Inventory Tracker

Inventory valuation you can actually trust.

Track every inflow and outflow with weighted-average costing, build assemblies with real bill-of-materials and labor roll-ups, and post the journal entries automatically.

Weighted-average cost is too important to guess.

When unit cost is an estimate, so are your margins, your COGS, and your balance sheet. SideLedger recalculates weighted-average cost on every receipt and rolls assembly costs up from their parts — so valuation is a fact, not folklore.

Every movement, costed correctly

Purchases, sales, adjustments, and returns each flow through the right costing logic, with weighted-average cost recalculated as stock arrives.

  • Purchase, sale, adjustment & return transactions
  • Weighted-average cost recomputed on every inflow
  • Bulk entry via form, CSV/Excel, or pasted text

Assemblies with real cost roll-ups

Build a bill of materials — including sub-assemblies — and SideLedger rolls component costs up and adds per-unit labor, with circular references prevented.

  • Multi-level BOM (assemblies inside assemblies)
  • Material roll-up + adjustable labor per build
  • Stock validation and component consumption on build

Steel bracket × 2$6.36
Hinge × 1$14.40
Fasteners × 8$1.04
Labor (0.4 hr)$18.00
Total unit cost$39.80

Adjust, dispose, and revalue cleanly

Record market adjustments, damage, or obsolescence, and dispose of stock with gain or loss computed against adjusted cost.

  • Basis adjustments: market, damage, obsolescence, revaluation
  • Disposals: sold, written off, donated, scrapped, returned
  • Gain/loss against adjusted unit cost

Sale — cost of goods sold

Methods & standards

Costing that holds up to scrutiny.

Valuation and assembly costs are computed with the standard formulas, recursively for nested assemblies.

GAAPWeighted-Average CostMulti-level BOM

Weighted-average cost

(Existing Value + New Value) ÷ (Existing Qty + New Qty)

Recalculated automatically every time inventory is received.

Inventory value

Quantity on Hand × Unit Cost

Current carrying value of each item, in total across the register.

Assembly material cost

Σ (Component Unit Cost × Qty Required)

Rolled up recursively, so sub-assembly costs flow into the parent.

Assembly total cost

Material Cost + Labor Cost per Unit

Per-unit cost including the labor you set for each build run.

Adjusted unit cost

Adjusted Value ÷ Quantity on Hand

Unit cost after basis adjustments like damage or revaluation.

Disposal gain / loss

Proceeds − (Adjusted Unit Cost × Qty Disposed)

Computed automatically and posted with the disposal entry.

Auto-generated journal entries

Journal entries for every transaction type.

Purchases, sales, assembly builds, and disposals each generate a balanced, ready-to-post journal entry — so your inventory ledger always matches the books.
