BOTTOM LINE UPFRONT
European PE-backed finance functions are often stitched together deal by deal, with no deliberate design behind them. Fixing that means mapping activities first, then choosing the right structure — captive SSC, BPO, or hybrid — before simplifying and moving, with the CFOs who act first landing a cleaner story at exit.
Eight considerations for getting shared services and outsourcing right across a European footprint
Sixty percent. That is how much time the average PE-backed finance function spends collecting data. Not analysing it. Not acting on it. Collecting it. Sponsors and CFOs want that number below 20% and the freed capacity redirected toward business partnering and decision support. The answer, increasingly, is structural: a shared service centre (SSC), a BPO arrangement, or some combination of both. The functions that have not made that move were not built badly. They were never really built at all. They accumulated deal by deal: an acquisition in Germany, a legacy team in Amsterdam, an operating model that made sense a decade ago and was never revisited.
Across medium-sized European portfolios (EUR 500m to 2bn), finance as a percentage of revenue runs at 1.5% to 2% or higher. Top-quartile organisations operating with centralised, well-designed finance functions run at half that, a gap that comes down to deliberate structural design rather than headcount management. That means simplified processes, a strategic view of what the function should own versus centralise versus transfer to a third party, and a location strategy that reflects that logic. Redesigning the operating model requires getting a sequence of decisions right. Each one shapes the value of the ones that follow.
Here are eight considerations for CFOs and operating partners before they start.
1. The right model is a function of size
Most PE-backed finance functions are not choosing between an SSC and a BPO. They are starting from a decentralised in-house model built up deal by deal and deciding whether to restructure it at all, and if so, how. The answer increasingly is that staying put is the most expensive option, even when it does not feel that way.
Scale determines the starting point. At smaller scale, BPO is almost always the faster and more capital-efficient path to centralisation than building a captive. The brand and infrastructure required to attract SSC-calibre talent in a competitive European location is hard to justify below a certain threshold. At larger scale, the calculus shifts. Volume supports a captive, scope can expand across functions over time, and at sufficient scale, the long-term economics of a captive model can outperform outsourcing, particularly where the organisation retains flexibility to expand scope across functions over the hold period.
European portfolios have arrived at this question roughly a decade after it became standard practice in North America. The structural barriers were real: cross-border complexity, language requirements, local labour law variation. What has changed is the economics. Those factors have not disappeared, but AI and modern shared service infrastructure have made centralisation more viable than it has ever been, at any scale.
2. The activity map comes before the model decision
Before any model decision gets made, the service delivery map needs to be defined: what stays local, what centralises, what moves offshore, and what the business needs to own to stay competitive. That map is the input that determines whether BPO, captive, or hybrid is the right answer. It is not a step a BPO provider completes on your behalf. Organisations that skip this end up with unclear scope, extended timelines, and blurred accountability across the finance function. The operating model follows the service activities. Reversing that sequence is expensive.
3. Simplify before you move
This is where most transformations leave money on the table before they have even started. Moving a broken process to a cheaper location does not fix it. Simplifying it does: eliminating low-value variation, documenting the process as it will run post-transition, and putting stage-gate governance and an automation roadmap in place.
For organisations pursuing a captive model, the discipline of simplification before transition is particularly consequential. BPO providers typically absorb some process remediation as part of onboarding, but the captive path does not offer that buffer. A function that arrives at transition with documented SOPs, proper stage-gate governance, and a clean automation roadmap is a categorically different project than one that does not. For captive builds, get the sequencing right before you move. Automate as the new operating model stabilises. Organisations that get the order right consistently outperform those that do not.
4. AI improves every version of the structural decision
Before any structural change, AI-enabled process improvement across reconciliations, AP matching, accruals, and close activities typically delivers more than 10% cost reduction on the finance function cost base, regardless of the downstream model chosen. The model decision still comes down to size, control, and strategic fit. What AI changes is the economics of whichever path the organisation takes. A function that arrives at an RFP with documented, standardised processes and a clear automation roadmap negotiates from a fundamentally different position than one that ships its current state to a vendor and hopes for improvement. That includes how the BPO/SSC decision itself gets negotiated: organisations should size the opportunity and structure contract terms with providers around the automation upside, not treat AI and outsourcing as separate levers.
