Stock control with Xero
Track items and see what's selling with Xero's stock control software
Stock management is the process of ordering, storing, tracking and controlling your business's inventory. It covers everything from knowing how many units you have on hand to deciding when and how much to reorder.
For any business that sells physical products, stock management sits at the centre of daily operations. Without it, you risk running out of popular items, over-ordering slow-moving products, or losing track of what you actually have in storage.
Good stock management gives you a clear picture of what's coming in, what's going out, and what's sitting on your shelves. That visibility helps you make smarter purchasing decisions, reduce waste and keep your cash flow healthy.
Why stock management matters for small businesses
When you're running a small business, every rand counts. Effective stock management directly affects your bottom line by helping you avoid two costly problems: having too much stock and having too little.
Overstocking ties up cash you could use elsewhere, increases storage costs, and raises the risk of products expiring or becoming obsolete. Understocking means lost sales, frustrated customers and potential damage to your reputation.
Weak stock control also invites shrinkage from theft, damage and miscounts, which is a real cost for any retailer. One estimate cited in the South African Journal of Economic and Management Sciences puts shrinkage at around 2.6% of sales, a direct drain on already thin margins.
Strong stock management also saves you time. Instead of scrambling to check stock levels or placing last-minute rush orders, you can plan ahead with confidence. Accurate stock data makes your financial reporting more reliable too, so your balance sheet reflects reality and your cash flow picture becomes clearer, making tax time far less stressful.
Stock management vs stock control
The terms stock management and stock control are often used interchangeably, but they describe slightly different things. Knowing the distinction helps you set up the right processes for each.
Stock management is the broader strategy. It covers planning, forecasting demand and deciding what to order, when to order it and how much to hold. Stock control is the day-to-day side: counting stock, receiving deliveries, recording movements and reconciling what your records say against what's physically on the shelf. You need both, and strong stock control is what keeps your wider stock management decisions accurate.
Types of stock
Not all stock is the same. Understanding the different categories helps you manage each one appropriately and keep your operations running smoothly.
Raw materials are the basic components you buy to create your finished products. For a bakery, that's flour, sugar and eggs; for a furniture maker, it's timber and hardware. Tracking raw materials means you don't halt production because a key ingredient ran out.
Work in progress (WIP) refers to items that are partway through your production process but aren't yet ready to sell. Monitoring WIP helps you spot bottlenecks and forecast when finished goods will be available.
Finished goods are completed products ready for sale. These are the items your customers see and buy, and keeping the right amount on hand is the core challenge of stock management.
Consumables are supplies your business uses during operations but doesn't sell directly, such as packaging materials, cleaning products or office supplies. They don't generate revenue, but running out of them can slow your business down.
Stock management methods
There's no single approach to managing stock. The method you choose depends on your business type, product shelf life and how much complexity you're comfortable with, and many businesses combine methods for different product categories.
Just-in-time (JIT)
Just-in-time means ordering stock only when you need it, right before it's required for production or sale. This approach minimises storage costs and reduces waste, but it relies on reliable suppliers and accurate demand forecasting. If a shipment is delayed, you could face stockouts.
First in, first out (FIFO)
FIFO makes sure the oldest stock gets sold or used first. It's essential for perishable goods like food, cosmetics or medicines, and it helps prevent items from sitting too long and becoming outdated. The opposite method, last in, first out (LIFO), is not permitted under the International Financial Reporting Standards (IFRS) that guide South African reporting, so most local businesses use FIFO or the weighted average method.
ABC analysis
ABC analysis sorts your inventory into three categories based on value. "A" items are your highest-value products that generate the most revenue, "B" items fall in the middle, and "C" items are your lowest-value, highest-quantity products. This method helps you focus your attention and resources where they'll have the biggest impact.
Safety stock
Safety stock is extra inventory you keep on hand as a buffer against unexpected demand spikes or supply chain delays. Setting the right level means balancing the cost of holding extra inventory against the risk of running out, which is especially useful when supplier lead times are unpredictable.
Economic order quantity (EOQ)
EOQ is a formula that works out the ideal order quantity to minimise your total inventory costs, including ordering and holding costs. It works best when demand is relatively stable and predictable, and it can save you money over time by reducing both excess stock and frequent reorders.
Minimum stock level
Setting a minimum stock level means defining the lowest quantity of each product you're willing to hold before triggering a new order. This simple method suits small businesses with straightforward product lines: when stock dips below the minimum, you reorder a predetermined amount.
Periodic vs perpetual inventory
Periodic inventory involves counting your stock at set intervals, such as weekly or monthly. It's simpler to manage but gives you less real-time visibility. Perpetual inventory tracks stock continuously, updating levels every time a sale or delivery happens; it requires software but provides much more accurate, up-to-date data.
How to measure stock management
A few simple measures show you whether your stock is working for you or against you. Tracking them over time helps you spot overstocking, weak demand and cash tied up on the shelf.
