Top Demand Forecasting Apps for Shopify (2026)
Forecasting is the difference between ordering the right amount and guessing. Get it right and you free up cash, avoid stockouts on your bestsellers, and stop discounting dead stock. Get it wrong in either direction and it costs you — overstock ties up capital, understock hands sales to a competitor. This is the operator shortlist for demand planning on Shopify, ranked on reputation, fit, and first-hand feedback from the app store research network where we have it.
A note on the data: forecasting is a specialized back-office category, so our review sample is small. We lead with each tool's reputation and mechanics and add operator quotes where we have them, flagged as such. Treat the operator voices as directional signal, not statistics — and treat every forecast the same way.
Stocky shut down: where does Shopify demand forecasting live now?
Stocky, the free planning app many Shopify POS brands used for demand suggestions and reorder points, stopped working on August 31, 2026. Shopify's built-in inventory tools now handle purchase orders, transfers and stock counts, but they don't forecast demand or suggest what to reorder. If Stocky did that job for you, you need one of the tools below.
Before you switch, export what you need from Stocky. Read-only access lasts at least 90 days after shutdown, and suppliers can't be exported, so copy those by hand. Shopify's Stocky migration guide covers the native side, and our inventory apps guide covers the wider stack.
Forecasting apps at a glance
# | App | Best for | ASR signal |
|---|---|---|---|
1 | Inventory Planner | Dedicated demand forecasting & POs | "Helps me forecast how much to order" |
2 | Cin7 Core | Forecasting inside a broader ops system | "100x better than NetSuite for 1/10 the price" |
3 | Genie | Simple planning, forecasting maturing | PO info in one place |
4 | Bee Low Stock Alert & Forecast | Lightweight stockout alerts | Free tier for run-out notifications |
Most brands need exactly one forecasting tool, matched to how complex their purchasing actually is. Don't over-buy: a lightweight alert app may be all a small catalog needs, while a multi-channel operation wants real forecasting inside a system of record.
1. Inventory Planner — dedicated demand forecasting
The category's best-known dedicated forecaster. It projects demand from sales history, recommends reorder quantities, and turns those into purchase orders — the tool most brands graduate to when spreadsheet planning breaks down. The honest limitation, named by operators, is the one every forecaster shares: models struggle when history is short or demand spikes.
What operators love (from our network): forecasting order quantities, creating POs, and receiving/updating inventory in one flow; a real step up from spreadsheet planning. Common concerns: forecasts can overshoot after an initial spike on a new product, suggesting you keep reordering at the spike rate.
"Having a tool that helps me forecast how much inventory I need to order is very valuable — planning orders in software instead of spreadsheets." — Owner, verified ASR review

2. Cin7 Core — forecasting inside a broader system
If you want forecasting as part of a full inventory-and-operations platform rather than a standalone app, Cin7 Core builds demand planning into a system that also runs purchasing, wholesale, and multi-channel stock. Best for brands whose complexity has outgrown point tools.
What operators love (from our network): far cheaper and more manageable than legacy enterprise systems, with self-serve debugging. Common concerns: can slow at month-end; more system than a brand needs if forecasting is the only goal.

3. Genie — simple planning, forecasting maturing
A newer, simpler tool for brands that want clean PO management now and are betting on its roadmap. Operators like the streamlined purchasing today and are explicitly waiting on deeper demand-forecasting features — so weigh it on where it's going as much as where it is.
What operators love (from our network): all PO information in one place instead of scattered across spreadsheets. Common concerns: demand-forecasting and accounting (QBO) connections are still on the roadmap.
"The ability to have all the important information for a PO in one place instead of tracking across multiple spreadsheets." — Operations, verified ASR review
4. Bee Low Stock Alert & Forecast — lightweight alerts
The minimal option: a free tier that simply tells you when products are running low. Not a full forecaster, but for a small catalog where the only real need is "don't let bestsellers hit zero," it does the job without cost.
What operators love (from our network): the free version's run-out notifications are genuinely useful. Common concerns: the free tier is limited, and operators weren't always convinced the paid forecasting features justified the upgrade.
"I use the free version to get notified when products run out of stock." — Owner, verified ASR review
How to choose a forecasting tool
Match the tool to the complexity of your purchasing, not to feature lists. On Shopify POS with a simple catalog? Now that Stocky is gone, Shopify's built-in purchase orders plus a free stockout alert are enough to start. Purchasing decisions genuinely painful and spreadsheet-bound? Inventory Planner is the dedicated answer. Multi-channel or manufacturing complexity? Forecasting belongs inside Cin7 Core. Small catalog that just can't afford a stockout on bestsellers? A free alert tool like Bee covers it.
One honest caveat that applies to every tool here: a forecast is a projection, not a promise. All of them wobble on new products, seasonal spikes, and viral demand. Use them to replace guesswork, not judgment — and sanity-check the number before you commit the cash.
