TL;DR: No single inventory app is best for every business, so start by matching the app category to how you sell, whether that's retail POS, multichannel e-commerce, wholesale, manufacturing, food and drink, or field equipment. Then check the features and plan limits you'll need within a year, test one complete flow from receiving to returns before you commit, and consider a custom-built app if no packaged option fits your process.
You want to stop losing track of stock and choose an inventory app your team will use. The warning signs are familiar. A bestseller runs out without notice, someone orders the same item twice, or the shelf counts don't match the spreadsheet.
These problems get worse as you sell in more places. A storefront, an online shop, and a marketplace can all draw from the same shelves. When they do, stock changes faster than anyone can update a sheet by hand.
This guide matches seven business types to the inventory apps built for them. You'll also learn which features to look for, where free plans fall short, how to test an app in four steps, and when a custom inventory app is the better fit.
Which inventory app fits your business type?
The best app for inventory management is the one built for the way your business sells. A single store usually does well with a POS (point of sale) app like Square. A multichannel seller needs stock sync from a tool like Zoho Inventory, and a manufacturer needs material tracking from an app like Katana.
Find your row in the table, then read the section for your category. Features and free plans change often, so check each vendor's site for current details. These options were last checked in October 2026.
| Business type | Example apps | Best for | Look elsewhere if |
|---|---|---|---|
| Retail POS | Square, Lightspeed, Loyverse | Single storefronts | You need advanced purchasing or warehouse tools beyond what your POS supports |
| E-commerce and multichannel | Zoho Inventory, Shopify | Selling on several channels | You only sell in person |
| Wholesale and multi-location | inFlow, SalesBinder, Odoo | Suppliers and stock transfers | You have one location and few products |
| Manufacturing | Katana, InvenTree | Materials and finished goods | You only resell finished products |
| Bars and restaurants | Backbar | Counts by volume or weight | You sell packaged retail goods |
| Mobile, small teams, and field work | Sortly | Tools, supplies, and equipment | Your main job is selling stock |
| Custom-built | Built around your process | Workflows no package supports | A packaged app already fits |
Retail POS inventory apps
A POS system is the software that rings up sales in a store. When your inventory links to it, each sale lowers the stock count automatically.
Square and Lightspeed are common choices for storefronts, and Loyverse is another option to evaluate for mobile POS. Some POS tools get harder to manage once purchasing, supplier management, or warehouse workflows become complex. Check each vendor, though. Square, for example, supports multi-location stock tracking and transfers.
E-commerce and multichannel inventory apps
Overselling happens when the same item sells on two channels before the stock count updates. Multichannel apps prevent it by syncing stock across sales channels like Shopify, Amazon, and eBay.
Zoho Inventory is a common multichannel pick, and Shopify's built-in inventory may also fit Shopify-first sellers. Many of these apps also handle kitting, which is selling bundles made from several SKUs. A SKU (stock keeping unit) is the unique code you give each product variant, like a blue medium T-shirt.
Wholesale and multi-location inventory apps
Wholesalers need purchase orders, supplier records, and stock transfers between locations. They also need user roles, which control who on the team can change counts.
inFlow covers many of these needs, including purchase orders, approvals, user access rights, B2B portals, and multi-location inventory. SalesBinder and Odoo are other options to evaluate. For many inventory apps, adding locations is a paid-plan trigger, though plan rules vary. Katana's Free plan, for example, lists unlimited inventory locations but limits SKUs.
Manufacturing inventory apps
A bill of materials (BOM) is the list of parts and raw materials that go into a finished product. Manufacturing apps use it to track materials and finished goods together. When you build one table, the app subtracts its legs and screws from stock.
Katana is built for manufacturers. InvenTree is open source, so you can review and change its code. It suits teams that are comfortable hosting and setting up software themselves, so check its documentation for current setup requirements.
Bar and restaurant inventory apps
Food and drink are counted by volume or weight, and many items expire. Staff need to count storage areas quickly on a phone during a shift, and recipe costing matters as much as the count. If you need expiration-date tracking, check that the app you choose supports it.
Backbar is built for bars and beverage businesses. It includes drink costing and recipe features that general retail tools may not prioritize.
