Fractional CFO for E-commerce Companies

CPA-led financial advisory for DTC brands and growth-stage retail across channels and borders.

Your Shopify dashboard shows 30% month-over-month growth. Your bank balance is declining. Inventory is eating cash faster than revenue replaces it. Amazon settles in 14 days. Wholesale pays in 45. Returns are eroding the margin you never measured. That disconnect between top-line growth and actual cash position gets worse at every stage. COGS doesn't reconcile to inventory. Channel profitability is invisible. Working capital swings $500K+ per quarter. By the time the problem is obvious, the fundraiser is already at risk.

When You Need This

The need for fractional CFO support is almost always tied to a specific moment — a decision that exposes the limits of the current financial infrastructure.

1

Scaling from $500K to $5M in Annual Revenue

Operations that worked at launch collapse under growth. Inventory accounting breaks. Monthly close takes three weeks. Margins are invisible. Decisions rely on gut feeling, not data.

2

Managing Inventory Across Multiple Channels

Shopify, Amazon, wholesale, B2B. Each channel has different margins, payment terms, and tax treatment. The trial balance doesn't reconcile to what's actually in the warehouse.

3

Preparing for Series A, Debt Financing, or Acquisition

Investors and lenders want clean financials, auditable inventory, and a clear cash position. The current accounting is DIY. There are 10–12 weeks to get investor-ready.

4

Expanding Across U.S. and Canadian Markets

Cross-border shipping triggers tariffs, duties, currency exposure, withholding, and dual tax filing. A single-country accountant doesn't coordinate both sides.

5

Managing Seasonal Cash Swings

Q4 peaks, Q1 crashes. Working capital swings $500K+ each quarter. Without a forecast that shows when bridge financing is needed, cash runs out before the next peak.

Client Profile

Who This Service Is For

E-commerce Founders Scaling Without a CFO

Launched on Shopify, hit $1M in year one, now at $3M and drowning in complexity. Accounting is manual. Forecasts are nonexistent. Financial decisions are reactive.

DTC Brands Managing Multiple Revenue Streams

Direct to consumer, wholesale, and marketplace channels — each with different margins, payment timing, and tax treatment. The general ledger doesn't reflect reality.

Early-Stage Finance Leaders Lacking Strategic Depth

A Controller or part-time finance manager handles monthly close and reconciliations. But cash runway, inventory optimization, and multi-jurisdictional tax strategy require a different level of financial thinking.

Founders With Inventory Health and Working Capital Concerns

Inventory has scaled to $500K+. Whether it's aged, slow-moving, or obsolete is unclear. Cash is trapped. Physical count reconciliation and aging analysis are overdue.

U.S.–Canada E-commerce Operators

Shipping across the border. Currency, tariffs, duties, and dual tax compliance create ongoing headaches. Separate accountants per country don't coordinate, and gaps compound.

Companies Preparing for Institutional Investment or Debt Financing

Lenders want auditable inventory, clean revenue accounting, and a clear cash position. The current setup will not pass audit scrutiny. There are 10–12 weeks to get there.

Scope of Work

What This Service Addresses

The fractional CFO function for ecommerce addresses the gap between top-line growth and actual cash position — connecting inventory, multi-channel revenue, and working capital into one coherent financial picture.

Build Inventory Accounting That Reconciles to Reality

TYM establishes a FIFO or weighted-average COGS method, integrates the ecommerce platform (Shopify, WooCommerce) and warehouse system with accounting records, and creates a monthly inventory reconciliation. The balance sheet reflects the actual stock at the accurate landed cost. The P&L shows true margin by product and channel.

Integrate Multi-Channel Revenue and Payment Settlement

Revenue streams are split across platforms. TYM creates a daily or weekly revenue-by-channel breakdown, tracks payment settlement timing (Shopify net-2, Amazon net-14, Stripe net-1), and reconciles P&L to actual cash received. Profitable channels are separated from cash sinks. Settlement timing becomes predictable.

