    The Financial Complexity of Multi-Channel Commerce

    Selling across Shopify, Amazon, Walmart, and TikTok Shop creates revenue, fee, and tax tangles that defeat generic bookkeepers.

    Sales Tax

    Marketplace Facilitator Tax

    Amazon and others remit sales tax, but you still need to reconcile and file zero-balance returns in many states.

    Settlements

    Channel Settlement Reconciliation

    Each marketplace pays net of fees, refunds, and adjustments. Gross revenue must be reconstructed for GAAP.

    Inventory

    Multi-Warehouse Inventory

    FBA, 3PL, and brand-owned stock across locations must reconcile to the GL, not just to spreadsheets.

    Reserves

    Returns & Refund Accruals

    High return rates demand defensible reserve methodologies, especially around year-end.

    Margins

    COGS by SKU & Channel

    Channel-level contribution margin requires landed cost discipline and per-SKU profitability tracking.

    Funding

    Investor & Lender Scrutiny

    DTC funding rounds and inventory loans both demand clean GAAP financials.
