Commercial Finance Manager

Overview

This role owns the financial performance of an e-commerce and marketplace business, with a primary focus on Amazon, TikTok Shop, and other direct-to-consumer e-commerce channels. The position provides end-to-end accountability for channel profitability—owning the full P&L from net revenue down to gross margin—and serves as the financial gatekeeper for promotions, discounts, and marketplace fees that impact those results.

Responsibilities

Net Revenue to Gross Margin Ownership

• Own the complete P&L waterfall—from gross sales through net revenue to gross margin—for Amazon, TikTok Shop, and all other e-commerce/marketplace channels.
• Build and maintain SKU- and channel-level COGS models, including landed cost, freight/duties, co-packing, fulfillment, and pick/pack/ship, to estimate gross margin percentage (GM%) by channel, SKU, and bundle/offer.
• Partner with supply chain and procurement to keep COGS assumptions current as vendor costs, freight rates, and tariffs change, and quantify margin impact before changes flow through to the P&L.
• Maintain a standard bridge from gross sales to net revenue to gross margin so each channel and offer is measured consistently.

Promotional Calendar, Discounts & Pricing Governance

• Own the financial modeling of the promotional calendar across Amazon (Lightning Deals, Coupons, Prime Day/Big Deal Days, Subscribe & Save) and TikTok Shop (flash sales, campaign vouchers, creator/affiliate-driven promotions, GMV Max spend).
• Quantify net revenue and margin impact of every discount, coupon, deal-funding request, and bundle offer before launch, and provide clear go/no-go recommendations.
• Track promotional spend and discount depth against plan, and analyze post-promo performance including incrementality, margin dilution vs. unit lift, and halo effects.
• Partner with brand and growth marketing teams to maintain a shared promotional calendar view tied to expected P&L impact.

Retailer & Marketplace Fee Management

• Build and maintain a fee assumption library covering Amazon referral fees; FBA fulfillment and storage fees; returns/refund processing; and TikTok Shop commission, ad spend, and affiliate/creator commission structures.
• Reconcile marketplace settlement/payout reports against modeled expectations, flagging fee-schedule changes, overcharges, or anomalies for follow-up.
• Monitor and forecast the impact of new or changing retailer fees (fee schedule updates, new program fees, chargebacks, storage limits) on channel profitability.

Forecasting, Reporting & Analysis

• Build and maintain rolling revenue, COGS, and gross margin forecasts by channel and SKU; report variance to plan/forecast weekly and monthly.
• Develop and maintain dashboards (Excel and/or BI tooling) providing visibility into net revenue, GM%, promotional spend, and fee trends by channel.
• Support month-end close for e-commerce channels, including accruals for promotions, discounts, returns reserves, and marketplace fees.

Cross-Functional Business Partnership

• Serve as an embedded finance partner to e-commerce, Amazon/marketplace, and DTC teams, providing scenario and “what-if” modeling for pricing changes, promotions, and new SKU or bundle launches.
• Present channel performance, margin bridges, and recommendations to Finance and Commercial leadership.
• Identify and drive margin improvement opportunities across pricing, promotional strategy, fulfillment method, and fee optimization.

Requirements

• Bachelor’s degree in Finance, Accounting, Economics, or a related field; MBA or CPA a plus.
• 4–7+ years of experience in FP&A, commercial finance, or financial analysis, ideally within CPG, DTC, or e-commerce, with direct exposure to Amazon and/or TikTok Shop economics.
• Strong working knowledge of marketplace mechanics, including Amazon Seller/Vendor Central fee structures and FBA, plus TikTok Shop commission, ads, and affiliate/creator commerce models.
• Demonstrated ability to build detailed SKU-level financial models from scratch (COGS, margin bridges, promo P&Ls) in advanced Excel/Google Sheets.
• Experience with BI/reporting tools (e.g., Looker, Tableau, Power BI) and ERP systems (e.g., NetSuite) preferred.
• Strong analytical and problem-solving skills with high attention to detail and data accuracy.
• Excellent communication skills and comfort operating cross-functionally with e-commerce, brand marketing, supply chain, and accounting teams.
• Self-starter able to manage competing priorities across multiple fast-moving channels.

Preferred Qualifications

• Experience in the supplement, beverage, or broader CPG/consumer products industry.
• Hands-on familiarity with Amazon Seller Central, TikTok Shop Seller Center, and analytics tools such as Helium 10, Jungle Scout, or similar.
• Prior experience managing or supporting a promotional calendar process in a marketplace environment.

Compensation & Benefits

• Base salary: $90,000 per year (starting range); final offer based on experience and skillset.
• Comprehensive medical, dental, and vision benefits, plus savings plans.
• 401(k) savings plan with a company match.
• Flex PTO plan, sick time, and paid holidays.
• Monthly stipend to spend on products and gear.
