Is Synplex a direct replacement for Stocky by Shopify?

Yes. Synplex covers demand forecasting, reorder recommendations, purchase orders, and supplier management - the core planning workflows Stocky provided - inside an actively maintained Shopify-native app.

When does Stocky shut down?

August 31, 2026. After that date, Stocky will no longer be accessible. Shopify has confirmed there is no direct native replacement for its forecasting and replenishment features.

Does Synplex feel significantly heavier than Stocky?

Synplex adds forecasting depth and structured supplier management that Stocky lacked, but it is still a focused Shopify app - not an enterprise platform. The main adjustment for Stocky users is moving from threshold-based reorder nudges to demand-driven replenishment signals. Most users find the new model more useful once they are familiar with it.

Can I transfer my Stocky data to Synplex?

Shopify product data, inventory levels, and sales history sync automatically. Stocky supplier records are not exportable and must be recreated in Synplex - a one-time setup task during onboarding, not an ongoing burden.

Synplex vs Stocky by Shopify: which one is right for your Shopify brand?

This is not a close comparison. Stocky is being shut down and Shopify is not replacing its planning layer. Synplex covers the same core jobs - demand forecasting, reorder suggestions, purchase orders, and supplier management - inside a Shopify-native app that is actively developed. The only real question is timing: teams that depend on Stocky for buying decisions should migrate before the operational pressure of a deadline forces them to. Teams that only use Stocky for basic retail counts or admin have more runway, but the deadline is fixed either way.

Synplex is best for

Any Shopify brand that currently relies on Stocky for reorder suggestions, purchase orders, or inventory planning before August 31, 2026.
Teams that want to move from threshold-based reorder logic to demand-driven replenishment that accounts for seasonality and lead times.
Merchants who want to replace Stocky without adopting an enterprise platform - staying inside Shopify with a focused planning tool.
Operations that want structured supplier management and PO workflows embedded in their planning process.

Stocky by Shopify is best for

Merchants in the final weeks of a planned migration who only need Stocky for basic purchase orders or retail admin during the transition window.
Stores with minimal forecasting needs that are already using another tool for replenishment and only need Stocky's retail admin features briefly.

Feature breakdown

Synplex vs Stocky by Shopify: side-by-side

A detailed feature comparison for Shopify brands evaluating both platforms.

Feature	Synplex	Stocky by Shopify
Platform & Ecosystem
Product status	Actively developed Shopify app with ongoing investment in forecasting and replenishment workflows.	Officially deprecated by Shopify. Access ends August 31, 2026.
Long-term viability	Built as a standalone inventory planning product with a clear product roadmap for Shopify brands.	No future development. Shopify is not building a direct native replacement for Stocky's planning features.
Forecasting & Demand
Demand forecasting	Forecasts from Shopify sales history, accounting for seasonality, trends, and supplier lead times.	Forecasting features are being removed as part of the deprecation. Not a viable path forward.
Replenishment suggestions	Demand-driven reorder recommendations that reflect sales velocity, lead times, and safety stock logic.	Min/max threshold logic. Does not model actual demand patterns or supplier-specific lead time variation.
Purchasing & Execution
Purchase orders	POs created from replenishment signals in one workflow - no export or manual bridging step.	Available today but shutting down in August 2026. Not a durable purchasing workflow.
Supplier management	Supplier records, lead times, and MOQs tracked inside the replenishment workflow.	Supplier data is not portable from Stocky. Records must be rebuilt in any replacement system.
Analytics & Usability
Inventory analytics	Stockout risk, sell-through, overstock positions, and supplier performance reporting within the planning workflow.	Useful for basic retail operations. Not designed as a forward-looking planning or analytics tool.
Operator experience	Built for lean Shopify teams - fast setup, guided action, clear replenishment signals.	Familiar for existing users, but the planning surface shrinks toward the shutdown date as features are removed.
Support & Maintenance
Planning model quality	Demand-driven forecasting from actual sales patterns - not static thresholds.	Min/max logic does not adapt to demand changes, seasonal variation, or lead time shifts without manual adjustments.

In depth

The real differences between Synplex and Stocky by Shopify

What Shopify Is Actually Removing

Stocky's shutdown removes more than an app. It removes the reorder suggestion logic, purchase order tracking, and inventory planning workflows that many merchants have embedded into their weekly buying rhythm. Shopify's native admin does not replace those capabilities - it handles inventory counts and basic retail operations, not demand forecasting or supplier-aware replenishment. Brands that relied on Stocky for buying decisions need a dedicated replacement, not just a new app icon.

Threshold-Based Reordering vs Demand-Driven Planning

Stocky's model was simple by design: set a minimum stock level, get a nudge when inventory falls below it. That works for stable, predictable SKUs. It breaks down when demand is seasonal, when lead times vary by supplier, or when a promotion creates a spike that static thresholds cannot anticipate. Synplex models actual sales patterns and accounts for supplier lead times, so reorder signals reflect what demand is likely to do rather than just where inventory sits right now.

Why Migration Timing Matters

Switching inventory planning tools mid-season or under deadline pressure is operationally harder than switching during a slower period. The risk is not just losing access to an app - it is disrupting buying habits and planning cadences at the worst moment. Synplex pulls Shopify data automatically, and most merchants complete initial setup within a day or two. Early migration gives your team time to build familiarity with the new workflow before it becomes urgent.

Who Can Still Wait - and for How Long

If your team uses Stocky only for physical retail counts, basic admin, or occasional purchase order reference, you have more time before the deadline creates operational pressure. But brands whose weekly buying decisions flow through Stocky's reorder suggestions or PO workflows have less buffer than they think. Planning tools take a few weeks to feel natural. Migrating in July 2026 leaves almost no time to build those habits before August 31.

Pricing & value

How Synplex and Stocky by Shopify compare on cost

Synplex

Shopify app subscription covering forecasting, replenishment, purchase orders, and supplier management. Self-serve setup, no implementation project.

Stocky by Shopify

Previously bundled with Shopify retail at no additional cost. That access ends permanently on August 31, 2026.

Synplex adds a subscription cost that Stocky did not carry. It also replaces the planning work that typically surrounded Stocky - reorder spreadsheets, manual supplier follow-up, and reactive stock decisions - which has a real operational cost of its own.

Making the switch

What the Transition from Stocky to Synplex Involves

Synplex connects directly to Shopify, so product catalog, inventory levels, sales history, and location data import automatically - no export or data wrangling required. The main manual work is supplier records: Stocky does not export supplier data, so lead times, MOQs, and vendor contacts need to be set up in Synplex as a one-time configuration step. Most merchants complete setup and run their first replenishment review within one to two days.

One to two days for most Shopify-only operations. Larger catalogs or many suppliers may take an additional day.

Typically owned by: Typically managed by an operations lead or inventory manager. No technical implementation required.
