Inventory Module

Documentation for stock quantities, adjustments, transfers, variants, availability, and inventory movement.

Exact functionalities

Stock balance tracking by item and variant, movement ledger, reservations, cycle counts, adjustments, and availability status. Supports transaction-safe quantity updates and movement reason capture.

  • Real-time stock quantities
  • Inventory adjustments and movement tracking
  • Variant-aware product stock
  • Availability monitoring
  • Operational inventory visibility

Workflow blueprint

Inbound receipt posts positive movement, outbound fulfillment posts issue movement, cycle count posts variance adjustments, and reservation lifecycle moves quantities between available and reserved states.

  1. Capture Inventory transaction input and context
  2. Validate permissions and business policy
  3. Commit lifecycle transition with audit metadata
  4. Propagate updates to dependent modules
  5. Review exceptions and close operational cycle

Data model and records

Item, Variant, StockBalance, StockMovement, StockReservation, and StockAdjustment with timestamps, source references, and reason codes to preserve operational traceability.

  • Item
  • Variant
  • StockBalance
  • StockMovement
  • StockReservation
  • and StockAdjustment with timestamps
  • source references
  • and reason codes to preserve operational traceability

Controls and business rules

No negative stock balance unless explicitly allowed by policy, adjustment must include reason code, and reservation release must restore available quantity. Counts and adjustments should remain auditable.

Define explicit and valid status transitions for Inventory

Require mandatory fields before high-impact actions

Block unauthorized overrides without approval evidence

Preserve immutable audit history on critical events

Apply idempotency and duplicate protection on write paths

Integrations

Connected to Sales and Ecommerce for promise-to-ship, Warehouse for physical execution, and MRP or Manufacturing for planned and consumed material.

Failure modes and safeguards

  • Missing required data at transaction entry
  • Unauthorized status transition attempts
  • Cross-module reference mismatch after updates
  • Duplicate mutation attempts from retries
  • Delayed downstream synchronization and stale dashboards

Implementation and rollout plan

  1. Define owner, scope, and process objective
  2. Configure lifecycle, permissions, and defaults
  3. Run pilot workflows including edge cases
  4. Validate KPI outputs and integration behavior
  5. Train users and publish SOP guidance
  6. Execute staged go-live with checkpoint review
