Stocky alternatives compared
| Tool | Best for | Limitations |
|---|---|---|
| Synplex | Shopify merchants who want a demand plan, replenishment recommendations, supplier lead times, and purchase-order workflows without moving to a full ERP. | Early-stage app; best for merchants willing to shape the workflow and provide feedback. |
| Inventory Planner | Teams that want mature forecasting and reporting workflows. | May be more planning and reporting-heavy than smaller merchants need. |
| Prediko | Brands looking for forecasting and replenishment planning in a modern Shopify app workflow. | Merchants should evaluate whether it covers the exact PO, supplier, and Stocky replacement workflows they need. |
| Katana | Merchants with manufacturing, production, or MRP complexity. | May be heavier than needed for merchants primarily replacing Stocky-style buying workflows. |
| Shopify native inventory | Simple stock tracking and smaller catalogs. | Does not fully replace Stocky-style planning, supplier, PO, and replenishment workflows. |
| Spreadsheets | Very small catalogs or temporary migration planning. | Fragile once SKU count, suppliers, lead times, or reorder frequency increase. |
Who this guide is for
Shopify merchants using Stocky for purchase orders, stocktakes, supplier tracking, low-stock reviews, reporting, or replenishment decisions who need to choose a replacement before the August 31, 2026 shutdown.
The challenges of scale
Stocky replacement planning is not only about finding another app; merchants need to preserve the weekly buying workflow that connects low-stock reviews, suppliers, purchase orders, receiving, and reporting.
Many replacement lists mix ERP, manufacturing, reporting, and spreadsheet options without explaining which workflows actually replace Stocky.
Supplier records and planning assumptions need to be rebuilt carefully because they are often the operational memory behind reorder decisions.
Teams need enough time to test purchase orders, receiving, inventory adjustments, and reporting before Stocky access changes.
Fundamental concepts
Stocky alternative
A Stocky alternative is a Shopify inventory planning tool or workflow that replaces Stocky functions such as purchase orders, supplier tracking, stocktakes, demand planning, inventory reporting, and replenishment decisions.
Example: A merchant that used Stocky for reorder suggestions and supplier purchase orders should evaluate whether the replacement can manage supplier lead times, draft POs, receiving, and stockout risk in one workflow.
Demand plan
A demand plan estimates what products a merchant is likely to need, when they should reorder, and how much they should buy based on sales history, current stock, supplier lead times, and replenishment assumptions.
Example: If a bestseller sells 12 units per day and the supplier lead time is 30 days, the demand plan should flag reorder timing before the product reaches the danger zone.
Why native Shopify isn't enough
While Shopify is a strong commerce engine, its native inventory tooling often reaches a limit once brands need better forecasting, replenishment logic, supplier workflows, and purchasing discipline.
- Shopify native inventory is useful for product and inventory tracking, but it does not fully recreate Stocky-style supplier, PO, stocktake, forecasting, and replenishment workflows.
- Merchants replacing Stocky usually need a place to connect sales velocity, supplier lead times, reorder recommendations, open POs, and receiving decisions.
- A simple catalog can stay close to native Shopify for longer, but larger teams usually need a structured planning workflow before buying decisions become spreadsheet-heavy.
