What Is ERP Implementation?
ERP (Enterprise Resource Planning) implementation is the end-to-end process of selecting, configuring, deploying, and migrating data to a new ERP system. For most mid-market companies, this means replacing or significantly upgrading the core operational and financial system that manages accounting, inventory, purchasing, production, and HR.
Major ERP platforms in the mid-market include NetSuite, SAP Business One, Microsoft Dynamics 365, Sage Intacct, and Oracle Cloud.
The ERP Implementation Process
A typical ERP implementation follows these phases:
- Selection, Evaluating vendors, issuing RFPs, comparing capabilities against requirements
- Project scoping, Defining modules, users, integrations, and go-live timeline
- Configuration, Setting up the system to match business processes (chart of accounts, workflows, approval chains)
- Data migration, Cleaning, mapping, and loading historical data from legacy systems
- Integration, Connecting the ERP to other systems (CRM, production, payroll, e-commerce)
- Testing, User acceptance testing, parallel runs, data validation
- Training, Teaching users how to operate the new system
- Go-live and stabilization, Cutover to the new system, hypercare support period
Why ERP Implementations Fail
ERP implementations have a well-documented failure rate. Gartner estimates that 55-75% of ERP projects fail to meet their objectives, going over budget, over timeline, or failing to deliver expected benefits. In conversations with mid-market finance leaders, the pattern is consistent:
“People promise you the moon, it’s six months and $40,000, and it’s then a year and a half and $120,000, and it still doesn’t work.”, Fractional CFO
“90% of ERP implementations are disasters.”, CFO, Steel Manufacturing
Common failure modes:
Scope creep: Initial project scope expands as stakeholders realize how many edge cases their business has. Every customization adds time and cost.
Data quality problems: Migrating dirty, inconsistent legacy data into a new system imports the old problems into the new system.
Change management failure: Users revert to spreadsheets when the new system is harder to use than the old one. Adoption is never guaranteed.
Integration underestimation: The ERP is one system in an ecosystem of many. Integrating it with other tools, production systems, 3PLs, CRMs, is often more complex than the ERP itself.
Vendor overpromising: ERP vendors sell to the ideal case. Implementation partners bill for time regardless of outcome.
ERP Implementation Costs
Mid-market ERP implementation costs vary widely, but typical ranges:
| Company Size | Software License | Implementation Services | Total |
|---|---|---|---|
| $10M-$50M revenue | $30K-$100K/yr | $50K-$200K | $80K-$300K |
| $50M-$200M revenue | $100K-$300K/yr | $200K-$600K | $300K-$900K |
| $200M+ revenue | $300K-$1M+/yr | $1M-$5M+ | $1.3M-$6M+ |
These are software and services costs. They exclude internal staff time, productivity losses during transition, and stabilization costs post-go-live.
Alternatives to Full ERP Replacement
Many mid-market finance leaders are discovering that full ERP replacement isn’t the only path to better financial visibility. The alternative: keep existing ERPs and build a data integration layer on top that connects disparate systems into a single source of truth.
This approach:
- Avoids the risk and cost of ERP migration
- Delivers financial visibility faster (weeks vs. 18 months)
- Works across multiple ERPs simultaneously
- Doesn’t disrupt operational systems that are working
For companies with legacy ERPs that “work” for operations but fail for reporting, this is often the higher-ROI path.
How Go Fig Fits Into ERP Strategy
Go Fig doesn’t replace ERPs, it connects them. Whether a company has one ERP that needs better reporting or five ERPs across acquired entities that need consolidation, Go Fig builds the data layer that makes financial visibility possible without disrupting the operational systems the business depends on.