Design Cash Flow Forecasts for Working Capital

E-commerce cash flow is driven by inventory timing, payment terms, and seasonal demand. TYM builds a rolling 12-month forecast that models inventory buildup, supplier payment dates, customer settlement delays, and seasonal peaks. Scenarios include base case, upside (growth accelerates), and downside (ad spend rises, conversion dips). Working capital needs for raises or financing are modeled.

Coordinate Tax Compliance Across Channels and Jurisdictions

Sales tax nexus is complex across U.S. states. Marketplace facilitator rules affect obligations. Cross-border shipments trigger tariffs and duties. TYM maps obligations by channel and state/province, coordinates with your CPA on compliance, and captures ecommerce-specific deductions (fulfillment labor, returns handling, advertising spend). For cross-border operations, both U.S. and Canadian positions are managed.

Analyze Margin and Unit Economics by Product and Channel

Product-level and channel-level profitability are invisible without proper accounting. TYM creates monthly margin reporting: contribution margin per SKU, blended margin by channel, and CAC payback by cohort. The data shows what to sell more of, what to discontinue, and where to invest marketing spend.

Cross-Border

Treaty & Coordination Considerations

E-commerce companies operating across the U.S. and Canada are subject to the U.S.–Canada Tax Treaty. Treaty provisions affect withholding rates on intercompany payments, the risk of a permanent establishment for fulfillment centers or employees in the other country, and transfer pricing for goods crossing the border.

TYM coordinates treaty applications across both jurisdictions, aligning entity structures, intercompany pricing for inventory transfers, and filing positions to ensure treaty benefits are claimed correctly. Tariffs, duties, and landed cost accounting are tracked alongside tax positions. Missteps create double taxation or audit exposure in both countries simultaneously.

Dual-Agency Risk

Non-compliance in a cross-border ecommerce structure triggers consequences from both the IRS and CRA. IRS exposure includes transfer pricing adjustments on intercompany inventory transactions, withholding assessment on cross-border payments, and penalties for incorrect or late information returns. CRA exposure includes reassessment of intercompany transactions, Part XIII withholding tax on payments to non-residents, and penalties for late T2 or GST/HST returns. The risk compounds: an IRS adjustment to intercompany pricing triggers a corresponding CRA reassessment.

Case Study

From Inventory Chaos to Auditable Financials in 8 Weeks

DTC Supplement Brand · $3.8M Revenue · Shopify, Amazon, Wholesale, B2B

A DTC supplement brand scaled its revenue from $1.2M to $3.8M over 18 months across Shopify, Amazon, wholesale partners, and B2B. The problem: COGS didn't reconcile. Inventory was 15% higher on paper than in reality. Margin by channel was unknown. A Series A investor required audited financials. Timeline: 8 weeks.

Weeks 1–2: The diagnostic identified broken COGS accounting, inventory valuation errors, and multi-channel revenue gaps. Weeks 3–4: TYM rebuilt COGS using the weighted-average method, performed physical inventory count, reconciled to general ledger, and identified $180K in slow-moving and obsolete stock. Weeks 5–6: Shopify and Amazon revenue feeds integrated. Payment settlement tracked by platform. P&L reconciled. Weeks 7–8: Auditor-ready supporting schedules created. 12-month cash forecast built with working capital modeling. Financial statements completed.

Outcome: Clean audit. Inventory accurately valued. True margin by channel visible: Amazon at 18%, Shopify at 42%. The founder understood where to invest in marketing. Series A closed on time.

Risks of Incomplete Financial Infrastructure

Without proper CFO support, ecommerce companies face compounding financial risks that become increasingly expensive to resolve.

COGS doesn't reconcile to inventory

Margin is invisible. Decisions are made on wrong numbers. Investors discover the gap during diligence.

Cash crisis from working capital swings

Inventory timing and payment terms create $500K+ quarterly swings. Without a forecast, cash runs out before the next peak.

