The platform
One loop, from forecast to markdown.
Sellcast runs forecasting, buying, promotion, and liquidation as a single AI agent on your live Shopify data. Each stage feeds the next, and nothing executes until you approve it.
Your systems
One AI loop
Decisions, back to you
- PO drafted→ Brightpearl
- Promo scored→ you run in Shopify
- Markdown gatedat your margin floor
- Forecast refreshed+ cash-flow
- Stockout alert12 days of cover
Restocking on time is half the job.
Every tool in this category helps you buy right. Almost none of them help you sell through what you bought.
One loop, and a Copilot that drafts it
Forecast demand, and show the drivers behind the number
Draft the PO before the tote runs out
Draft the promo, and price it against what you actually hold
Draft the markdown on what did not sell
Read your live Shopify and Brightpearl data, not last quarter's export
You approve every action.
01 · Forecast
Know what to buy before the stockout
- 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.

02 · Buy
Buying without the Sunday-night spreadsheet
- 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.

03 · Promote
Promote what you actually have, not what you wish you had
- Demand Pulse: what to promote, protect, and liquidate, joined to live inventory and real discount-code performance.
- A promo ledger that records every code's discount, lift, and return rate, so the next promo learns from the last.
- A campaign calendar that knows your days of cover before you hit send.

04 · Liquidate
Clear dead stock without eating the margin twice
- Liquidation gates that open only when your rules are met.
- Markdown depth computed from your full cost stack, never below the margin floor you set.
- Per-unit liquidation P&L, so you see the recovery before you run it.
Liquidate, HTX-41
210d coverUnit economics at −30%
Gated by your full cost stack ($17.60/unit). The gate holds the moment a discount would sell below cost.
Explainable AI
AI that shows its work
Sellcast's AI is built to be checked. Every forecast has receipts, and every action the agent takes waits for your approval.
Grounded
Recommendations come from your sales, inventory, and promo history, with citations back to the data.
Human-approved
The agent drafts purchase orders inside authority limits, and recommends the transfers, promos, and markdowns to review. You approve every action; nothing executes on its own.
Private
Your data is never sold and never used to train shared models.
