Bookkeeping for Amazon Sellers

Selling on Amazon can be incredibly profitable—but behind every successful seller is a strong financial system. From rapidly shifting inventory costs to sales tax obligations and Amazon’s constantly evolving fee structure, your business needs more than generic bookkeeping. You need a solution built specifically for eCommerce.

​

At Next Edge CPA, we specialize in bookkeeping for Amazon sellers. Whether you're an FBA merchant, private label brand, or multi-channel seller, our team understands the unique accounting challenges of eCommerce and provides reliable, tax-ready financials that drive smarter decisions and sustained growth.

​

 

Why Amazon Sellers Need Specialized Bookkeeping

Amazon sellers often operate at high volume with thin margins, complex cost structures, and limited financial visibility unless the books are organized properly. Unfortunately, most traditional bookkeepers don’t understand Amazon’s reporting systems or the nuances of eCommerce.

​

Here’s why bookkeeping for Amazon businesses is unique—and why it matters:

​

1. High Volume, Low-Margin Sales

Amazon businesses often involve thousands of small transactions per month. Without automation, it’s easy for inaccuracies to add up and distort your profitability.

​

2. Complicated Payouts and Fee Structures

Amazon deposits funds every two weeks—after deducting fulfillment fees, referral fees, advertising, returns, and adjustments. Decoding these settlements and translating them into clean accounting entries requires specialized knowledge.

​

3. Inventory Management

Tracking cost of goods sold (COGS) across shipments, returns, and multiple warehouses is essential for accurate financials. Without a system in place, inventory inaccuracies can lead to misstated profits and IRS trouble.

​

4. Sales Tax Nexus and Compliance

Amazon’s nationwide footprint means many sellers have sales tax obligations in multiple states. Proper bookkeeping is necessary to track where tax has been collected (and where it hasn’t).

​

5. Multi-Channel Complexity

Many Amazon sellers expand into Shopify, Walmart, or international marketplaces. Consolidating financials from multiple platforms can be time-consuming without expert help.

Our Bookkeeping Services for Amazon Sellers

At Next Edge CPA, we offer a comprehensive bookkeeping system tailored to the Amazon ecosystem. Whether you’re just launching your store or scaling into a 7-figure business, we provide clarity, control, and compliance at every stage.

​

1. Transaction-Level Accounting

We sync directly with your Amazon Seller Central account and use eCommerce-focused software to:

• Break down biweekly Amazon settlements
   

• Track revenue, fees, returns, and reimbursements
   

• Allocate costs correctly between COGS, marketing, and operations
   

This ensures you always know your real income, not just what’s hitting your bank account.

​

2. Inventory and COGS Tracking

​

We help you:

• Track product costs across multiple suppliers or SKUs
   

• Allocate freight, shipping, customs, and prep center costs
   

• Reconcile beginning and ending inventory each month
   

• Use accrual-based accounting for accurate profit visibility
   

This provides a true picture of your margins and helps you avoid costly inventory mistakes.

​

3. Monthly Financial Statements

Each month, we deliver clear, concise reports designed specifically for Amazon sellers, including:

​

• Profit & Loss by product line or marketplace
   

• Balance Sheet with inventory and liability tracking
   

• Cash Flow Report
   

• Ad spend and ROI metrics
   

• Trend analysis for key KPIs (ACoS, TACoS, ROAS, and net margin)
   

These reports empower you to scale confidently and avoid surprises.

​

4. Sales Tax Tracking

We help monitor your sales tax obligations by state, integrating with sales tax automation tools like:

• Avalara
   

• TaxJar
   

• Sellerboard
   

We ensure you know which states you're collecting in, and what your potential exposure may be.

​

We connect your accounting system with platforms like:

​

• Amazon Seller Central
