Inventory management software pricing comparison: what each tier costs

Here is the inventory management software pricing comparison in one view, by tier. The category splits into three price bands in 2026:

• Flat-rate (one price, any catalog) — Forthcast at a flat $19.99/month with no per-SKU and no per-user fees, plus a 14-day free trial. Best when you want a predictable bill that doesn't climb as your SKU count or order volume grows.
• Entry-level tiered — typically $50–$300/month, with pricing that scales by SKU count, order volume, or feature tier. Tools in this band include Prediko (from $49/month) and Fabrikatör (from $99/month). Good for merchants who want add-on modules and accept a bill that grows with usage.
• Midmarket / quote-based — roughly $1,500–$5,000/month, often quote-only with no published price. Inventory Planner is quote-based with no public pricing. Aimed at larger multi-channel operations with procurement and onboarding budgets.

The practical read: if you're a Shopify merchant who wants forecasting and reorder alerts without a usage-scaled bill, a flat-rate tool is the lowest-friction starting point; move up a band only when you genuinely need the extra modules or seats. For most stores, the deciding factor isn't the headline price but whether the bill stays flat as the catalog grows.

Inventory management software pricing tiers: how they're structured

Inventory management software pricing tiers are structured around what scales the bill, and that's the number to check before the headline price. The four common tier models:

1. Flat-rate — one fixed monthly price regardless of SKU count, users, or order volume (for example, Forthcast at $19.99/month). The bill is the same in month one and at 10× the catalog.
2. Per-SKU / per-order tiers — the price steps up as you cross SKU or order-volume thresholds. Predictable only if your catalog and volume are stable.
3. Per-seat tiers — priced by the number of users, common in tools built for multi-person ops teams.
4. Quote-based / enterprise — no published tier; pricing is negotiated (for example, Inventory Planner is quote-based). Expect onboarding fees and annual commitments.

When you compare pricing tiers, normalise to your SKU count and order volume 12 months out, not today's — a tool that looks cheap at the entry tier can cross into a higher band as you grow. A flat-rate tier removes that variable entirely: the same $19.99/month at any catalog size. Forthcast applies this flat model to SKU-level demand forecasts and automated reorder alerts for Shopify, so the price doesn't change as you add products.

Which inventory management software pricing fits your store?

Match the pricing model to your stage rather than chasing the lowest sticker:

• Solo or small Shopify store, predictable budget — a flat-rate tool such as Forthcast ($19.99/month, 14-day trial) gives forecasting and reorder alerts without a bill that scales by SKU or seat.
• Growing store that wants add-on modules — an entry-tiered tool ($50–$300/month, e.g. Prediko from $49/month or Fabrikatör from $99/month) adds features but the cost rises with usage.
• Large multi-channel operation with a procurement process — a quote-based / midmarket platform ($1,500–$5,000/month, e.g. Inventory Planner) fits if you need enterprise onboarding and custom integrations.

For a Shopify merchant who mainly needs accurate SKU-level demand forecasts and automated reorder alerts — and wants the bill to stay flat as the catalog grows — Forthcast is built for exactly that at a flat $19.99/month, at any SKU range. You can start a 14-day trial from the Forthcast listing on the Shopify App Store and compare it against your current spreadsheet or usage-scaled tool before committing.
