From Day One to Day 100: How Finance Leaders Stabilize T&E After M&A

Travel and expense (T&E) is one of the most critical yet overlooked areas of post-merger integration. It touches every employee, represents one of the largest categories of corporate spend, and directly affects compliance and financial visibility across the combined organization. Yet 63% of executives say disconnected data makes compliance and spend management nearly impossible after an M&A transaction. The first 100 days determine whether integration succeeds or stalls.

The 100-day T&E integration roadmap for finance leaders

Pre-close: Lay the groundwork. Review reimbursement balances and travel spend with the M&A team. Identify policy gaps, manual process indicators, and define ownership of T&E policy, approvals, and reporting before day one.

Days 1–30: Establish visibility. Consolidate spend data from both organizations into a single dashboard. Flag out-of-policy expenses and high-ticket categories such as airfare and lodging. PwC research shows 53% of finance leaders say compliance technology led to faster identification and response to financial issues.

Days 31–60: Standardize processes. Align four key areas across the combined organization: expense categories, travel booking policies, reimbursement timelines, and approval workflows. Automate credit card reconciliation, receipt capture, and policy enforcement to reduce manual effort and errors.

Days 61–90: Drive strategic value. Use AI to audit expense reports for duplicate submissions, policy violations, and fraudulent receipts before reimbursement. Automate VAT/GST capture for cross-border compliance and build a rolling T&E forecast from historical spend data.

Days 91–100: Review and evolve. Assess integration progress and develop a long-term T&E strategy. SAP Concur customers realize an average of $1.6 million in cost savings and 406% ROI over three years, with a 5.1-month payback period.
