Operations Accounting Controller Jobs in Colorado

About the Role

We are a fast-growing multi-channel e-commerce company seeking a hands-on Accounting Controller to own our financial operations end to end. This is not a traditional controller role: you'll live in the day-to-day mechanics of marketplace settlements, high-SKU inventory accounting, and the integration between SellerCloud and QuickBooks that keeps our books accurate. The ideal candidate understands the unique accounting challenges of selling across Amazon, Walmart, eBay, Shopify, and other channels, and can translate that operational complexity into clean financials.

You'll be the person leadership trusts to answer "what's our real margin on this SKU?" and "did that Amazon settlement actually reconcile?"

Key Responsibilities

Core Accounting & Close

• Own the full month-end and year-end close process, delivering accurate financials within 10 business days
• Maintain the general ledger and chart of accounts in QuickBooks, structured to support multi-channel and multi-entity reporting

• Produce monthly financial statements (P&L, balance sheet, cash flow) with variance analysis against budget and prior periods
• Ensure compliance with US GAAP and maintain documentation for audit readiness

E-Commerce & Marketplace Accounting

• Reconcile marketplace settlements and payouts (Amazon, Walmart, eBay, Shopify, etc.) against gross sales, fees, refunds, chargebacks, and reserves
• Account for and reconcile payment processors (Stripe, PayPal, Amazon Pay, Affirm, etc.)

• Own inventory accounting in a high-SKU environment, ensuring SellerCloud inventory data ties to the GL
• Calculate and maintain landed cost (product cost, freight, duties, tariffs, 3PL/warehousing) for accurate COGS
• Oversee cycle counts and physical inventory reconciliation; investigate and resolve shrinkage and variances
• Manage purchase order accounting, vendor bills, and inventory-in-transit
• Monitor inventory valuation, obsolescence, and write-down reserves

Systems & Integration

• Own and optimize the SellerCloud-to-QuickBooks data flow, ensuring orders, inventory, COGS, and fees sync accurately

• Identify and implement process automation to reduce manual reconciliation and close time
• Partner with operations and IT on system improvements, mappings, and data integrity

• Coordinate with external tax preparers and auditors
