7 Signs Your GBS Vendor
Relationship Needs an
Independent Audit

A contract renewal is a moment of consequential decision-making. You are either re-contracting on similar terms because the relationship has delivered well, renegotiating because you have learned something, or making a structural change because it hasn't worked. Each of those paths requires a clear, independent view of what the vendor has actually delivered against the original commitment.

Most organisations arrive at a renewal without that view. Performance discussions have been relationship-led. The SLA dashboard shows green — but reflects the metrics that are reported, not necessarily the full picture. There is no objective baseline from which to negotiate. Renewing in that position is not just commercially suboptimal. It locks in whatever gaps have accumulated and starts the next cycle from imperfect ground.

Cost growth in GBS outsourcing relationships is not always driven by scope growth. Individual decisions — escalation adjustments, approved change orders, pricing modifications — that each seemed reasonable at the time can aggregate into a material increase that was never sanctioned as a whole.

If GBS vendor spend has grown significantly over the past two to three years and the delivered scope has not grown commensurately, that gap warrants examination. The question is not whether costs have risen. It is whether the drivers of that increase are legitimate, documented, and proportionate — and whether they would survive scrutiny.

GBS performance reporting captures what is measurable. It rarely captures the more telling signals — responsiveness, judgment quality, whether the vendor is genuinely invested in outcomes or optimising for metrics. When business stakeholders consistently describe a vendor as difficult to work with, slow, or under-resourced, but those concerns never appear in the formal dashboard, that gap is itself meaningful.

It suggests either that the SLA framework is not measuring what actually matters, or that there is a divergence between what the vendor reports and what it actually delivers. Either is worth understanding — and neither is visible without someone willing to look beyond the dashboard.

When a new CFO, COO, or GBS Head joins with a significant outsourcing relationship already in place, they typically inherit the assessment of their predecessor — which means inheriting its blind spots too. The natural caution about disrupting a relationship that appears to be functioning means the independent moment — the one clean window to look at things fresh — passes without being used.

An independent review shortly after a leadership transition is not a vote of no confidence in the vendor. It is about building a baseline the new leader actually owns, rather than managing a relationship on assumptions they did not form and cannot fully interrogate.

Boards and HQ finance functions are asking harder questions about outsourcing relationships than they were five years ago — and the questions are increasingly specific. Whether the vendor is delivering against contracted headcount. Whether rates reflect the current market. Whether financial entitlements under the contract are being exercised. What the exposure looks like if the relationship needed to change.

If a rigorous review were commissioned tomorrow, would you be comfortable with what it found? If the honest answer is "I'm not sure," that uncertainty is itself an answer — and it is more usefully resolved on your own terms than under the pressure of an externally driven process.

In most GBS outsourcing arrangements, headcount is the single largest cost driver — and in most arrangements, the only evidence of that headcount is the vendor's own reporting. No independent verification mechanism exists. No process distinguishes between people genuinely dedicated to your account and those who are partially or nominally allocated.

This is not an accusation. It is a structural reality of how most GBS contracts are written and managed. The client's visibility ends at the invoice. What sits behind that invoice — whether the contracted capacity is actually present, productive, and genuinely allocated — is rarely examined.

Where independent verification has been conducted, the gap between contracted headcount and verifiable capacity is a consistent finding. It is rarely dramatic on any individual person. Across a relationship of meaningful scale, it aggregates into material exposure.

Three years is roughly the point at which a GBS outsourcing relationship, if it has not been independently reviewed, tends to have accumulated enough change — in scope, in personnel, in market benchmarks — that the gap between the original agreement and the current reality has become structural rather than incidental.

Contract terms written in year one reflect assumptions about the market, the vendor's cost base, and the scope of services that may no longer be accurate. Rate benchmarks from the original negotiation may be materially above or below the current market. Governance mechanisms designed at inception may have drifted into informality. None of these are necessarily vendor failings — they are the natural consequences of time passing without a structured review.

The absence of prior review is not itself a sign of a poor relationship. It is a sign that the organisation does not yet have a verified view of where it stands. That view is always worth having — and the longer it is deferred, the more it tends to cost when eventually obtained.
