How to Evaluate MRP Software: A Practical Framework
Step 1: Define Your Requirements
Before contacting vendors, document your specific needs:
- How many active BOMs do you manage?
- What is your production model? (Make-to-order, make-to-stock, engineer-to-order, mixed)
- How many work centers or machines do you schedule across?
- What existing systems must the MRP tool integrate with?
- What is your biggest current pain? (Material shortages, late deliveries, capacity bottlenecks, inventory excess)
Step 2: Calculate Total Cost of Ownership
Do not compare sticker prices. Compare 5-year total cost of ownership:
| Cost Component | Subscription Model (Example) | One-Time License (Example) |
|---|---|---|
| Year 1 license/subscription | $12,000 ($100/user/mo x 10 users) | $25,000 one-time |
| Year 1 implementation | $5,000 | $5,000 |
| Years 2-5 subscription | $48,000 ($12,000/yr x 4) | $0 |
| Years 2-5 maintenance | Included | $5,000 ($1,250/yr) |
| 5-Year Total | $65,000 | $35,000 |
The one-time license model, which RMDB uses, often delivers significantly lower total cost, especially as you add users over time.
Step 3: Test with Your Actual Data
Never buy MRP software based on a demo with sample data. Provide vendors with your actual BOMs, inventory data, and a realistic set of production orders. Watch how the system handles your complexity, not a simplified demonstration.
Step 4: Evaluate Implementation Support
Ask specific questions about implementation:
- Who does the data migration?
- How much training is included?
- What happens if we need help after go-live?
- What is the typical time from purchase to productive use?
Refer to our MRP implementation checklist for a complete list of evaluation criteria and go-live requirements.
Step 5: Check References in Your Industry
Ask for references from manufacturers similar to your size, industry, and production model. A tool that works brilliantly for a consumer goods batch manufacturer may struggle in a high-mix job shop.
Common Mistakes in MRP Software Selection
Based on 35 years of experience helping manufacturers choose and implement planning tools, these are the most frequent selection mistakes:
1. Buying for features you will never use. Enterprise ERP modules bundled with MRP sound impressive but add cost and complexity without value for small operations.
2. Ignoring data readiness. No MRP software can compensate for inaccurate BOMs or unreliable inventory counts. Budget time and resources for data preparation.
3. Choosing based on price alone. The cheapest option may lack critical features like finite capacity scheduling or multi-level BOM support that you will need as you grow.
4. Not involving shop floor users. Planners and shop floor supervisors must find the tool usable. Include them in the evaluation process.
5. Underestimating the spreadsheet to MRP transition. Moving from Excel to MRP requires process changes, not just new software. Plan for change management.
Our Recommendation
For small to mid-size manufacturers, especially job shops and make-to-order operations, we recommend evaluating RMDB from User Solutions alongside one or two cloud-based alternatives. RMDB's combination of finite capacity scheduling, material planning, visual Gantt charts, and one-time licensing delivers the best value for manufacturers whose primary challenge is production planning.
If you need a light all-in-one system that includes CRM and basic accounting, a cloud MRP tool may suit your needs. But if your pain is scheduling, capacity planning, and material management, a purpose-built tool will deliver significantly better results.
Frequently Asked Questions
The best MRP software depends on your specific needs. RMDB by User Solutions is ideal for shops that need finite capacity scheduling with material planning and prefer a one-time license. MRPeasy suits basic cloud MRP needs. Katana is strong for small batch manufacturers. The key is matching the tool to your production complexity and budget.
MRP software for small manufacturers ranges from $49-199 per user per month for cloud subscriptions to one-time license fees of $5,000-$50,000 for on-premise solutions. Over 5 years, subscription costs typically exceed one-time license costs. Factor in implementation, training, and data migration costs as well.
Yes. Many small manufacturers use standalone MRP and scheduling software alongside basic accounting software like QuickBooks. You do not need full ERP to benefit from MRP. Tools like RMDB are designed to work independently or integrate with existing systems.
Implementation timelines vary significantly. Cloud MRP tools can be set up in 1-4 weeks. RMDB from User Solutions implements in as few as 5 days. Full ERP systems with MRP modules typically take 6-18 months. The biggest variable is data preparation, not the software itself.
Prioritize BOM management, inventory tracking, purchase order generation, and production scheduling. For job shops and make-to-order operations, also look for finite capacity scheduling, visual Gantt charts, and what-if scenario planning. Avoid paying for enterprise features like multi-currency or global supply chain management that you will not use.

Expert Q&A: Deep Dive
Q: After 35 years of working with small manufacturers, what is the biggest mistake you see in MRP software selection?
A: The biggest mistake is buying more system than you need. Small manufacturers get sold on full ERP systems with MRP modules by enterprise software sales teams who convince them they need everything. Six months and $200,000 later, they are using maybe 20% of the system and struggling with the complexity. A focused MRP and scheduling tool that solves your specific production planning problems will deliver faster ROI. You can always expand later. We built RMDB specifically because we saw this pattern repeatedly: manufacturers drowning in software they did not need when what they actually needed was a practical scheduling and material planning tool.
Q: What should a small manufacturer have in place before evaluating MRP software?
A: Before you even look at software, make sure you have three things: accurate bills of materials for your top products, a reliable inventory count system, and documented routings with realistic time estimates. If these do not exist, no MRP software will save you. We have had prospects come to us wanting to implement RMDB but their BOMs were in the owner's head and inventory was tracked on sticky notes. We always recommend investing 2-4 weeks in data preparation before software evaluation. That effort pays dividends regardless of which tool you choose.
Q: How do you see cloud versus on-premise MRP evolving for small manufacturers?
A: Cloud MRP has become the default for new implementations, and for good reason. Lower upfront cost, automatic updates, and access from anywhere are real advantages. But there are trade-offs small manufacturers should consider. Cloud subscriptions add up over time and can exceed on-premise costs within 3-5 years. You are also dependent on internet connectivity and the vendor's continued existence. We offer both options with RMDB because we believe manufacturers should choose what fits their situation. Some of our customers in defense manufacturing or remote locations prefer on-premise for security and reliability. Others love the cloud flexibility. The right answer depends on your specific constraints.