Mobile inventory apps for small teams and field work
Some teams track tools and supplies spread across job sites, service vans, and stockrooms. They often need photo records, QR or barcode labels, job tracking for what goes out and comes back, and offline mobile access where the signal is weak.
Sortly is a common choice in this category. It fits teams that track things they use more than things they sell.
Custom-built inventory apps
A custom inventory app makes sense when your process doesn't fit any category above. These signals point that way:
- Unusual item structures: Your products don't fit a standard SKU. A flooring company, for example, tracks rolls by width and length and cuts one roll into several jobs.
- Approval steps: Your process includes a step packaged apps skip. For example, a manager might need to approve any stock adjustment over a set value before it posts.
- Customer-facing features: You want suppliers or clients to log in. A supplier portal, for example, would let vendors confirm purchase orders and ship dates themselves. Businesses in industries like construction management often need this kind of multi-party coordination alongside material and equipment tracking.
If these sound familiar, the Bubble section below covers what building a custom app looks like.
What features should an inventory app have?
An inventory app should make the tasks your team already does each week faster. These are the features that matter most for most businesses:
- Real-time stock levels: Counts update the moment an item sells or arrives. This matters most when several people or channels draw from the same stock.
- Low-stock alerts and reorder points: A reorder point is the stock level that should trigger a new order. When stock reaches that level, an alert warns you before a stockout, which is when an item runs out completely.
- Barcode and QR code scanning: You scan items with a phone camera or a scanner. Scanning speeds up counts and picking, which is gathering items for an order, and it cuts typing errors.
- Purchase orders and supplier records: A purchase order is the formal request you send a supplier. When you keep orders in the app, you can see what's already on the way and avoid ordering it twice.
- Multi-location tracking: You follow stock as it moves between a warehouse, a store, and a van. Without it, transfers turn into guesswork.
- Integrations: The app connects to your POS, online store, accounting software like QuickBooks, and shipping tools. Each connection removes a round of retyping.
- Role-based access and audit trails: You control who can change counts, and you can see a record of every change. That record makes it much faster to find out why counts don't match.
- Reports: Reports show your fast movers and your dead stock, which is stock that hasn't sold in a long time. You can use them to reorder bestsellers and clear out slow items.
Cycle counts are also worth having. A cycle count is when you count one section of inventory on a regular schedule. You avoid shutting down to count everything at once.
Tip: Write down your team's weekly inventory tasks before you compare apps. Skip any feature you can't connect to one of those tasks.
Is free inventory management software enough?
Free inventory software costs nothing, but it caps what you can do. Free plans vary widely. Some cap users, locations, orders, items, or SKUs, and others limit report history or integrations. Purchase orders, label printing, and API access may be free, paid, add-ons, or unavailable depending on the vendor. Zoho Inventory's Free plan, for example, includes limited purchase orders and API calls, while Sortly reserves API and webhooks for its Enterprise plan. An API is the way one app connects to another.
| Capability | Spreadsheets | Free inventory apps | Paid inventory apps |
|---|---|---|---|
| Real-time updates | Manual entry only | Within plan limits on locations, items, or orders | Across all locations |
| Multiple users | Possible, but permissions get hard to manage | A few seats | With user roles |
| Sales channel sync | Not available | Usually limited or none | Most major channels |
| Low-stock alerts | Not available | Basic alerts | With reorder points |
| Audit trail | General version history, no inventory-specific trail | Often limited | Full change history |
| Mobile app and scanning | Mobile editing, but not built for scanning | Often included | Included, with offline options on some |
A spreadsheet can still work when one person tracks a short item list that rarely changes, but inFlow's 2026 survey found 84.8% of operators still use spreadsheets for inventory. It's time to switch when you notice these signs:
- Counts stop matching: The shelf says six and the sheet says nine. Each mismatch costs time to track down — one business found $217,000 in annual savings after improving its inventory accuracy from 87% to 99%.
- More than one person edits: Two people update the same sheet, and one overwrites the other. You lose track of which number is right.
- You sell on more than one channel: A store and a website pull from the same stock. Manual updates can't keep up, and orders get oversold.
