Inventory → Import Whole Workbook (.xlsx) brings an entire Excel workbook in at once. Sheets link themselves: your inventory sheet creates the products, pricing fills in their tiers, purchase lots become batches with vendors and landed cost, reseller quantities become allocations, and sales and expenses come in as history.
You see exactly what each sheet will do before anything saves, and can change any of it. Duplicate rows are detected, so a tracker sheet repeating your ledger can't double-count.
