IN SHORT: WHAT YOU WILL LEARN
1There is no reliable ranking by name: carve-out support is chosen based on who executes, how fast they can be mobilized and what the contract guarantees.
2A carve-out is played out over four milestones: Deal, Day 1 Readiness, TSA execution, TSA exit. The separation date set at the Deal drives everything else.
3Four workstreams run in parallel: legal, people, operations, IT. Each has its own forgotten question, and that is where projects slip.
4Seller or buyer, the work is not the same: carve-in and post-acquisition transformation mainly require defining target processes and building the teams.
5Six questions to ask any provider before signing, FocusTribes included.
Which firms or freelance consultant networks can support a carve-out or post-merger integration?
No ranking by name holds up: the right choice depends on what you need to separate or integrate, who executes day to day and how fast they can be mobilized. Four types of players share the field, each with different strengths and blind spots. They are combined more often than they are mutually exclusive.
M&A advisory, IT services firms, platforms, independent consultant networks: who covers what
M&A and transaction advisory firms
What it covers well
Deal scoping, audit and due diligence, strategy and M&A advisory, synergy assessment, integration plans, multi-country teams, communication.
What to check
Who executes day to day (the team presented during pre-sales or junior consultants), what the advisory activity covers once the deal is scoped, and the cost of a dedicated team over the duration of the TSA.
IT services firms and integrators
What it covers well
Separation and migration of information systems, software package rollouts (ERP, CRM, payroll), IT capacity at scale.
What to check
The scope often remains technical: cross-functional steering (legal, HR, operations) is not always part of the offer.
Matching platforms
What it covers well
Speed of profile presentation, broad catalog of M&A consultants.
What to check
What the announced lead time really covers (some pages display 48 h at the top and “a few business days” in the FAQ) and the depth of experience: the most requested services there are upstream of the deal (valuation, due diligence, feasibility), not its execution.
Selective communities of independent consultants, including FocusTribes
What it covers well
Senior consultants who work within the client's team: program director, project manager, IT lead, finance consultant for the accounting separation, organization and transition HR consultant, PMO.
What to check
Upstream selection, the contractual setup and what the contract guarantees. FocusTribes identifies the right profile within 48 h and requires a minimum of 8 years of experience.
Advisory firm, platform or freelance network: when to choose which
An
advisory firm is suitable when the deal itself needs to be scoped (valuation, perimeter, synergies, strategic stakes). A large company with an internal project management office and a seasoned CIO does not have the same needs as a mid-sized company: the larger the organization, the more cross-department coordination weighs in the choice. A
network of independent consultants is suitable when the scoping is done and you need seniors who execute the separation or integration alongside your teams and your integrator. A
platform helps you compare profiles quickly; it requires you to check the real carve-out experience yourself. For the detail of roles by program phase, see
our article on the transformation team.
Business separation: the four milestones of a carve-out and what breaks when you miss them
A
carve-out is the sale by a company of a branch of its business, often as part of a strategic refocus; a
carve-in is the opposite operation, which absorbs a business. It is a full transformation project, with the same governance and adoption challenges as other enterprise transformation projects, but with a separation date that structures the entire schedule. In both cases, the project follows four milestones: the Deal, Day 1 Readiness, TSA execution and TSA exit. Detailed definitions can be found in
our article on the 4 pillars of a carve-in / carve-out project; here is what to lock down at each milestone.
The separation date is set at the Deal: the entire schedule follows from it.
To lock down
Legal and tax perimeter, global plan with a
realistic separation date, dedicated management program, financial, social, business and IT implications.
What breaks if you miss it
An unrealistic date: a carve-out requires substantial legal, technical and human preparation, and the entire schedule follows from it.
To lock down
Interim business and IT processes (operating models), contracts to transfer or split (customers, suppliers, licenses, usage rights), transferred teams, HR negotiations.
What breaks if you miss it
Business continuity from the very first day: without interim processes in place, Day 1 becomes a break.
To lock down
Services provided by the seller to the buyer, the buyer's target processes, data cleansing, cloned IT environment, teams built on the buyer side.
