MRP One

Overview

MRP One brings material requirements, production planning, inventory, and shop-floor reporting into one cloud platform. It is most compelling for small and growing manufacturers that need those workflows together without installing or maintaining on-premises software. Its narrow free tier is useful for a small operation, but broader use starts at €115 per month.

Key features

The MRP engine calculates purchasing requirements using bills of materials, sales orders, inventory levels, and supplier lead times. That connects purchasing to demand and available stock, a practical advantage for teams trying to avoid buying materials without accounting for what they already hold. AI-assisted demand forecasting and planning suggestions add guidance, while production planning offers automatic and manual scheduling, visual Gantt charts, conflict detection, and capacity alerts. The mix can help teams spot scheduling pressure without giving up manual control.

Inventory management tracks real-time stock and reservations, allocates materials automatically, flags shortages, and records stock movements. Shop-floor workers can report labor, machine time, scrap, and quality data using barcode scanning or touchscreen input. Keeping these records alongside planning and inventory should suit manufacturers who want operational data tied to production activity rather than captured in a separate workflow.

MRP One is 100% cloud-based, with no installation, maintenance, or on-premises deployment. The company says most customers run their first MRP calculation within a week and that setup is designed not to require consultants or IT projects. It also says data is encrypted in transit and at rest, hosted on secure cloud infrastructure, and not shared with third parties.

Pricing

Free Forever: free, billed €0 forever. It allows 1 user, up to 12 workcenters, 15 workers, and 25 active orders, with a 1 GB database and daily archives retained for 7 days. Those hard caps make it a way to start or assess a very small operation, not a durable fit for a multi-user production team.

Small Teams: €115 a month, billed €115 per month. It supports up to 10 users and includes the full MRP II engine, production planning and scheduling, shop-floor reporting, inventory and materials management, order management, and email support. This is the entry point for teams that need the core workflow beyond the free plan’s single-user and order limits.

Growing Teams: €175 a month, billed €175 per month. The 50-user allowance is paired with resource and capacity management, advanced reporting and analytics, purchasing and supplier management, cost tracking per order, and priority support. It is the more suitable tier for manufacturers managing capacity and supplier decisions across a larger team; the extra spend buys capabilities beyond simply adding seats.

Enterprise: custom pricing, tailored to the customer. It includes unlimited users, custom API integrations, dedicated onboarding and training, an SLA guarantee, and dedicated support through an account manager. Enterprise is the clear fit when integrations or a service commitment matter, but its custom pricing means it cannot be compared against the fixed monthly tiers on price alone. Other plans can discuss integration needs with the company.

Platforms

MRP One runs on the web as a cloud service. It is a poor fit for organizations that require on-premises deployment.

Who it's for

The product names metalworking and fabrication, furniture and woodworking, electronics and assembly, textile and apparel, and custom manufacturing as target industries. Its combination of materials planning, capacity tools, and shop-floor capture is most relevant to manufacturers coordinating orders, resources, and inventory in one system. The free plan suits a single user testing a small workload; teams beyond those caps should budget for a paid plan.

Pros and cons

• Connected planning and operations: Material requirements, scheduling, stock management, and shop-floor reporting sit in the same platform.
• Useful scheduling controls: Gantt charts, conflict detection, capacity alerts, and manual as well as automatic scheduling support teams balancing visibility with direct oversight.
• Free tier has strict ceilings: One user and 25 active orders limit its usefulness for a working team.
• Enterprise integrations mean custom pricing: Organizations needing custom APIs must move beyond the fixed-price tiers and request tailored terms.
• Cloud-only deployment: There is no on-premises option for manufacturers that require local deployment.

Alternatives

Production Planning Software is a useful starting point for comparing products focused on planning. Adiasoft Production Software may suit a small operation that can work within its free allowance of two users, one branch, and 100 internal-control documents per month, but it does not include tax-valid invoicing on that plan. Odoo Manufacturing is worth considering if mobile access matters: it supports Android, iOS, and web, and its One App Free plan allows unlimited users.

Katana offers a permanent free tier with unlimited users and integrations, but caps it at 30 SKUs; it may fit a team whose catalog stays within that limit. For a broader platform comparison, abas ERP, Epicor Kinetic, NETVIBES, Interal Production, and PlanetTogether APS are alternatives to assess.

Verdict

MRP One is a strong fit for small and growing manufacturers that want materials, scheduling, inventory, and shop-floor reporting in one cloud system. Its strongest reason to choose it is the connection between those workflows, with paid plans adding meaningful capacity and purchasing tools as teams grow. Look elsewhere if a single-user free tier is too restrictive, on-premises deployment is essential, or you need to settle integration costs before engaging with a custom-priced Enterprise plan.
