Two Things Every OCG Needs to Actually Work: Trained People and a System That Reads
Custodia Advisory | Private Equity | Outside Counsel Guidelines & Procurement Team Training
A well-drafted Outside Counsel Guideline is a necessary starting point. It is not, on its own, a control. A guideline only does its job once two things exist alongside it: a procurement and audit team trained to actually apply it, and a contract and guideline management (CGM) system capable of reading incoming invoices — legal and fiduciary alike — against what that guideline actually says. Most platforms have the document. Fewer have built either of the two things that make the document mean anything.
Why training the team matters more than the document itself
An OCG is only as strong as the person reviewing the invoice against it. We've written before about why the people managing a long-standing outside counsel or fiduciary relationship are often the ones least equipped to catch drift — not through negligence, but because years of familiarity with a provider quietly erode the instinct to check a current invoice against the original agreement rather than against last year's bill, which starts to feel like the reasonable baseline.
Training procurement and audit teams to push back is a specific, learnable skill, not a personality trait some people happen to have and others don't. It means teaching a reviewer to treat "this looks broadly similar to what we usually pay" as an insufficient standard, and to instead ask a sharper question every time: does this invoice match the rate, the cap, the billing format, and the entity-level detail the governing agreement actually specifies? It means giving reviewers explicit permission — and backing — to reject or query an invoice from a long-standing provider, rather than deferring to the relationship's history as a stand-in for the invoice's accuracy. And it means building a habit of comparing against the agreement itself, not against precedent, since precedent is exactly how a 5% cap quietly becomes a 160% increase over enough renewal cycles.
None of this requires an adversarial relationship with outside counsel or fiduciary providers. It requires a team that has been taught, deliberately, what compliant billing actually looks like, and given the confidence to say so when an invoice doesn't meet that standard.
Where CGM systems come in
Training solves the human half of the problem. It doesn't solve the volume half. A platform receiving invoices across dozens of entities, multiple legal matters, and several fiduciary providers cannot rely on manual, invoice-by-invoice comparison against the OCG as its only line of defence — there's simply too much volume for a trained team to catch everything by hand, every time.
This is where a properly implemented CGM system earns its place. Done well, it reads incoming invoices against the guideline programmatically: flagging a rate that exceeds the agreed cap, catching a fee increase that breaches an annual escalation limit, identifying block-billed or vaguely described line items that don't meet the OCG's itemization standard, and surfacing entity-level detail gaps before an invoice is approved for payment. It applies the same rule, consistently, to every invoice that comes through — legal and fiduciary — without the fatigue or familiarity that erodes a human reviewer's scrutiny over time.
It's worth being precise about what this technology actually does, because we've written before about its limits. A CGM system flags. It does not negotiate, and it does not decide. The flag it raises still needs a trained person to pick it up, understand why it matters, and actually have the conversation with the provider that gets the fee corrected. Technology without a trained team to act on what it surfaces produces a very efficient list of unresolved problems. A trained team without technology to support them at volume misses things simply because there's too much to review by hand. The two are not alternatives to each other — they're the two halves of the same control.
Why this matters more as teams grow across the globe
The case for a CGM system gets stronger, not weaker, as a platform's procurement and audit function grows across multiple offices and time zones. A single, centralized team reviewing invoices by hand can at least rely on shared context and a consistent, informal sense of what "normal" looks like for a given provider. That informal consistency breaks down the moment invoice review is spread across teams in different regions, working different hours, with different levels of familiarity with any given provider relationship. Without a system applying the same rule set uniformly regardless of who's reviewing an invoice or where they're sitting, growing teams risk introducing exactly the kind of inconsistency that lets a non-compliant invoice slip through in one office while it would have been caught in another. A properly configured CGM system removes that variability — the rule is the rule, applied the same way everywhere, which becomes essential rather than optional once a platform's review function is no longer a single team in a single room.
What implementation actually looks like
Bringing both pieces together, in practice, means:
- Configuring the CGM system against the actual OCG, not a generic rule set — rate caps, escalation limits, entity-level itemization requirements, and prohibited charge categories specific to your guideline, applied consistently across legal and fiduciary invoices alike.
- Training procurement and audit teams on how to interpret and act on what the system flags, not just how to use the software — the skill sits in knowing what to do with a flagged invoice, not in operating the interface.
- Establishing a clear escalation path for flagged invoices, so a system-identified anomaly reliably reaches someone with the standing and mandate to resolve it, rather than sitting unactioned in a queue.
- Reviewing both the system's rule set and the team's practical judgement periodically, since OCGs themselves should be revisited over time, and a system or team calibrated to an outdated guideline will faithfully enforce the wrong standard.
The combination is the control
A platform with a strong OCG, an untrained team, and no supporting technology is relying entirely on individual vigilance, invoice by invoice, indefinitely — a standard that erodes predictably over time. A platform with sophisticated CGM technology and no trained team to act on its output has built an expensive detection system that documents problems without solving them. Only the combination — people who know what to look for, and technology that makes sure nothing gets missed at volume — actually turns a well-drafted guideline into a genuine, defensible control.
