Advanced inventory controls

Built for operators who have outgrown basic Shopify inventory apps.

SwapTrak goes beyond quantity-on-hand. It connects stock, cost, source, warehouse, order, and correction history so your inventory can withstand real operational and accounting scrutiny.

Live now

Exact inventory source traceability

Connect a sales line to the purchase receipt, transfer, opening balance, adjustment, or reviewed fallback that supplied its COGS.

  • Purchase-order source references
  • Quantity and landed cost used
  • Warehouse and movement context
Live now

Independent warehouse ledgers

Maintain inventory quantity, rolling cost, FIFO eligibility, reorder controls, and movement history at each location.

  • Warehouse-specific stock and costs
  • Location-aware sales and purchase orders
  • All-warehouse and single-location reporting
Live now

Cost-preserving stock transfers

Move stock between warehouses while creating destination cost layers based on the source allocations.

  • Preserve original receipt provenance
  • Protect transfers already consumed
Live now

True landed-cost allocation

Capitalize the charges that make inventory more expensive than the supplier's unit price.

  • Freight, tax, surcharges, and fees
  • Line and order discounts
  • Persisted landed cost per receipt line
Live now

Barcode and SKU catalog integrity

Carry Shopify barcode data and use exact SKU, alternate SKU, variant, and normalized-name matching during catalog migration.

  • Barcode-aware product records
  • Variant and inventory-item linkage
  • Duplicate and archived-SKU detection
Live now

Warehouse inventory counts

Compare expected stock with physical counts, then record discrepancies, notes, adjustments, and count-session history.

  • Bulk counts by selected warehouse
  • Expected-versus-counted variance
  • Review and conflict handling
Live now

Component-level bundle COGS

Cost kits and assemblies from the FIFO layers consumed by their underlying inventory components.

  • Virtual availability from component stock
  • Warehouse-specific bundle capacity
  • Component source allocation trail
Live now

Historical inventory reconstruction

Replay receipts, sales, transfers, and opening balances by effective date instead of trusting spreadsheet upload order.

  • Deterministic chronological replay
  • Negative-inventory and fallback diagnostics
  • Safe preview before cutover
Advanced roadmap

Serial, lot, batch & expiration tracking

Extend source-level inventory provenance into individual identifiers and controlled groups for warranty, recall, and expiration workflows.

  • Unit-level serial assignment
  • Lot and batch receiving
  • Expiration and recall visibility

Advanced without the flagship bloat

The controls of a serious inventory system—without rebuilding your business around an ERP.

SwapTrak is designed for merchants who need more than a Shopify stock counter, but do not want the cost, implementation project, or operational rigidity of a traditional ERP.

  • Start with Shopify and CSV data instead of a year-long deployment
  • Keep every cost calculation connected to real inventory movements
  • Use advanced controls only where your operation needs them
  • Preserve an audit trail without sacrificing operator speed
Independent warehouse costing

Inventory, average cost, FIFO layers, and history by location.

3 locations
Transfer-layer provenance

Destination layers remain connected to the source warehouse costs.

24 units
Physical count discrepancy control

Expected, counted, variance, note, and adjustment session preserved.

+1 variance
Barcode and alternate SKU matching

Link catalog variants without creating hidden duplicates.

High confidence

One connected inventory ledger

From supplier receipt to defensible order margin.

Every inventory event carries the cost, location, source, and audit context needed by the next step.

01 · Receive

Capitalize true landed cost

Allocate freight, tax, surcharges, discounts, and other charges to the received units.

02 · Store

Create warehouse cost layers

Update stock, rolling average cost, and dated receipt layers in the destination warehouse.

03 · Move

Preserve transfer provenance

Carry allocated source costs into destination layers when inventory changes locations.

04 · Sell

Assign FIFO COGS

Consume the oldest eligible warehouse layers and persist the order's source allocations.

05 · Defend

Reconcile and report

Review COGS, margin, warehouse history, fallback status, and the exact source of every cost.

Competitive capability matrix

More control than a basic Shopify app. Less friction than a legacy ERP.

Comparison reflects general product-category positioning, not a claim about every individual competing product.

Source-level accountability

A serious inventory system should explain a number—not merely display it.

SwapTrak keeps the receipt layers, warehouse, movement, landed cost, transfer history, quantity, and fallback status behind order COGS.
