The term "not sufficient funds'' refers to a situation where an individual or company does not have enough money in their account to cover a particular transaction - this could be a bill, a check, or a paycheck. Therefore, "not sufficient funds meaning" in the context of payroll and paystubs refers to when an employer does not have enough money in their account to pay their employees the wages they are owed. Consequently, the employers' bank refuses to complete the transaction or transfer. Paying employees regularly and on time is crucial for maintaining trust and a solid working relationship.
