The Forum of Private Business (FPB) is calling upon small to medium-sized enterprises (SME) to fully understand contracts before taking the decision to sign.

According to the FPB, fully comprehending the terms and conditions of a contract are vital to ensure that SMEs are not subjected to unexpected charges.

Indeed, the FPB maintains a helpline for members in need of guidance on a number of matters, including contract law.

"Stealth charges are an increasing worry for our members and we urge them to go through all documents with a fine-tooth comb before signing," said Nick Goulding, chief executive of the FPB.

"We realise this is a time-consuming process, but unfortunately it is the only way to be sure you will not fall victim," he added.

The issue has been raised by the FPB following the experiences of one of its members.

Established in 1977, the FPB represents around 25,000 member firms.
