Quick answer: A preparation engagement readies the business for sale through a readiness review, earnings normalization, projections and a memorandum, and ends before buyers are contacted. A full sell-side mandate runs the entire process through closing. A modular engagement links the two with decision points. The right choice depends on how ready the business is, how firmly the owner has decided to sell and how much of the process the owner wants to hand over.
Key points
- A preparation engagement readies the business and ends before buyers are contacted. A full mandate runs the sale through closing. A modular engagement links the two with decision points.
- The right structure depends on readiness, on how firmly the owner has decided to sell and on how much of the process the owner wants to hand over.
- Moving between structures works when the agreement settles ownership of the work product, fee credits and when exclusivity and any tail begin.
- An advisor expecting to run the sale may lean toward launching sooner, and a preparation-only advisor may lean toward more preparation. Ask for the readiness criteria in writing.
Three ways to structure a sell-side engagement
Sell-side engagements differ in scope, in who runs the sale and in who carries the risk of no deal. A preparation-only engagement covers readiness work and ends before the market is approached. A full sell-side mandate has the advisor run the whole process through closing. A modular engagement sits between them: defined modules in sequence, each with its own scope and a decision point where the owner can stop or continue. The choice depends on how ready the business is, how firmly the owner has decided to sell and how much of the process the owner wants to hand over.
| Preparation-only engagement | Modular engagement | Full sell-side mandate | |
|---|---|---|---|
| Scope | Readiness review, earnings normalization, projections, memorandum and a buyer strategy | Defined modules in sequence, such as preparation, launch and first round, then negotiation and closing | Preparation, marketing, buyer outreach, negotiation, diligence coordination and closing |
| Where it ends | When the materials are delivered and the owner decides whether to launch | At the end of each module, unless the owner approves the next | At closing, or at termination under the agreement |
| Who contacts buyers | The owner, or a later advisor | The advisor, once the launch module is approved | The advisor |
| Fee shape | Usually fees for the defined work, not tied to a sale | Fees by module, with a success fee often attached to the final module | Usually a mix of upfront or recurring fees and a success fee |
| Owner’s commitment | Commits to the preparation work only | Commits one module at a time | Commits to a process, usually with exclusivity and a tail |
| Main risk | Work is done and the sale never launches, or launches with someone else | Handoff gaps and scope disputes between modules | Being tied to an advisor that is not performing, if termination terms are weak |
| Fits when | The business is not yet ready, or the owner is undecided | The owner wants to test fit and readiness before committing, or wants cost staged | The business is ready, the owner has decided to sell and wants a managed, competitive process |

Which situation fits which structure
Preparation only. The signals are records kept on a cash basis, adjustments the owner cannot support, heavy reliance on the owner, a customer that supplies much of the revenue, or an owner who has not decided to sell. In each case the first need is to learn what a buyer would conclude, and to fix what can be fixed. The sale readiness scorecard shows where a business stands, and the guide to timing a sale covers the personal side of the decision.
Modular. The signals are an owner who wants senior help but is not sure of the timeline, who wants to see an advisor’s work before committing the whole process, or who has received an inbound approach and needs to understand it before responding. Staging also suits a business near the edge of what advisors take on, as the guide on whether a business is too small for an M&A advisor explains.
Full mandate. The signals are a business with supportable earnings and a clean data room, an owner who has decided to sell, buyers likely to compete, confidentiality that needs managing and an owner who cannot run both the business and a process. A deal structure with an earnout, rollover equity or a seller note also favors one party carrying the whole process, because the terms interact.
Moving from one structure to the next
Preparation work is only valuable if it carries into the next stage. A preparation engagement should end with a written conclusion, not a verbal impression. That conclusion states which adjustments are supported, which buyer types are likely, what issues remain and what each could cost in price or terms. The owner then chooses among three paths: stop, extend the preparation or launch.
Illustrative example: A modular engagement with three decision points
An owner is unsure whether to sell within the next year and has not had earnings reviewed by anyone with a buyer’s view. The engagement is scoped in three modules.
