Quick Summary
The best purchase order software for a Shopify brand tells you what to reorder, from which supplier, and by when. Then it tracks each PO until you've received the stock in Shopify. Forstock, Prediko, and Fabrikatör do both jobs best, so they're our top three.
| Tool | Best For | Starting Price |
|---|---|---|
| Forstock | Forecast, reorder date, and PO in one plan | $79/month |
| Prediko | Multi-store brands planning a year of POs | $49/month |
| Fabrikatör | Small teams with 50+ SKUs leaving spreadsheets | $99/month |
Where Stockouts and Overstock Start
Out-of-stocks and overstocks cost retailers $1.7 trillion a year, according to IHL Group's 2026 study, and empty shelves make up 65.6% of that. For a Shopify brand, both often start with a purchase order that went out late or was seized from a spreadsheet that's out of date.
Stocky, the app that came with Shopify POS Pro, handled purchase orders until it shut down on August 31, 2026. If you used it, you'll need a new home for your suppliers and POs. So, which tools work out what to order and when, and which only track a PO once you've placed it?
Why Listen to Us?
Since switching to Forstock, Ezz Studios in Paris has about 40% fewer stockouts and saves about 5 hours a week it used to spend in spreadsheets. Gentlehomme, a menswear brand in North Miami, has ~50% fewer stockouts on its core styles and ~20% less cash tied up in overstock. Our founder, Rami, was VP of Sales at a digital freight forwarder, then built Forstock to take each reorder from forecast to supplier PO. That's the same job we judged every tool here on.

1. Forstock
Forstock is an AI inventory planning platform for Shopify brands that forecasts demand, identifies stock risks, and recommends what and when to reorder. It turns those recommendations into purchase orders across suppliers, stores, warehouses, and sales channels.
Forstock walks each SKU forward day by day at each location, using stock on hand, the forecast, and the POs already on their way. Supplier lead times connect the forecast to reorder timing. For example, a product with four weeks of stock remaining needs attention if its supplier takes six weeks to deliver. Forstock works back from the day the product runs out to a should-order-by date, then rounds the order up to the supplier's MOQ and pack size.
When you're ready to buy, you select the rows and Forstock drafts one purchase order per supplier. Separate forecasting and PO tools require you to transfer those figures or maintain integrations between them. Forecast quality still depends on the data and assumptions behind it. That's why you can open any number to see what went into it, and type over it when a promo or launch is coming.
Key Features
- Demand Planning: Forecast each SKU by location and channel up to 12 months out, corrected for stockouts and promos
- Supplier Rules: Set each supplier's lead time, MOQ, and pack size, and bulk-edit hundreds of products at once
- Purchase Orders and Suppliers: Email POs and track each one from draft to received
- Partial Receiving: Receive line by line and split a PO across deliveries or locations
- Landed Cost: Add freight, duty, and insurance to see landed cost per unit

Pick The Tool That Matches How You Buy
If you only send POs and receive stock, Shopify's built-in purchase orders or a simple PO app will do. But, if you want the system to work out what to order and when, you'll want one that forecasts.
If forecasting and purchase order management need to operate as one workflow, evaluate Forstock using your own catalog, lead times, and order history. Start a 14-day free trial with no credit card, or book a 20-minute demo.change.
FAQs
Does Shopify Have Built-in Purchase Orders?
Yes. Shopify's admin has purchase orders under Products, and stock comes in through a linked transfer that handles partial shipments. But, you can't email a PO from the admin, only export a PDF. Also, lead times and MOQs aren't built-in fields.
What Replaced Stocky for Purchase Orders?
Shopify points Stocky users to the admin's built-in purchase orders after Stocky shut down on August 31, 2026. You couldn't export suppliers, and you can't import old POs. So, you'll need to rebuild suppliers in your new tool. Our guide to replacing Stocky's PO workflow covers the switch.
How Do I Know When to Reorder from a Supplier?
Reorder when stock hits your reorder point, which is the average daily sales times the supplier's lead time, plus safety stock. Supplier lead-time tracking measures how long each vendor takes to produce and deliver an order. If you sell 10 units a day, with a 30-day lead time and 7 days of safety stock, you'd reorder at 370 units.
How Do I Handle a Partial Delivery on a Purchase Order?
Receive what arrived line by line, and keep the PO open until the rest arrives or you've canceled it. In Shopify's admin, you accept, reject, or cancel each item on the linked transfer, and every tool on this list tracks partial receipts too.
How Does Purchase Order Management Differ from Inventory Management?
Inventory management records stock on hand, while purchase order management creates, tracks, and receives orders placed with suppliers. The two meet at receiving, when a PO's delivered units become stock you can sell.
