Cost Basis Inventory – TRES

Per-sub-transaction inventory view showing how each acquisition builds up the cost basis stack.

Why use this report?

Shows the cost basis inventory at the sub-transaction level: each inflow that added to your inventory, its quantity, and the cumulative inventory size. Use this to verify that all acquisitions are correctly tracked in the cost basis engine and to audit the inventory build-up over time.

Cost Basis Inventory

This report: sub-transaction level inventory build-up

Inventory verification, internal transfer audit

Cost Basis Stack Per Asset

Cost Basis Stack Per Wallet

Individual tax lots with purchase price and unrealized gains

Lot-level analysis, tax-loss harvesting

Cost Basis Roll Forward

Period summary: opening/closing cost basis with flows

Note: This report shows inventory at the sub-transaction level, not at the lot level. For individual tax lots with purchase prices and unrealized gains, use Cost Basis Stack per Asset or Cost Basis Stack per Wallet instead.

Tip: The inventory size column is cumulative: each row shows the total inventory after that sub-transaction. The last row for each wallet/asset combination is the current inventory.
