Shopify Sidekick Inventory Management: What It Can (and Can't) Do in 2026
Last updated: November 5, 2026
Quick answer: Shopify now documents Sidekick forecasting, demand-based purchase-order drafts and inventory-transfer recommendations. It should not be dismissed as only a reactive stock-query tool. Check the data, forecast horizon, constraints and review steps available in your store before deciding whether another planning app is needed. Forthcast publishes this guide and is one of the products discussed.
TL;DR: Sidekick can analyze Shopify data, help build Flow workflows and prepare changes for review. Some capabilities vary by store, and Pulse has its own eligibility requirements. Compare those workflows with Forthcast's eligible SKU forecasts, supplier settings and merchant-reviewed purchasing. Neither a conversational response nor a dedicated forecast guarantees the correct order or avoidance of a stockout.
What Shopify Sidekick Actually Does for Inventory
Sidekick is Shopify's built-in assistant for questions, analysis and tasks in the admin. The current Shopify guide says it can work through multi-step tasks, build Flow workflows and run code to forecast or summarize store data. Code execution is not available in every store, so check what your own account supports.
"Supply chain has definitely been kind of an Achilles heel of ours. I feel like every time we've started to gain real momentum, we've encountered challenges around supply chain."
For inventory, use Sidekick to investigate a specific question, then inspect the records and assumptions behind the answer:
- Stock queries: Ask which variants are below a stated quantity, then check the locations, inventory states and update time included in the response.
- Sales analysis: Ask for a sell-through or sales comparison and check the period, product set and metric definition before using it to change a purchase.
- Filtering: Ask for products without recent sales, then distinguish new launches, stockouts and seasonal items before treating the list as dead stock.
- Flow preparation: Shopify documents Sidekick building Flow workflows. Review the trigger, conditions, permissions and actions before activating a low-stock notification or another repeated task.
Test a representative task and compare the work required to prepare and review the result. This page does not report measured time savings or an accuracy benchmark for either product.
Sidekick Pulse: The Proactive Inventory Feature
Sidekick Pulse presents personalized recommendation cards on Shopify Home. Shopify currently limits it to some stores with recent sales activity, requires owner or admin access, and requires Shopify Network Intelligence to be enabled. A Pulse card is not a guarantee that every low-stock condition will trigger an alert.
"So we've tried a couple apps, for inventory management and for production management. One of them was called Katana, which was actually pretty great until we had way too many orders for it to support."
"the foundation and why these problems continue to exist—we haven't found a viable solution for"
Shopify's current inventory transition guide describes asking Sidekick to rebalance stock across locations and draft a transfer. It does not support treating every such workflow as Shopify Plus-only. Confirm your store's permissions, available tools and the products and locations included.
Compare the recommendation and the action you need to take, rather than assuming Sidekick only describes the present while Forthcast predicts the future. Both require a review of data, assumptions and the proposed purchase or transfer.
What Changed in 2026: Sidekick’s Editions Updates and the Forthcast Extension
Shopify documents using Sidekick for demand-informed purchase-order suggestions and drafts. Its built-in inventory tools also handle suppliers, purchase orders and linked transfers. Verify the resulting quantities and workflow instead of treating a dedicated forecasting app as a mandatory replacement for every Stocky user.
Sidekick's current documentation describes multi-step work, saved skills and forecasting with code in supported stores. Those capabilities make a categorical claim that it cannot forecast too broad. They do not establish that every store has the same tools, an identical recurring model or a validated 12-month forecast.
If a Sidekick integration is a requirement for choosing Forthcast, confirm current availability and supported tools with Forthcast first. The integration is designed to provide SKU status, replenishment suggestions and open-purchase-order information. Do not assume installing the app proves that those tools are enabled in your Sidekick chat.
Illustrative planning conversation, retained as an example rather than a current integration acceptance test:
You: What should I reorder?
Sidekick (via Forthcast): Sorted by revenue at risk —
- Already oversold, PO on the way → “Trail Mix Pouch” is 40 units oversold, but an open PO of ~5,600 units is in transit (60-day lead time) — no additional reorder needed.