What breaks if you miss it
A dependency that sets in: the buyer stays under the TSA because its own processes and teams are not ready.
To lock down
Transfer of services, data and tools; an entity that is autonomous operationally, legally and technologically; access closed.
What breaks if you miss it
A business interruption, access that was not closed or poorly transferred data.
Why the separation date drives everything
The date set at the Deal is the anchor point of the 360° backward plan: each department places its steps in it (Day 1, TSA exit, training, migrations), and a Program Manager integrates them into a shared schedule. A poorly aligned or overly rigid plan causes deliverable delays and cost overruns. Since activities are interdependent, a cascading delay hits the other workstreams.
The TSA: an organized dependency, not a lasting solution
The TSA (Transition Service Agreement) frames the period during which the seller continues to provide services to the buyer. Its duration is defined in the sale agreement, the services are paid for and tracked by indicators, and they can extend as far as user support. We have no reliable average duration to give you: it is negotiated deal by deal, and in the meantime the buyer is already preparing the exit.
Carve-out support: the four workstreams to run in parallel
A carve-out affects the entire organization. Four workstreams move forward together, and each has a question that teams forget to ask while there is still time.
Secure the transfer of assets, contracts and authorizations.
The question that gets forgotten
Who holds the usage rights to the licenses, and which contracts need to be split rather than transferred?
Consult employee representative bodies from signing, size the teams, prepare managers and employment contract transfers.
The question that gets forgotten
Who leads the change for the teams that leave and those that stay?
Reorganize business processes and transfer production tools while ensuring operational continuity, without interrupting the business.
The question that gets forgotten
Are the transition operating models written before Day 1?
Migrate data, integrate or separate information systems, secure IT environments.
The question that gets forgotten
Which data scope is migrated, and who handles the RUN after cutover?
IT: clone, clean up, decommission
During the TSA, a cloned IT environment maintains the continuity of the information system with dedicated support; the buyer's CIO and the seller's CIO must agree on the functional scope of each service. At exit, the target systems go live, the final migrations are completed, data is cleansed (cleansing) and unnecessary interfaces are removed. Poor anticipation delays the cutover, causes data loss or jeopardizes business continuity. The data scope and RUN preparation (tools, ticketing, support, maintenance) are decided beforehand, not during.
Who owns what: sponsors and Program Manager
Governance rests on
sponsorship from the CFO and the CHRO and on a
full-time dedicated Program Manager, who coordinates the functional teams (finance, HR, business units), IT and legal, in other words all the departments involved. This is the first profile to secure, and the one where a senior independent consultant adds the most when the company has not carried out a business separation recently. For the split of the other roles, see
the transformation team by phase.

Carve-in, carve-out, post-acquisition transformation: what changes depending on which side of the table you sit on
The seller separates, the buyer integrates. The milestones are the same, but the effort does not weigh in the same place, and neither does the profile to mobilize.
Where the effort falls across the four milestones
Seller
Deal
Day 1
TSA exec.
TSA exit
Buyer
Deal
Day 1
TSA exec.
TSA exit
Seller
carve-out: it separates
What is at stake
Define the perimeter, split contracts and teams, make Day 1 possible, provide the TSA services.
Watch point
Service continuity during the TSA and data interdependencies.
Buyer
carve-in and post-acquisition transformation: it integrates
What is at stake
Define the target processes, build the teams that take over the business, prepare the TSA exit.
Watch point
An entity that arrives without autonomous infrastructure (ERP, invoicing, payroll) and whose data is hard to access before signing.
A buyer-side example: the Shiftmove carve-in
Shiftmove, a European provider of fleet management solutions, acquired Optimum, the French subsidiary of a major telecom operator. Optimum had no autonomous ERP, invoicing or payroll and relied on a TSA; its data remained inaccessible before signing. A
freelance program director from the FocusTribes community coordinated, between teams with different cultures (a scale-up with agile ways of working and a more corporate operator partner), the ERP migration, the takeover of HR contracts, payroll, the choice of cloud provider and the takeover of the vehicle fleet, with reporting to top management. At the end of the assignment, Shiftmove offered him a position in the company. For Manuel Schuler, General Manager of Shiftmove France, the key is that the provider “finds the right people”. The details are in
the Shiftmove case study and in
a consultant's testimonial on managing a carve-out.
