Replacing Great Plains costs more than a software subscription. The real budget spans licensing, implementation, data conversion, integrations, training, and your team's internal time. Understanding the full picture — and right-sizing the platform — is how you control it.
The cost components.
| Component | What it covers |
|---|---|
| Software licensing | Subscription or license fees for the new platform, by users and modules. |
| Implementation | Configuration, setup, and project work by the implementation partner. |
| Data conversion | Migrating and cleaning historical data and opening balances from GP. |
| Integrations | Reconnecting payroll, banking, CRM, and operational tools. |
| Training | Getting the team productive on the new system. |
| Internal time | Your staff's hours — the most underestimated cost. |
The biggest cost lever: choosing the right size.
The spread between platforms is enormous — a QuickBooks move is a fraction of a multi-entity NetSuite implementation. That means the most important cost decision isn't negotiating licensing; it's choosing a platform that genuinely fits. Two failure modes drive runaway cost:
- Over-buying: implementing a heavy ERP you don't need, then paying to run capability you never use.
- Under-buying: choosing a platform you outgrow in a few years, then paying for a second migration.
How to control the cost.
- Right-size the platform to your real complexity — not the vendor's upsell.
- Clean your data before conversion, not during.
- Redesign the chart of accounts instead of copying GP's.
- Scope integrations deliberately; each one adds cost and risk.
- Govern the implementation partner so the project doesn't sprawl.
This is exactly where an independent advisor pays for itself: we help you choose the right-sized platform and govern the project, which is where the real money is saved.
Questions we hear.
How much does it cost to replace Great Plains?
Total cost spans software licensing, implementation, data conversion, integrations, training, and internal time. The range is wide: a QuickBooks move is far less than a multi-entity NetSuite implementation. Because the spread is so large, selecting the right-sized platform is the single biggest cost lever.
What are the main cost components of an ERP migration?
Software/subscription licensing, implementation and configuration, data conversion and clean-up, integrations to other systems, training, and the internal time your team spends on the project. Internal time is the most commonly underestimated piece.
Why is choosing the wrong platform the most expensive outcome?
Because it can mean paying for capability you don't use, or outgrowing a platform and re-migrating within a few years. Either way you pay for two projects. Getting selection right up front is far cheaper than correcting it later.
Can we reduce migration cost?
Yes — by right-sizing the platform, cleaning data before conversion, redesigning rather than copying the chart of accounts, scoping integrations carefully, and governing the implementation partner so the project doesn't sprawl. Good planning is the cheapest part of the project and saves the most.
Not sure which platform fits?
That's exactly the call we help you make — objectively, before you commit to an implementation. We specialize in QuickBooks, Sage Intacct, and NetSuite.
