The framework
One platform. Every stage of the loop.
Unlike bolt-on tools, Sellcast is one system built to run the whole cycle (forecast, buy, promote, and liquidate) on your live Shopify data, with you approving every move.
Promos scored before you hit send.
Every promo scored 0–100 on lift vs. margin, joined to the stock it actually moves.
Markdowns that cannot go below your floor.
Liquidation gated by real per-unit economics, never a discount below your floor.
Leave Stocky before it leaves you.
Move suppliers, per-SKU costs, and open POs before Stocky shuts down Aug 31.

Know what to buy before the stockout
Restocking on time is half the battle, and it starts with a forecast you can trust. Sellcast pulls sales, inventory, suppliers, costs, and promo performance into one model, then shows its work for every SKU.
- Every forecast decomposes into base, trend, seasonality, and event lifts, with anomalies excluded and shown.
- A plan-vs-actual board that replans as sales land, with lockable closed periods.
- A simulator for what-if calls before you commit cash.
Forecast · HTX-41
SampleBuying without the Sunday-night spreadsheet
The forecast decides the buy. Sellcast ranks every SKU by revenue at risk and drafts the POs inside the authority limits you set. One SKU, followed all the way from signal to purchase order.
- A buying table sorted by revenue at risk: stockout, at-risk, healthy, overstock, at SKU level.
- PO drafts created inside authority limits you set. Nothing is sent without your sign-off.
- Suppliers, lead times, transfers, and movements in the same loop.
Portfolio health · 304 SKUs
SampleRevenue at risk $128K across all 304 flagged SKUs (at-risk + stockout).
Every promo scored 0–100 on lift vs. margin
Demand Pulse joins live inventory to real discount-code performance, so the campaign calendar knows what you can fulfill and what's gathering dust, before you hit send.
- Promote winners, protect scarce stock, liquidate dead weight. One board.
- A promo ledger that scores every code on lift versus margin.
- Recommendations that update as sales and forecasts land.
Promo score · SUMMER-15
SampleZero markdowns below your margin floor
When stock won't move, Sellcast gates a markdown against your real unit economics (the full cost stack) and shows the per-unit P&L before you run it.
- Gates open only when your rules are met.
- Markdown depth computed from COGS, fees, shipping, returns, and overhead.
- Per-unit recovery shown before you commit.
Per-unit economics at −30%

What we believe
Opinionated, on purpose
Sellcast is pre-launch and onboarding design partners. Here's the thinking the product is built on.
Explainable forecasting
If a forecast can't show its work, you shouldn't have to trust it. Every number opens to its base, trend, seasonality, and the events behind it.
base · trend · seasonality · events
Draft-and-approve
The agent drafts; you approve. Nothing reaches your suppliers or your storefront without a human saying yes.
Margin-floor liquidation
A markdown below your true unit cost isn't a clearance. It's a loss. Sellcast will never recommend one.
0 markdowns below your floor
Inventory-aware marketing
Your stock position should drive your marketing calendar: promote what you can fulfill, protect what's scarce, liquidate what won't move.

FAQ
The questions worth asking
Will Sellcast work for my store?
Sellcast is made for Shopify brands with real SKU depth. If you're juggling reorders, promos, and overstock across more than a handful of products, it fits. Forecast quality improves with sales history; six months or more is ideal.
How long does setup take?
Connecting Shopify takes minutes. Sellcast then backfills your sales and inventory history and builds your first forecasts. You review your first plan rather than configure one.
Where does the data come from, and who sees it?
Your Shopify store (and optionally Brightpearl or CSV imports). Your data is never sold and never used to train shared models. See the privacy policy for specifics.
How do the forecasts actually work?
Each forecast decomposes into base rate, trend, seasonality, and event lifts, with excluded anomalies listed. You can open any number and see exactly how it was built, and override it.
Do you support multiple locations and warehouses?
Yes. Locations, transfers, movements, and a network view are part of the supply loop, and the buying table respects per-location stock.
Can I migrate from Stocky or spreadsheets?
Yes. There's a guided Stocky migration wizard, and CSV import covers suppliers, per-SKU costs, lead times, open POs, and your inventory baseline. Per Shopify's announcement, Stocky stops working August 31, 2026.
What does the “agent” actually do?
It drafts purchase orders inside authority limits you set, and recommends the transfers, promos, and markdowns to review — each with citations to the data behind it. Every action waits in your inbox for your approval; nothing executes on its own.
