Ranges are typical, not quotes - the price for your job depends on scope and location, so always confirm with the provider.

What moves the price

Fees depend on deal size, structure, and complexity. A straightforward asset purchase usually requires less legal and financial diligence than a stock sale, merger, or transaction involving several entities, regulated operations, or international parties.

Advisers may charge hourly rates, a fixed fee, a monthly retainer, or a success fee tied to closing. Specialist experience, tight deadlines, location, and the amount of negotiation can also raise costs. Accounting, tax, valuation, and regulatory work may be billed separately.

How to keep the cost down

Define the scope before hiring, ask which services and expenses are included, and compare proposals on the same assumptions. Request a fee breakdown and clarify how charges change if the transaction stalls or does not close.

Use a focused diligence plan and share organized financial and legal records to reduce avoidable work. Collecting quotes through Reedleys means every number comes from a real, checked listing.

Price questions, answered

Do M&A advisers require a deposit?

Many request an upfront retainer or monthly minimum, while some charge mainly at closing. Confirm whether any retainer is credited against later fees and what happens if the deal ends early.

Why do M&A quotes differ so much?

Proposals may cover different work, staffing, and deal risks, and advisers use different fee structures. Compare the scope, exclusions, billing triggers, and experience rather than looking only at the headline fee.

Are legal and accounting costs included in an M&A fee?

Not always. Ask whether counsel, tax advice, financial diligence, valuation, data-room costs, and other third-party expenses are included or billed separately.
