This post covers what a business purchase agreement lawyer actually costs specifically for work on the purchase agreement document itself, and when in your acquisition timeline to bring one in.

  • Expect $1,500 to $5,000 specifically for purchase agreement review or drafting.
  • This can overlap with your general acquisition lawyer, but the fee is often itemized separately.
  • A flat fee for agreement review is common and often more predictable than hourly billing.
  • Skipping this step to save money is a false economy compared to what an unfavorable clause could cost later.

What Does This Specific Fee Cover?

Reviewing a seller-drafted purchase agreement, negotiating changes on your behalf, or drafting the agreement from scratch if you're the one proposing terms. This is narrower than a full acquisition legal engagement, which might also include due diligence support and closing coordination — some lawyers itemize purchase agreement work separately, which can make costs more predictable if that's the specific service you need.

How Much Should You Actually Expect to Pay?

Typically $1,500 to $5,000 for purchase agreement review or drafting on a small business deal, depending on the agreement's complexity and how much negotiation is involved. A straightforward asset purchase with terms already largely agreed lands toward the lower end; a deal with earnouts, seller financing, or unusual representations pushes toward the higher end. This is separate from, and typically smaller than, the full legal fees covered in our broader guide to buying a business lawyer.

When Should You Bring This Lawyer In?

Once you have a signed letter of intent and are moving toward drafting or reviewing the actual agreement — this is later in our 7-stage business acquisition process guide than your initial LOI negotiation, but before you're anywhere near signing. Bringing a lawyer in only after you've already agreed to specific contract language with the seller puts them in a much weaker negotiating position than reviewing draft language before anything is settled.

Is a Flat Fee or Hourly Rate Better?

A flat fee for purchase agreement review specifically gives you cost certainty and is common for straightforward deals — ask upfront whether your lawyer offers this option. Hourly billing makes more sense for a deal likely to require significant back-and-forth negotiation, since a flat fee in that scenario might not adequately compensate the lawyer for the actual time involved, which can create friction. Ask directly which model fits your specific deal's complexity.

What's the Real Cost of Skipping This?

Using a generic U.S. Small Business Administration's guide to buying an existing business-referenced template or a downloaded form without professional review risks missing protections specific to your deal — an earnout clause that doesn't actually protect you, or liability language that leaves you exposed to something uncovered during due diligence checklist for buying a business. The legal fee here is genuinely small compared to what a single missing clause can cost after closing, which is why skipping this step to save a few thousand dollars is one of the more common regrets buyers report.

What's the Difference Between Review and Drafting?

Reviewing a seller-drafted agreement is typically faster and cheaper, since the lawyer is checking and negotiating existing language rather than creating it from scratch — this is common when the seller's side proposes the first draft. Drafting from scratch, which makes sense if you're proposing terms first or the seller has no draft of their own, takes more time and generally costs more, since your lawyer is building every clause rather than reacting to someone else's. Ask which scenario applies to your deal before assuming a quoted fee range applies — a quote for review work doesn't necessarily hold if you actually need a full draft instead.

Should the Same Lawyer Handle Due Diligence Too?

Often yes, for continuity — a lawyer who's been reviewing documents during due diligence is already familiar with the deal's specific risks and can translate those findings directly into purchase agreement language without a separate lawyer needing to get up to speed from scratch. Some buyers do split the work between a due diligence specialist and a separate drafting attorney, but that split makes more sense for larger, more complex deals than for a typical small business acquisition, where continuity usually saves more time and money than it costs.

Whichever route you choose, confirm upfront who's responsible for coordinating with your lender on the loan documentation timeline — a purchase agreement finalized without that coordination can end up misaligned with your financing schedule, creating avoidable delays right before closing.
