Forthcast is inventory management and demand forecasting software for Shopify. It predicts how much of each SKU you'll sell over the next one to twelve months, then turns that into automated purchase orders, replenishment schedules, and stockout alerts — so you reorder the right quantity before you run out or overbuy. It's $19.99/month flat for unlimited SKUs, with no per-SKU fees and a 14-day free trial.
From connected store to drafted POs in three steps
No spreadsheets, no manual demand math. Forthcast turns your Shopify history into ranked, ready-to-send replenishment.
Connect Shopify
Install in one click and Forthcast securely reads your full sales history. You're live in under ten minutes — nothing to configure.
Forecast every SKU ~a year ahead
Forthcast models demand for each SKU — seasonality, trend and velocity — forecasting around 12 months ahead and beyond as your history grows.
Ranked reorders + auto-drafted POs
The moment a SKU dips below its reorder point, it's ranked by revenue impact and a purchase order is drafted. You review and send — nothing orders itself.
Everything you need to keep inventory in balance
Built for Shopify merchants who want forecasting and replenishment to run themselves — without a planner or a per-SKU bill.
AI demand forecasting
Every SKU forecast from your own sales history — capturing seasonality, trend and velocity around a year ahead and beyond.
Automated purchase orders
Forthcast drafts each PO with the right quantity and timing. You review and send — nothing is ordered without you.
Reorder-point alerts
Get flagged the moment any SKU dips below its reorder point — ranked by revenue impact so the urgent ones surface first.
Safety-stock optimization
Right-size buffers per SKU against demand variability and lead times — enough to avoid stockouts, not enough to tie up cash.
Multi-location stock
See stock and demand across your Shopify locations, so reorder decisions reflect where inventory actually sits.
Seasonality & BFCM
Forecasts learn your seasonal peaks and ramp orders ahead of Black Friday / Cyber Monday — so you stock the surge, not the regret.

Stands out for the reorder cycle
“We’ve tested several Shopify apps to improve our repeat purchase flow, but this one stands out because of how well the reorder cycle is actually implemented.”
Great Stocky alternative
“So far so good! It looks like this app will do more than Shopify’s Stocky and will do it better. The support has been amazing. Very responsive and interested in what we need.”
One flat price. Any catalog size.
Most forecasting tools charge per SKU, per order line, or by usage tier — so the bigger you grow, the more you pay to plan. Forthcast doesn't.
Tiered seat counts, per-SKU add-ons and usage overages — the cost of planning climbs exactly as your catalog does.
- Per-SKU fees that punish a growing catalog
- Usage tiers and overage surprises
- Bills that get unpredictable at scale
One flat price for your whole catalog — forecasting and auto-drafted POs for every SKU, no per-SKU fees, no usage tiers.
- Flat $19.99/month at any catalog size
- No per-SKU fees, no usage tiers
