Update: We originally published this article in 2012 with three signs that a business might need an inventory management specialist. The role still matters, but there is no single revenue or order-volume threshold that determines when to hire an eCommerce inventory manager. The better question is whether inventory has become too complex to manage without a clear owner.
Inventory responsibilities often begin informally. A founder, warehouse employee, operations manager, or purchasing team may each handle part of the process. That can work while the catalog is small and inventory moves through one location.
As the business adds products, suppliers, sales channels, warehouses, and order volume, those responsibilities become harder to divide. Receiving may be handled differently by each employee. Purchase decisions may depend on memory. Stock discrepancies may be corrected without anyone investigating why they occurred.
An inventory manager gives the process a clear owner. That person may not perform every inventory task, but they establish the standards, monitor accuracy, investigate problems, and make sure the business has reliable information for purchasing and fulfillment.
What Does an Inventory Manager Do?
An inventory manager oversees the processes used to receive, store, count, replenish, adjust, and report on inventory. The exact responsibilities depend on the business, but the role may include:
- Establishing receiving and storage procedures
- Monitoring inventory accuracy
- Reviewing low-stock and replenishment needs
- Managing purchase orders and supplier activity
- Organizing cycle counts
- Investigating stock discrepancies
- Coordinating warehouse transfers
- Managing returns and damaged inventory
- Reviewing inventory reports and operational trends
In a small business, these responsibilities may belong to an operations manager or warehouse lead. A larger company may have an inventory manager supported by purchasing, receiving, and warehouse employees.
The job title matters less than having one person who is accountable for the overall process.
1. Inventory Work Is Pulling Employees Away From Their Main Roles
One of the clearest signs is that inventory work has become a constant interruption. Employees may spend increasing amounts of time searching for products, checking stock manually, reconciling spreadsheets, correcting quantities, or asking suppliers when inventory will arrive. A founder may be reviewing purchase orders late at night because no one else owns replenishment. Customer service may be walking through the warehouse to confirm whether an item is actually available.
These tasks may seem small individually, but together they can take significant time away from fulfillment, customer support, purchasing, marketing, and other responsibilities.
An inventory manager can centralize those decisions and create a consistent process for handling them. The goal is not simply to move work from one employee to another. It is to reduce the amount of avoidable work created by unclear procedures and unreliable records.
2. Stock Discrepancies Are Becoming Routine
Occasional inventory differences happen in nearly every operation. The problem begins when inaccurate quantities, missing products, and fulfillment mistakes become normal. Common warning signs include:
- Products appear available but cannot be found
- Employees regularly adjust quantities without knowing why
- Orders are canceled because stock records were wrong
- Similar SKUs are frequently confused
- Returned products are mixed with sellable inventory
- Inventory differs between warehouses or sales channels
- The same discrepancies appear during every count
When these issues repeat, the business needs someone to investigate the process rather than only correct the final number.
For example, a missing product may point to a receiving problem, an unclear storage location, a picking mistake, or an unrecorded transfer. Changing the quantity in the system may resolve the immediate discrepancy, but it does not prevent the same problem from happening again.
Our guide to preventing misplaced inventory explains how receiving, location management, cycle counting, and consistent SKUs can make stock easier to find and trust.
3. Purchasing Decisions Depend on Guesswork
Inventory management is not only about knowing what is on the shelf. It also affects what the business buys next.
Without a clear owner, purchase decisions may be based on whichever employee notices that stock looks low. Products may be reordered too late, purchased in excessive quantities, or overlooked because the team does not have a consistent review process. An inventory manager can bring more structure to replenishment by reviewing:
- Current available inventory
- Open customer orders
- Incoming purchase orders
- Supplier lead times
- Sales velocity
- Seasonal demand
- Safety stock requirements
- Products that are overstocked or moving slowly
The person in this role does not need to predict demand perfectly. They do need enough visibility to make decisions based on current information rather than memory or urgency.

