Why Grant Thornton

Traditional outsourcing can leave you feeling alienated or lacking in control. That’s why we put people first from the outset and give you a dedicated UK client manager so you can have confidence that you have an expert on hand working with and for your business.

Your client manager will handle everything, from ongoing review and improvement to ensuring smooth access and communication. We work with you to identify where outsourcing could help and to become a trusted extension of your team.

3.
The result:
We handed back a fully reconciled position and supporting schedules, giving the client's own finance team a clean, auditable baseline to report from.

    When to consider outsourcing

    You don't need to be struggling to benefit from outsourcing. Most clients come to us at one of these moments:

    • Growing into new markets.
      Expanding into a new region or jurisdiction means onboarding people and processes fast - outsourcing gets you there without the lead time of hiring in-house.
    • Scaling quickly.
      Rapid growth puts real strain on finance and payroll functions that were built for a smaller business.
    • Rising compliance complexity.
      Tax and reporting requirements shift constantly, and specialist local knowledge gets harder to maintain as you operate in more places.
    • After a merger or acquisition.
      A new entity needs a stable finance function and back-office fast, without disrupting the rest of the business.
    • Rising transaction costs.
      Working with a specialist partner under a clear service agreement often brings costs down and lifts efficiency, compared with scaling an in-house team.

    How we add value

    Every engagement is built on four commitments, whether you're outsourcing a single process or your entire finance function:

    • Named engagement lead. One point of contact manages your outsourcing relationship day to day, scaling the governance rhythm up or down as your priorities change.
    • Structured knowledge transfer. Before we take over any work, we document your current processes, data flows and controls, so the transition is fast and nothing is lost in handover.
    • Independent quality review. Every deliverable is checked by a qualified reviewer before it reaches you, with regular check-ins so small issues get caught early.
    • Outsourcing that scales with you. Whether you're a single entity or a multi-entity group, adding jurisdictions, going through an acquisition, or hitting a seasonal peak, our onshore and offshore delivery model flexes without disruption.

    We document checklists, procedures and work instructions for every activity, with your team's input at each step.
