How to Ensure a Smooth M&A Process for Your Agency
Most agency M&A processes that fail or underperform do so for predictable, avoidable reasons. The causes almost never appear in the deal structuring phase they are embedded in process design decisions made early, in preparation quality, and in how both parties manage the human dynamics that make agency transactions structurally different from other service business acquisitions.
A smooth process is not one without problems. It is one where problems are identified and addressed at the appropriate stage rather than discovered late when they have become deal-killers.
Front-Loading the Work That Kills Deals Late
The most effective thing both buyers and sellers can do to ensure process quality is to compress the time between problem discovery and problem resolution. This means doing preparation work thoroughly before the process begins.
For sellers, this means getting your financial house in order before going to market. A clean, GAAP-consistent set of accounts with normalisation adjustments fully documented owner compensation, non-recurring items, related-party transactions is the foundation of a credible process. Sellers who produce this documentation for the first time under buyer scrutiny, when time pressure is high and deal psychology has created stakes on both sides, will produce it more slowly and less accurately than if it were prepared in advance.
The specific documents that derail agency deals most frequently when produced late:
Client schedules that show revenue concentration more clearly than summary financials
Historical revenue split by retainer versus project (most agencies have not calculated this before being asked)
Employee agreements that contain unexpected restrictive covenants, vesting rights, or deferred compensation obligations
Lease agreements with assignment clauses that require landlord consent to change of ownership
IP ownership documentation for creative work, brand assets, or software tools that the agency has developed
Identifying and resolving these issues in a pre-deal preparation phase takes significantly less time than doing so under due diligence pressure.
For buyers, the equivalent front-loading is investment committee alignment before committing significant process time. A buyer who enters an LOI without a clear internal understanding of what they are willing to pay, under what conditions, and with what deal structure preferences will produce a messy negotiation on those points later. Investment committee surprises during exclusivity "we need a larger earnout than we discussed" or "the committee wants a lower upfront payment" are among the most common causes of deal fatigue and failed transactions.
Managing the Due Diligence Phase
Due diligence in an agency acquisition covers three areas that are relatively standard across M&A, and two that are genuinely agency-specific.
The standard areas financial due diligence, legal due diligence, tax due diligence do not need special design for agency transactions. They should be run professionally with experienced advisers. The main process risk is timing: allowing these workstreams to run sequentially rather than in parallel, or failing to resource them adequately, extends timelines unnecessarily and creates deal fatigue on both sides.
The agency-specific areas are more important to get right.
Commercial due diligence. The core question in agency commercial DD is whether the revenue will persist after the transaction. This requires direct assessment of client relationship quality not just client retention rates as reported by the seller, but the underlying dynamics of those relationships. How many contacts does the agency have at each major client? Are those contacts at the right seniority level to be decision-makers if the agency's ownership changes? Is the agency on client procurement frameworks that will require re-tendering?
People due diligence. Agency value sits primarily in people. A DD process that reviews employment contracts but does not assess the stability, motivations, and transition risk of key employees is incomplete. For any employee who could affect client relationships, capability delivery, or the management of the business post-acquisition, the buyer needs an informed view on their likely behaviour after close and ideally, a retention strategy agreed before the transaction completes.
Communication and Stakeholder Management
Process failures that stem from poor communication are entirely avoidable, but they are common.
On the buyer side, the most frequent communication failure is over-lawyering. When legal language and structuring complexity is allowed to dominate correspondence in a way that obscures the commercial intent of terms, sellers become defensive and negotiations become positional rather than problem-solving. Buyers who can articulate the commercial rationale for deal terms clearly "we are asking for this warranty because we are concerned about X, and here is why" navigate negotiations more efficiently than those who allow lawyers to lead on commercial points.
On the seller side, the most frequent failure is inconsistency. A seller who gives different answers to the same question in different conversations with buyers, advisers, and their own management team creates trust issues that take disproportionate time to resolve. All factual representations about the business should flow from a single authoritative set of documents, and the seller should be comfortable presenting those documents consistently under detailed questioning.
The employee communication timing issue is among the most consequential in agency deals. Employees who discover a transaction from an unofficial source, before the acquirer is ready to present a retention plan and a coherent ownership narrative, will draw their own conclusions — and those conclusions are rarely optimistic. The buyer and seller should agree on the employee communication plan before exclusivity is signed, not as an afterthought on the day of close.
What Agencies.co Observes
Among the transactions we have visibility into through our platform and the agencies in our owner-enriched database, the process variable that most consistently correlates with deal completion versus failure is timeline management. Deals that lose momentum where the buyer's response time to due diligence queries slows, where scheduled calls are repeatedly rescheduled, where the next stage does not begin for weeks after the previous one closes have a significantly higher rate of failure than those that maintain consistent forward momentum.
This is partly a practical observation about deal psychology: both parties sustain deal enthusiasm more easily when progress is visible and deadlines are respected. It is also structural: the longer a due diligence process runs, the more opportunities there are for something to go wrong in the underlying business that affects the transaction.
Practical Implications
Define a process timeline before you begin, with specific deadlines for each phase — NDA, information memorandum distribution, first-round indications, management presentations, final offers, exclusivity, due diligence completion, close. Both parties should agree to this timeline at the outset and hold each other to it.
Designate a single point of contact on both sides for all day-to-day process communication. Nothing slows a deal down more than queries being routed through multiple people with different levels of information and different response timelines.
Agree on the data room structure and content before it is populated. A data room that is half-complete, disorganised, or contains unverified information will generate extended back-and-forth that delays the due diligence phase unnecessarily.
Separate commercial negotiation from legal drafting. The commercial terms of a deal should be agreed at heads of terms stage, with sufficient specificity that there are no material open points. The legal documentation phase should give effect to agreed commercial terms, not be used to relitigate them.
Do not underestimate the people dimension. In a manufacturing business, the assets are the plant and equipment. In an agency, the assets go home at the end of the day. A process that treats employee retention as a box to check will produce employee outcomes that reflect that.
