E-commerce & Retail Taxation & Merchant Accounting
E-commerce operators handle thousands of high-frequency transactions across multiple channels (such as Shopify, Amazon, eBay, and WooCommerce). The major challenge is managing state sales tax economic nexus requirements established under the U.S. Supreme Court Wayfair ruling, while reconciling merchant gateway payouts against actual cash receipts. We assist e-commerce brands in auditing sales tax thresholds, valuing inventory assets, and automating bookkeeping.
Our e-commerce compliance solutions are designed to automate sales tax calculations, reconcile Stripe/PayPal balances, and track Cost of Goods Sold (COGS).

Frequently Asked Questions
What is economic nexus and how does it affect my online store?
Economic nexus means you are required to collect and pay sales tax in a state once your sales there exceed a certain limit, even if you don't have a physical store or employees there. The standard limit is $100,000 in sales or 200 transactions per year, though this varies by state. We track your sales volume to ensure you stay compliant in every jurisdiction.
How do you reconcile Stripe and PayPal transaction fees?
Payment gateways deposit payouts to your bank account net of their processing fees. Recording only the net deposit leads to underreporting both revenue and expenses. We set up automated tools to record gross sales and separate processing fee expenses, ensuring your tax reporting is accurate.
Should my e-commerce business use FIFO or LIFO inventory valuation?
FIFO (First-In, First-Out) assumes you sell your oldest inventory first, which matches physical product flow but can lead to higher reported profits (and taxes) during inflation. LIFO (Last-In, First-Out) assumes you sell your newest inventory first, which can lower taxable income when prices are rising. We analyze your product costs to help you select the most tax-efficient method.
What are the filing requirements for foreign-owned U.S. e-commerce LLCs?
Foreign citizens operating U.S. e-commerce businesses are subject to strict IRS reporting rules. Even if the LLC pays no federal income tax, it must file Form 5472 and Form 1120 annually to disclose transaction data. The penalty for failing to file starts at $25,000. We handle all compliance filings to protect your business.
How do we reconcile customer returns and chargebacks in our books?
We establish separate returns accounts to track refunds and inventory adjustments. This allows you to monitor return rates and ensure sales figures are accurate, while chargeback dispute fees are properly categorized as operating expenses.
