NetSuite Implementation Checklist: 12 Things Before You Sign

Most NetSuite implementations are won or lost before the first configuration is built — in the scope conversation, the statement of work, and the decisions nobody pinned down. By the time a project is "in trouble," the cause usually traces back to something that should have been settled before signing.

This is the checklist we wish every company ran before committing to a NetSuite implementation. Twelve things to settle — with your partner, and internally — so the project starts on solid ground.

1. A specific, written definition of go-live

"Go-live" has to mean something concrete. Which modules are live, which processes run in NetSuite, which integrations are connected, what the old system is still doing. If go-live isn't defined in writing, it becomes a moving target — and every party will remember the definition differently when the date approaches.

2. What's in the SOW — and what's explicitly not

The statement of work should list deliverables specifically, not in categories. "Data migration" is not a deliverable; "migrate customers, vendors, items, open AR/AP, and trailing 12 months of transactions, with a reconciliation report" is. Equally important: what's explicitly excluded, so a phase-two item doesn't turn into a mid-project billing dispute.

3. How change requests are priced and approved

NetSuite implementations always generate new requests once people see the system. Settle, before signing, how a change request gets scoped, priced, and approved — and who on your side has the authority to approve one. Without this, scope creep has no brakes.

4. The data migration plan

Decide what data migrates and what doesn't. Open transactions and current balances, almost always. Ten years of closed orders, almost never. Confirm who cleans the source data — you or the partner — and that there's a reconciliation step where finance proves the migrated numbers tie out. Data is the most underestimated part of every implementation; pin it down first.

5. Every integration, named

List every system NetSuite has to connect to — ecommerce, CRM, payroll, shipping, banks, EDI, BI. For each, decide: connector or custom build, real-time or batch, who owns it. An integration discovered mid-project is a schedule and budget event. Discover them all now.

6. Who staffs the project — by name

Ask which consultants will actually deliver the work, and whether the senior people in the sales process stay on the project. "Our team" is not an answer. Get names and roles. Many partners sell senior and deliver junior; the time to surface that is before you sign, not on the first status call.

7. Your internal team's time commitment

The partner configures NetSuite; they cannot make your business-process decisions. Identify who from finance, operations, and IT will be available, and how much of their time the project needs. If those people are still doing their day jobs at 100%, the project will stall in the gaps. An honest implementation plan includes your team's hours, not just the partner's.

8. An empowered executive sponsor

NetSuite touches finance, operations, sales, and IT at once, and those groups will disagree. Name one senior person with the authority to settle cross-department disputes. A project owned by someone who has to escalate every decision moves at the speed of escalation.

9. The customization philosophy

Agree, in principle, on how much you'll customize. Every script and custom workflow is something to maintain and test against two NetSuite releases a year. The goal is to adapt your process to NetSuite's strengths where reasonable, and customize only where the business genuinely requires it — not to rebuild your old system inside NetSuite.

10. The testing plan

Confirm there is real testing before go-live — a genuine month-end, a real order-to-cash cycle, a real fulfillment, run in the sandbox by your people, not a vendor demo. Settle who writes the test scripts and who signs off. Untested go-lives are how problems reach production.

11. Training and the first weeks after go-live

Who trains your users, when, and on what. And critically: what support looks like in the first weeks after go-live, when real problems surface. A partner whose engagement effectively ends at go-live leaves you alone for the hardest part.

12. The total first-year number

Get the full first-year figure on the table: license, implementation services, integrations, and a realistic contingency. Implementations commonly run 1-2x the annual license fee in services. A number that assumes everything goes perfectly is not a budget — it's a hope.

Run the checklist before the contract, not after

None of these twelve items is exotic. They're the things experienced teams settle as a matter of course — and the things rushed projects skip, then pay for later. Walking a partner through this checklist is also a test: a good partner will have crisp answers and will respect the questions. A partner who gets vague or defensive is telling you something useful, while you can still act on it.
