Top Shopify Purchase Order Apps in 2026

A Shopify purchase order app connects the parts of restocking that Shopify's built-in tools don't fully cover: demand forecasting, supplier management, barcode-based receiving, and multi-channel purchase order (PO) syncing. Shopify replaced its old Stocky app with native inventory and PO tools inside the admin, but those tools are still limited to basic order creation,  they don't forecast demand, manage supplier records, or handle partial receiving well. That gap is what third-party purchase order apps for Shopify are built to close.

This guide compares the leading Shopify apps for purchase orders in 2026, breaks down what each one does best, and lays out the features worth prioritizing based on how your store actually operates.

Key Takeaways

• Shopify's native PO tools cover basic order creation but lack forecasting, supplier history, and barcode receiving, this is why most growing stores add a dedicated app.

• Pricing for Shopify purchase order apps ranges from free (ChannelBay, Stockroom) to $199/month for enterprise-grade forecasting (Prediko, Assisty).

• The right app depends on your priority: automation (Auto Purchase Order), multi-channel selling (ChannelBay), AI-driven forecasting (Assisty, Prediko), or warehouse/barcode operations (EasyScan, StockSavvy).

• Look for five core capabilities before choosing: forecasting, PO creation, PO management and tracking, partial receiving, and supplier management.

When Do You Need a Purchase Order App for Shopify?

You need a dedicated purchase order app once manual reordering starts costing you sales or time, typically when you're managing more than a handful of SKUs, ordering from multiple suppliers, selling on more than one channel, or receiving stock in partial shipments that Shopify's native tools can't reconcile cleanly. A well-designed workflow starts with low-stock alerts and reorder suggestions, predicts the right quantity to purchase, and lets you create and track POs with product and supplier details attached, all without leaving Shopify.

ChannelBay - Purchase Order

Best for
Sellers running purchase orders across multiple sales channels, retail, and Shopify POS.

Core strength
ChannelBay is a comprehensive purchase order app built for Shopify and multi-channel sellers. It syncs inventory in real time, sends low-stock alerts before products run out, and uses demand forecasting to estimate reorder quantities, days of inventory left, and the ideal replenishment date. You can build POs by selecting a supplier and destination, then add products individually, via bulk CSV, or by barcode scan. Once created, POs can be sent directly to suppliers, tracked for incoming status and payment, and received partially, fully, or in batches.

Monthly pricing
Free.

Where it falls short
As a newer app, ChannelBay has less market visibility than established competitors, though it's iterating quickly based on merchant feedback.

Mimoran

Best for
Sellers who want a simple, straightforward way to create POs and restock inventory, including across multiple locations.

Core strength
Mimoran focuses on PO creation and inventory restocking. It lets you create POs, send them directly to suppliers, and receive inventory partially or fully while updating Shopify stock automatically. It also supports product transfers, CSV/PDF exports, supplier management, and scheduled low-stock alerts. Higher-tier plans add stock transfers, stocktaking, stock adjustments, returns, and automatic PO creation.

Monthly pricing

• Free: up to 5 POs/month

• Professional: $6.66/month- unlimited POs, product imports, reports, low-stock alerts, Xero integration

• Ultimate: $28.88/month- adds stock transfers, stocktaking, stock adjustments, returns, and automatic PO creation

• Both paid plans include a 7-day free trial

Where it falls short
Mimoran is built around PO creation and restocking rather than advanced inventory planning, and its more advanced operational features are locked to the Ultimate plan.

Stockie

Best for
Stores manage multiple locations or suppliers that want forecasting and purchase orders in one workflow.

Core strength
Stockie combines inventory forecasting, purchase orders, supplier management, and low-stock alerts. It uses sales history to forecast demand, predict reorder dates, and suggest reorder quantities, then lets you build POs directly from those forecasts, send them to suppliers, track shipments, and receive inventory with automatic Shopify stock updates. Multi-location inventory and real-time sync are both supported.

Monthly pricing
Starts at $4.99/month for the Basic plan (low-stock alerts, reorder calculations). Forecasting starts at $29.99/month; purchase order features require the Pro Plus plan at $59.99/month. All plans include a 14-day free trial.

Where it falls short:
Its most useful features, POs, shipment tracking, and receiving, sit behind the $59.99/month tier, and it doesn't support multi-channel selling.

