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.
STEP 01
Connect Shopify
Connect the Shopify store so Forthcast can read its sales history and begin modelling demand from the merchant's own data.
STEP 02
Forecast demand up to 12 months ahead
Forthcast models demand for eligible products with sales history and active inventory, up to about 12 months ahead. New products use separate seed forecasts.
STEP 03
Ranked reorders + auto-drafted POs
Review products below their reorder points, prioritize stockout risk, and create draft purchase orders. You review quantities and send.
Everything you need to keep inventory in balance
Built for Shopify merchants who want clearer forecasting and merchant-controlled replenishment without a per-SKU bill.
AI demand forecasting
Eligible products are modelled from your own sales history, capturing seasonality, trend and velocity up to about 12 months ahead.
Draft purchase orders
Forthcast helps you draft POs with suggested quantities. You review and send — nothing is ordered without you.
Reorder-point alerts
Review products below their reorder points and use revenue-at-risk estimates to prioritize your next order.
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 views
See inventory by location, so reorder decisions reflect where stock actually sits. Demand forecasts and reorder points remain store-wide.
Seasonality & BFCM
Use seasonal demand patterns to review your replenishment plan ahead of Black Friday, Cyber Monday and other peaks.

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.”

Questions, answered
What is Forthcast and how does it manage Shopify inventory?
Forthcast is demand forecasting and inventory planning software for Shopify. It produces store-wide forecasts and reorder points up to about 12 months ahead, ranks stockout risk, and creates draft purchase orders that you review before sending. It costs $19.99 per month flat, with no SKU tiers or per-SKU fees, and a 14-day trial billed through Shopify. Forecast coverage depends on sales history and active inventory; new products use separate seed forecasts.
What inventory signals does Forthcast use?
Forthcast models eligible products from the merchant's Shopify sales history, seasonality, trend, and velocity. Forecast eligibility depends on sales history and active inventory; new products use separate seed forecasts. It also learns each supplier's actual lead time over time, and Judge.me reviews can be synced through the documented API-token integration.
How much does Forthcast cost?
Forthcast's Basic Plan costs $19.99 per month through Shopify, with no SKU tiers or per-SKU fees. Flat billing is separate from forecast coverage. The main forecast set depends on sales history and active inventory, while new products can use seed forecasts. Stock can be viewed by location, but demand forecasts and reorder points are store-wide. A full rebuild with no selected SKUs has a 300-SKU processing limit; selected incremental updates can cover more.
Does Forthcast place purchase orders automatically?
No. Forthcast calculates reorder timing and quantity and drafts a purchase order for the merchant to review and send; it does not place, send, or submit an order automatically.
Can I evaluate Forthcast as a Stocky replacement?
Yes, if your required workflow is store-wide demand forecasting, smart reorder alerts, safety-stock planning, and draft purchase orders. Check your exact Stocky workflow against Forthcast's documented features before migrating; this page does not claim feature-for-feature parity.
