Having worked with a number of consultancy founders who have been through PE processes, there’s a moment that almost all of them describe in similar terms. It’s the moment when they realise that the things they assumed were their most compelling assets, the quality of their work, the strength of their client relationships, the depth of their team’s expertise, are being taken as a baseline assumption rather than as differentiating factors. The buyers have already satisfied themselves on those points. What they’re actually interrogating is something different, something that tends to catch founders off-guard.
They’re looking for predictability. Specifically, they’re asking whether this business can reliably generate revenue without depending on the personal relationships and involvement of specific individuals, and whether the systems exist to demonstrate that reliably with data rather than narrative.
What commercial due diligence is actually stress-testing
By the time a private equity firm is in a room with you, they’ve already done the high-level market work. They understand whether your sector is attractive, whether your positioning makes sense and whether the broad commercial logic holds up. What commercial due diligence is really doing is something more uncomfortable: it’s testing whether the business behind the proposition is as solid as the proposition itself.
They want to understand where revenue actually comes from, and specifically whether it’s concentrated in a small number of relationships or distributed more broadly. They want to know whether revenue is recurring or transactional, and what the retention data actually shows. They want to see a defined pipeline process with credible forward visibility, not a vague sense that there are conversations happening. They want to understand the sales process in enough detail to assess whether it could continue to function if the founder stepped back. And they want data: conversion rates, average deal sizes, sales cycle lengths, win and loss patterns. Not estimates or directional comments, but actual numbers from a system that’s been maintained consistently over time.
Most consultancies at the point of a PE approach cannot answer these questions with genuine confidence. Not because the underlying business isn’t strong, but because the commercial infrastructure was never built to the standard that due diligence requires. The business grew on the strength of founder relationships and excellent delivery, and the sales function was never systematised because it never needed to be. In a PE context, that creates a problem: not necessarily a deal-breaker, but a gap that shows up in the risk assessment and ultimately in the valuation.
The difference between potential and predictability
Every founder walking into a PE process believes their business has significant headroom, and most of them are right. The question isn’t whether more growth is possible; the question is whether the business has the systems to capture that growth in a reliable and repeatable way. Potential is a claim. Predictability is a demonstration, and it has to be supported by evidence rather than conviction.
Predictability in a commercial context means several specific things: revenue that doesn’t depend on one or two individuals to generate it; a process for finding, qualifying and winning new business that multiple people follow and that produces consistent results; data that supports a credible forward view of revenue; and a track record of converting that forecast into reality over time. Consultancies that can demonstrate this tend to attract better terms, command higher multiples and move through due diligence more cleanly. The risk profile is genuinely lower when a buyer can see how the commercial engine works rather than having to trust that it does.
What sales maturity looks like from a buyer’s perspective
When a sophisticated buyer assesses commercial maturity, they’re looking for a specific set of indicators. Is there a documented sales process that multiple people follow, or does the process exist only in the founder’s head? Is the CRM maintained accurately and consistently, or is it a filing system for optimistic early-stage entries that never get updated? Is there pipeline visibility beyond the next thirty days, and does the forecast have a track record of being approximately right? Are there conversion metrics that have been measured over enough time to be meaningful? And critically: is there a culture in which business development is treated as a priority function, or is it something that happens around the edges of client delivery when people have capacity?
Most firms at the stage where PE interest becomes realistic have some of these elements but not all of them. The CRM might exist but the data quality might be poor. There might be a pipeline review process but no real forecasting. The dependency on the founder in commercial conversations might be significant even if it isn’t acknowledged. These gaps can be addressed, but they take time to fix properly, which is why the preparation timeline matters.
How better commercial infrastructure changes the negotiation
A firm we’ve worked with through a pre-PE preparation process is a good illustration of how this plays out in practice. Before we started working together, new business was almost entirely founder-driven, the CRM was inconsistently used and there was no formal pipeline review process. Over eighteen months, they built a documented sales process, established a weekly commercial rhythm, improved their CRM data quality substantially and produced their first meaningful revenue forecast. When they went to market, the due diligence process was significantly cleaner than it would have been, the conversation about business risk was shorter because the evidence existed to answer the questions, and the outcome reflected that.
The comparison is typically between a business where the commercial function is visible, documented and evidenced, and one where it’s strong but opaque. The opaque business may be just as good in practice, but it commands a higher risk discount because the buyer has to take more on faith.
What to do with this
If a PE event or even a trade sale is a realistic possibility within the next two to five years, the right time to start building commercial infrastructure is now, not six months before you go to market. The reason is straightforward: you need time to build a track record, not just a process. A well-configured CRM and a documented methodology are helpful, but what due diligence really wants to see is eighteen months or more of consistent data showing the system actually working. Forecasts made and approximately met. Pipeline metrics moving in a positive direction. Conversion rates that have been measured long enough to be credible.
The practical starting point is an honest audit of where you are now: what does your commercial data actually show, what’s missing, and what would need to be true for a sophisticated buyer to feel confident about your revenue generation capability? That audit usually surfaces a clear list of priorities, and working through them methodically over the following year or two positions you very differently for whatever commercial conversation eventually comes next.