Auto Purchase Order

Best for
High-volume or dropshipping sellers who want to automate PO creation from Shopify orders.

Core strength: Auto Purchase Order automates the PO workflow end to end: it can auto-create POs from incoming Shopify orders, combine multiple orders into a single supplier PO, email POs directly to suppliers, and update inventory on receipt. It also includes supplier management, incoming stock tracking, customizable PO templates, and CSV imports.

Monthly pricing

• Advanced: $39.99/month- up to 100 POs/month

• Professional: $59.99/month- up to 250 POs/month, order combining

• Enterprise: from $74.99/month- for 250+ POs/month

• All plans include a 14-day free trial

Where it falls short
It doesn't support multi-channel inventory syncing, its forecasting requires additional setup, and the entry-level plan's 100-PO cap can be restrictive for higher-volume stores.

Stockroom

Best for
Retail and POS stores that want the full purchasing-to-replenishment loop in one system.

Core strength
Stockroom covers PO creation, inventory receiving, landed cost tracking, stocktakes, stock transfers, supplier returns, forecasting, low-stock alerts, label printing, and accounting, all built around the complete restocking cycle from supplier order to shelf.

Monthly pricing
Free.

Where it falls short
Stockroom is heavily Shopify-focused with limited multi-channel coverage, a still-developing integration ecosystem, and forecasting geared toward replenishment rather than advanced demand planning.

EasyScan SKU & Barcode

Best for
Retailers and warehouses manage a large number of SKUs and physical inventory.

Core strength
EasyScan is built around barcode scanning for stocktakes, picking, packing, and order fulfillment, paired with demand forecasting and replenishment tools for warehouse-heavy operations.

Monthly pricing
Basic $9.99/month, Standard $39.99/month, Advanced $79.99/month, Pro $129.99/month, higher tiers unlock more advanced inventory, forecasting, and purchasing capabilities.

Where it falls short
It's primarily built for single-channel Shopify inventory and barcode operations, not centralized multi-channel management across platforms like Amazon or eBay.

Assisty

Best for
Multi-location Shopify merchants who want AI-driven forecasting and automated replenishment.

Core strength
Assisty uses AI-powered demand forecasting and reorder points to determine what to reorder, how much, and when. Merchants can automatically create, approve, track, and receive POs across multiple locations.

Monthly pricing
Free, Basic $19/month, Advanced $59/month, Shopify Plus $199/month.

Where it falls short
It's Shopify-focused rather than multi-channel, and its forecasting-heavy feature set may be more than sellers who just want simple PO creation need.

Prediko

Best for
Growing multi-location brands that need help deciding what, when, and how much to order.

Core strength
Prediko predicts future demand, flags what needs reordering, and helps create, track, and manage POs, with support for bulk PO editing across multiple locations.

Monthly pricing
Starter $49/month, Scale-up $119/month, Growth $199/month, plus a custom Enterprise plan. Paid plans include a 14-day free trial.

Where it falls short
Prediko's pricing and feature depth are built for forecasting-first businesses, which makes it more than merchants who just need basic PO management may require.

StockSavvy Barcode Scanning

Best for
Retailers managing physical inventory who need barcode scanning alongside PO creation.

Core strength
StockSavvy centers on creating and managing POs, deciding what to order, generating POs for suppliers, tracking incoming orders, and receiving products, with barcode scanning to speed up inventory checks on arrival.

Monthly pricing
Lite $9/month, Medium $29/month, Plus $39/month, plus a one-month pass for $159.

Where it falls short
It's Shopify-focused rather than multi-channel, and lower-tier plans cap POs, locations, and inventory items.

PML Stock Take Inventory Count

Best for
Shopify POS retailers with one or more physical locations needing basic PO management alongside stock counts.

Core strength
PML Stock Take combines basic PO management with inventory counting, merchants can create and send POs, ship and receive stock, and update inventory automatically on arrival.

Monthly pricing
Basic $10.79/month (1 location), Growth $21.79/month (3 locations), Complete $37.79/month (up to 15 locations). All plans include a 30-day free trial.

Where it falls short
It's focused on stocktaking rather than advanced purchasing, with no multi-channel support, demand forecasting, or automated reorder suggestions.

