Inventory software for a small business in 2026: decide who counts the stock first

Most small businesses do not lose money on inventory because they picked the wrong app. They lose it because nobody owns the number. Stock that was already paid for sits in a storeroom while the shop reorders it again, a best-seller runs out during the week it would have sold best, and working out the real margin on one product takes three spreadsheets and a phone call.

So decide who is going to count before you compare features. That single answer removes most of the shortlist, and it explains why two businesses with the same turnover end up on completely different software.

Who is going to run it?

The owner, on a phone, between other jobs. Photo-first tools are built for this: photograph an item, stick a QR label on it, scan with the phone camera and the quantity moves. Setup is an afternoon rather than a project. The trade-off is depth - purchasing, manufacturing and heavy accounting links are thin.

A warehouse or wholesale team, scanning all day. Here barcode-first workflows and a desktop application alongside the cloud are worth paying for, because receiving and picking happen at a bench, not in a browser tab.

Someone already juggling several sales channels. Once stock has to stay correct across your own store, a marketplace and wholesale orders, you are no longer buying an inventory tool. You are buying an order management platform, and the price bracket moves with it.

The four jobs, whichever tool you choose

Strip the marketing pages away and every product on the shortlist does four things: it counts what you hold, it moves the count when you buy or sell, it tells you when to reorder, and it reports what the stock is worth. What separates them is how much setup each job takes and how many places the tool is able to count.

What the shortlist actually costs

Figures below are vendor list prices read in September 2026. This category reprices often and some vendors render their tiers dynamically, so confirm on the official pricing page before you commit.

• Sortly - a Free tier for a very small item count, then Advanced at $49/month monthly or $24/month billed yearly ($288/year, 500 unique items), Ultra at $149/month or $74/month yearly ($888/year), and Premium at $299/month or $149/month yearly ($1,788/year).
• Zoho Inventory - priced per organisation rather than per user: Standard from $29 per organisation per month billed annually, with extra users around $7.50 and extra locations around $10. Usually the cheapest route for a team of three or four.

• Odoo - the free and open-source route, provided you have someone technical enough to run it on a server you rent.

Match the tool to the situation you are in now

One storeroom, one channel. A cheap photo-first tool, or even a well-built spreadsheet, is genuinely enough. Do not pay for multi-location logic you will never use.

A shop plus a storeroom. You need stock per location rather than one global figure, plus low-stock alerts that fire before a best-seller reaches zero.

Several channels. Stock has to come down automatically the moment an order lands anywhere, or you oversell and then apologise to the customer.

Six questions to settle before you pay

1. Can I export everything I put in, in a format I can read somewhere else?
2. Does the price cover the people who will actually log in?
3. Does the tool connect to the accounting software I already use?
4. Does barcode scanning work on the phone I already own, or do I need to buy a scanner?
5. What happens to my data if I stop paying, and for how long is it kept?
6. Who counts stock on the last day of the month, and does the tool make that job shorter?

When a spreadsheet is still the right answer

If one person, one location and a few hundred lines describe your business, a tidy spreadsheet is cheaper and faster than any subscription. The moment there is a second place to count, or a second person touching the same file, the spreadsheet starts costing more than software would - not in licence fees, but in the hours spent reconciling versions that no longer agree with each other.
