Top 10 Purchase Order Management Softwares

Ever had that sinking feeling when a best-selling product goes out of stock, and you realize the reorder never went through?

You’re not alone.

As your business grows, managing purchase orders with sticky notes and spreadsheets just doesn’t cut it anymore.

You need something smarter.

Whether you're running a Shopify store, managing multiple warehouses, or handling custom orders, a good PO management app can take the chaos out of reordering and give you complete visibility into what’s coming, when, and from whom.

Let’s explore 10 of the best tools built to do exactly that.

Why Purchase Order Management Matters

In any inventory-driven business, managing purchase orders isn't just about paperwork, it's about survival. If you don't know what’s on order, when it's arriving, or how much it costs, you're operating in the dark. That’s risky territory when customers expect fast delivery and out-of-stock items can cost you sales.

A good purchase order (PO) management system ensures that:

• You never miss a reorder. It tells you exactly when to restock and how much to order.
• You stay organized with suppliers. Every order, delivery, and invoice is tracked, no more digging through emails.
• You control costs. With visibility into product pricing, shipping charges, and landed costs, you're always aware of your margins.
• You avoid overstocking and understocking. Smart PO systems sync with real-time inventory data to prevent costly mistakes.

Key Features to Look for in a Purchase Order Management System

Not all purchase order systems are created equal. The right one can save you time, reduce stockouts, and make your inventory operations far more predictable. But how do you know what features actually matter?

Here’s what to look for in a solid PO management tool especially if you're managing physical products across multiple channels or suppliers:

Automated Purchase Order Creation

The best systems let you auto-generate POs based on stock levels, sales velocity, or reorder points. This eliminates guesswork and helps you reorder the right products at the right time before you run out.

Partial and Full Receipts

Suppliers often send items in batches. Your system should allow partial receipts so you can track exactly what has arrived and what’s still pending, without throwing off inventory accuracy.

Real-Time Inventory Sync

When you receive stock against a PO, your inventory should update instantly across all connected sales channels. This is critical for avoiding overselling and keeping customers happy.

Supplier and Cost Tracking

Good PO systems store supplier info, pricing, lead times, and more, so you always have vendor data at your fingertips. Bonus if it helps calculate landed costs to protect your profit margins.

Seamless Integrations

Make sure your PO system integrates smoothly with platforms you already use like Shopify, Amazon, QuickBooks, Xero, or your warehouse management tool. This reduces manual work and errors.

We’ve rounded up 10 of the best apps to keep your purchase orders in check.
