Retail inventory · September 20, 2026
Best inventory software for retail (2026)
The job is one available-to-sell number at the counter. Ecommerce-only inventory is a sibling page.
By Gregory GreensteinUpdated September 20, 2026Affiliate disclosure
Retail inventory fails when the shelf, the iPad, and the website each have their own count. The job is: sell a unit, decrement one number, reorder before you oversell. This page is store-first. Shopify-warehouse brands should read ecommerce inventory. AI planogram tools stay on Aiacent.
Square is the default single-location counter. Shopify POS wins when the catalog already lives on Shopify. Lightspeed is the published retail OS. Zoho Inventory is the cost-sensitive multi-channel add-on.
Prices as of September 20, 2026. Processing is the real bill. This is not inventory-valuation advice.

01
Square
Single-location US shops that want stock on the same iPad that takes the card
Public pricing: Square Free $0/month software; in-person 2.6% + 15¢. Plus $49/month per location (2.5% + 15¢). Premium $149/month per location (2.4% + 15¢). Inventory tracking sits on the POS plans. Hardware extra.

Skip if
You already live in Shopify for ecommerce and need the same catalog at the counter — use Shopify POS. Or you manufacture. That is Katana.
Why it ranks
- The register and the stock count share a login — the shop job.
- Free is enough for a single counter until variants and purchase orders appear.
- Ranks first on the POS list for the same reason.
- You can be live this week.
Watch-outs
- Free inventory is thin for multi-location and serious POs.
- Processing is the tax you already pay. Model Plus if the rate matters.
- Not an MRP.
- A restaurant should look at Toast, not this page.
02
Shopify POS
Retailers whose website is already the system of record
Public pricing: Paid Shopify plans start at $39/month. Inventory is included on the plan. POS Pro is +$89 per location if the floor is real. Confirm shopify.com/pos/pricing.
Shopify POS pricing, reviewed September 20, 2026.
Skip if
You are a counter-only shop with no Shopify store. Do not buy a $39 plan just to count soap.
Why it ranks
- One catalog online and in the shop is the entire reason to stay native.
- POS Lite rides the same stock if you pop up.
- You already pay for commerce. Do not add Cin7 for a single storeroom.
- Ranks first on ecommerce inventory for the same catalog reason.
Watch-outs
- Multi-location and wholesale complexity outgrow native fast.
- App Store inventory apps stack fees and sync bugs.
- Third-party payment extra fees if you leave Shopify Payments.
- Not a manufacturing MRP.
03
Lightspeed Retail
Independent retailers who need a dedicated retail OS, not a card dongle
Public pricing: Retail (X-Series) Basic $89/month; Core $149; Plus $289. Inventory management is on the plans. Extra registers and Lightspeed Payments (card-present marketed at 1.5% on the pricing page) change the bill. Confirm lightspeedhq.com/pos/retail/pricing.
Lightspeed official retail POS pricing, reviewed September 20, 2026.
Skip if
You are a one-register gift shop. Square Free is enough. Lightspeed is a retail platform with a published $89 floor.
Why it ranks
- Products, variants, and purchase orders are first-class — the specialty-retail job.
- Published three-rung card. You can defend Core in an owner meeting.
- Ecommerce and accounting integrations exist when the site is not Shopify.
- A known floor system when you hire from another Lightspeed shop.
Watch-outs
- Onboarding and extra registers stack. Model the all-in, not $89.
- Payments rate is its own conversation. Read the current card-present page.
- Overkill next to Square if you have one SKU wall.
- Multi-location quotes appear. Get them in writing.
04
Zoho Inventory
Shops that need multi-channel stock without Cin7 money and already tolerate Zoho
Public pricing: Zoho Inventory publishes Free / Standard / Professional / Premium / Elite rungs on zoho.com/inventory. Confirm the live US card — packaging moves. Treat the official calculator as the price.
Zoho Inventory official pricing (zoho.com/inventory/), reviewed September 20, 2026.
Skip if
The register is Square or Shopify and the stock room matches. A second inventory system is how you double-count.
Why it ranks
- A cost-sensitive path when Amazon, a site, and a counter disagree.
- Sits next to other Zoho apps if you already live there.
- Ranks on the ecommerce inventory list for the same reason.
- Useful when Lightspeed is more POS than you will operate.
Watch-outs
- Two systems of record (POS + Zoho) need a sync rule.
- Not a replacement for a CPA at year-end.
- Cin7 is the heavier multi-warehouse buy if you outgrow this.
- Implementation is mapping, not a toggle.
How we picked
The job is US retail available-to-sell for shops under ~50. We scored POS adjacency, published prices, and whether the product is the register or a second system. Cin7 and Katana stay on the ecommerce page. Toast is a restaurant platform.