- Stock turnover measures how many times you sell and replace your inventory over a given period, so a higher rate generally signals efficient selling while a low rate may point to overstocking or weak demand.
- Stockout rate is the share of items that are out of stock at a given time, and a rising rate warns that you're losing sales to empty shelves.
- Days sales of inventory estimates how many days it takes to sell your average stock, giving you a feel for how quickly cash moves through your inventory.
How to set up a stock management system
Getting started with a stock management system doesn't have to be complicated. These steps help you build a solid foundation, even from scratch, and it's worth reading our guide to creating an inventory management system for a deeper look.
1. Audit your current stock
Before you can manage your inventory well, you need to know exactly what you have. Do a full physical count of every product, raw material and consumable, recording quantities, locations and conditions. This baseline is essential for everything that follows.
2. Organise and categorise your products
Group your stock into logical categories, whether by product type, supplier or sales velocity. Assign each item a unique identifier or SKU (stock keeping unit), because consistent naming makes it much easier to track items, spot trends and run reports.
3. Choose your stock management method
Based on your business type and product range, pick the method that fits best. A cafe might use FIFO to keep ingredients fresh, while a retailer with thousands of SKUs might benefit from ABC analysis, and you can combine methods for different categories.
4. Set reorder points and quantities
For each product, decide the minimum stock level that should trigger a reorder, and how much to order each time. Factor in supplier lead times, seasonal demand and any safety stock you want to maintain, so you prevent both stockouts and overstocking.
5. Pick the right software
Spreadsheets can work when you're starting out, but they become unreliable as your business grows. Look for stock management software that integrates with your accounting so inventory data flows straight into your financial records, and choose a cloud-based tool so you can check stock levels from anywhere.
6. Train your team and set clear processes
A stock management system is only as good as the people using it. Make sure everyone involved understands how to record stock movements, process deliveries and flag discrepancies, and document your processes so they stay consistent as your team changes.
7. Review and adjust regularly
Stock management isn't something you set up once and forget. Schedule regular reviews to compare actual stock levels against your records, adjust reorder points as demand changes and refine your approach, with monthly or quarterly reviews working well for most small businesses.
Stock management software
Many small businesses start out managing stock with spreadsheets. While they can work initially, the right inventory management software makes a big difference as you grow, because once you have more than a handful of products, spreadsheets quickly become a liability.
Spreadsheets rely on manual data entry, so they're prone to human error. They can't update in real time, which means what you see might not reflect what's actually on your shelves, and they don't connect to your other business tools, forcing you to duplicate work across systems.
Dedicated stock management software solves these problems. Look for a solution that offers real-time stock tracking, automatic reorder alerts and integration with your accounting platform. Reporting on stock turnover, valuation and sales trends is valuable too, giving you the data behind better decisions.
Cloud-based software is especially useful for small businesses. It lets you and your team access stock data from any device, updates sync automatically so everyone works from the same numbers, and backups and security are handled for you. Platforms like Xero connect with inventory apps so your stock data flows straight into your accounting records without manual re-entry.
Common stock management mistakes to avoid
Even with good intentions, it's easy to fall into habits that undermine your stock management. Here are some of the most common pitfalls to watch for.
- Skipping regular stock counts lets discrepancies from theft, damage or data entry errors build up silently, so verify your records physically rather than trusting the system alone.
- Overstocking "just in case" might feel safe, but it ties up cash, increases storage costs and risks products becoming obsolete before you sell them.
- Ignoring slow-moving stock drains your resources, so review your inventory regularly and act on items that aren't selling, whether that's discounting, bundling or discontinuing them.
- Using disconnected systems for stock, sales and accounting makes errors and delays almost inevitable, whereas integrated systems keep everything in sync.
- Skipping demand forecasting leads to repeated cycles of overstocking and stockouts, when even simple forecasting based on past sales can sharpen your ordering.
- Not training your team means inconsistent processes and poor data quality, so invest time in documenting procedures and showing everyone how to handle stock the same way.

FAQs on stock management
Here are some frequently asked questions about stock management.
What's the difference between stock management and inventory management?
The terms are often used interchangeably. In some contexts, "stock" refers specifically to finished goods ready for sale, while "inventory" covers everything, including raw materials and work in progress.
How often should you count your stock?
It depends on your business size and product volume. Many small businesses find that monthly full counts, combined with weekly spot-checks of high-value or fast-moving items, strike the right balance between accuracy and effort.
Can you manage stock effectively without software?
You can use spreadsheets when you have a small product range, but manual methods become unreliable as you grow. Software reduces errors, saves time and gives you real-time visibility that spreadsheets can't match.
What is stock turnover and why does it matter?
Stock turnover measures how many times you sell and replace your inventory over a given period. A higher turnover rate generally means you're selling efficiently, while a low rate may signal overstocking or weak demand.
How do you handle stock for an online and physical store?
Use a centralised stock management system that syncs inventory across all your sales channels. This prevents overselling and makes sure a sale in your online store immediately updates the stock count for your physical location.
