In short
What does an e-commerce accountant do?
An e-commerce accountant reconciles marketplace and payment payouts, Amazon, Shopify, PayPal and Stripe, against bank deposits, ties inventory and COGS to real sales, manages sales tax nexus across states and reports margin by SKU and channel. CPA Torrance runs all of it as one coordinated system, led by CPAs.

The core problem
Most e-commerce businesses don’t have a sales problem. They have a financial visibility problem.
Once you sell on more than one platform, ship from third-party warehouses and cross economic nexus thresholds in new states, the numbers in your bank account stop matching Seller Central. The bigger you grow, the less accurate your financial picture becomes.
Bookkeeping tracks transactions, not true profitability
Payouts arrive net of referral fees, FBA fees, ad spend, refunds and reserves, so gross sales and deposits rarely line up with true profit.
Sales tax exposure grows across multiple states
Inventory stored in fulfillment centers and rising sales volume can create nexus in states where you haven’t registered or filed.
Margins become unclear across channels
Without channel-level P&Ls, a best-selling SKU on Amazon can quietly lose money once fees, returns and storage are allocated.
Why the system breaks
The tools that run your store were never designed to work together. Without proper e-commerce CFO advisory, that creates hidden margin leakage and wrong scaling decisions.
- 01Bookkeeping records transactions, not profitability
- 02Tax planning reacts after decisions are made
- 03Inventory and COGS aren’t aligned with sales reality
- 04No CFO-level oversight connects the system
How CPA Torrance fixes it
One coordinated financial system for your store
We rebuild the financial layer underneath your store, with a strong focus on e-commerce tax compliance and long-term clarity.
Inventory and COGS tied to real sales data
Purchase cost, duties and inbound freight to fulfillment centers are built into unit cost, with FIFO or weighted-average methods applied consistently.
Product and channel-level margin visibility
Monthly contribution margin by SKU and by channel, after fees, returns, advertising and storage, not just top-line revenue.
CFO-level forecasting for scaling decisions
Cash flow and inventory purchasing forecasts that show how much stock you can fund before Q4 without straining working capital.