Multi-channel revenue blindspot

Amazon, Shopify, and wholesale report differently. P&L is a guess. Profitable channels are indistinguishable from cash sinks.

Sales tax exposure

Nexus in multiple states without proper tracking creates back-tax liability, penalties, and audit risk across jurisdictions.

Dual-agency cross-border risk

IRS transfer pricing adjustments on intercompany inventory transactions can trigger corresponding CRA reassessments — simultaneously.

FAQ: Fractional CFO for E-commerce

How is fractional CFO advisory different from bookkeeping for e-commerce?

Bookkeeping records transactions. CFO advisory integrates financial data with business decisions: connecting the inventory system to COGS accounting, aligning multi-channel revenue to cash position, forecasting working capital needs 90 days ahead, and guiding tax planning. TYM does not enter transactions; TYM oversees the system and drives strategy.

Does TYM manage inventory operations?

No. TYM audits inventory accounting, reconciles records to physical counts, and identifies obsolete or slow-moving stock. You manage the warehouse, fulfillment, and reorder decisions. TYM provides the data and recommendations to inform those decisions.

What if the e-commerce platform doesn't integrate with accounting?

TYM builds the integration. Most e-commerce platforms export daily or weekly revenue reports. That data is ingested into accounting, reconciliation is automated, and the monthly revenue-by-channel breakdown is created. If custom integration is needed, TYM advises that you execute or hire a developer.

How does TYM handle sales tax for multi-state ecommerce?

TYM maps nexus by state, tracks sales tax obligations by channel, and coordinates with your CPA on filing. Many states follow marketplace facilitator rules (Shopify/Amazon collect and remit). TYM clarifies your obligations and supports compliance.

Can TYM handle U.S.–Canada ecommerce?

Yes, it is a core competency. TYM coordinates U.S. tax (1120, sales tax by state, COGS for cross-border inventory) and Canadian tax (T2, GST/HST, tariff duty accounting). Cross-border inventory is tracked at landed cost, including duties and tariffs. CPAs in both jurisdictions are engaged.

How is the margin calculated by product and channel?

TYM tracks revenue by channel and SKU, COGS by inventory method, and direct fulfillment costs (labor, returns handling, packaging). Contribution margin = revenue minus COGS minus fulfillment costs. Profitability is visible per product and per channel.

What does a cash forecast for e-commerce include?

Revenue (by channel), inventory purchases (with payment terms), supplier payment dates, customer settlement delays (e.g., Amazon net-14), payroll, operating expenses, and seasonal swings. Base, upside, and downside scenarios are modeled. The outcome: clarity on when capital is needed.

Does TYM file tax returns?

No. Your CPA prepares and files. TYM prepares financial statements, projects tax liability, coordinates multi-jurisdictional requirements, and advises on timing and deductions. TYM works alongside your tax professional.

What does an e-commerce CFO engagement typically cost?

Retainer engagements range from $4,500 to $8,000/month, depending on complexity (channel count, inventory scale, cross-border activity). Project-based work (diagnostics, systems build, audit prep) ranges from $12,000 to $30,000+. TYM provides a proposal after the initial diagnostic.

When should an e-commerce company hire a fractional CFO?

When financial complexity outpaces internal capacity — common inflection points include scaling past $500K revenue, expanding to multiple channels, preparing for institutional investment, or managing cross-border operations. If COGS doesn't reconcile to inventory, the gap is already creating risk.

How long does it take to set up e-commerce financial systems?

Diagnostic and initial setup typically run 6–8 weeks. Ongoing monthly support continues as long as the engagement is active. Major projects (acquisition prep, debt facility setup) may require 3–6 week sprints.

Can TYM support acquisition or exit preparation?

Yes. Buyers want auditable inventory, clean revenue accounting, clear cash position, and defensible margins. TYM prepares a data room package that includes audited financials, inventory reconciliation, channel-level margin analysis, and tax compliance documentation.
