Forthcast: Built for Shopify Merchants Who Are Done Guessing

We believe every merchant deserves accurate demand forecasting, not just enterprise brands with $50k/year budgets.

Why We Built Forthcast

Inventory forecasting tools were built for large enterprises, not independent Shopify merchants. The incumbents charge per-SKU fees that make them unaffordable for growing stores, and they hide their best features behind enterprise plans.

We built Forthcast to give every Shopify merchant access to the same machine learning demand forecasting that large brands use — at a flat $19.99/month with no SKU limits.

Our Approach

Forthcast connects directly to your Shopify store and learns from your actual order history. The longer you use it, the more accurate your forecasts become.

The base plan includes store-wide forecasting, draft purchase orders for merchant review, ABC analysis, and multi-location stock views.

Part of the Forthsuite Family

Forthcast is one of five Forth supply-chain products. Forthroute covers Shopify returns, Forthmatch monitors an existing 3PL, Forthclear is a standalone surplus marketplace, and Forthsource verifies suppliers for importers and sourcing teams.

Recognition

Forthcast was named Best eCommerce Inventory Forecasting App 2026 in Corporate Vision's Logistics, Warehouse and Supply Chain Awards.