A Quick Comparison of Shopify Purchase Order Apps

What to Look for in a Shopify Purchase Order App

Choosing an app with more features than you need can complicate purchasing rather than simplify it, leading to inaccurate orders, strained supplier relationships, and missed sales from poor planning. The best purchase order app for Shopify covers the full cycle: knowing what to reorder, creating the PO, tracking it, receiving inventory, and keeping a reliable supplier and purchase history.

Forecasting

A good purchase order app should help you plan the next purchase before stock runs out, not after. It should surface reorder suggestions that flag which products need to be purchased, show days of inventory left so you know how long current stock will last, and calculate a recommended replenishment date for when the next order should go out. Together, these insights make purchasing predictable and reduce the risk of both stockouts and unnecessary overstocking.

• Reorder suggestions

• Days of inventory left

• Recommended replenishment date

Purchase Order Creation

PO creation should be quick and accurate, not a manual spreadsheet exercise prone to errors. Automatic cost and total calculations remove manual math, barcode scanning speeds up adding products, and CSV import/export makes managing large product lists in bulk realistic. Multi-location purchasing matters too, since it lets you build and manage POs for different warehouses or stores from one place instead of switching between systems.

• Easy supplier and location selection

• Automatic cost and total calculation

• Barcode scanning support

• CSV import and export

• Multi-location purchasing

Purchase Order Management

Once a PO exists, you need to know where it stands at any moment. Order status tracking tells you whether a PO is still being prepared, has been sent, or has been received, while payment status tracking keeps you on top of what's outstanding versus paid with each supplier.

• Order status tracking

• Payment status tracking

Purchase Order Receiving

Suppliers rarely ship everything in one go, so receiving needs to handle partial shipments cleanly. Partial delivery and receiving let you record only the products and quantities that have actually arrived, while automatic inventory updates keep Shopify stock levels accurate as each shipment comes in, rather than waiting for the full order to reconcile stock.

• Partial delivery and receiving

• Automatic inventory updates after receiving

Purchase Order Records

A clear purchasing history matters once you're managing more than a few suppliers. PO history and records let you quickly review past orders, while landed cost tracking gives a truer picture of what inventory actually cost once freight, duties, and other fees tied to getting stock ready for sale are factored in.

• Purchase order history and records

• Landed cost tracking

Supplier Management

Purchasing gets easier when supplier information is centralized and comparable. Support for multiple suppliers per SKU gives you flexibility to shop around, while supplier purchase history helps you evaluate the buying relationship with each vendor over time, which is useful when negotiating terms or deciding who to consolidate orders with.

• Multiple suppliers/vendors per SKU

• Supplier purchase history

Bottom Line

The right Shopify purchase order app depends less on how many features it has and more on which parts of your workflow are actually breaking down today. If you sell on multiple channels, ChannelBay or Stockie's multi-location tools are worth testing first. If you need automation for high order volume, Auto Purchase Order is built for that. If forecasting accuracy matters more than anything else, Assisty and Prediko lead on AI-driven replenishment. Match the app to the gap, not the other way around.

Frequently Asked Questions

Do I need a purchase order app if Shopify already has built-in PO tools? 

Shopify's native tools handle basic PO creation, but they don't offer demand forecasting, supplier purchase history, or barcode-based receiving. Most stores managing more than a few SKUs or suppliers outgrow the native tools quickly.

Can a Shopify purchase order app work across multiple sales channels? 

Yes, ChannelBay is built specifically for multi-channel and Shopify POS sellers. Most other apps on this list are Shopify-focused only.

What should a small Shopify store prioritize in a purchase order app? 

Small stores with a handful of SKUs generally get the most value from simple PO creation, low-stock alerts, and supplier management, features covered by apps like Mimoran, rather than paying for advanced forecasting they don't yet need.

How much do Shopify purchase order apps typically cost? 

Pricing ranges widely, from free plans (ChannelBay, Stockroom) to $9–$60/month for mid-tier PO and forecasting features, up to $199/month for enterprise-grade AI forecasting (Assisty, Prediko).

What's the difference between a purchase order app and an inventory forecasting app? 

A purchase order app focuses on creating, sending, tracking, and receiving POs. A forecasting app predicts what and when to reorder. Several apps on this list, like ChannelBay, Stockie and Assisty, combine both.
