Small business owners wear many hats. They are HR managers, marketing executives, and, of course, the Chief Financial Officer of their business. Most small business owners either manage their books independently or hire a bookkeeper to keep their finances in order. 

While this seems most practical, it can lead to avoidable mistakes that significantly impact a company’s bottom line. This may lead to inadequate cash flow, debt, and more taxable income than you’d like on your books. The best way to prevent these mistakes is to seek professional guidance who advises an internal stakeholder. That way, you are armed with the expertise and tools to give you accurate data and peace of mind. 

Mistake 1: Improperly Tracking Inventory

According to CNBC, businesses lose more than $1.75 trillion yearly due to overstocks, returns, and out-of-stock products. These discrepancies result from a gap between the items a business has on hand and the number of items recorded in its inventory system. Improperly tracking your inventory can hurt your business in other ways. This includes incorrect financial reporting, lost shareholder confidence, and cost control issues (including overstocking and understocking). Depending on the industry, these discrepancies can further disrupt production schedules and procurement processes. In the worst cases, these mistakes can turn into expensive tax penalties and legal issues. 


The best way to prevent these errors is to implement a system for lot tracking and cycle counting. Lot tracking assigns a batch number to products to monitor expiration dates, and control recalls. Cycle counting involves regularly checking a smaller inventory section to ensure physical counts match system records. This not only reduces waste and improves inventory valuation but also leads to more accurate financial reporting.

Mistake 2: Miscalculating Production Labor Costs

Material and labor costs are rising, so understanding the true cost of manufacturing or procurement costs is key to realizing profit. When costs fluctuate, your business needs real-time visibility into how changes impact the margin on each item so that you can adjust pricing or expenses. Understanding margins also allows your business to focus investment on higher-margin items. Often, the biggest hurdle to understanding production costs is labor costs. Inaccurate labor costs can lead to misallocated expenses and inaccurate COGS (cost of goods sold)

Direct labor costs are directly tied to production and output (e.g., factory workers assembling products or the time it takes to pick and pack orders). Indirect labor costs are not directly involved in production (e.g., warehouse security). The distinction is important as the two types must be accounted for differently. The cost of direct labor is charged to all items produced within the reporting period, according to the hours of labor used in the production process. Indirect labor is charged to expenses in the reporting period. 

If these two labor types are not accounted for properly, inaccurate COGS metrics can result, which can have a domino effect on your financial statements. Inaccurate COGS impedes your understanding of the cost of producing or securing goods, leading to ineffective pricing, inaccurate production levels, and poor resource allocation. 

Involve a bookkeeping expert to ensure that labor types are categorized correctly. They can move beyond categorization and improve cost analysis, advise on pricing, and improve the accuracy of your financial statements overall.  LedgerFi is a bookkeeping and tax advisory solution founded by tax professionals who help empower and grow small businesses. With the right team behind your back, you can easily avoid these common accounting mistakes. 

Mistake 3: Underestimating or Underreporting on Taxes

Self-employed entrepreneurs, sole proprietors, partners, and S corporations must make quarterly tax payments based on their estimated tax bill for the year. Most businesses won’t know the exact amount, but making an accurate, data-driven decision will avoid fees and penalties due to underestimating or underpaying. If the IRS has reason to believe the business is “unreasonably careless” in reporting its income, or if the taxes owed are significantly understated, the business may be hit with penalties of up to 20%. If the IRS believes an attempt was made to defraud the government, fines can be as high as 75%. 

Mistake 4: Not Separating Profit Margins by Sales Channels

Many businesses mistakenly use a single profit margin figure, including all sales channels, which can be misleading. Different sales channels, like direct sales teams or online marketplaces, often have varying costs. To get a clear picture of profitability, tracking revenue and costs for each sales channel is crucial. This allows you to compare their performance, understand how much it costs to acquire customers through each channel, and allocate resources more effectively. Separating profit margins by sales channels allows you to maximize your overall profitability and make data-driven decisions about your sales strategy. Partner with an accounting partner that uses powerful reporting tools and professional expertise to guide your business decisions.

