When we notice a shortage, we have two options. Based on your decision, we can: A. Notify you and wait until you ship us the part to complete the order. B. Complete the order without that part and allow you to manually place it yourself when you receive the boards. To maintain the maximum flexibility and keep costs down as far as possible, we do not inventory your parts prior to processing the job. We’re an assembly house; we depend on you to supply the right quantity of the right parts. Please make sure you supply the correct parts. Even on a ten-day order, we may not notice a shortage until the day before the shipping date.
