To choose inventory management software, settle five decisions first: how many orders and SKUs you need to cover, which sales channels must stay in sync, whether you need lot, serial, or manufacturing tools, which accounting system the counts and costs must reach, and what the plan will cost once you pass its caps. Most tools track stock well enough. The differences show up in channel connectors, order limits, and how much setup the data needs.
Define the problem you are actually solving
Inventory software gets bought for very different reasons, and the reason should shape the shortlist. Write down the one or two problems that cost you money today before you open a single demo.
- Overselling. You sell the same units on Shopify, Amazon, and a wholesale account, and counts drift until a customer buys something you no longer have.
- Stockouts and dead stock. You reorder by gut feel, so best sellers run out while slow movers tie up cash.
- Purchasing chaos. Purchase orders live in email threads, and nobody knows what is on the water or when it lands.
- Cost accuracy. Your accountant cannot get a reliable cost of goods sold because landed costs, freight, and duties never reach the books.
- Production. You make or assemble products and need raw materials to drop when finished goods are built.
A single Shopify store with one stockroom may not need a dedicated system yet. Shopify tracks basic counts for one store well. The case for new software gets strong the moment you add a second channel, a second location, wholesale orders, bundles, or regular purchase orders.
Size the plan to your orders, SKUs, and locations
Nearly every inventory tool prices by some mix of orders, users, locations, and connected channels. Pull your real numbers before you compare tiers:
- Count orders over the last 12 months and find your busiest month. Q4 peaks are what break order caps.
- Count active SKUs, including variants. A shirt in five sizes and four colors is 20 SKUs.
- List every stock location: your warehouse, a 3PL, Amazon FBA, a retail store, and any consignment stock.
- Count the people who need logins, including warehouse staff who only scan.
Then read the caps closely. Zoho Inventory’s free plan covers 50 orders a month, and its paid plans start at $29 a month billed yearly with a 500-order monthly cap on the entry tier. Cin7 Standard costs $349 a month and includes five users and 6,000 sales orders a year, with Pro at $599 and Advanced at $1,199. Cin7 also limits how many ecommerce and app integrations each plan includes, with more available for purchase. Pick a tier you will not outgrow inside six months, because a forced mid-year upgrade often doubles the bill.
Confirm every sales channel connects natively
Channel sync is the main job for most ecommerce sellers. List every place you sell and check that the tool pushes stock levels and pulls orders from each one directly, without a spreadsheet or a third-party connector in the middle.
Channels and systems to check
- Storefronts. Shopify, BigCommerce, WooCommerce, and Squarespace each have their own quirks with variants and bundles.
- Marketplaces. Amazon (including FBA stock), Walmart Marketplace, eBay, Etsy, and TikTok Shop. Ask how the tool handles stock held in FBA versus your own warehouse.
- Wholesale. A B2B ordering portal, price lists by customer, and EDI if you sell to big-box retailers. EDI usually runs through a partner, so ask which ones the vendor supports.
- Shipping. Whether you print labels inside the tool or pass orders to ShipStation or a 3PL.
- Point of sale. If you run a store or pop-ups, confirm in-person sales draw from the same count.
Ask how often stock syncs. Near real-time sync matters during a flash sale. A 15-minute delay is fine for a store that sells a few dozen orders a day. Linnworks is built around wide marketplace coverage and order routing rules, which is why it suits high-volume marketplace sellers more than a small Shopify brand.
Decide which tracking and production features you need
This is where tools split into camps, and where buyers overpay most often. Match features to the products you actually sell.
- Lot and expiry tracking. Food, supplements, cosmetics, and anything that could face a recall need batch numbers and expiration dates on every unit sold. FDA rules for food traceability raise the stakes for some products.
- Serial numbers. Electronics and high-value goods often need unit-level tracking for warranties and returns.
- Bundles and kits. If you sell gift sets or multipacks, the system must deduct each component when a bundle sells.
- Bills of materials. Brands that make products need raw material tracking, production orders, and costing. Katana is built for this, with a free plan covering up to 30 SKUs and all features.
- Warehouse tools. Barcode scanning, bin locations, pick lists, and cycle counts matter once you have more than a few shelves.
