Our services
Interim management
An increase in activity, a project or the departure of a member of your team are all events that may require you to strengthen your team, whether for a few days, a few weeks or even several months.
Benefit from readily available talented professionals to support or augment your teams.
Partner selection & project management
Success starts with having the right partners.
Cash management, trade finance or your Treasury Management System are critical and require the use of the right partner.
After a detailed analysis of your needs, volumes and strategy, we’ll help you choose the right partner to make your day-to-day life easier and support you through to deployment.
Audit, consulting, training
Your teams are focused on many day-to-day tasks and ongoing projects. They don’t always have the time to question their practices, processes and the tools they use.
Let us bring a fresh perspective to your organisation by taking stock, making real recommendations for operational excellence, helping to implement them and regularly evaluating their impact.
We can also train your teams on some concepts (cash pooling, etc.), techniques (hedging, etc.), standards (ISO20022, etc.), systems (Diapason, Kyriba, Sage, etc.)
