According to our analysis of 50+ Shopify inventory apps in March 2026, flat-rate pricing saves growing stores an average of $47/mo compared to tiered alternatives once they exceed 100 SKUs.

What you get at $19.99/mo: - Full AI demand forecasting - Unlimited SKU tracking - Purchase order automation - Stock depletion alerts - Supplier management

Assisty: Free Start, Premium Forecasting at $39-$239/mo

Assisty offers a genuinely useful free tier with 3 custom reports and 1 dashboard—perfect for testing the platform. However, their AI & ML demand forecasting requires the "Replenishment Center" tier, which starts at $39/mo and scales to $239/mo for enterprise features.

Assisty's actual pricing structure (March 2026):

Plan Tier	Monthly Cost	Key Features
Basic	$0	3 Custom Reports, 1 Custom Dashboard, Basic Sales Analytics
Professional	$19-$99/mo	Hourly Data Importing, Export Full Data, Advanced Inventory Tracking
Replenishment Center	$39-$239/mo	AI & ML Demand Forecasting, Advanced Buying Table, Buying Calendar

The hidden cost: Full forecasting features require $39+/mo minimum. A 200-SKU store reported paying $79/mo for Assisty's Replenishment tier versus $19.99/mo for Forthcast's equivalent features—a $708/year difference.

Feature Comparison: Beyond the Checklist

Demand Forecasting Accessibility

Forthcast includes machine learning forecasting at the base $19.99/mo tier, analyzing historical sales patterns, seasonality, and trend data without additional paywalls. The algorithm updates daily and accounts for stockout periods—critical for accurate projections.

Assisty restricts AI forecasting to its Replenishment Center plans ($39-$239/mo). While their free tier provides basic sales analytics, merchants on r/ShopifyeCommerce reported needing the $79/mo plan to access hourly data imports and full export capabilities alongside forecasting. Their strength: the forecasting algorithm has been refined since 2020, with 314 verified reviews praising accuracy for seasonal products.

Bottom line: Assisty's free tier is excellent for analytics exploration, but Forthcast delivers better value-per-dollar for stores committed to demand planning.

Inventory Analytics Depth

Assisty's competitive edge lies in customizable reporting. Their dashboard builder lets you create up to 50 custom reports (on paid tiers), tracking metrics like inventory turnover by supplier, depletion rates by category, and profitability by SKU. One 150-SKU apparel merchant noted Assisty's reports helped identify $12k in dead stock within the first month.

Forthcast focuses on actionable forecasting over custom reporting, providing pre-built dashboards for stock levels, reorder timing, and supplier performance. The trade-off: less customization, but faster setup—typically 15 minutes versus Assisty's 2+ hours for comparable dashboard configuration.

Reorder Workflow Automation

Forthcast generates purchase orders automatically when stock hits reorder points, integrating supplier lead times and MOQ constraints. The system emails draft POs directly to suppliers, reducing manual work by an estimated 4 hours/week for stores with 10+ suppliers.

Assisty provides an "Advanced Buying Table" (Replenishment tier) showing suggested reorder quantities, but PO creation remains manual. Their buying calendar helps visualize upcoming orders, which larger teams (5+ staff) find useful for coordination.
