MRP One

Overview

MRP One is a web-based manufacturing resource planning system for teams coordinating materials, production, and shop-floor work. It suits manufacturers that want those workflows in a cloud service rather than an on-premises deployment. Its main appeal is the connection between material requirements, scheduling, inventory, and production reporting; the free plan is tightly capped, and fuller capacity starts at €115 per month.

Key features

The MRP engine calculates purchasing requirements using bills of materials, sales orders, inventory, and supplier lead times. That gives purchasing decisions context from both demand and existing stock. AI-assisted demand forecasting and planning suggestions add another planning input, while automatic or manual scheduling lets teams choose between automated plans and direct control.

Scheduling includes visual Gantt charts, conflict detection, and capacity alerts. These tools make clashes and constrained resources visible, but the ability to plan around them matters most to teams with active production schedules. Inventory management tracks stock and reservations in real time, allocates materials automatically, flags shortages, and records stock movements.

For shop-floor reporting, workers can use barcode scanning or touchscreen input to record labor, machine time, scrap, and quality data. Bringing those records into the same platform as materials and planning can suit manufacturers who want operational reporting alongside production control. MRP One targets metalworking and fabrication, furniture and woodworking, electronics and assembly, textile and apparel, and custom manufacturing.

The product is fully 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 costs €0 forever and allows one user, up to 12 workcenters, 15 workers, and 25 active orders, with a 1 GB database and daily archives retained for seven days. That is a useful constrained starting point, but the user and order caps make it a poor fit for a larger or busier operation.

Small Teams costs €115 per month for up to 10 users. It 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 paid plan for teams that need the connected core workflows without the broader resource, purchasing, and analytics tools in the next tier.

Growing Teams costs €175 per month for up to 50 users. It adds resource and capacity management, advanced reporting and analytics, purchasing and supplier management, cost tracking per order, and priority support. The higher price buys both more user room and controls for teams managing capacity, suppliers, and order costs; smaller teams that do not need those additions may find Small Teams sufficient.

Enterprise has custom pricing and unlimited users. It includes custom API integrations, dedicated onboarding and training, an SLA guarantee, and a dedicated account manager. This tier is aimed at organizations needing those integration and service commitments rather than a published fixed monthly rate. Enterprise includes custom API integrations; other plans can discuss integration needs with the company. Support rises from email on Small Teams to priority support on Growing Teams and dedicated account-manager support on Enterprise.

Platforms

MRP One runs on the web and is deployed in the cloud. There is no on-premises option, so it is not the choice for manufacturers that require local deployment.

Who it's for

MRP One is strongest for small and growing manufacturers that want requirements planning, scheduling, stock control, and shop-floor data in one cloud system. Its industry focus spans fabrication, woodworking, electronics, textiles, and custom manufacturing. The free plan can establish whether the workflow fits a very small operation; teams exceeding its single-user or 25-active-order limits will need a paid plan. Manufacturers that need more than 50 users, custom API integrations, or dedicated onboarding can consider Enterprise.

Pros and cons

• Pros: The MRP engine uses orders, bills of materials, inventory, and supplier lead times together, tying purchasing needs to demand and stock.
• Pros: Scheduling offers both automatic and manual planning, with Gantt charts, conflict detection, and capacity alerts for teams balancing competing work.
• Pros: Barcode and touchscreen reporting covers labor, machine time, scrap, and quality, while inventory tools add reservations, allocations, shortage alerts, and movement history.
• Cons: Free Forever is limited to one user and 25 active orders, so it is a narrow fit for production teams rather than a broad free deployment.
• Cons: Small Teams stops at 10 users and lacks the resource and capacity management, advanced analytics, supplier management, and order cost tracking added at €175 per month.
• Cons: MRP One is cloud-only, excluding manufacturers that need an on-premises system.

Alternatives

Production Planning Software is a category directory for comparing production-planning options. Adiasoft Production Software is worth considering if its free offer of up to 100 internal-control documents per month, one branch, and two users fits better; its free plan has no card, term, or commitment, but does not provide tax-valid invoicing.

abas ERP is another paid option, with platforms including web, mobile, desktop, Linux, API, and self-hosted deployment; choose it for those platform choices, while its implementation costs vary with users, process complexity, migration, functions, and adjustments. Epicor Kinetic is a paid alternative with cloud packages, platform-core selection, concurrent user licenses, and industry bundles.

Katana may suit a team prioritizing a free inventory tier: its free plan allows 30 SKUs, unlimited users, integrations, and inventory locations, with no card or expiry date. NETVIBES is another paid option. Odoo Manufacturing offers a free One App plan with unlimited users, while its Standard and Custom plans are also listed as options.

Monitor ERP System is a paid alternative with a cloud plan at €93 per user per month for a complete ERP solution; compare it if that per-user pricing and broader ERP framing better suit the operation. Acumatica Field Service is another paid option with custom pricing based on applications, expected usage and resources, and deployment preferences.

Verdict

Choose MRP One if a small or growing manufacturer wants materials planning, production scheduling, inventory, and shop-floor reporting connected in a cloud system. The strongest reason to choose it is that these workflows share one planning and operating context, with the Growing Teams tier extending that setup to capacity and supplier management. Look elsewhere if a single-user, 25-order free ceiling is too restrictive, if on-premises deployment is essential, or if your team needs more than 50 users without custom pricing.
