The 10 best purchase order software tools, by what you need

The list opens with one tool for each of the two main jobs: Sumtracker for reordering from your stock levels, and Zip for approving spend before it is committed. The tools after them are inventory-led first, then ERP.

1. Sumtracker

Best for: Shopify and multichannel sellers who want purchase orders, reorder suggestions and stock sync in one place.

Sumtracker is an inventory management, forecasting and planning platform for Shopify and multichannel brands. Its Replenish plan includes purchase orders, stock transfers, a 12-month forecast, reorder suggestions, warehouse-level permissions and a QuickBooks integration. Stock syncs across channels every few minutes.

• Purchase orders move from Draft to Incoming to Closed, and receiving updates warehouse and store stock.
• Receive a delivery in full or in parts, with one receive note per delivery.
• Pack size is checked as you add lines: ordering 3 units of a 10-unit pack shows a warning.
• Email the PO to your supplier, with up to 10 Cc recipients.
• A Plan tab lists reorder suggestions, and you create the PO from it.

Pros: purchasing, receiving and reorder suggestions in one system; transparent plans; 14-day free trial with no card.

Limits: purchase orders start on Replenish at $119/month, not on the $59 Manage plan. There are no shipping labels or fulfillment, it is not built for manufacturing or approval-heavy procurement.

2. Zip

Best for: finance and procurement teams that need approvals and spend control before a purchase order is raised.

Zip is an agentic procurement orchestration platform that goes beyond traditional PO management. It captures purchasing requests at the point of need and routes them through intelligent workflows—connecting approvals, vendor management, and downstream systems like your ERP—so every purchase order is compliant, visible, and fast. Trusted by companies like Snowflake, Coinbase, and Anthropic, Zip is built for modern teams that want control without the bottlenecks.

Key Features:

• Centralized intake for all purchase requests—no more rogue spend or email chains
• AI-powered routing sends requests to the right approvers based on spend type, amount, and policy
• Full visibility into every PO in flight, from request to receipt
• Connects with NetSuite, SAP, Oracle, Coupa, and other ERPs for seamless PO creation and sync
• Vendor onboarding and lifecycle management built into the workflow
• Real-time dashboards for finance and procurement to track spend before it happens
• Configurable approval chains with built-in compliance controls (security, legal, budget)

Pros:

• Dramatically reduces procurement cycle times—weeks become days
• Intuitive interface that employees actually want to use, driving adoption
• Orchestrates across your existing tech stack rather than replacing it
• Enterprise-grade security with SOC 2 Type II certification
• Exceptional visibility for finance teams to control spend proactively

Cons:

• Best suited for mid-market and enterprise companies with more complex procurement needs
• Initial workflow setup requires some configuration (though support is responsive)

Pricing: Custom pricing based on company size and modules

Inventory-led purchase order software for ecommerce and wholesale

3. Inventory Planner by Sage

Best for: brands whose main question is how much to buy.

Inventory Planner recommends what to order and creates and shares purchase orders. Essentials ($119.99/month) works only with Shopify and covers one location. Multiple locations, transfer and assembly orders and automated POs need the full plan, which is quoted on request.

Pros: purchasing driven by demand forecasts. Cons: not a full inventory system, and the full plan has no published price.

4. Ordoro

Best for: small brands wanting orders, inventory and shipping in one tool.

Ordoro covers vendor management, PO generation, receiving, barcode scanning and shipping labels. Plans are modular: Advanced is $59/month, inventory syncing starts on Premium ($149/month), and the Inventory Management module adds $350/month.

Pros: POs and shipping in one place. Cons: limited inventory analytics, and the cost rises once inventory modules are added.

5. SkuVault

Best for: warehouse teams that run on barcodes.

SkuVault generates POs from reorder thresholds, receives stock by barcode and tracks supplier deliveries, with links to Shopify, Amazon and eBay. Pricing is by quote only.

Pros: built for warehouse accuracy. Cons: a dated interface that can be complex for small teams.

6. Zoho Inventory

Best for: small teams already using Zoho.

