When the economy is slowing down, firms will accumulate unwanted inventories.   Those inventories still show up in GDP, but they are unsold.  Hence, GDP will be biased upwards.  Similarly, in good times businesses will reduce inventory levels to satisfy demand.  In this case, GDP growth will be understated.

To get a sense of the underlying pace of sales, economists will look at final sales which is GDP less the change  in business inventories. Final sales is GDP excluding the change in business inventories. Final sales climbed by 2,2% in the second quarter after gaining 1.9% in the fourth quarter.  Inventories fell $66.5 billion.  They may well be unchanged or even increase a bit in the third quarter and add 0.5% to growth in that quarter.
