Investing surplus cash in a term deposit

Last updated more than 5 years ago

A term deposit, also called a deposit account, is used to invest a sum of money for a predefined term and at a predefined interest rate.

The purpose of a term deposit is to invest surplus cash in such a way as to:

  • ensure sufficient liquidity and returns;
  • reduce financial charges;
  • know the maturity date and final amount;
  • invest capital without incurring any risk.

Objective: a term deposit enables the investment and productive management of a business' cash.

Who is concerned

Term deposits are available to the self-employed and any type of business with surplus cash that is not immediately required. This surplus may be the result of:

  • the collection of large payments;
  • the settlement of large invoices for works and services provided;
  • long terms of payment granted by suppliers;
  • efficient cash management.

As businesses generally seek the simplest solutions that offer the best return without the risk of losing capital, they often opt for a term deposit.


Since a term deposit is simply a secondary account linked to a main account, the only prerequisite is the existence of a current account.
