Project ERP basics with cloud or on-prem deployment; project tools begin at Professional.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ArionERP connects project delivery with financial management for professional services, engineering and IT organizations. Its project capabilities cover job costing, budget-versus-actual tracking, resource scheduling, capacity planning, skills-based assignments, time and expense approvals, and client invoicing for fixed-price, time-and-materials, milestone and cost-plus work. Gantt charts, dependencies, milestones, Kanban boards, document version control and forecasting dashboards support day-to-day delivery, while general ledger and payables/receivables handle core finance. The broader suite adds CRM, sales, inventory, HR and manufacturing modules, making it relevant to small, mid-market and enterprise teams.
Published plans separate cloud subscriptions from on-premises licenses. Essential Cloud costs $300 per user per year and includes CRM, sales, purchasing, inventory, accounting, 5 GB storage per user and a 99.9% uptime SLA. Professional Cloud is $480 per user per year and adds Project Management, Helpdesk, HR, POS and a website/e-commerce builder. Enterprise Cloud costs $780 per user per year, adding manufacturing, quality, PLM, advanced BI and analytics, multi-company and API access. On-premises plans are $450, $720 and $1,170 per user for Essential, Professional and Enterprise, respectively, with perpetual licensing and annual software updates; the published model describes these as one-time licenses plus annual maintenance.
Deployment options include cloud and self-hosted environments, with web, iOS, Android and API access. Named integrations are Jira, Salesforce and GitHub, and the product lists SOC 2 and ISO 27001 compliance. Teams wanting project accounting, resource planning and billing alongside core ERP can start with Professional Cloud or Professional On-Premises, depending on control requirements. Organizations focused on specialized construction controls should compare alternatives before committing, and teams needing manufacturing, advanced analytics or multi-company operations should budget for Enterprise.
ArionERP pros and cons
- Where it wins
- Job costing, budgets, profitability, time, expenses and client billing
- Cloud or self-hosted deployment across web, iOS, Android and API
- Core finance plus CRM, inventory, HR and manufacturing modules
- Where it doesn't
- Project Management starts in Professional Cloud, not Essential
- Cloud plans bill annually per user, so costs scale with seats
- Manufacturing, BI, multi-company and API access require Enterprise
