The Controller’s First 30 Days: What We Look For in Your Ecommerce Business

Posted on February 23rd, 2026.

Bringing a fractional controller into your ecommerce business isn’t about fixing everything overnight. It’s about gaining clarity... quickly and intentionally.

For ecommerce founders generating $500K or more in annual revenue, complexity tends to arrive faster than structure. Inventory grows, ad spend increases, platforms multiply, and suddenly the numbers feel harder to trust. Revenue may look strong, but cash feels tight. Margins fluctuate without a clear explanation. Decisions are made, but confidence lags behind.

The first 30 days with a fractional controller — or even a fractional CFO providing strategic accounting services — are designed to change that.

Rather than jumping straight into strategy, we focus on understanding what’s really happening beneath the surface. That clarity becomes the foundation for better decisions, healthier cash flow, and sustainable growth.
Here’s what that first month typically looks like and why it matters.

First: We Assess the Financial Foundation

Before recommendations come understanding. The first step is evaluating whether the financial foundation can be trusted.

For e-commerce businesses, this means answering critical questions:

• Are the books current and fully reconciled?
• Do financial reports align with what’s happening in the bank and in the store
• Can margins be relied on month to month?
• Are there proper controls around cash collections, refunds, and disbursements?

E-commerce accounting often breaks down quietly. Inventory purchases, returns, platform fees, and ad spend can distort financials if systems aren’t set up correctly. If the foundation isn’t solid, scaling only amplifies the confusion.

This is where structured bookkeeping services and accounting controller oversight become critical. If the foundation isn’t solid, scaling only amplifies the confusion.

Our goal in this phase is simple: determine whether the numbers reflect reality. Without that confidence, every decision from pricing to inventory buys becomes a guess.

Next: We Identify Red Flags Early

Red flags tend to surface quickly, especially in growing e-commerce businesses. Common ones include:

• Stores that appear profitable but consistently struggle with cash flow
• Products with strong sales volume but weak or negative margins
• Inconsistent gross margins caused by misclassified costs or untracked fees
• “Temporary” manual workarounds that became permanent processes

These aren’t signs of failure. They’re signals that the business has outgrown its financial systems and may need more advanced account consulting and strategic accounting services to support growth.

Left unaddressed, these issues compound. Cash pressure increases, decision-making slows, and growth starts to feel risky instead of exciting. Identifying these patterns early helps prevent expensive corrections later.

Then: We Focus on Quick Wins That Create Momentum

Clarity often reveals opportunities for immediate improvement. These quick wins aren’t cosmetic, they usually free up cash or remove friction fast.

For e-commerce founders, early wins often include:

•  Cleaning up expense classifications to reveal true product and channel margins
• Identifying pricing or discounting issues that erode profitability
• Improving billing, payout timing, or refund visibility
• Simplifying reports so leadership can actually use them
• A rolling 13-week cash flow forecast

These changes don’t require a full overhaul. They create breathing room. When founders see improvements quickly, confidence builds and that momentum supports deeper strategic work often guided by a fractional CFO or experienced accounting controller.

Finally: We Build Toward a Long-Term Financial Strategy

Once the numbers are clear and reliable, strategy becomes practical instead of theoretical.

This phase focuses on:

• Establishing a consistent monthly financial rhythm
• Defining e-commerce-specific KPIs that reflect how the business actually makes money
• Building cash flow visibility tied to inventory cycles and ad spend
• Aligning growth plans with financial reality, not assumptions

The objective isn’t perfect reports. It’s predictable decision-making. When founders understand what’s happening and why, they stop reacting to surprises and start steering intentionally.

What Most Founders Don’t Expect

A fractional controller’s first 30 days aren’t about control. They’re about confidence.

Confidence in your margins. Confidence in your cash position. Confidence that when you decide to scale, the numbers will support it.

For e-commerce businesses at or beyond $500K in revenue, that confidence is what separates sustainable growth from constant financial stress and it’s why many founders eventually transition from basic bookkeeping services to higher-level accounting services and fractional CFO support.

If someone reviewed your financials today, what do you think they’d find first: clarity or questions?
