CPA & Accounting Services for Amazon Sellers
Accounting that goes beyond your Amazon payout
Amazon selling involves more than recording deposits into a business bank account. FBA fulfilment charges, referral fees, advertising, refunds, inventory costs and marketplace tax adjustments can make it difficult to determine your actual profit. Shami CPA provides accounting and tax support for business owners who need organized financial records and clearer insight into their e-commerce operations.
An Amazon seller’s revenue, expenses and cash receipts do not always appear in the same place or at the same time. Customer orders generate sales activity, but Amazon settlements may combine multiple transactions, deduct fees, reflect refunds and include adjustments before funds reach the seller’s bank account.
This makes settlement reconciliation essential. Recording only the net bank deposit can obscure gross sales, selling expenses, refund activity and other amounts that should be accounted for separately.
Inventory introduces another layer of complexity. Sellers may pay suppliers well before products sell, incur freight and import-related costs, store inventory in fulfilment centres, and replenish products based on sales forecasts. A business can report positive sales while tying up substantial cash in unsold stock.
Accounting must therefore connect three views of the business:
-
Marketplace activity: orders, returns, refunds, fees, advertising charges, reimbursements and settlements.
-
Inventory and operating costs: supplier invoices, freight, landed costs where applicable, storage, fulfilment and other business expenses.
-
Business performance: revenue, cost of goods sold, gross profit, operating expenses, cash flow and taxable income.
The accounting process should also reflect how the seller operates. An individual running a small reselling business may have different reporting needs from an incorporated private-label brand selling in Canada and the United States.
Shami CPA’s bookkeeping, accounting and business-tax services can provide a foundation for organizing these records and preparing the financial information needed for business decisions and tax compliance, subject to confirmation of the specific engagement requirements.

Amazon Sellers: Key Tax and Financial Issues That Can Affect Your Profit
Interpreting Amazon Transaction Reports
Amazon order, settlement, fee and tax reports capture different aspects of marketplace activity. These records must be interpreted together to establish accurate revenue, expenses and outstanding balances. Treating every report total as separate income can distort financial results.
What sellers should monitor:
- Gross sales, refunds and settlement adjustments.
- Marketplace fees and advertising charges.
- Bank deposits and outstanding settlement balances.
Inventory Costs and Year-End Valuation
Amazon sellers may hold stock across multiple fulfilment centres or third-party warehouses. Supplier purchases, freight, returns and unsold goods affect inventory valuation and cost of goods sold. Appropriate accounting methods help ensure that reported expenses reflect the inventory actually sold during the relevant period.
What sellers should monitor:
- Opening and closing stock values.
- Supplier invoices and freight costs.
- Damaged, returned and unsellable inventory.
Marketplace Charges and Business Expenses
Referral commissions, fulfilment fees, storage charges, subscriptions and advertising costs influence an Amazon seller’s operating margins. Consistent expense classification supports meaningful financial comparisons. Taxes charged on Amazon’s own services should also be distinguished from transaction taxes collected on customer purchases.
What sellers should monitor:
- Platform invoices and fee adjustments.
- Advertising expenditure and storage charges.
- Taxes applied to marketplace services.
Canadian GST/HST Responsibilities
Canadian sellers should assess their GST/HST registration, collection and reporting obligations based on their circumstances. Marketplace collection arrangements may affect responsibility for particular transactions, but they do not automatically eliminate every seller obligation. Applicable provincial sales-tax requirements may also require separate consideration.
What sellers should monitor:
- Registration status and applicable tax obligations.
- Marketplace-collected amounts and direct sales.
- Purchase documentation supporting eligible input tax credits.
U.S. State Sales-Tax Exposure
U.S. sales-tax obligations vary by state and, where applicable, local jurisdiction. Marketplace-facilitator laws may assign collection responsibilities to Amazon for covered transactions, but sellers can have additional obligations arising from direct sales, inventory locations or other business activities.
What sellers should monitor:
- States where inventory is stored or business occurs.
- Sales made outside Amazon.
- Applicable registration and filing requirements.
Cross-Border Income-Tax Obligations
Selling into another country can introduce income-tax considerations beyond those associated with the seller’s home jurisdiction. Entity structure, tax residence, ownership and business activities may influence filing responsibilities. Selling through Amazon.com or storing inventory in the United States does not, by itself, determine the complete tax outcome.
What sellers should monitor:
- Business structure and tax residence.
- Activities and inventory locations across borders.
- Potential foreign filing and treaty considerations.
