Best purchase order apps for Shopify in 2026
Shopify doesn't have a real purchase order system built in — no supplier records, no PO-to-supplier email, no receiving workflow. If you're buying inventory from suppliers and reordering by hand or in a spreadsheet, here's how the main Shopify PO apps compare in 2026.
| App | Best for | Starting price |
|---|---|---|
| Reorda | Single-store merchants, everyday PO workflow | $19/mo flat |
| Prediko | AI demand forecasting + PO automation | $49+/mo |
| Fabrikatör | Forecasting-heavy brands, multi-warehouse | Usage-based, check current pricing |
| Inventory Planner (Sage) | Multi-location transfer planning | $119.99+/mo (Shopify plan) |
| Cin7 | Multi-channel sellers, manufacturing/BOM | $349+/mo |
| Auto Purchase Orders | Simple PO creation, dropshipping | Check current pricing |

How to choose
The apps above split into two groups, and mixing them up wastes money either direction:
- Workflow apps (Reorda, Auto Purchase Orders) — focused on the mechanics: create a PO, email the supplier, receive the shipment, get nudged when stock runs low. Cheap, fast to set up, no learning curve.
- Forecasting platforms (Prediko, Fabrikatör, Inventory Planner, Cin7) — add demand modeling, seasonality, multi-location transfer recommendations, sometimes full ERP features like manufacturing and multi-channel sync. Priced accordingly, and worth it if you actually need that depth.
A single-store merchant buying from a handful of suppliers rarely needs seasonality modeling or a warehouse management system — that's paying enterprise prices for a small-business problem. A brand selling across Shopify, Amazon and wholesale with multiple warehouses is the opposite case: the forecasting depth pays for itself.
Why merchants pick Reorda
Reorda covers the everyday PO loop — purchase orders, suppliers, receiving (including mixed shipments across multiple open POs), barcode-scanner receiving, label printing, and low-stock forecasting based on actual sales velocity and supplier lead time — for a flat $19/month with no revenue-based pricing tiers. See how it stacks up against Cin7 and Inventory Planner in detail.
Migrating off Stocky?
Reorda rebuilds your supplier database automatically from your purchase order history — the one thing Stocky never let you export. $19/month flat, 14-day free trial.

Does Shopify have a built-in purchase order feature?
Not a real one. Shopify's native inventory transfers can log incoming stock, but there's no supplier management, no PO email workflow, no receiving against partial shipments, and no low-stock-to-PO pipeline. That's the gap all of these apps fill. See our breakdown of what Shopify does and doesn't cover.
What's the cheapest purchase order app for Shopify?
Among apps with a real PO workflow (not just a basic inventory count), Reorda is the lowest flat price at $19/month. Some apps advertise free tiers, but they're usually capped by order volume or missing supplier emailing and receiving — worth checking the fine print before you rely on one.
Which purchase order app is best for a small single-store merchant?
For a single Shopify store without multi-channel or multi-warehouse complexity, a focused flat-fee app (Reorda) covers the daily workflow — create PO, email supplier, receive, get low-stock nudges — without paying for enterprise forecasting you won't use. Multi-location or multi-channel sellers get more value from Cin7 or Inventory Planner.
Do these apps require replacing Shopify's inventory system?
No. All the apps below work alongside Shopify's native inventory — they read your Shopify stock levels and write updates back through the Admin API when you receive a shipment. You don't migrate off Shopify inventory to use them.
