Force India conceded fourth place to Williams in the team standings despite Sergio Perez and Nico Hulkenberg securing a doubles points finish in the Formula 1 Italian Grand Prix in Monza on Sunday.
Perez held on to his grid spot to finish eighth while Hulkenberg crossed the chequered flag in 10th place after starting ninth on the grid, bringing home five points for the team.
Force India's closest rival Williams had a more productive outing with Valtteri Bottas and Felipe Massa finishing sixth and ninth for a total of 10 points.
It was only last week in Belgium that Force India had surpassed Williams after amassing 22 points through Hulkenberg and Perez, who came fourth and fifth respectively.
Williams are back in fourth with 111 points, three more than Force India.
