The free toolset grew to 25 calculators built for real wholesale math — margins, commissions, landed cost, case packs, break-even, reorder points, and the new GMROI, freight-per-unit, inventory turns, cash-discount (2/10 net 30), and container-fill tools. Every tool page now carries a clear, consistent "How it works" section explaining the inputs, the formula, and how to use the result.