Mistake 5: Not Getting the Right Help

Many small business owners lack the financial expertise to handle complex accounting tasks but don’t engage with a professional bookkeeper because of cost. Businesses may overlook the need for professional help because they mistakenly believe they’re too small to justify the investment. While it may be tempting to hire a generalist bookkeeper, these hires are rarely licensed or equipped to deal with complex accounting issues, especially regarding taxes. 

Everybody makes mistakes, but as a small business, you can’t afford to make mistakes regarding your finances. Luckily, these accounting mistakes are easy to avoid with the right team and tools. Speak with LedgerFi and get things right – the first time.

“The core of maturity, that I see, is starting with a unified view of inventory. I’ve got to be able to accurately represent what do I have, make sure that I know where it’s located so I can get it to my customers quickly.”

— Troy Graham, Descartes

What is the first thing I should fix if I want to scale operations?

Start with a unified view of inventory. The core of maturity starts with being able to accurately represent what you do have and make sure that you know where it’s located to get it to customers quickly. Without a unified view across your warehouses, 3PLs, and vendors, you cannot make the best decisions because you don’t have the best information at hand.

With Inventory Visibility, Businesses Can Make Smarter Allocation Decisions

Once inventory is centralized, businesses can move from reactive updates to intentional allocation. They can decide how much inventory to expose to each channel, when to use buffers, which marketplaces need extra protection, and how seasonality or campaign performance influence availability.

Once I know what inventory I have, how should I decide where to make it available?

Inventory allocation should reflect where orders are coming from, where marketing is working, and which channels carry the most risk. Once you know what you have and where it is located, you can think more strategically using centralized inventory to make prioritization happen automatically. One fertilizer company lost a little over 5,000 orders in one weekend because someone manually uploaded the wrong available inventory to Amazon.

Better Inventory Data Improves Planning, Purchasing, and Growth Bets

Better visibility turns inventory data into a planning tool. With insight into sales velocity, inventory levels, vendors, and channel performance, businesses can make more informed replenishment decisions, avoid overbuying, and test new product lines or vendor-supplied inventory without taking on unnecessary risk.

“You have to have unified inventory to know how to price your products just at that basic level. I can’t price my products if I don’t know the true cost to get it.”

— Mike Bernico, Flxpoint

How does better inventory data help me make smarter buying decisions?

It lets you measure whether your plan is working before you commit more capital. A key question becomes: “Did my plan work? Am I overleveraged in one place or another?” Centralized systems can also help businesses test new product lines or vendor relationships by looking at sales velocity by channel, allowing them to take risks in a calculated and measured way.

Intelligent Order Routing Turns Inventory Complexity Into Automation

Once inventory and supplier data are reliable, businesses can automate fulfillment decisions. Orders can be routed based on cost, speed, margin, location, warehouse priority, vendor fallback, split-shipment rules, or customer expectations. This helps hybrid fulfillment scale because every order does not need a manual review.

How do I decide the best way to fulfill each order?

There is no single answer, which is why order routing needs to account for the context of each order. Intelligent order routing is not just sending an order to someone who has stock; it is taking each and every order and treating it like its own unique use case. Depending on the order, the business may prioritize speed, margin, an internal warehouse, vendor fallback, or preventing split shipments.

Supplier Inventory Sync Extends Inventory Beyond the Four Walls

For hybrid fulfillment to work, supplier inventory needs to become part of the operating model. Supplier sync does not always require advanced technology; it can happen through automated files, FTP, email, APIs, EDI, or ecommerce storefront integrations. The key is replacing manual updates with automated, reliable supplier data.

Can supplier inventory really be treated like part of my own inventory?

Yes, but the goal is not necessarily to force every supplier into a complex integration. Real-time supplier sync can be defined as any way to get an automated update from a supplier, such as Google Sheets, email, FTP, API, EDI, or ecommerce storefront connections. The key is that accurate supplier stock is foundational. If you don’t have an accurate view of what is in stock with your suppliers, you cannot tell your sales channel accurately what’s available.