- Oversold, no PO → “Starter Bundle” is 260 units oversold with no open PO — order ~340 units now.
- Out of stock → “Focus Capsules” is at zero — suggested reorder ~90 units.
Open supply matters when reviewing a reorder. Check the expected arrival, quantity and demand it is meant to cover; the existence of a purchase order alone does not prove a shortage is covered in time. The example above is not a measured test of either product.
Planning Capabilities to Verify
Use these questions to assess planning fit. Shopify's documented capabilities have expanded, so unsupported blanket negatives are not a reliable comparison. Inspect the actual output, data and actions available for your store.
Forecast Horizon and Validation
Shopify documents forecasting with code in supported stores and demand-based buying suggestions. Ask for the period, input data, method and error checks behind an output. Forthcast provides eligible SKU forecasts up to about 12 months ahead; that horizon does not establish equal accuracy throughout the year. This page has not measured equivalent forecast results across the two products.
Supplier Lead Times and Order Constraints
Review which supplier constraints and product data a draft uses. Shopify documents minimum/maximum thresholds through metafields and Sidekick-assisted draft transfers or purchase orders; that is not the same as proving every supplier rule is configured automatically. Forthcast's supported purchasing workflow can apply configured lead times, MOQ and case-pack rules, but the merchant still checks the quantities.
Purchase Orders: Drafting and Review
Sidekick can help draft a Shopify purchase order, and Shopify also documents Flow workflow preparation. Verify the actual trigger, review step and purchasing action you need rather than assuming a standing replenishment loop exists or is impossible. Forthcast provides purchasing recommendations and drafts; review open supply and choose whether to approve and send the order.
Revenue-at-Risk Methods
Forthcast's revenue-at-risk figure is an estimate based on planning data, not the amount a shortage will certainly cost. For any analysis produced through Sidekick, ask what data and assumptions support the figure. This page does not establish a like-for-like risk model or a categorical inability to calculate an estimate.
Thin Data Limitations
Limited history, censored sales and low sales volume need review regardless of the tool. This page has no measured evidence that Sidekick becomes unreliable below a universal 12-month threshold. In Forthcast, new-product references are merchant-chosen and seed recommendations require review; they do not remove launch uncertainty.
Multi-Warehouse Complexity
Shopify documents location rebalancing and draft-transfer workflows. Check the permissions, locations, stock states and fulfillment requirements of the specific task. For Forthcast, location stock views and advisory transfers are different from independent demand forecasts for every warehouse or automatic channel allocation.

The Right Framing: Complementary, Not Competitive
Start with the workflow you need: investigating current stock, producing a forecast, applying supplier constraints or reviewing a purchase. The products may overlap in some tasks and differ in their data, controls and implementation.
- With Sidekick, inspect the analysis and proposed changes in Shopify. Check permissions, inputs and any store-specific feature limitations before relying on an answer or activating a workflow.
- With Forthcast, inspect forecast coverage, supplier settings, risk estimates and the draft order. Store-wide forecasts and a proposed quantity support a decision; they do not tell you with certainty what will happen or place an order autonomously.
Try your actual planning task with the native Shopify workflow first. Add another product when its verified coverage, constraints or review process address a requirement that remains unmet, and compare the total work and cost.

Stocky Transition: What to Check Now
Stocky stopped being available for inventory management on August 31, 2026. Shopify says read-only export access remains for at least 90 days after that date; Stocky APIs stopped on August 31. Check the current migration instructions for the records and workflows you still need to move.
The August deadline has already passed. Export needed records while access remains available, and confirm how your team now creates, receives and reconciles orders in the replacement workflow.
Shopify now documents native purchase-order, supplier and transfer workflows, with Sidekick helping produce demand-based drafts. Some Stocky-specific features differ, so test the work you actually relied on. Choose an additional app where a verified requirement remains; do not assume Sidekick only answers conversational stock questions.
