M&A- From TSA to Synergy: The Case for Designing Your Exit at the TSA Drafting Table

If you have ever been through a TSA exit, you know the drill; high probability they almost always run late, drag on for months longer than planned, and eat away at deal value.

But here is the thing, the smoothest integrations I have seen don not wait until Day 1 to start planning. And they do not get stuck in endless pre-close “what if” scenarios either.

The real sweet spot? Doing just enough light-touch planning in diligence to see what is coming, and then getting serious the moment the TSA is being drafted. That is the point when certainty is high, and when you can still influence scope, SLAs, timelines, and costs.

1. Why It Matters

• PwC found that early TSA exits can lift deal value by 5–7%.

• KPMG’s research shows that with aggressive pre-close planning; TSA durations can shrink from 24 months down to just 2–3.

Mini Case: One buyer facing a $15M annual TSA cost applied the 5R Framework and exited in 12 months instead of 24; saving $15M and accelerating operational independence.

2. Start Small in Diligence

This is not about building the full PMI plan before a deal even closes. It’s about smart discovery:

• Mapping which core services are shared (ERP, CRM, payroll, infrastructure, etc.)

• Spotting high-risk dependencies and stranded functions

• Sketching what Day 1, Day 90, and Steady State might look like

Low cost. High payoff. And it makes the TSA drafting table a whole lot less painful.

3. Focus on Five Workstreams

Once you hit the TSA phase, you need more than sketches. You need blueprints. In my experience, the critical workstreams are:

• Business Systems – ERP, CRM, HCM, MES/PLM; clean cutovers matter most here

• Infrastructure – Contain costs and control migrations

• Collaboration & Culture – Tools keep people working, but aligned culture keeps trust intact

• Reporting & Analytics – You cannot prove or protect deal value without them

• Security & Compliance – Regulations, data integrity, threat management, the foundation you cannot skip

4. A Timeline That Works

Here’s the rhythm that accelerates TSA exits without adding risk:

• Diligence: Light scoping and dependency mapping

• TSA Drafting: Get detailed, sequence cutovers, and bake in MVP/cloning options

• Signing → Day 1: Lock terms, mobilize teams, keep business running

• Day 90: Quick-win migrations; start showing value

• Steady State: TSA exit, synergies realized

5. The 5R Lens

Applied to every workstream: Remove | Replace | Reduce | Retain | Realign

When making decisions in any workstream, I run everything through the 5R filter:

• Remove redundant apps and seller contracts

• Replace legacy tools with buyer-standard platforms

• Reduce duplicate vendors and infrastructure

• Retain what is high value for continuity

• Realign functions to the buyer’s operating model

Think of it less like a checklist and more like a mindset, it helps leaders cut through noise and focus on value.

6. The Payoff

Exiting the TSA faster does not just save money (though that is huge). It also:

• Unlocks harmonized ERP and reporting sooner

• Reduces cost drag with independent infrastructure

• Protects customer continuity

• Creates a sense of cultural momentum inside the new organization

And honestly, that last point is often the most overlooked. In every integration I have seen, momentum, cultural and operational, compounds value faster than spreadsheets ever show.

The Question I’ll Leave You With

When the TSA draft lands on the table, will you already have your PMI blueprint in place, or will you still be sketching ideas while the clock is ticking?
