Never stock out.
Never over-order.
Supplana puts inventory planning on autopilot: it forecasts demand for every SKU, turns that into your supply plan, and projects exactly what you'll spend and when. Fortune 500-grade planning — without the spreadsheets, the guesswork, or the headcount.

Demand forecast — Black Tee / M
Units per week
- Actual sales
- Trend-aware forecast
- 95% confidence band
From install to your first forecast in under 5 minutes
A guided three-step wizard does the setup. No CSV wrangling, no consultant, no onboarding call.
-
Connect your store
Install from the Shopify App Store and approve access. Supplana runs embedded inside your Shopify admin.
-
Sync your history
Your products, sales history, and stock levels sync automatically — nothing to upload or map.
-
Get your buying plan
Forecasts, reorder points, and urgency-ranked recommendations are generated for every SKU you track.
Then Supplana keeps working for you: alerts when a SKU needs attention and a plain-English weekly digest of what to reorder.
One forecast drives everything — automatically
Supplana doesn't hand you a report and wish you luck. It re-forecasts every SKU as new sales come in, rebuilds your supply plan from the forecast, and projects the spending that plan implies — the same planning cycle Fortune 500 supply chains run, fully automated for your store. You review and approve; the system does the planning.
-
Automatic
Forecast demand
Every SKU gets a trend-aware forecast that updates as new sales come in. Better forecasts are the root of everything downstream.
→ Fewer stockouts -
Automatic
Build the supply plan
The forecast becomes a buying and production plan — what to order, how much, and when — with your lead times and safety stock built in.
→ Less cash tied up in stock -
Automatic
Project the spend
The plan becomes a cash-flow projection: exactly how much you'll need to spend on inventory, and in which months.
→ Growth you can plan for
See your next 150 days of inventory — before they happen
Most tools show you a static "days remaining" number. Supplana simulates your whole replenishment cycle: stock draining, purchase orders firing at your reorder point, and shipments landing — so you can see exactly how your plan plays out.
Inventory simulation — Black Tee / M
Projected units on hand, next 150 days · lead time 15 days · order qty 350
- Projected stock
- Order placed
- Shipment arrives
- Reorder point
Your buying plan, ranked by urgency
Reorder points, days of supply, and smart "Buy now / Order in X days" labels — aware of your lead times and safety stock. Edit quantities and dates inline, then export the plan as CSV for your purchasing team.
| SKU | Status | Days of supply | Recommendation | Order qty | Order by |
|---|---|---|---|---|---|
| HOODIE-GRY-L | Out of stock | 0 | Buy now | 480 | Today |
| BLK-TEE-M | Critical | 9 | Buy now | 350 | Today |
| CAP-NVY-OS | Order soon | 21 | Order in 6d | 200 | Jul 8 |
| SOCK-WHT-3PK | On track | 64 | No action needed | — | — |
Dashed cells are editable inline — tweak a quantity or date and the whole plan recalculates.
Forecasts that actually track your trajectory
Flat moving averages under-order your growing products and over-order your declining ones. Supplana uses Holt's Linear Exponential Smoothing, so trending SKUs get sloped forecasts with 95% confidence bands.
- Growing and declining SKUs get forecasts that follow the trend
- 26-week forward demand outlook per SKU, grouped by week
- Transparent model — see actual history plotted against the forecast, not just an output number
- Demand overrides: bump the forecast for promos, events, and sales the model can't know about
Know where to focus before you spend a dollar
Every SKU is tiered A/B/C by revenue contribution and placed in a Winner / Star / Chaser / Loser quadrant — so buyers spend their attention (and cash) on the products that deserve it.
- A/B/C tiers computed automatically from your sales history
- Quadrant view combines revenue weight with trend direction
- Overstock & dead-stock flags show the dollars tied up in slow movers
ROI you can see on day one
Supplana quantifies the money at stake the moment your history syncs — before you change a single order.
