HELP!!!!! cash management

Trident is an international advertising agency that has grown rapidly from a small base in Ireland. Key management and finance functions continue to be based in Dublin. The business now also has offices in the US, UK, France, Germany, Spain, Sweden, and Australia.

The business has grown quickly and the finance director has not been able to develop the cash management structures that she knows are beneficial for an international businesses.

Each office operates only within its own country. It receives incomes from corporate clients for whom it designs and manages advertising campaigns. Its expenditure largely consists of payments to media organisations that carry the advertisements. Both income and expenditure in each case is in domestic currencies.

Generally the offices have healthy case balances as they receive a large proportion of their fees in advance but pay mostly in arrears. Each office operates its own bank accounts. Some have overdraft facilities for contingencies. Since each office is responsible for its own banking the group has different banking partners in each country.

The Trident finance director would like advice on the most appropriate cash management approach. You can presume the finance director has very little treasury experience and she is not familiar with key cash management terms.