Zoho Inventory generates POs from low stock, manages suppliers and price lists, and supports backorders and dropshipping, with Zoho and Shopify sync. A free plan covers 50 orders a month, and Standard is $29/month billed annually.

Pros: affordable. Cons: works best inside the Zoho ecosystem, with order limits on each plan.

7. Cin7 Core

Best for: wholesalers and high-volume sellers with complex purchasing.

Cin7 Core offers PO workflows, landed cost and tax-inclusive pricing, dropshipping and backorders, and integrations with Xero, Shopify and Amazon. Standard is $349/month, and workflow and approval automations arrive on Pro at $599/month.

Pros: powerful and strong for wholesale. Cons: a steep learning curve, and onboarding help is usually needed.

8. Unleashed

Best for: manufacturers, wholesalers and food brands that need batch tracking.

Unleashed supports multi-supplier POs, partial receipts, landed cost and margin tracking, and batch and expiry tracking. Lite is $99/month, Core $399 and Pro $729, each with a 14-day trial.

Pros: strong traceability and costing. Cons: can overwhelm newcomers, with a dated interface.

What if a supplier ships your order in parts?

Suppliers rarely ship exactly what you ordered: a carton comes up short, an item arrives damaged, or the rest is on backorder and will not ship at all.

A PO that can only be received in full leaves stock counts wrong while the remainder is in transit, and your store may oversell or undersell in the meantime.

In Sumtracker, you choose Receive all products or Receive products partially. Each delivery gets its own receive note, warehouse and store stock update when the note is final, and the PO closes once everything has arrived.

Procurement-led or inventory-led: which kind of PO software do you need?

Purchase order software splits into procurement-led and inventory-led tools, and most buying mistakes come from choosing the wrong kind. If you sell physical products across a Shopify store or several channels, start with the inventory-led group.

9. Odoo Inventory

Odoo is an open-source, modular ERP with customizable PO rules, vendor management, lead times and vendor bills. Pricing is about $31 per user per month.

Pros: flexible, and you pay for the apps you use. Cons: needs technical setup.

10. NetSuite ERP

NetSuite is an enterprise ERP with custom approval workflows, three-way matching, multi-currency support and vendor scorecards. Pricing is by quote.

Pros: scales to global procurement. Cons: expensive and slow to set up for smaller teams.

Best purchase order software compared (2026)

Each tool was checked on six points: whether it creates POs from stock levels, whether it receives deliveries in parts, landed costs, channel sync, accounting links, and what it costs at small-business volume.

How should purchase orders connect to accounting?

Check three things before you buy: whether the tool pushes bills or POs to your accounting software or only reads from it, whether it carries landed costs such as shipping and duties into cost of goods, and which plan includes the integration. Integrations are often limited to higher plans, so confirm the plan as well as the logo.

Frequently asked questions

What is purchase order software?

Purchase order software is a tool that creates, sends, tracks and receives purchase orders. It records what you ordered, from which supplier, at what price and what has arrived, so stock and spend stay accurate without spreadsheets.

What is the difference between a purchase order and an invoice?

A purchase order is the buyer's request for goods, sent before delivery. An invoice is the supplier's request for payment, sent after the goods ship. Matching the two, plus the delivery record, prevents paying for items you did not order or receive.

Is there free purchase order software?

Yes, in limited form. Zoho Inventory has a free plan for up to 50 orders a month. Most other tools in this list start on a paid plan or a free trial, so check order limits before relying on a free tier.

What is the best purchase order software for a small business?

For a small business that sells products, an inventory-led tool such as Zoho Inventory or Sumtracker usually fits best, because purchase orders tie directly to stock. Procurement suites suit teams that need approvals more than stock tracking.

Can purchase order software track inventory?

Yes, inventory-led tools do. Receiving a purchase order adds stock to the right warehouse and can update your sales channels. Procurement-led tools usually record the order and hand stock tracking to a separate ERP or inventory system.

What is three-way matching?

Three-way matching compares the purchase order, the goods receipt and the supplier invoice before payment is approved. It stops you paying for items you did not order, did not receive or were charged for at a different price.
