Stock control with Xero
Track items and see what's selling with Xero's stock control software
If you sell physical products, keeping the right amount of each item on hand is one of the trickiest parts of running your business. Getting it right starts with understanding what stock management actually involves.
Stock management is the process of managing the goods your business plans to sell, including acquiring, storing, organising and tracking those items. It also means keeping records of how your stock changes over time so you can meet customer demand without over-ordering.
You might see stock management called stock control, inventory management or inventory control. These terms all describe the same job: knowing what you have, where it is, and when to order more. To go deeper on the wider topic, you can read Xero's guide to inventory.
Why stock management matters
Stock is often one of the biggest investments a small business makes, so how you manage it affects your bottom line. Getting the balance right keeps money available and customers happy.
Holding too much stock ties up cash you could use elsewhere, and it adds storage and insurance costs. Stock can also lose value or spoil before it sells, so overstocking carries real risk.
Holding too little brings its own problems. If you run out of a popular item, you can miss sales, disappoint customers and send them to a competitor. Careful stock management helps you protect cash flow, control costs and keep customers satisfied.
Types of stock
Not all stock plays the same role in your business. Sorting your items into clear categories makes them easier to track and value.
- Raw materials and components: the inputs you buy to make a finished product
- Work in progress: partly finished goods that are still being made
- Finished goods: completed products that are ready to sell
- Consumables: supplies you use in daily operations, such as packaging or cleaning products
Common stock management methods
Businesses use a range of proven methods to decide how much to hold and when to reorder. The right mix depends on what you sell and how quickly it moves.
- Just in time (JIT): order stock so it arrives just as you need it, to keep holding costs low
- First in first out (FIFO): sell your oldest stock first, which suits perishable or dated items
- Economic order quantity (EOQ): calculate the order size that keeps ordering and holding costs as low as possible
- ABC analysis: rank items by value so you focus attention on your most important stock
- Safety stock: hold a small buffer of extra stock to cover unexpected demand or supply delays
- Reorder points: set a stock level that triggers a new order before you run out
How to manage stock: key steps
Managing stock well comes down to a repeatable routine you can follow every week or month. These steps give you a simple process to manage inventory from order to reorder.
- Forecast demand by looking at past sales, seasonal trends and any planned promotions.
- Order stock in quantities that match your forecast and your budget.
- Receive and store items safely, checking them against your order as they arrive.
- Track stock levels as you sell, ideally in real time, so your records stay accurate. A regular stocktake, or physical count, helps you confirm what you actually have.
- Review performance to spot slow movers, fast sellers and any losses.
- Reorder when stock hits your reorder point so you avoid running out.
Stock management systems and software
You can track stock in several ways, and the best choice depends on how many products you sell and how fast they turn over. As you grow, moving from manual methods to software saves time and reduces errors.
- Manual tracking: counting stock by hand and noting it on paper, which suits very small ranges
- Spreadsheets: recording stock in a document you update yourself, using a free inventory template to get started
- Dedicated software: an inventory management system that updates levels automatically and links to your sales and accounts
Software also supports accurate inventory accounting, so the value of your stock flows straight into your books.

FAQs on stock management
Here are answers to some frequently asked questions about stock management to help you put these ideas into practice.
What's the difference between stock management and inventory management?
There's no real difference, as the two terms describe the same process of tracking and controlling the goods you sell. Stock management is more common in New Zealand and the UK, while inventory management is used more in the United States.
What is the FIFO method?
FIFO stands for first in first out, which means you sell your oldest stock before your newest. It's a good fit for perishable or dated products, as it reduces the chance of stock spoiling before it sells.
What's the difference between periodic and perpetual inventory systems?
A periodic system updates your stock records at set times through a physical count, while a perpetual system updates them automatically with every sale. Perpetual systems give you a more accurate, real-time view but usually need software to run.
Can I manage stock with a spreadsheet?
Yes, a spreadsheet works well for a small number of products and a simple range. As your stock grows, dedicated software saves time and cuts down on manual errors.
