E-Commerce Accounting Challenges
E-commerce businesses face unique challenges that traditional bookkeepers cannot handle. Multi-channel sales, marketplace fees, inventory across warehouses, and sales tax in 40+ states require specialized expertise.
Sales Tax Nexus & Multi-State Filing
After the Wayfair decision, you likely have sales tax obligations in dozens of states. We determine where you have nexus, register your permits, and file returns so you never face surprise assessments or penalties.
Inventory & COGS Accounting
Whether you hold inventory in your garage, a 3PL warehouse, or Amazon FBA, tracking cost of goods sold correctly is critical for accurate profit margins and tax reporting. We reconcile inventory across every channel.
Marketplace Fees & Payment Reconciliation
Amazon referral fees, FBA storage charges, Shopify transaction costs, PayPal holds, Stripe chargebacks — the fee landscape is a maze. We track every fee by platform so you see true profitability per channel.
Multi-Channel Revenue Tracking
Selling on Amazon, Shopify, Walmart, Etsy, and wholesale simultaneously means revenue comes from everywhere. We consolidate all channels into one clean set of books with channel-level P&L reporting.
