What Is a Transition Services Agreement?

What is a transition services agreement? It is a short term contract, usually called a TSA, under which the seller keeps running certain software, systems and services for a carved out or divested business after the deal closes. The carved out unit rarely has its own licenses and infrastructure on day one, so the TSA buys time to stand up a standalone estate. It is a bridge, not a destination, and the licensing risk inside it is one of the most underestimated parts of a carve out.

Why a transition services agreement exists

When a business is carved out of a larger parent, it often relies on shared software and systems that stay with the parent. On day one the carved out unit cannot simply keep using those licenses, because the entitlement belongs to the parent and many agreements restrict use to the parent organisation. A transition services agreement lets the seller continue providing those services for a defined period, giving the buyer time to procure its own licenses, migrate data, and build a standalone estate without an immediate operational gap.

The licensing risk inside a TSA

The hidden risk is that the seller right to provide software under a TSA is not unlimited. Many publisher agreements do not permit the parent to extend its licenses to a business it no longer owns, even temporarily. If the TSA assumes a continuation that the underlying license does not allow, both parties can be exposed to a compliance claim. A TSA that runs longer than planned compounds the risk, because the temporary arrangement quietly becomes the operating model while the clock on the underlying entitlement keeps running.

How buyers should manage a TSA

The goal is to exit the TSA on time with a fully licensed standalone estate. That means treating the TSA period as a project with a hard end date, mapping which services depend on which underlying licenses, and confirming that the seller is permitted to provide each one. Where a license cannot be extended, the buyer needs its own agreement in place before the TSA covers it. Sequencing this against the TSA end date is what prevents both an overrun and a stranded compliance gap.

What belongs in a TSA exit plan
Item	Question to answer	Risk if missed
Service inventory	Which services does the TSA cover	Gaps surface at exit
Underlying licenses	Is the seller permitted to provide each	Compliance claim against both
End date	When does each service stop	TSA overrun and extra fees
Standalone estate	What must the buyer license itself	Stranded gap at TSA end

Key takeaways

A transition services agreement is a temporary bridge while the buyer stands up its own software estate.
It is not a long term solution, and an overrun raises both cost and compliance risk.
The seller right to provide software under a TSA is often limited by the underlying licenses.
Exiting on time with a fully licensed estate is the only clean outcome.

Recommendations for buyers

Treat the TSA as a project with a hard end date. Plan the exit from the day the carve out closes.
Map services to underlying licenses. Confirm the seller is actually permitted to provide each service.
License the standalone estate in parallel. Have the buyer own agreements ready before the TSA stops covering each service.
Watch the clock. A TSA that overruns becomes the operating model and a quiet compliance exposure.

Frequently asked questions

How long does a transition services agreement last?

It varies, but a TSA is usually scoped for months rather than years. The aim is to keep it as short as the buyer needs to stand up its own licensed estate, because every extra month adds cost and risk.

Can a seller provide any software under a TSA?

Not always. Many publisher agreements do not permit the parent to extend its licenses to a business it no longer owns. The TSA scope has to be checked against what the underlying licenses actually allow.

What happens when a TSA ends?

The buyer must be running its own fully licensed standalone estate. If any service was not migrated and licensed in time, the buyer faces an operational gap or a compliance exposure at the exit date.

Is a TSA a licensing risk in a carve out?

Yes, and an underestimated one. The risk is that the temporary arrangement relies on entitlements the seller is not permitted to extend, exposing both parties to a claim if it runs unchecked.
