In an inertia frame of reference, as long as the object is not accelerating, the net force acting on it is zero, according to Newton's second law. An object that is not accelerating does not require it to be not moving at all, it just means that the object is traveling at constant velocity. An example would be a block of ice sliding across a smooth, horizontal surface, where the only 2 forces acting on it (gravity and normal) are equal in magnitude and opposite in direction. Therefore, the block of ice does not experience a net force and is said to be in equilibrium.