Six questions to ask before choosing your carve-out support
Apply this grid to any provider, ourselves included.
1
Who will work on my project, and have they already led a carve-in or a carve-out (proven specialization, not just transformation project experience)?
A good answer
A named profile, with references from comparable operations (scope, duration, role).
Red flag
A profile “to be confirmed” or replaceable without notice.
2
How quickly is a profile presented, and what does that lead time cover?
A good answer
A defined lead time: a vetted profile, not just a CV.
Red flag
A different lead time depending on the page or the contact person.
3
How are profiles selected?
A good answer
Co-optation or a validation process, a minimum level of experience, documented checks.
Red flag
A catalog with no entry criteria.
4
Who is accountable for the result, and what does the contract say?
A good answer
A written scope, deliverables and accountability.
Red flag
Verbal promises.
5
How does the provider work with my legal, HR, IT and integrator?
A good answer
A defined role in the governance and the backward plan.
Red flag
An engagement limited to a single workstream when the project has four.
6
What happens if the separation date slips or the TSA is extended?
A good answer
A review of the plan and resources, planned from signing.
Red flag
No provision: the contract assumes everything goes as planned at the Deal.
What FocusTribes says on these points
FocusTribes is a selective community of independent consultants: they are identified through co-optation (by clients or consultants), accredited through a strict validation process, have at least 8 years of hands-on experience, and most come from large consulting firms. The community counts more than 1,000 consultants and FocusTribes identifies the right profile within 48 h. On accountability for the result and on date slippage, ask questions 4 and 6 in writing before signing: the standard is the same for all providers.

FAQ: carve-out support and post-merger integration
Q.
Which firms or freelance consultant networks can support a carve-out or post-merger integration?
There is no reliable ranking by name. Four types of players share the field: M&A advisory firms, IT services firms and integrators, matching platforms and selective communities of independent consultants such as FocusTribes. The right choice depends on what needs to be executed, how fast they can be mobilized and what the contract guarantees.
Q.
What is the difference between a carve-in and a carve-out?
A carve-out is the sale by a company of a branch of its business; a carve-in is the opposite operation, which consists of absorbing a business. The milestones are the same (Deal, Day 1 Readiness, TSA execution, TSA exit), but the seller's effort falls mainly on the first two, the buyer's on the last two.
Q.
What is a TSA and how long does it last?
A TSA (Transition Service Agreement) frames the period during which the seller provides services to the buyer to ensure business continuity. Its duration is set in the sale agreement; we have no reliable average duration to give, because it is negotiated deal by deal.
Q.
When should you bring in an independent consultant?
From the Deal, to set the schedule and the separation date, which drive the entire project. A full-time dedicated Program Manager then steers the roadmap and coordinates the business, IT and legal teams.
Q.
Do you need a full-time dedicated Program Manager?
Yes, it is one of the key success factors of a carve-in or carve-out, along with sponsorship from the CFO and the CHRO. Unclear governance leads to a loss of steering, critical delays and misaligned trade-offs.
Q.
Can a freelance consultant lead a carve-in?
Yes. At Shiftmove, a freelance program director from the FocusTribes community coordinated the integration of Optimum: ERP migration, HR contracts, payroll, cloud provider and vehicle fleet, with reporting to top management.
Q.
What are the main risks of a poorly anticipated carve-out?
A disruptive project can become conflict-ridden if it is not anticipated. The identified risks are unclear governance, lack of team availability, a poorly aligned schedule, poor IT anticipation and a lack of change management support.
A carve-out is not won on the provider's name, but on the separation date set at the Deal, on the four workstreams run in parallel and on the profile who steers it all. If you compare us, apply the same grid to us.