Staying on a free plan too long has costs too. Shared logins hide who changed what, and without a change history, a missing pallet is hard to trace.
How do you choose an inventory app?
These four steps take you from a long list of apps to one decision. Use the features list above as your checklist.
Start with your business type
Use the category table to narrow your list to two or three apps. If you compare every inventory app on the market, you'll spend weeks on research.
Check the plan limits you'll hit this year
Compare users, locations, orders, and integrations against where you expect your business to be in a year. A plan that fits today may force a switch during your busiest season.
Test one complete inventory flow
During a free trial, take one actual item through the whole process. Receive it, move it, sell or ship it, and then process a return. Use the same screens your team will use, including the mobile app.
Confirm integrations and support
Check that the app connects to the POS, online store, and accounting tools you already use. Also find out how vendor support helps when counts don't match.
What's the best app builder for a custom inventory app?
Bubble is the fully visual app builder for creating custom web and native mobile inventory apps with AI, without giving up control of how the app works. You can understand every part of your app and change it yourself.
If your needs are simple, a spreadsheet-based builder like Glide can handle a basic internal list. If your process already fits one of the categories above, a packaged inventory app is often the faster choice.
To build on Bubble, describe your inventory app to the Bubble AI Agent. It starts with a planning session, asks clarifying questions, and drafts a blueprint. For an inventory app, you can give it details like items, locations, suppliers, and purchase orders.
After you review and approve the plan, the Agent generates the pages, database, workflows, and privacy rules, all of which stay visible and editable in the Bubble editor.
- Understand: Your low-stock alerts and reorder logic are visual workflows that read as plain-language steps. When a count looks wrong, you can trace the cause and change the logic yourself.
- Refine: Ask the Agent to add a feature, or edit any layer yourself in the same visual editor. You can use the API Connector to connect commerce, accounting, or supplier tools that expose compatible APIs, after confirming each service's API requirements. You can also roll back changes with version control, and on paid plans, the security dashboard flags vulnerabilities before you deploy.
- Scale: With Bubble for native mobile apps, you build web, iOS, and Android apps from one editor, and they share one backend. Native mobile apps can use device capabilities like the camera and photo library, so confirm that your barcode scanning and offline needs are covered before you scope the build. With native mobile app generation (beta), the Agent can create the mobile app from a prompt. Bubble is SOC 2 Type II compliant.
RT Bayles, CEO of a residential flooring company, built the custom ERP that runs his business despite having no software development experience. An ERP is a single system for a company's core operations.
"Being able to build a tool where my team can do everything in one app and do it the way we want it done — I don't have a number to put on this, but it's honestly priceless," says RT. Read the Floor Authority story. Brian Henderson built Wash-Dry-Fold POS, a point-of-sale and operations system for laundromats, and he still grows it on the same app.
Getting started is free, and generating an app with the Agent doesn't use AI credits. Building and iterating with the Agent uses AI credits, while editing in the visual editor doesn't.
Find the right inventory app for your business
The right inventory app matches your business type, fits the plan limits you'll reach next, and passes one complete test flow. Shortlist two or three apps from the category table and start your trials.
If none of them fits the way your business works, you can build a custom inventory app on Bubble and keep every page, workflow, and privacy rule visible and editable. Start building for free by describing your inventory app to the Agent.
Frequently asked questions
What's the difference between an inventory app and inventory management software?
An inventory app usually means a mobile-first tool for counting and tracking stock. Inventory management software usually adds purchasing, multiple locations, and reporting.
Do small businesses need a barcode scanner for inventory tracking?
Many small businesses start by scanning with a phone camera in their inventory app. A dedicated scanner is worth buying once counting or picking speed starts to slow your team down.
Is Zoho Inventory free for small businesses?
Zoho Inventory offers a Free plan. On its US pricing page, the plan includes 50 orders per month, one user, and one location, along with other limits. Check Zoho's pricing page for the current limits in your region.
How do you move inventory from a spreadsheet into an inventory app?
Clean up your item list and SKUs, import the file, and run the spreadsheet and the new app side by side for a short time. Once the counts match, lock the spreadsheet so no one keeps editing it.
