GDP with Intermediate Production
You’re looking for gross output; GDP is final output. 

Per the BEA:


  Economy-wide, real gross output—principally a measure of an industry's sales or receipts, which includes sales to final users in the economy (GDP) and sales to other industries (intermediate inputs)


For calculation purposes, it’s generally assumed that a firm purchasing a good (for example, a computer) is using it as an intermediate input, while a household purchasing the same good is using it as consumption (so it’s a “final sale” counted in GDP), though corrections are applied in particular cases where this assumption doesn’t hold well. Cases where households act as producers, like farms and real estate, are prime areas for these corrections.
