Borrowing money to stockpile inventory or hold extra cash reserves might seem like a safe move for eCommerce businesses, but it often backfires. Here’s why:
- Tied-Up Capital: Excess inventory locks up money that could be used for growth.
- High Costs: Holding inventory adds expenses like storage, insurance, and depreciation (20%-30% of inventory value annually).
- Discount Pressure: Overstocking often forces businesses to slash prices, cutting into profits.
- Interest Payments: Borrowing more than needed means paying unnecessary interest, reducing margins.
- Cash Flow Issues: Funds stuck in unsold inventory limit flexibility to respond to market changes.
Instead of relying on guesswork and overstocking, businesses should focus on precise demand forecasting, lean inventory practices, and flexible funding solutions like revenue-based financing to maintain healthy margins and improve cash flow.
Ecommerce Gross Margin: What’s a Good Range and How to Improve It
Hidden Costs of 'Just in Case' Funding
Hidden Costs of Just-in-Case Funding for eCommerce Businesses
Higher Interest Expenses
Interest payments eat directly into your profits. Borrowing more than you need means you're paying interest on funds that may sit idle or on inventory that doesn’t sell quickly. If the return on those borrowed funds falls below the interest rate, every dollar borrowed becomes a loss [1].
The problem gets worse over time. For example, a $15,000 loan at a 7.75% APR over 10 years could rack up more than $6,600 in interest, cutting deeply into your margins [5]. Wells Fargo explains it this way:
A higher loan amount might require a longer term to keep monthly payments manageable, which increases the amount you pay in interest and can increase the total cost of borrowing [5].
On top of interest, there are other fees to worry about. Origination fees, annual fees, and prepayment penalties can add thousands to your borrowing costs [5]. Then there are payment processing fees, which range from 2.5% to 3.5% plus $0.10 to $0.30 per transaction, and platform transaction fees, which can be anywhere from 0.15% to 2.0% [6][7]. When you combine these costs with a 60% increase in customer acquisition costs since 2021 and ad spend inflation running between 30% and 60% year-over-year [8], the financial pressure becomes overwhelming. Every dollar spent on interest is a dollar that could have been used to fuel your business’s growth.
And just like interest drains profits, tying up money in unused inventory can further limit your financial flexibility.
Capital Locked in Unused Inventory
Excess inventory is like cash frozen in time - money that could have been used to launch a new product, boost your best-performing ads, or enhance your website is instead sitting in a warehouse.
Holding too much stock isn’t cheap. It typically costs 20% to 30% of the inventory’s total value each year [4][6]. These costs include warehousing, insurance, and fulfillment fees. For Amazon FBA sellers, the issue gets worse during peak seasons, with storage surcharges spiking by as much as 30% [8]. What starts as a safety buffer can quickly turn into a financial burden.
When you overstock, the pressure to clear inventory builds. This often leads to heavy discounting, which eats directly into your margins. As Jay Kimelman, founder of High Rock Accounting, explains:
Discounts are like caffeine - they feel really good at the moment but after a little while you're going to feel that crash and it's going to catch up to you [8].
And if products sit too long, they risk becoming deadstock - obsolete items that can no longer be sold, meaning your entire investment in those products is lost.
Poor Cash Flow Management
The combination of high interest and excess inventory creates a cycle that drags on your cash flow. Borrowing extra might give you a sense of security, but when that money ends up in inventory that doesn’t turn over quickly, it leads to cash flow problems [8]. You’re stuck paying interest on loans while holding onto inventory that isn’t generating revenue.
This lack of liquidity makes it hard to adapt. If a supplier raises prices or advertising costs spike, you may not have the cash to respond. If a trending product emerges, you can’t act fast because your capital is tied up elsewhere. This mismatch between incoming and outgoing cash creates delays that can snowball into long-term financial challenges.
Operational costs pile up as well. Processing returns can cost between 20% and 65% of an item’s value [6]. And when you’re overstocked, you’re more likely to accept returns just to recover some cash. Meanwhile, acquiring new customers in eCommerce costs anywhere from $53 to $91 per customer [6]. That’s money you might not have on hand when your working capital is locked in excess inventory.
