# What Is Transition Services Agreement?

> A transition services agreement (TSA) is a post-acquisition contract where the seller provides specified services — IT, finance, HR, operations — to the buyer for a limited period while the business integrates.

**A transition services agreement (TSA)** defines how the seller supports the buyer after closing — for a fee and fixed term — while acquired operations migrate to the buyer's systems.

### How it works

Typical TSA services: ERP and billing continuity, payroll processing, benefits administration, cloud hosting, customer support queues, and regulatory filings. Schedules list service level, duration (often 6–24 months), pricing (cost-plus or fixed fee), and termination triggers. [Carve-out](/glossary/carve-out) deals rely heavily on TSAs when a division separates from parent infrastructure — see also [carve-out TSA](/glossary/carve-out-tsa).

Startup [trade sales](/glossary/trade-sale) may include lightweight TSAs if product runs on seller AWS accounts or if founders provide engineering transition. Misaligned incentives arise when seller teams want to wind down quickly but buyer integration lags.

Legal teams separate TSA from employment agreements and consulting SOWs to clarify liability and data handling.

### Why it matters

- **Founders:** TSAs can trap key engineers in low-value maintenance instead of new roles. Negotiate headcount caps and hard sunset dates.
- **Investors:** Extended TSAs delay cost synergies buyers modeled — earn-out disputes sometimes trace to TSA failures.

### Common mistake

Signing open-ended TSAs without migration milestones. Buyers defer painful integration; sellers absorb open-ended cost and distraction.

## FAQ

### What is transition services agreement in simple terms?

A TSA is a temporary help desk after a sale — the old company runs payroll, servers, or accounting for the buyer while they stand up their own systems. It has a end date and a fee schedule.

### Why does transition services agreement matter?

Poorly scoped TSAs delay integration and burn seller team attention. Buyers price TSAs into deal models; sellers negotiate cost recovery and exit milestones.
