E21 ERP review
A broad ERP for small manufacturers spanning process, discrete, and mixed-mode production.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
E21 ERP is an integrated business system for manufacturers and distributors, with a particular fit for small and mid-market organizations running process, discrete, or mixed-mode operations. Its scope includes manufacturing, planning, inventory, warehouse management, procurement, order management, finance, CRM, business intelligence, e-commerce, and EDI. Production teams get scheduling, reporting, bills of material, formulas, recipes, routings, and engineering change order management in the same system.
Pricing is handled through contact sales, with a published single per-concurrent-user monthly pricing model and no free plan. Deployment can be cloud-based or self-hosted, giving organizations a choice between hosted infrastructure and managing their own environment. The product also provides web access plus iOS and Android apps. Mobile functions include contact and task management, inventory lookup, reporting, and expense submission, which can support teams working away from a primary workstation.
Manufacturing depth is a central strength. E21 covers make-to-stock, make-to-order, assemble-to-order, configure-to-order, and repetitive production alongside process, discrete, and mixed-mode workflows. Quality features include holds, releases, and customer-specific requirements, while lot tracking, traceability, and recall management address products that require controlled histories. Buyers wanting one system across production, inventory, procurement, CRM, and related business functions should consider E21 ERP. Companies seeking a narrowly focused manufacturing tool, or support options beyond phone service, may prefer a more specialized alternative.