How 'Just in Case' Funding Affects Key Business Metrics
Lower Gross Margins
Overstocking often leads to steep discounts, ranging from 20% to 60%, which directly eats into gross margins [10]. When inventory sits idle for too long, it risks becoming obsolete, leading to write-offs and higher costs of goods sold (COGS) [11]. For instance, in Q3 2022, small and medium-sized businesses in the UK, New Zealand, and Australia reported a drop in their Gross Margin Return on Inventory (GMROI) due to holding record levels of stock [11]. Oliver Munro, an Inventory Management Specialist at Unleashed Software, highlights the significance of GMROI:
"This profitability metric [GMROI] shows how much profit inventory sales produce after covering inventory costs, and naturally, a higher GMROI is better, as it means each unit of inventory is generating a higher profit." [11]
While buying in bulk may reduce unit costs initially, these savings can quickly disappear when a declining GMROI forces businesses to offer deep discounts. These markdowns not only shrink gross margins but also reduce the revenue available to cover fixed costs, which further impacts contribution margins.
Reduced Contribution Margins
The contribution margin - what’s left after variable costs are deducted from revenue - is critical for covering fixed expenses and driving profits. Overstocking inflates variable costs such as warehousing, insurance, and logistics [9]. On top of that, businesses often face immediate interest payments on loans used to finance surplus inventory, which further compresses the contribution margin. Dennis Shirshikov, Head of Growth at GoSummer, explains the financial strain this creates:
"Lump sum loans also come with several downsides. They can create a financial burden due to the immediate need to repay the principal along with interest, often leading to increased financial stress if the business does not generate sufficient revenue quickly enough." [13]
As these costs pile up, they squeeze margins, leaving less to cover fixed expenses and ultimately reducing profitability.
Decreased Net Profit
Excess inventory ties up capital that could have been invested in growth initiatives like marketing, product development, or website improvements. This lost opportunity can significantly affect net profit. Additionally, higher operating expenses - such as long-term storage fees, which many Amazon sellers face - further erode net margins [16]. If demand drops or products become outdated, businesses may be forced to write off unsold inventory [12].
Katie Devoe, Owner and Co-Founder of CBD Nationwide, shared her experience with overstocking when her company found itself stuck with 10,000 units of multivitamins. After switching to leaner inventory practices, she saw a notable improvement:
"The switch to JIT was our response... by quarter's end, our financials reflected the change - a 20% cut in inventory holding costs." [17]
The combined effects of shrinking gross and contribution margins have a direct, negative impact on net profit. While a healthy net profit margin for eCommerce businesses hovers around 20%, many companies struggle to reach even 10% [14]. When you factor in interest on unused funds, storage fees for excess stock, and the cost of writing off obsolete products, even maintaining that 10% margin can feel like an uphill battle.

Better Financial Strategies to Protect Your Margins
Keeping your business financially secure while maintaining healthy margins is achievable with smarter funding and inventory strategies.
Use Demand Forecasting to Plan Ahead
Accurate demand forecasting takes the guesswork out of inventory planning, helping you stock items that actually sell. Modern analytics tools analyze historical data and seasonal trends to predict demand, ensuring your orders align with production schedules and free up precious capital [18][19][20].
Scenario planning can be a game-changer here. By using "what-if" models, you can determine the ideal buffer stock without overloading inventory [20]. For instance, if you expect a 20% spike in demand during the holiday season, these models can help you calculate the exact amount of additional inventory needed. This approach ensures you have enough stock to meet customer needs without overcommitting your cash. Such precise planning is the foundation of lean inventory practices.
Adopt Lean Inventory Practices
Lean inventory management prioritizes efficiency and reduces excess. A Just-in-Time (JIT) approach, where goods are received only as they're needed, minimizes waste, lowers storage costs, and keeps operations in sync with actual demand [15]. Overstocking, on the other hand, ties up capital and inflates costs unnecessarily [22].
By adopting lean inventory practices, you free up cash that can be redirected into growth opportunities. This method not only reduces waste but also ensures that your resources are available for strategic investments.
Revenue-Based Financing with Onramp Funds
Building on demand forecasting and lean inventory practices, consider a funding model that adapts to your sales cycle. Traditional lump-sum loans often lead to overborrowing - locking up capital and racking up interest - or underfunding, which stifles growth. Revenue-based financing offers a more flexible solution by providing access to capital as your business needs it [21].
