ERP Requirements: The Complete Guide & Checklist (2026)

What Are ERP Requirements?

ERP requirements are the functional and technical specifications that define what your enterprise resource planning system must do to support your business processes. A well-defined requirements list ensures you select an ERP that fits your operations, industry, and growth trajectory — rather than adapting your business to fit the software.

Requirements typically fall into three categories:

• Functional requirements — the modules and features your ERP must include (finance, procurement, manufacturing, etc.)
• Technical requirements — deployment model, integration capabilities, security standards, and scalability
• Non-functional requirements — usability, vendor support, implementation timeline, and total cost of ownership

Build your requirements list interactively — Our ERP Requirements Wizard walks you through an 8-step process covering industry, company size, modules, and 500+ individual requirements. Start the Wizard →

The 13 Core ERP Requirement Areas

Every ERP evaluation should assess requirements across these functional modules. The importance of each depends on your industry, size, and operational complexity.

1. Finance

General ledger, accounts payable/receivable, budgeting, financial consolidation, tax management, and regulatory compliance. Finance is the backbone of every ERP system. View all Finance requirements →

3. Sales

Quotes, sales orders, pricing management, CRM integration, and sales analytics. Essential for revenue-generating operations. View all Sales requirements →

ERP Requirements by Company Size

Your company size significantly affects which requirements are most important:

Small Business (1–200 employees)

• Focus on core finance, sales, and inventory modules
• Prioritise ease of use and fast implementation
• Cloud deployment preferred for lower upfront costs
• Typical budget: $50K–$250K total cost of ownership (Year 1)

Mid-Market (201–1,000 employees)

• All core modules plus industry-specific requirements
• Multi-entity and multi-currency support becomes critical
• Integration with existing line-of-business applications
• Advanced reporting and analytics requirements
• Typical budget: $250K–$1M+ total cost of ownership (Year 1)

Enterprise (1,000+ employees)

• Full module coverage with deep configurability
• Global requirements: multi-language, multi-GAAP, country-specific localizations
• Complex workflows, approval chains, and segregation of duties
• Advanced supply chain, manufacturing, and quality management
• Enterprise-grade security, compliance, and audit requirements
• Typical budget: $1M–$10M+ total cost of ownership (Year 1)

How to Gather ERP Requirements

Follow this 5-step process to build a comprehensive requirements document:

Step 1: Identify Stakeholders

Map every department that will use or be affected by the ERP system. Include finance, operations, IT, HR, sales, and executive leadership. Each stakeholder group brings different requirements.

Step 2: Document Current Processes

Before defining what you need, understand what you have. Map current workflows, pain points, and manual workarounds. This reveals both functional gaps and process improvement opportunities.

Step 3: Define Functional Requirements

Use our 13 module framework to systematically evaluate what features you need. For each module, classify requirements as:

• Must-have — essential for day-one operations
• Should-have — needed within the first year
• Nice-to-have — future phase considerations

Step 4: Specify Technical Requirements

Document your technical environment and constraints:

• Deployment preference (cloud, on-premise, hybrid)
• Integration requirements (CRM, e-commerce, payroll, BI tools)
• Data migration scope and complexity
• Security and compliance standards
• User count and concurrency requirements

Step 5: Prioritise and Score

Rank requirements by business impact and urgency. This becomes your evaluation scorecard when comparing ERP vendors. Our Requirements Wizard automates this process and generates a prioritised checklist.

Frequently Asked Questions

What should be included in an ERP requirements document?

An ERP requirements document should include functional requirements (the modules and features needed), technical requirements (deployment, integrations, security), non-functional requirements (performance, usability, support), and business context (industry, company size, budget, timeline). Our framework covers 13 functional modules with over 500 individual requirements.

How many requirements should an ERP RFP include?

A typical ERP RFP includes 150–400 requirements depending on the scope of the project. Small businesses may focus on 100–150 core requirements across finance, sales, and inventory. Mid-market companies typically need 200–350 requirements. Enterprise organisations often exceed 400 requirements across all modules.

What is the difference between functional and non-functional ERP requirements?

Functional requirements define what the system must do — specific features like invoice processing, production scheduling, or payroll calculation. Non-functional requirements define how the system must perform — including response time, uptime SLAs, data security standards, user experience, and vendor support quality.

How long does ERP requirements gathering take?

Requirements gathering typically takes 4–8 weeks for mid-market companies. Large enterprises may need 8–16 weeks. Our ERP Requirements Wizard accelerates this process by providing a pre-built framework of 500+ requirements that you can customise in under 30 minutes.

Should ERP requirements be weighted or prioritised?

Yes. Prioritising requirements (must-have vs. nice-to-have) is essential for objective vendor evaluation. We recommend a three-tier approach: Phase 1 (must-have for go-live), Phase 2 (needed within Year 1), and Future Phase (long-term roadmap items). Our wizard automatically helps you assign priorities.

What is an ERP requirements template?

An ERP requirements template is a structured document or spreadsheet that lists the functional and technical requirements for an ERP system. It serves as the foundation for RFI/RFP documents sent to vendors during the selection process. You can download our Excel template or use our interactive wizard to build a custom requirements list.
