1   │
  ├───────────────────────────────────┼──────┼──────┤
  │ All accounts reconciled by Day 10 │ ✓ 100%│ ✓ 100%│
  │ Review completed within 2 days    │ ✓ 98% │ ✓ 100%│
  │ Certification within 1 day        │ ✓ 95% │ ✓ 100%│
  │ No items aged >90 days            │ ✓     │ ✓     │
  │ Documentation complete            │ ✓ 100%│ ✓ 100%│
  │ Exceptions resolved               │ ✓ 96% │ ✓ 100%│
  │ Audit trail maintained            │ ✓ 100%│ ✓ 100%│
  │ Prior period items cleared        │ ✓ 100%│ ✓ 100%│
  └───────────────────────────────────┴──────┴──────┘
  
  Overall quality score: 100% (Q1 2025) — EXCELLENT
  Trend: Improving (Q3: 98% → Q4: 99% → Q1: 100%)

INTERNAL AUDIT REVIEW:
  Last review: November 2024 (Internal Audit)
  Scope: Sample of 12 reconciliations (HIGH + MEDIUM)
  Findings: 0 deficiencies
  Recommendations: 1 (minor — enhance narrative for recurring items)
  Status: ✓ Satisfactory — no exceptions

CONTINUOUS IMPROVEMENT:
  Automation expansion:
    Current: 38/48 accounts automated (79%)
    Target: 45/48 (94%) — add 7 more accounts
    Timeline: Q1-Q2 2025
    Benefit: Additional 5 hours/month time savings
  
  Rule optimization:
    Auto-match rate: 87%
    Target: 92%
    Action: Refine matching rules (quarterly review)
  
  Close acceleration:
    Current: Day 8 average completion
    Target: Day 6
    Action: Parallel processing (additional resources)
```

## Integration Points

- ERP/GL (NetSuite, SAP): GL balances, sub-ledger detail, journal entries
- Reconciliation platforms (BlackLine, Cadency): Automated matching, workflow
- Banking platforms (API): Bank statements, account data, transaction detail
- BI platforms: Reconciliation dashboards, exception reports
- Document management (SharePoint): Reconciliation storage, evidence
- Internal audit platforms: Audit trail, review evidence
- Alerting platforms (Slack, email): Exception notifications, workflow reminders
- Data analytics tools: Trend analysis, aging analysis, exception detection

## Edge Cases

- **Large balance difference**: Root cause investigation; potential error; adjustment entry; management escalation
- **Long-standing aged items**: Write-off assessment; management approval; tax implications; root cause elimination
- **System migration**: Dual reconciliation; data mapping; period-end cutover; validation
- **Bank error**: Bank communication; correction timeline; temporary adjustment; follow-up
- **Fraud indicators**: Immediate escalation; forensic investigation; law enforcement; management notification
- **Foreign currency timing**: FX rate differences; adjusting entries; documentation; consistency
- **High transaction volume**: Processing time; resource allocation; batch processing; automation
- **Account restructuring**: New account mapping; historical data; reconciliation redefinition
- **Regulatory requirement**: Enhanced documentation; external auditor evidence; compliance timeline
- **Force majeure / banking disruption**: Alternative evidence; manual reconciliation; risk assessment
