The direct cost of manual contract review is visible on a billing statement: associate hours at a stated rate, organized by task. What is less visible is the cost that does not appear on any invoice. The review done at speed to meet a signing deadline that turns out to have missed a provision with post-closing consequences. The senior associate hours spent on structured reading that could have been applied to analysis. The inconsistency between two associates reviewing parallel purchase agreements in a portfolio acquisition, producing summaries that use different clause vocabulary and different flagging thresholds.
These are the costs worth examining if your team is thinking carefully about where legal spend in M&A review is actually going.
Where the Hours Go in a Purchase Agreement Review
A 180-page stock purchase agreement with disclosure schedules running another 80 pages is a typical document for a mid-market acquisition. Break down how attorney time is spent on that document and two categories of work emerge.
The first category is structured reading: identifying which clause category a given provision falls into, extracting the operative language for the indemnity cap, the basket type and threshold, the survival periods for different rep categories, the change-of-control consent requirements, the earnout mechanics if applicable. This work requires careful attention and accurate reading. It does not require the judgment of an experienced M&A practitioner. It requires a person who knows what to look for and can track defined terms across a complex document. For a document of this length, structured reading can occupy six to ten hours of associate time, depending on document complexity and how much cross-referencing is required to verify defined terms.
The second category is analysis: deciding whether the extracted terms are within market parameters for this deal size and sector, identifying which provisions require negotiation priority, flagging combinations of provisions that create unexpected exposure when read together, and advising the client on risk allocation decisions. This work does require experienced judgment. It cannot be systematized. It is the reason clients hire experienced transactional counsel and not just document processors.
The problem with current practice is that these two categories of work are not always clearly separated in how attorney time is allocated. Structured reading happens under conditions that make it more error-prone: late at night, under deadline pressure, without a consistent checklist, by whichever associate is available. Analysis happens after structured reading but is informed by whatever the structured reading produced. If the structured reading is incomplete or inconsistent, the analysis starts from a weaker foundation.
Inconsistency as a Hidden Quality Problem
A quality problem that is particularly difficult to see from outside the process is inconsistency in how structured reading is performed across different reviewers. Two associates reviewing materially similar purchase agreements, one for a target in a manufacturing acquisition and one for a software target in the same portfolio deal, will produce summaries that reflect their individual reading habits, clause vocabulary, and flagging thresholds.
This is not a competence problem. Both associates may be performing well by any individual standard. The problem is that comparing terms across multiple agreements in a portfolio acquisition, or tracking how a specific seller's positions compare across multiple deals over time, becomes difficult when the underlying reviews are not structured consistently.
For in-house teams managing multiple transactions, this inconsistency compounds. A general counsel who wants to understand how the company's indemnification exposure has evolved across four acquisitions in two years cannot easily draw on prior associate summaries if those summaries were produced without a consistent structure. The information exists in the files somewhere, but reconstructing it requires reading back through the underlying agreements rather than relying on the first-pass summaries.
The Timeline Pressure Problem
Purchase agreement review often happens under conditions that are structurally unfavorable for thorough work. The signing timeline is compressed. The document is received late in the day. The buyer's counsel and the in-house team are already working on multiple workstreams related to the same transaction.
Under these conditions, first-pass review tends to get time-compressed. An associate who would spend eight hours on structured reading in an unhurried environment spends four hours instead. The result is a summary that covers the most visible provisions but may miss provisions that appear in unusual locations in the document or that require careful reading of disclosure schedule exceptions to understand their effect.
The provisions most commonly missed under time pressure are not the ones that appear in obvious locations. Indemnity caps appear in a standard article and are easy to find. The provisions that get missed are those that modify the obvious ones from unexpected locations: a definition buried in the definitions article that narrows the scope of a rep, an exhibit that contains representations that are incorporated by reference into the main agreement body, a basket calculation that references a defined term that itself is defined by cross-reference to an attachment.
When First-Pass Quality Has Post-Closing Consequences
Most first-pass review is accurate enough that the missed provisions do not matter. The deal closes, the post-closing integration proceeds, and no one ever examines what the first-pass summary did or did not catch. But when a post-closing dispute arises, the quality of the first-pass review can become directly relevant.
Consider a scenario where a buyer discovers after closing that the target had a material customer contract containing a termination-for-convenience provision that the customer exercised post-closing. The question of whether the seller made accurate representations about the material contracts and their current status depends in part on what the contract contained, what the disclosure schedule disclosed about it, and whether the review team had a clear view of those provisions at signing.
This is not an argument that better first-pass review prevents all post-closing disputes. Many disputes arise from facts that cannot be known at signing regardless of review quality. The argument is narrower: a first-pass review that systematically surfaces material contract provisions, change-of-control requirements, and no-default reps creates a cleaner record of what was known at signing, which affects both the negotiation dynamic and any subsequent claim analysis.
Sizing the Opportunity
Quantifying these costs precisely is difficult because they show up in different places: attorney time billing, post-closing indemnification claims, integration surprises, and time spent reconstructing prior deal terms. But the structural argument is not complicated. Structured reading of a complex agreement is a high-cost task being performed by expensive professionals under suboptimal conditions. Any improvement in the accuracy and consistency of that structured reading has downstream value that exceeds its direct cost.
The practical case for reviewing how your team performs first-pass review is not that the current process is broken. For most transactions, it is good enough. The practical case is that "good enough" has a specific cost, and that cost is not always visible until it materializes in a context where it matters.
What Better Looks Like
Better first-pass review has a few specific characteristics: it covers a consistent set of clause categories across every agreement reviewed, it flags provisions in terms of what they actually say rather than what a particular associate expects to see, it surfaces disclosure schedule exceptions alongside the reps they qualify rather than treating them separately, and it produces output that senior counsel can work with directly rather than having to re-read to verify.
The means of achieving better first-pass review are secondary to understanding what it looks like. Whether your team improves it through process standardization, checklist discipline, review tooling, or some combination depends on the volume of agreements you review and the specific pressure points in your current process. The starting point is recognizing that the hidden costs of the current process are real costs, even when they do not appear on a billing statement.