"Just-in-time funding ensures that sellers can maintain adequate inventory levels to meet customer demand." – Gazbia Majdi, Operational Manager, ShipGlobal [21]
Onramp Funds, for example, aligns repayment with your sales performance. During high sales periods, you repay more, and during slower times, you repay less. This flexibility keeps your cash flow active and avoids tying up funds in excess inventory. By reducing interest costs and maintaining liquidity, revenue-based financing protects your margins while supporting sustainable growth [21].
Considering that 82% of small businesses fail due to poor cash flow management [21], having a funding partner that aligns with your business's rhythm can be the key to long-term success.
Conclusion: Plan Your Funding for Long-Term Financial Health
Over-relying on "just in case" funding can quietly erode your profits. The hidden costs - like higher interest rates, money tied up in unused inventory, and poor cash flow management - can take a toll on your bottom line month after month. Considering that cash flow problems are one of the top reasons small businesses fail [1], safeguarding your financial health is non-negotiable.
Instead of reacting to financial challenges, take a proactive approach to borrowing. Shift away from stockpiling debt and adopt lean inventory practices that align your funding with actual sales needs. This way, your cash remains flexible and ready to fuel growth opportunities [1]. To complement this, explore financing solutions that work in harmony with your sales cycles.
One such solution is revenue-based financing, which adjusts repayment based on your real-time sales performance. During busy seasons, you pay more when revenue is strong, and during slower times, your payments decrease, helping you maintain working capital. Onramp Funds offers this kind of tailored financing to meet the dynamic needs of sellers [2].
The stakes are high in today’s competitive landscape. The U.S. eCommerce market alone is projected to exceed $1.1 trillion in 2024 [3]. The businesses that succeed are those that approach funding with a clear plan. By relying on real-time sales data rather than instinct, you can make smarter decisions about capital, ensuring sustainable growth without compromising your profits or equity [2].
To protect your margins and cash flow over the long run, align your funding strategy with your business cycle. Set specific goals for every dollar you borrow, regularly review your financial health, and partner with lenders who understand the unique cash flow dynamics of online businesses. By adopting demand forecasting and lean practices, as discussed earlier, you’ll create a financial foundation that supports both stability and growth.
FAQs
How does accurate demand forecasting improve cash flow for eCommerce businesses?
Accurate demand forecasting is a game-changer for eCommerce businesses. It helps align inventory purchases with actual market needs, cutting down on excess stock and freeing up cash that might otherwise sit idle in unsold products. By steering clear of over-ordering, businesses can slash storage costs, reduce handling expenses, and avoid tying up capital unnecessarily. This extra liquidity can then be channeled into growth-oriented initiatives like marketing campaigns, launching new products, or ensuring timely supplier payments.
But the benefits don’t stop there. Sharp forecasting also helps prevent stockouts - those frustrating moments when products are unavailable, leading to missed sales and costly last-minute restocking. By analyzing historical sales data, setting safety stock thresholds, and keeping a close eye on inventory performance, businesses can strike the perfect balance. This not only keeps cash flow predictable but also smooths out the entire financial cycle. With fewer financing hiccups and better inventory management, companies can build a solid foundation for sustainable growth.
Why is lean inventory management better than 'just-in-case' funding for eCommerce businesses?
Lean inventory management is a smart way for eCommerce businesses to protect their profit margins by cutting unnecessary costs. The idea is simple: keep only the stock you truly need. Strategies like demand forecasting and Just-in-Time (JIT) ordering help you avoid the hefty expenses of holding excess inventory, which can add up to 20–30% of annual costs. This method also reduces risks like product obsolescence, markdowns, and the added burden of extra storage or insurance fees.
Another big win? Lean inventory reduces the need for "just-in-case" borrowing to manage cash flow gaps. This means you can sidestep the 2–8% interest rates or fees that often come with inventory loans. With less money tied up in unused stock, you’ll have more flexibility to invest in growth opportunities. Tools like real-time demand tracking and automated reorder points also help you stay nimble, making it easier to avoid stockouts and keep your customers happy. Ultimately, lean inventory keeps operations efficient, protects your margins, and builds a more adaptable business model.
How does revenue-based financing support long-term profitability?
Revenue-based financing lets your repayment scale with your sales. When your revenue dips, your payments shrink too, giving you breathing room to manage cash flow without the strain of fixed monthly obligations.
This model offers a smart alternative to high-interest loans or sacrificing equity. It helps you keep more of your profits while still securing the funds you need to expand your business at a steady pace.
