Operational Support: Boost Your Efficiency with Winston Advisory

At Winston Advisory, we understand that there are critical moments when your Finance, Accounting, Controlling, or Consolidation teams are under pressure: closing periods, budgeting, reporting… That’s why we created our Operational Support offer.

What is an Operational Support intervention?

It’s a targeted, temporary reinforcement for your teams.
We provide experienced consultants, part-time or full-time, to:

  • Increase your bandwidth during peak activity periods.
  • Bring specialized expertise to accelerate your projects.
  • Optimize your processes using tools like Power Query in Excel to automate data processing.

In short: you save time, secure your deliverables, and improve your practices for the long term.

When should you call on an external consultant?

Our clients typically reach out to us for:

  • Facilitating closing activities (monthly, quarterly, annual).
  • Speeding up the budgeting process and ensuring forecast reliability.
  • Sharing clear performance indicators with business teams.

How is this different from hiring a temporary employee or intern?

A Winston Advisory consultant is more than just extra hands:

  • They bring immediate expertise and strategic perspective.
  • They implement long-term solutions (automation, data reliability).
  • They deliver impact from day one, without lengthy onboarding.

In summary:

With Winston Advisory, you turn peak activity periods into opportunities for sustainable improvement.
