# The 60-Day M&A Playbook: Integrating Acquired Entities into NetSuite OneWorld

### The Post-Merger Financial Fog

In strategic M&A and private equity buy-and-build strategies, speed of operational integration dictates deal IRR. Every month an acquired company remains on a disconnected accounting system (QuickBooks, Sage, legacy ERP), financial visibility is compromised.

The traditional post-merger accounting workflow is notoriously inefficient:
- The corporate controller spends 10 to 15 days every month manually combining trial balances across disparate systems in Excel.
- Chart of Accounts naming conventions conflict.
- Intercompany eliminations are estimated on spreadsheets, creating substantial **Sarbanes-Oxley (SOX) Material Weakness risks** before board audit committees.

When executives ask legacy ERP consultancies for an integration roadmap, they are quoted **12 months and $500,000+**.

A full year of flying blind is unacceptable.

### The Speed-to-Market Solution: The 60-Day OneWorld Framework

DataOngoing executes our **60-Day NetSuite OneWorld M&A Integration Playbook**, transitioning acquired operating entities into the corporate ERP in eight disciplined two-week sprints:

```text
[Weeks 01-02] COA Harmonization: Automated Account Crosswalk & Subsidiary Provisioning
[Weeks 03-04] Master Data Cleanse: Item, Customer, and Vendor Master Standardization
[Weeks 05-06] Financial Balance Migration: 12-Month Historical Trial Balances & Subledger Cutover
[Weeks 07-08] Parallel Validation: Automated Intercompany Eliminations & Real-Time Board Reporting
[Day 60]     Full Production Cutover: 100% Consolidated Financial Visibility
```

#### Architectural Pillars:
1. **The Day-1 COA Rosetta Stone:** We map legacy account strings directly to the standardized Parent Chart of Accounts using automated transformation scripts, avoiding months of inter-departmental committee debate.
2. **Clean Balance Cutover:** Rather than contaminating the new environment with ten years of dirty historical transactions, we migrate pristine monthly summary Trial Balances and cut over live operational subledgers (Open AR, Open AP, and Physical Inventory by lot).
3. **Automated Intercompany Eliminations:** Native OneWorld elimination subsidiaries clear mirrored intercompany balances in seconds, eliminating manual spreadsheet elimination journals forever.