- Estimated lost revenue from past stockouts
- Inventory turns and tracked-SKU KPIs
- Cash tied up in overstock and dead stock, in dollars
Projected inventory spend
Next 6 months, derived from your supply plan
See the money before you have to spend it
Because Supplana builds your supply plan for you, it knows what that plan costs. It projects your inventory spend month by month — so the Q4 buy never ambushes your bank account.
- Monthly inventory spend projected straight from your buying plan
- See big seasonal buys months ahead and line up the cash
- Plan growth, financing, and promotions around real numbers
A demand planner, a supply planner, and an analytics team — in one app
Fortune 500 supply chains employ whole teams to do this work. Supplana wraps the same best-in-class discipline into software that runs it for you — so you can leave the planning to the system and get back to your business.
Your demand planner
Every planWatches every SKU's trajectory and keeps its forecast current as new sales land — the same trend-aware statistical forecasting enterprise demand teams rely on.
Your supply planner
Every planTurns the forecast into a buying plan you can act on — what to order, how much, and when — with lead times, safety stock, and urgency handled for you.
Your analytics team
Every planFlags what deserves attention — cash tied up, quiet decliners, stockout risk — and answers plain-English questions with your store's actual numbers.
"What should I reorder before Black Friday?" · "Where is my cash tied up?"
The monthly planning cycle, run for you
Pro planFor larger merchants: the full Integrated Business Planning routine that Fortune 500 operators run — generated automatically every month, so you walk into the planning meeting with the story already written.
- Demand review — what changed in your forecast, and why
- Supply review — where the plan is at risk and what to adjust
- Executive summary — the month's decisions on one page
Built for busy merchants, not full-time planners
Alerts + weekly digest
A plain-English email every week: "here's what to reorder." Push, not just pull — you don't have to remember to log in.
Inline editing
Tweak order quantities and dates right in the table. Your judgment plus our math — no re-exporting to a spreadsheet.
CSV export
Export the buying plan for your purchasing team or your supplier in one click.
Lead-time aware
Reorder points account for supplier lead times and safety stock — so "order by" dates are dates you can actually hit.
Dead-stock flags
Slow movers are surfaced with the dollar value they're tying up, so you can mark down or discontinue with confidence.
26-week outlook
Forward demand per SKU, grouped by week — plan seasonal buys and cash flow half a year out.

Questions merchants ask us
How long does setup take?
Under 5 minutes. Install the app, approve the Shopify connection, and the 3-step wizard syncs your history and generates your first forecasts automatically.
How much of this is actually automated?
The whole planning chain. Supplana re-forecasts every SKU as new sales come in, rebuilds your supply plan from the forecast, and re-projects your inventory spend — automatically. Your job is to review, tweak anything you know better than the model, and approve.
How is this different from a moving average or a spreadsheet?
Supplana uses Holt's Linear Exponential Smoothing — a trend-aware model. Growing SKUs get growing forecasts and declining SKUs get declining ones, each with a 95% confidence band. And we always show the model's work: your actual history plotted against the forecast line.
I'm on Stocky. What happens when it shuts down?
Stocky is retired on August 31, 2026. Because Supplana syncs directly from Shopify, there's no data migration to do — install, connect, and your history is already there. See the full Stocky migration guide.
Can I adjust the recommendations?
Yes — that's the point. Edit order quantities and dates inline, and add demand overrides for promos or events the model can't know about. The plan recalculates instantly.
What does the free trial include?
Everything in the plan you pick — Starter, Growth, or Pro — free for 14 days, billed through Shopify afterward, cancel anytime. Choose Pro if you want to try the AI-run monthly planning cycle.
Want us to run it for you?
For larger or higher-touch merchants, our fractional inventory planner service handles it end to end: a weekly purchase plan, PO recommendations, quarterly planning, and Slack/email access to a senior planner with Fortune 500 supply-chain experience — app included.