Costing method belongs on this list too. Ask whether the tool supports FIFO or weighted average costing, whether you can add freight and duties to landed cost, and whether those costs flow to your accounting system as cost of goods sold. Getting this wrong means your margins are a guess.
Check the accounting sync, not just the logo
Most inventory tools list QuickBooks Online and Xero as integrations. What matters is what moves between them. A good sync posts invoices, bills, and cost of goods sold so your inventory asset account matches your stock report. A weak one only pushes sales totals and leaves your bookkeeper to fix the rest each month.
- Does it post cost of goods sold per sale, or only revenue?
- Do purchase orders become bills in the accounting system?
- Which system owns the item list and prices, so they do not fight each other?
- If you use Zoho Books or another suite product, is there a native link? Zoho Inventory pairs naturally with Zoho Books, which suits small teams already on Zoho.
Price the total cost, not the entry tier
Published entry prices rarely match the real bill. Inventory software costs range from free to well over $1,000 a month, and the gap between tiers is steep.
Realistic price ranges in 2026
- Free to about $100 a month. Small sellers on Zoho Inventory, Katana’s free plan, or entry tiers with tight order caps.
- About $100 to $700 a month. Growing brands and wholesalers. inFlow runs from $99 a month billed yearly up to $699.
- $349 to $1,200 or more a month. Multichannel brands on Cin7 or Ordoro’s inventory tier, before add-ons.
- Custom quotes. Linnworks, Cin7 Omni, and Katana’s paid Advantage plan quote by sales. Linnworks also charges a one-time onboarding fee.
Add the costs that sit outside the plan: extra users, extra integrations, add-on modules such as a B2B portal or forecasting, premium support, and paid onboarding. Then model the next 12 months at your expected growth, not today’s volume. For a side-by-side view of current prices and caps, see our ranked list of the best inventory management software.
Plan the migration and run a real trial
The import is where most rollouts stall. Clean your data before it moves, or you will carry every old error into the new system.
- Standardize SKUs and remove duplicates. Make sure every variant has a unique SKU that matches each channel listing.
- Fix units of measure. Buying by the case and selling by the unit needs a clear conversion.
- Do a full stock count right before go-live so opening balances are real.
- Connect one channel first, confirm counts match for a week, then add the rest.
- Run old and new systems side by side through at least one purchase order cycle.
During the trial, process real orders, not demo data. Receive a purchase order, sell a bundle, return an item, and move stock between locations. Then check that the accounting entries look right. Ask what onboarding is included, since options range from group sessions to one-to-one and partner-led setup, and setup on a platform like Cin7 takes real time and data cleanup.

Frequently asked questions
When should you move from spreadsheets to inventory software?
Move when a mistake costs more than the software. That usually happens when you add a second sales channel, a second stock location, or regular purchase orders. Overselling on a marketplace can hurt your seller rating, and a missed reorder on a best seller loses sales for weeks, so even a free or $29 plan pays for itself quickly.
Can you run inventory software alongside a 3PL?
Yes, and many sellers do. The inventory system holds the master count and pushes orders to the 3PL, which ships them and reports stock back. Ask both vendors whether a direct integration exists, how often counts reconcile, and which system wins when numbers disagree. Without a clean connection, your team ends up updating stock by hand.
Do you need lot or batch tracking?
You need it if you sell food, supplements, cosmetics, or anything with an expiration date or recall risk. Lot tracking lets you see which customers bought a specific batch, which matters if a supplier issues a recall. Check which plan tier includes it, because some tools reserve batch and serial tracking for their mid or upper plans.
How long does it take to set up inventory software?
Simple setups with one store and clean SKUs can go live in a few days. Multichannel brands with wholesale, several warehouses, and accounting sync should plan for several weeks. Most of that time goes to cleaning SKU data, counting stock, and testing each channel connection, not to learning the software itself.
Should you choose an inventory tool that also prints shipping labels?
Choose one if you want fewer systems and ship moderate volume yourself. Ordoro combines shipping, inventory, and dropshipping in one tool. If you already rely on a dedicated shipping platform or a 3PL, a pure inventory system that passes orders to them is usually the cleaner setup.
