Inventory Accounting & Operations

Inventory is one of the most complex — and expensive — components of any product-based business. Small errors compound quickly, impacting margins, cash flow, fulfillment efficiency, and financial accuracy. Insight Growth Consulting helps brands build inventory systems that are accurate, audit-ready, and engineered for scalable growth.

Costing Models (Standard, Landed, Actual)

Accurate costing is the foundation of reliable margins.
We assess your current costing method, identify gaps, and implement a costing structure tailored to your supply chain and product model, including:

  • Standard cost development

  • Landed cost calculations (duties, freight, surcharges)

  • Automated costing inside your ERP

  • Variance tracking and reporting

  • COGS alignment with operational reality

→ Outcome: predictable margins and cleaner month-end closes.

Perpetual Inventory System Setup

Transitioning from periodic to perpetual inventory unlocks real-time visibility and better decision-making. I help teams implement:

  • Real-time quantity tracking

  • Standardized warehouse processes

  • Proper accounting mappings (receipts, picks, returns, adjustments)

  • 3PL alignment

  • Monthly variance reporting

→ Outcome: accurate on-hand inventory and faster close cycles.

Warehouse-to-GL Reconciliation Processes

Most brands struggle to keep warehouse numbers aligned with accounting.
We create a reconciliation framework that:

  • Matches WMS/3PL data to ERP inventory

  • Identifies discrepancies in real time

  • Defines a monthly or weekly reconciliation cadence

  • Provides shrink and adjustment visibility

  • Supports audit readiness

→ Outcome: fewer surprises and stronger financial controls.

SKU-Level Margin Analysis

We build SKU-level margin models that reveal which products drive profit — and which erode it.
This includes:

  • True SKU profitability

  • Pricing analysis

  • Product mix optimization

  • Lifecycle margin modeling

→ Outcome: better pricing, forecasting, and purchasing decisions.
