Inventory Valuation Method Optimizer
PROCompare LIFO, FIFO, and Weighted Average Cost inventory methods to optimize tax liability, ensure GAAP/IFRS compliance, and make strategic accounting decisions.
Example Usage
“We’re a mid-size manufacturing company with $45M in annual revenue using FIFO for 15 years. With current inflation at 5-6%, we’re concerned about our tax bill. Our marginal tax rate is 21%, inventory is 12% of our balance sheet, and we turn inventory about 4x annually. Can you analyze whether switching to LIFO would be beneficial? Show me the tax impact, LIFO reserve requirements, and any compliance issues.”