Exception-Based Workflows Keep Humans Focused Where They Matter

Automation does not remove people from the process. Mature operations let technology handle the routine majority while humans focus on exceptions, such as high-value orders, fraud risk, compliance requirements, restricted products, export rules, or unusual fulfillment scenarios.

If my business has special cases, can automation still work?

Yes. The point is not to automate every possible decision; it is to automate the routine work and surface the exceptions. Businesses should not have to look at every single order. Instead, technology can highlight high-value orders, risky locations, or compliance requirements. The goal is to take care of the 80% of workflows that are obvious while still allowing human review when specific exceptions arise.

The Right Inventory Technology Should Fit the Business, Not Overwhelm It

Software decisions should be based on business fit, not popularity, feature volume, or broad “all-in-one” promises. Growing ecommerce businesses should identify their highest-impact bottleneck, prioritize what matters now, and choose technology that is right-sized but flexible enough to support future phases of growth.

How should I choose software without overbuying or picking the wrong system?

Start with your priorities, not the biggest feature list. Avoid an all-in-one system that claims to “do everything under the sun” and look for a “best of breed approach” with systems that can scale as you add channels or vendors. The practical advice is to stack rank what matters now, make sure the system can support future phases, and choose technology that fits your business rather than overwhelming it.

Ecommerce Fulfillment Operations FAQ

What Is Ecommerce Fulfillment Operations?

Ecommerce fulfillment operations are the processes that move an online order from purchase to delivery. This includes managing inventory, syncing product availability across channels, routing orders to the right warehouse, 3PL, supplier, or vendor, and making sure the customer receives the right product on time. As discussed in the webinar, fulfillment is no longer limited to “what’s in my warehouse these days”; growing businesses may rely on internal warehouses, 3PLs, marketplace fulfillment services, and supplier inventory at the same time.

What Are Ecommerce Fulfillment Operation Examples?

Examples of ecommerce fulfillment operations include updating inventory across Shopify, Amazon, Walmart, and other sales channels; allocating inventory to specific marketplaces; sending orders to an internal warehouse, 3PL, or vendor; syncing supplier inventory through files, APIs, EDI, email, or FTP; replenishing warehouse stock based on sales velocity; and flagging exceptions such as high-value orders, compliance requirements, or restricted products. In the webinar, the speakers also discussed hybrid fulfillment examples where a business may fulfill some products from its own warehouse and use vendors as a fallback or extension of available inventory.

How Can I Track My Inventory at an Ecommerce Fulfillment Center?

The best way to track inventory at an ecommerce fulfillment center is to create a unified inventory view that shows what is available, where it is located, and how that inventory connects to each sales channel. That means tracking inventory across internal warehouses, fulfillment centers, 3PLs, marketplace fulfillment programs, and supplier locations instead of relying on disconnected spreadsheets. The webinar emphasized that businesses need to “accurately represent” what they have and know where it is located so they can get products to customers quickly.

How Can I Connect My Inventory to My Supplier?

You can connect supplier inventory through several methods, depending on what the supplier supports. The webinar discussed low-tech and advanced options, including automated Excel or CSV files, Google Sheets, email updates, FTP servers, APIs, EDI, and direct connections to ecommerce storefronts such as Shopify, BigCommerce, or Magento. The key is to ask suppliers how they share inventory today, then use a system that can automate that data flow instead of manually copying supplier inventory into spreadsheets.

What Is Ecommerce Order Routing?

Ecommerce order routing is the process of deciding where an order is fulfilled from after a customer buys. In a simple operation, every order may go to one warehouse. In a more complex or hybrid fulfillment model, the best fulfillment source may depend on inventory availability, shipping speed, cost, margin, customer location, warehouse priority, vendor fallback rules, or whether the order should be split. The webinar described intelligent order routing as treating each order like its own use case, so businesses can automate the best fulfillment decision without manually reviewing every order.