4. Inventory Procedures Vary by Employee
A growing business may have several employees receiving shipments, moving stock, handling returns, or making adjustments. If each person follows a different process, inventory accuracy becomes difficult to maintain.
One employee may place new stock on the shelf before confirming the quantity. Another may receive everything listed on the purchase order even when part of the shipment is missing. Returned products may go directly back into available inventory without inspection.
An inventory manager can establish repeatable procedures for the points where inventory changes:
- Receiving supplier shipments
- Assigning storage locations
- Moving products between locations
- Picking and packing orders
- Processing returns
- Recording damaged inventory
- Completing cycle counts
- Approving stock adjustments
Documented procedures also make training easier as the team grows. New employees do not have to learn inventory management through informal instructions or trial and error.
5. No One Is Accountable for Inventory Accuracy
Inventory problems often remain unresolved when responsibility is spread across several departments. The warehouse may assume purchasing owns the quantities. Purchasing may assume receiving updated them. Customer service may identify a problem but have no process for reporting it. Everyone touches the inventory, but no one owns the final accuracy of the records.
Giving one person responsibility does not mean blaming them for every error. It means creating a clear path for reviewing discrepancies, improving procedures, and deciding which issues require attention. The inventory manager should be able to answer questions such as:
- Why did this quantity change?
- Which products are frequently miscounted?
- Are suppliers delivering complete orders?
- Which locations create the most picking errors?
- Are returns being processed correctly?
- Which products need to be reordered?
- Is inventory synchronized across sales channels?
That accountability helps turn inventory data into something the business can use rather than something employees constantly question.
6. The Operation Is Becoming More Complex
A business may need dedicated inventory oversight even if its overall order volume is still manageable. Complexity can increase when the company adds:
- More SKUs or product variations
- Multiple warehouses
- Additional suppliers
- Kits and bundles
- Wholesale and retail channels
- Dropshipping workflows
- International fulfillment
- Seasonal inventory
- Products with long supplier lead times
Each addition creates more places where inventory information can become disconnected. Review Ordoro’s integrations to see the sales channels, carriers, suppliers, and other systems that can connect with the platform.
That is why hiring decisions should be based on operational complexity and recurring problems rather than one revenue threshold.
Does Software Replace an Inventory Manager?
Inventory software and an inventory manager solve different parts of the problem. Software can centralize quantities, orders, purchase orders, warehouses, and product information. It can reduce manual updates and give the team better visibility into what is happening.
Businesses can also compare Ordoro’s available Shipping, Inventory, and Dropshipping apps to choose the tools that match their current operation. Explore Ordoro’s apps and pricing.
However, software does not decide why a discrepancy occurred, whether a supplier is consistently under-delivering, how returned inventory should be handled, or which warehouse procedure needs to change. The inventory manager owns the process. The software gives that person reliable information and tools to manage it.

Businesses still relying heavily on manual files may also benefit from reviewing the signs that they have outgrown spreadsheet inventory management.
Inventory Manager FAQs
When should a small business hire an inventory manager?
A small business may need an inventory manager when stock problems are recurring, inventory work is consuming too much employee time, or no one is clearly responsible for receiving, replenishment, counting, and accuracy.
Can an operations manager handle inventory?
Yes. In smaller companies, an operations manager, warehouse manager, or purchasing lead may own inventory responsibilities. The important part is assigning clear accountability and enough time to manage the process properly.
What skills should an inventory manager have?
An inventory manager should understand receiving, warehouse organization, purchasing, cycle counting, inventory reporting, and fulfillment workflows. Strong problem-solving and communication skills are also important because inventory issues often involve several teams and suppliers.
Give Your Inventory Process a Clear Owner
As an eCommerce business grows, inventory can no longer be managed only when someone has time to check it. A clear owner helps the business create consistent procedures, investigate discrepancies, make better purchasing decisions, and keep inventory information dependable.
