The real problem
The inventory operations gaps that distort COGS, margins, and cash flow
These aren’t hypothetical. They’re the exact patterns we see when ecommerce brands outgrow their inventory systems, processes, or accounting workflows. The result is unreliable COGS, distorted margins, and inventory decisions made without clear financial visibility.
You count. The system disagrees. Huge adjustments and no clear cause. It’s untracked damages, samples, returns, and marketing pulls compounding.
Bundles, kits, multi-warehouse, FBA prep, refurbs, components. Generic IMS and QBO setups don’t capture them, so books never match operations.
Your IMS says one thing, your 3PL says another, FBA shows a third. Without a single source of truth, every reorder feels like a guess.
When freight, customs, 3PL fees, tariffs, and shrink aren’t included in COGS, your margins look better than they are. You’re making pricing decisions based on fiction.
Amazon, Shopify, Walmart, wholesale, TikTok Shop → every channel has its own quirks. Stock levels, allocations, and SKUs drift across platforms.
When your IMS and QBO aren’t reconciled, you have two versions of reality and no way to know which is right. Manual workarounds bleed time.

What we do
COGS accounting & inventory advisory matched to your operational reality
You might need a reliable monthly COGS process first. Or you might be ready for deeper advisory work around systems, workflows, landed cost, integrations, and SKU-level visibility. The two paths are deliberately separate so you know exactly what you’re buying.
The difference
Generalist accountant vs. COGS specialist
Inventory and COGS come with challenges that many traditional bookkeeping systems were never built to handle.
Swipe to compare →
| Capability | Generalist accountant | COGS specialist |
|---|---|---|
| Inventory count adjustments | Large adjustments with no clear cause |  Damages, samples, returns and pulls tracked |
| Bundles, kits & multi-warehouse | Generic IMS and QBO setups don’t capture them | Setup matched to how you actually sell |
| Landed costs | Freight, customs, 3PL fees and shrink left out | Landed cost workflow designed into COGS |
| Single source of truth for stock | IMS, 3PL and FBA numbers disagree | Inventory data reconciled across systems |
| IMS and QBO integration | Two versions of reality, manual workarounds | Integrations reviewed, reconciled and cleaned up |
| Monthly COGS method | Estimated or left until year end | Reasonable, decision ready monthly COGS |
| Multi-channel inventory | Stock levels and SKUs drift across platforms | Allocations tracked across every channel |
Working with a specialist makes the difference. Most generalist accountants aren’t built for inventory and COGS complexity — an ecommerce specialist ensures nothing falls through the cracks.
