When a portfolio company signs an LOI to sell a business unit, the transition services agreement is often the first place the deal starts leaking value. The seller wants a short TSA to clean up its balance sheet. The buyer wants a long one to avoid stranding the carved-out entity. Neither side has priced the work accurately, and the operating partner discovers this in confirmatory diligence, usually weeks before Day 1. A TSA management consultant in M&A exists to close that gap: to scope the services, price them, sequence the exit, and hold both sides to the schedule so the carve-out does not run past its milestones and burn management time it cannot spare.
This guide is for the operating partner, deal team member, or portfolio CFO who already has budget and now has to decide what to buy and how to judge the work. It assumes you know what a TSA is and skips the definitions.
1. Decide what the consultant is actually accountable for
The single most common scoping error is buying a document instead of an outcome. A TSA management consultant can produce a service catalog and a cost schedule in three weeks and call it done. That leaves the hard part, running the services to a clean exit, unowned. Before you sign, name the outcome you are buying and the owner on your side who signs off on it.
There are three realistic scopes, and you should choose one deliberately rather than let the engagement drift across all three:
- TSA design. The service catalog, cost allocation methodology, duration by service line, and exit criteria. This is diligence-adjacent work and belongs before signing.
- TSA negotiation support. Turning the design into schedules both sides will sign, with pricing that survives the seller’s finance team and the buyer’s covenant model.
- TSA exit management. Running the standing meeting, tracking actual versus plan on each service, and driving the carved-out entity to stand up its own capability so services can be terminated on schedule.
The exit management scope is where enterprise value is protected or lost, because TSA overruns quietly add cost to both the RemainCo and the divested business. Bain’s annual private equity report has tracked how holding periods and value-creation timelines compress margin for error, which is exactly the pressure a mismanaged TSA adds to. You can review Bain’s work at the Bain Global Private Equity Report.
2. Tie the TSA scope to the technology separation, not around it
Most TSA services are technology and data services in disguise: shared ERP, shared CRM, email, identity, payroll systems, data center access. If your TSA consultant treats these as line items to be billed rather than systems to be separated, the schedule will slip because nobody owns the migration underneath the service. The TSA is the meter running while the separation happens; the separation is what stops the meter.
This is why the TSA workstream and the technology due diligence findings have to be read together. The diligence tells you which systems are entangled and how hard they are to split; the TSA prices the time it takes to split them. When these are run by different teams that never reconcile, you get a TSA priced on optimistic separation timelines and a separation plan that ignores the TSA clock.
For the mechanics of separating the underlying systems, the decisions overlap heavily with hiring a divestiture technology separation consultant and with the broader question of divestiture IT consulting in private equity. Judge whether your TSA consultant can speak to both, or whether they will hand you a schedule and disappear when the migration gets hard.
3. Judge the pricing methodology before you judge the price
A TSA cost schedule that looks precise is not the same as one that is defensible. The seller will typically price services at fully loaded cost plus a markup, and the buyer will push back on both the cost base and the markup. Your consultant’s job is to make the methodology legible so the negotiation is about numbers, not about trust.
What a defensible schedule shows
- The cost base for each service, with the allocation driver named (headcount, transaction volume, storage, seats).
- A fixed versus variable split, so the buyer is not paying a fixed allocation for a service they can ramp down.
- Step-down pricing tied to the exit plan, so the seller has a financial reason to help the buyer exit on time.
- Termination and extension terms priced separately, so an overrun has a known cost rather than an argued one.
The accounting treatment of TSA costs and the way they flow through quality of earnings is not a place to improvise. The AICPA and CIMA maintain guidance relevant to how these separation costs are classified, and the SEC filings of larger carve-outs show how public acquirers disclose TSA arrangements. Keep the classification questions with your finance team and your QoE provider; keep the operational pricing with the consultant.
4. Insist on exit criteria and a standing governance rhythm
A TSA without exit criteria is an open-ended cost. Every service in the schedule needs a defined condition that ends it: the new system is live, the data is migrated and reconciled, the team is hired and trained. If the criteria are written as dates alone, the service will extend, because dates slip and nobody is accountable for the underlying readiness.
The governance rhythm is where a good consultant earns the fee. This is the same discipline you would expect from a merger integration management office, applied to the reverse problem of pulling two entities apart. A weekly service-owner meeting with a live tracker of actual versus plan, a risk register with named owners, and a monthly steering review for the operating partner keeps the TSA from becoming a background cost nobody watches.
McKinsey’s research on operational value creation and BCG’s work on principal investors both point to governance cadence as the difference between plans that land and plans that drift. You can find the relevant research at McKinsey and BCG.
5. Connect the TSA plan to the first 100 days of the standalone entity
The carved-out business has to run itself when the last TSA service terminates. That means the TSA exit plan and the entity’s first 100 days plan are the same plan viewed from two ends. Every service you are exiting corresponds to a capability the standalone entity has to build, staff, and prove before termination.
This overlaps directly with hiring a Day One readiness consultant and with the mechanics of CRM and ERP separation and integration, where the revenue systems are usually the last and hardest services to exit because they touch customers directly. Judge whether your TSA consultant sequences these correctly, exiting low-risk back-office services first and holding customer-facing systems until the replacement is proven.
6. Score the consultant against evidence, not credentials
The market for M&A advisory around carve-outs is crowded, and a well-known name is not the same as a team that will run the exit. Ask for the artifacts they produce on other engagements, redacted: a sample service catalog, a cost schedule with the methodology visible, a risk register, a steering deck. If they cannot show the working documents, they are selling a proposal, not a practice.
Data providers give useful context on how active carve-out activity is and who advises on it. PitchBook, Preqin, and S&P Global Market Intelligence track carve-out and divestiture volume, while Private Equity International, Buyouts, and PE Hub cover the deals themselves. For the governance and accounting side of separation, the Harvard Law School Forum on Corporate Governance and Harvard Business Review’s M&A coverage are worth reading before you scope the engagement.
If your carve-out is one leg of a buy-and-build, the same judgment questions apply to roll-up integration services and to running an outsourced RevOps function in the standalone entity once it is on its own systems.
7. A checklist before you sign the engagement
- The scope names one of design, negotiation, or exit management as the primary outcome, with an owner on your side.
- The TSA workstream reconciles with technology diligence findings on system entanglement.
- The cost schedule shows the allocation driver and fixed/variable split for every service.
- Step-down pricing gives the seller a financial reason to help you exit on time.
- Every service has a readiness-based exit criterion, not just a date.
- There is a weekly service-owner meeting, a live actual-versus-plan tracker, and a monthly steering review.
- The exit sequence holds customer-facing systems until their replacements are proven.
- The consultant showed redacted working artifacts, not just a pitch.
Run each engagement candidate against these eight lines. A team that cannot answer six of them clearly is a design shop, and you will still need someone to run the exit.
Where to take this next
If you are scoping a carve-out and need a TSA plan tied to the technology separation and the standalone entity’s first 100 days, review the M&A advisory and PMI sprint approach in the DevriX private equity practice, built to run the exit rather than hand you a schedule.