Module one covers a readiness review, normalized earnings and a draft memorandum. At its end, the advisor delivers a written view of which adjustments are supported, which buyer types are likely and what issues remain. The owner decides to stop, to extend preparation or to launch.
Module two covers the launch: a buyer list, outreach, first-round indications and management meetings. Exclusivity and a tail begin here and are tied to a written buyer list. At its end the owner decides whether any offer justifies a letter of intent.
Module three covers negotiation, diligence coordination and closing, and the success fee attaches to this module. The agreement credits fees paid for module one, lets the owner keep all work product if the engagement stops, and limits the tail to buyers on the written list.
The structure and terms are invented to show the mechanics and are not benchmarks of any firm’s engagement.
What carries over, and what changes, should be written down at the start. The work product, including the memorandum, the adjusted earnings schedule and any buyer list, should stay with the owner. Fees paid for earlier stages may or may not be credited against later ones. Exclusivity and the tail usually begin when the process launches, not when preparation begins, and the reading guide for engagement letters explains how each is drafted.
Incentives change with the structure
Each structure pushes the advisor toward a different recommendation, and the owner should know which way. An advisor who expects to run the sale may lean toward launching sooner, because a launch is where its larger engagement begins. An advisor paid only for preparation may lean toward more preparation, since additional work is what it is paid for. A full mandate with a large success fee aligns the advisor with closing, which is not always the owner’s best result.
None of this disqualifies an advisor. It is a reason to ask for the criteria in writing: the conditions under which the advisor would recommend waiting, the conditions under which it would recommend launching, and an example of a business it advised to wait. The guide to how M&A advisors are paid describes how each fee design shifts risk between owner and advisor.
Terms to settle before signing
- Whether the owner has decided to sell. An undecided owner is better served by a structure with a stopping point.
- Ownership of work product. The memorandum, the adjusted earnings schedule, the projections and the buyer list should belong to the owner if the engagement stops.
- Credits. Whether preparation fees reduce later fees when the owner proceeds.
- When exclusivity starts. A long exclusive right to market the business during a phase in which no buyer is contacted is a full mandate in everything but name.
- Tail. Which buyers it covers, and whether it applies if the owner stops after preparation.
- People. Which individuals do the work in each phase, and whether the same team continues if the owner proceeds.
- Gate criteria. What the advisor will deliver at the end of each stage so the owner can decide.
- Termination. The owner’s rights at each decision point, and what is owed when the owner stops.

Frequently asked questions
What is the difference between a preparation engagement and a full sell-side mandate?
A preparation engagement covers readiness work, such as normalizing earnings, building projections and writing the memorandum, and ends before buyers are contacted. A full sell-side mandate runs the whole sale through closing, including outreach and negotiation. The first prepares the owner to decide. The second carries out the decision.
Can an owner hire an advisor only for preparation?
Yes. Advisors can offer a preparation-only engagement, and the owner decides afterward whether to launch, wait or use another advisor. Settle in advance who owns the work product, whether preparation fees count as credit against a later mandate and whether the advisor has any right to run the sale.
Is a modular engagement better than a full mandate?
Neither is better in general. A modular structure lets the owner commit one stage at a time and stop at a decision point, at the cost of handoff gaps and more negotiation of each stage. A full mandate gives one party responsibility for the whole process and suits an owner who is ready and has decided to sell.
Does a preparation engagement lock the owner into the advisor?
It should not. The agreement should say that the owner keeps the work product, that any exclusivity starts only when a sale process launches, and that any tail covers only buyers on a written list. If a preparation agreement grants a long exclusive right to sell, an owner should read it as a full mandate and review it that way.
How does an owner know the business is ready to move from preparation to launch?
Ask the advisor for a written readiness conclusion: which adjustments are supported, which buyer types are likely, what issues remain and what each could cost in price or terms. The owner can compare that view with a readiness scorecard and with personal goals before deciding to launch.
Do preparation fees count toward a later success fee?
Only if the agreement says so. Some engagements credit preparation fees against later fees when the owner proceeds, and others do not. Ask for the rule in writing before the first payment, along with what happens to the work product if the owner chooses a different advisor.
