****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** In NetSuite, you can handle the scenario of reducing the price of a unit when you get a rebate by creating a Discount item and using a negative amount with that Discount item on the Sales Order (SO). This will effectively deduct that amount from the line item above it. However, this approach does not impact the quantity and still calculates FIFO accounting. If you want to apply a discount to each line item based on quantity, you can use a non-inventory item with a negative quantity. This will allow you to apply a discount to each line item based on the quantity. As for the FIFO accounting, NetSuite can do FIFO on warehouse without using Lot Items for COGS. But if you want to make sure FIFO works for physical inventory as well, then you must use lot numberings. Please note that these solutions are based on the standard functionality of NetSuite and may require additional customization or configuration to fit your specific business processes.
