ERP Implementation Budget: What It Really Costs

Complete cost breakdown so you can budget accurately and avoid surprises.

Last Updated: July 2025|10 min read

Key Takeaways

  • Software licensing is typically 25-40% of total first-year cost
  • Budget $75K-$300K+ total for first year depending on system and complexity
  • Hidden costs like internal time and post-go-live support often catch companies off guard
  • Ongoing annual costs run 30-50% of first-year investment

ERP vendors will quote you software costs. What they won't tell you is that software is only part of the investment. Implementation services, data migration, training, and your team's time add up quickly.

This guide breaks down the complete cost picture so you can budget realistically. A fractional CFO can help you evaluate the ROI and plan your implementation budget.

Total Cost Overview

Company Size/ComplexityYear 1 TotalOngoing Annual
Simple ($5M-$15M, single entity)$75,000 - $150,000$30,000 - $60,000
Moderate ($15M-$35M, some complexity)$150,000 - $250,000$50,000 - $100,000
Complex ($35M+, multi-entity/international)$250,000 - $400,000+$80,000 - $150,000+

Cost Category Breakdown

1. Software Licensing

NetSuite$30,000 - $150,000+Users, modules, edition (SuiteSuccess tier)
Sage Intacct$20,000 - $80,000+Users, modules, entities
Microsoft Dynamics 365$25,000 - $100,000+Users, apps, configuration

2. Implementation Services

ServiceCost RangeDescription
Basic implementation$25,000 - $50,000Standard configuration, minimal customization
Standard implementation$50,000 - $100,000Moderate customization, integrations, reporting
Complex implementation$100,000 - $200,000+Heavy customization, multiple integrations, multi-entity

3. Data Migration

Often underestimated. Budget $10,000-$50,000 depending on:

  • Data volume and complexity
  • Cleanliness of source data (dirty data costs more)
  • Years of historical data to migrate
  • Number of source systems

4. Training

Budget $5,000-$20,000 for:

  • End-user training sessions
  • Administrator training
  • Documentation and job aids
  • Refresher training after go-live

5. Internal Time (Often Ignored)

Your team will spend significant time on the project. At a $100/hour fully-loaded cost, this adds up:

RoleHoursValue
Project lead (CFO/Controller)100-200 hours$10,000-$20,000
Finance team200-400 hours total$15,000-$30,000
IT support50-100 hours$5,000-$10,000

Hidden Costs to Watch

Scope creep: New requirements discovered mid-project. Build 15-20% contingency into your budget.
Third-party apps: Marketplace apps for specific functions. Budget $5,000-$20,000 annually.
Post-go-live support: Ongoing partner support after stabilization. Budget $10,000-$30,000/year.
Integration platform: If using Workato, Boomi, or similar. $10,000-$30,000/year.

Budget Planning Tips

Get multiple implementation partner quotes—prices vary significantly
Add 15-20% contingency for scope changes
Include internal time in your calculations
Budget for 12 months of post-go-live support
Plan for year 2-3 costs, not just year 1

ROI Perspective

While $100K-$300K sounds expensive, consider the cost of NOT upgrading: continued manual work, inability to scale, audit readiness issues, and poor decision-making from inadequate reporting. Most companies see positive ROI within 18-24 months.
