First, your figure for increase in AP is wrong - it went from $1,673 million in Q2 to $2,301 million in Q3, which is an increase of $628 million. After adjusting for AR, the net effect is $480 million.This doesn't sound right to me. For example... if I order $25 million dollar of parts in Q1, and due to 45 day payment terms, I leave $15 million in accounts payable. The next quarter, since I'm increase production by 50%, I order $37.5 million dollars of parts in Q2, and due to 45 day payment terms, I leave $22.5 million in accounts payable. In Q3, I am building another 50% increase in production, so I order $56.25 million in parts, and again, due to 45 day payment terms, I leave $33.75 million in accounts payable.
Sure, I could pay before the 45 day payment terms say I need to pay. I'm not stiffing these suppliers nor am I delaying their payments beyond the standard payment terms. As a function of my increased production, the amount of parts I'm ordering increases, and therefore the amount in accounts payable also increases.
Now in Q4, I'm increase production by 10% over Q3. So now I'm ordering $61.9 million in parts, and I leave $37 million in AP. The suppliers again get paid exactly by schedule. AP goes up as a function of the amount of parts being ordered for production. It would be a neat trick if Tesla could increase production by that much and not have a corresponding increase in AP. You can go back and see Tesla's AP as a function of automotive cost of revenues and the percentage in Q3 2016 doesn't seem outsized at all.
Of course, there's the actual variability that we can't actually see since we have only quarterly snapshots.
To frame it better for Tesla specifically, accounts payable went up $491 million from Q2 to Q3. Receivables went up $148 million, so the net effect is $343 million. The total automotive cost of revenues went from $909 million to $1,517 million, or up $608 million. Overall inventory levels remained relatively flat, with a decrease in raw materials but an increase in work in progress and finished goods. Subtracting out service parts, the rest of the inventory decreased by $6 million. So the net effect of $343 million more in payables has to framed by the increase in the cost of revenues of $608 million. It doesn't look like to me that they are delaying payment any more than would be expected by increasing production by this much.
Second, I'm not saying anyone is getting stiffed. I'm just saying that scaling up production improves cash flow, as a one-time effect. And because the factory is shut down for 2-3 weeks in Q4, it's unlikely that Tesla will recieve these one-time improvements in cash flow in Q4. (And much smaller effects in Q1/Q2 than Q3, as further scaling of volume will be hard-fought.)