5. The model decision is a strategic fit question
A captive shared service centre makes sense when the sponsor values control, when the organisation has ambition to expand scope across functions over time, and when scale justifies the investment. A well-run SSC in Krakow, Lisbon, or Glasgow can deliver 20 to 30% cost reduction against a decentralised in-house model and builds something durable across the hold period. BPO makes sense when speed is the priority, when scale is smaller, or when the organisation lacks the brand depth to attract and retain SSC-calibre talent. Well-negotiated BPO arrangements deliver 30 to 40% cost reduction against the same decentralised in-house baseline, with providers absorbing capital expenditure and transition risk. The higher near-term savings from BPO reflect providers absorbing transition costs and efficiency risk upfront. The SSC case is a longer-duration argument: lower initial reduction, but compounding improvement and retained capability value at exit.
Many organisations land in a hybrid, which is often the most rational answer. A hybrid typically means retaining higher-complexity, judgment-intensive activities, such as FP&A, business partnering, and controls oversight, in a captive centre while routing transactional volume through a BPO provider. The structure lets organisations capture near-term outsourcing economics without ceding control over the activities that matter most to the business and to buyers at exit. The question is not which model is better in the abstract. It is which model fits this organisation, at this scale, with this sponsor’s strategic intent.
6. The retained organisation needs as much design rigour as the outsourced piece
Most transformations underinvest here and pay for it later. The retained function owns policy and controls, manages provider relationships and SLAs, handles exception escalation, and serves as the business-facing finance partner. It owns analytics and KPI interpretation.
Getting this right also means investing in the leadership and support infrastructure around it: the HR, IT, and capability development resources that allow the team to keep improving rather than just maintaining. Underinvest in the retained organisation and you get shadow organisations: pockets of duplicated work springing up elsewhere in the business to fill the capacity the retained function should have covered. And there is no internal muscle when something goes wrong mid-hold. Something always goes wrong mid-hold.
7. The business case has grown beyond salary arbitrage
Most sponsors anchor on AP, AR, and transactional accounting, where the volumes are visible and the automation case is obvious. The larger opportunity is in consolidation and reporting. Organisations that scope FP&A from day one realise meaningfully more value than those that treat it as a Phase 2 consideration. Transactional centralisation without redesigning how insight gets produced leaves the highest-value activities running on the same broken infrastructure as before.
One recent engagement moved month-end close from twelve days to seven, took on-time statement delivery from 67% to 99%, and reduced outsourced resources by roughly 35%. That kind of result gives buyers less to argue about in diligence. Quality-of-earnings reviews scrutinise add-backs and standalone-cost adjustments, and a function still running on outsourced volume and manual workarounds invites more of both. A function that has already centralised and automated presents a cleaner baseline, with fewer normalisation arguments and less standalone-cost risk for the buyer to underwrite. Sophisticated buyers price that difference at exit, and the discount compounds for businesses built deal by deal, where each acquisition kept its own back office instead of folding into one. The buyer inherits whatever integration work never got done.
8. The CFO who waits for the sponsor to ask is already behind
Operating partners across European portfolios are increasingly focused on finance operating model as a value creation lever, particularly where margin expansion is the thesis. The CFO who arrives with a point of view on activity placement, model options, and a sequenced roadmap is in a stronger position than one who responds to the question after it has been asked. The operating model is a value creation decision. It belongs in the same conversation as commercial strategy and capital structure.
European PE-backed businesses are not late to this conversation. They are arriving at it with better tools, cleaner benchmarks, and a technology layer that makes centralisation viable at scales that would not have supported it five years ago. The organisations that use the hold period to get the operating model right will be measurably better assets when it matters most. The ones that wait will spend that time explaining why they did not.
