NetSuite implementations, run by accountants who happen to know NetSuite.
- DISCOVER (~2 mo): BRD, Future State Design, Data Strategy. Every requirement classified as Align, Adapt, or Accommodate.
- REALIZE (4-5 mo): Configuration, integrations, custom workflows. Heaviest phase by hours. Full UAT with real data.
- EDUCATE (~2 mo): Role-based training, super-user enablement. Your team learns the system before go-live, not during it.
- ACTUALIZE (~2 mo): Cutover, go-live, hypercare. Same consultants stay through stabilization.
- MAXIMIZE (~1 mo): Post-go-live optimization. Optional handoff to SuiteCare managed services.
Move from QuickBooks, Sage, Microsoft GP, or any legacy system.
Three triggers bring most buyers to a NetSuite migration: revenue passing $20M and the manual close stops working, on-prem ERP nearing end-of-life with rising maintenance costs, or a PE sponsor demanding a Day-5 close the current platform cannot deliver. GSI runs the discovery, mapping, validation, and cutover work so you move without losing data, history, or operational continuity.
- QuickBooks, Sage, Microsoft Dynamics GP, and custom legacy migration
- Field-level data mapping and validation
- Mock cutovers (typically two before go-live)
- Long-weekend cutover planning with rollback plan
- Zero data loss commitment
A NetSuite assessment, not a sales pitch wrapped in one.
- Written assessment, 25 to 40 pages with severity-ranked findings
- Prioritized roadmap: fix these three things first
- Executive presentation, 60-minute working session
- Read-only environment access, 6 to 10 hours of your team's time total
- Outcome-agnostic: keep, optimize, remediate, or restart
When your current NetSuite implementation is going sideways.
GSI has a team of NetSuite project rescue experts. Recovery typically addresses three symptoms: budget overruns, missed timeline milestones, or functional gaps that did not surface until UAT or go-live. We diagnose what is recoverable and what is not, then execute the recovery in 4 to 12 weeks. Same consultants run the assessment and the execution. After go-live, the engagement transitions cleanly into SuiteCare.
- UAT keeps revealing gaps your partner did not anticipate
- Timeline has slipped twice with no firm new go-live date
- Budget overruns of 30% or more
- Customizations stacking up faster than they are tested
- Users pushing back and the project team is dismissing feedback
