A September 21, 2026 Fortune review looks at accounting software that keeps bookkeeping, inventory, and orders in one place. When a sale, return, or restock posts, the stronger tools update the stock count, record cost of goods sold, and log revenue without a second manual entry. Sellers then see profit as it happens, instead of waiting to type the same numbers into a separate system. That live count also lowers the chance of selling units you do not have, which matters if you sell from a store, a website, and a marketplace such as Amazon at the same time.
Fortune treats QuickBooks Online, Xero, and Zoho Books as the main cloud options for small and midsize businesses. Inventory is not on every plan: QuickBooks gates it to Plus and Advanced, Xero points higher-volume sellers to an Inventory Plus add-on, and Zoho offers Zoho Inventory when tracking gets more complicated. The review's checklist is real-time stock tracking, purchase order automation, multi-channel sales sync, and valuation methods such as FIFO and average cost. Multiple warehouses or very high order volume is where Fortune says an ERP such as NetSuite or Intuit Enterprise Suite fits better than a standard accounting plan. Free tools can cover basic stock counts, but they usually cap how many items you can track and how much of the work they automate.

QuickBooks, Xero, and Zoho
QuickBooks Online puts inventory and order tools on Plus and higher, regularly $140 per month for Plus. Those plans include real-time stock counts, alerts when supply runs low, and purchase orders that can turn into bills when goods arrive. A sales order can set units aside for a customer before you invoice, so the books do not treat the order as a sale yet and you are less likely to sell that stock to someone else. Fortune points sellers who need several warehouses or barcode scanning to QuickBooks Desktop Enterprise rather than a standard Online plan.
Xero updates stock on its own, so you are not retyping counts to see what you have. Item prices and descriptions can fill an invoice, and stock moves as soon as you create that invoice or a purchase order. Shops with many products across more than one sales channel are directed to Inventory Plus, which costs $39 per month and requires the Growing plan or above. Fortune says the add-on handles more than double the order volume of Xero's standard inventory feature and includes guided onboarding.
Zoho Books stores SKUs, product costs, images, taxes, and preferred vendors so invoices can fill in automatically. It shows what you have on hand and which units are already promised to buyers. The Zoho Inventory add-on is the step up for more complicated tracking: bundles of items sold together, packages that ship as one shipment, and links to shipping carriers.
How Fortune describes inventory and order tools on three small-business platforms
| Software | Real-time stock tracking | Purchase orders | Multi-channel sales | Inventory valuation |
|---|---|---|---|---|
| QuickBooks Online | Included on Plus and Advanced, with low-stock alerts | Purchase orders can become bills; sales orders can reserve stock before invoicing | Multi-warehouse tracking and barcode scanning are on Desktop Enterprise | Confirm FIFO or average cost on your plan |
| Xero | Stock updates when an invoice or purchase order is created | Creating a purchase order updates stock levels | Inventory Plus add-on ($39/month) on Growing and above, for more orders across sales channels | Confirm FIFO or average cost on your plan |
| Zoho Books | Shows on-hand units and stock already promised to buyers | Not covered in the Fortune review | Zoho Inventory add-on adds bundles, ship-together packages, and carrier links | Confirm FIFO or average cost on your plan |
Fortune names FIFO and average cost as methods worth comparing, but it does not say which method each platform uses. If you buy the same product at different costs, confirm that on the plan you would actually pay for. The table above sticks to what the review states.
Inventory Valuation
Valuation is how the software records cost when you sell an item, and it changes both gross profit and taxable income. Fortune's example: buy a unit for $10 and sell it for $20, and gross profit is $10. Buy the same item later for $15 and sell it for $20, and gross profit is $5. Software that can tell those units apart, even when they are the same product, is what makes FIFO or average cost useful at tax time.
Most marketplace sellers do not need warehouse-scale systems to get that benefit. Forbes Advisor's comparison of SAP vs. Oracle shows how large ERP platforms emphasize multi-location inventory and financial consolidation well beyond a typical Etsy or Shopify shop. Forbes Advisor's guide to restaurant inventory management software makes a related point from another industry: stock that drops when a sale posts is now a baseline expectation, not a specialty feature. The same link between a sale and the books is what cuts retyping errors for ecommerce sellers.
What to Check First
Before you move your books, match a platform against the features Fortune treats as the decision list. Stock should update after a sale, a return, or a restock. If you fulfill from more than one place, confirm multi-location tracking, which Fortune says is more common in ERP systems than in standard small-business accounting software. Purchase orders should be creatable in the product, ideally with low-stock alerts and a reorder draft, so you are not checking supplier status by hand. Orders from each storefront should land in one live inventory count. Without that, manual entry is how shops sell more units than they hold.
Also check the valuation method, the monthly cost of the tier or add-on that actually includes inventory, and whether the software connects to the payment processors and sales channels you already use. A plan you still have to update by hand does not remove the overselling risk. Fortune's sizing rule is straightforward: a cloud accounting plan is enough for many small and midsize sellers, and a heavier system is for high order volume or several warehouses. The more complete tools also take longer to learn.
Final Thought: If you sell physical goods, accounting software that updates stock, purchase orders, and channel orders together saves retyping and makes overselling less likely. QuickBooks, Xero, and Zoho can cover a typical small shop once you are on the plan or add-on that includes inventory. Confirm valuation method and channel coverage before you commit, and look at an ERP only when one location and a standard order volume are no longer enough.
