But doesn't Tesla have financial advisors, engineers that calculate this kind of thing? Sure they're in growth mode but to repeatedly manufacture large quantities of a product more than what's being asked for especially only when payment is at the sale seems like it should raise some eyebrows in the finace department. Lamborghini has already sold out of 2023 and 2024 Hurrican allotments. Many were pre-paid in full or a significant chunk of the price was deposited. Example The Gallardo was the best selling Lamborghini of all time 15,000 plus units sold. Lamborghini is in growth mode but has no new vehicles sitting on the lot. A few months ago I wandered around Lamborghini of Scottsdale. Every single new Hurrican had "Sold" on the window none were awaiting a buyer.I have touched in this before. Tesla reports vehicles manufactured and deliveries. Remember, Tesla is in rapid growth mode both at existing factories and building new factories. As production grows, there is a natural tendency for the gap to increase; all the numbers grow. Additionally, the Model 3 is only made in Fremont for the US market. Tesla builds in batches for regional delivery. How long does it take to deliver truckloads of cars from Northern CA to the Mid West and further East? Basically all over America. The term inventory is misleading; in business the term is Days of Sales Outstanding. DSO is an important component of cash flow because Tesla does not get paid until actual customer delivery.
In manufacturing, in general the only time production = sales or production < sales is during a slowdown or factory production issues.
Your "5 straight quarters" is a perfect example of a company in rapid growth mode. All numbers grow, for numerous reasons.
This is all from my career in statistical forecasting. You report actuals for closed fiscal periods and forecast for future periods. Again, DSO is a factor in cash flow analysis. Companies obviously work to minimize this number.
