NetSuite data migration: clean, reconciled and ready for audit.
Data migration sinks more NetSuite projects than any other workstream. I've moved data from SAP, Sage, Xero, QuickBooks, Salesforce, NAV and bespoke databases, always with reconciliation, sign-off and a paper trail finance can defend.
When you need this
A new NetSuite implementation, a system replacement, an M&A consolidation, or bringing a newly acquired subsidiary into your existing NetSuite account.
What's included
- ETL from SAP, Sage, Xero, QuickBooks, Salesforce, NAV
- Static data: customers, vendors, items, COA
- Open transactions: AR, AP, POs, SOs, items in transit
- Historical TB and movement data
- Multi-book and multi-currency handling
- Field-level mapping documentation
- Reconciliation and sign-off framework
How I work
How a NetSuite data migration project runs.
Step 1
Scope and cleanse
Decide what moves: master data, open items, balances and how much history. Duplicates and dead records are cleared before they reach NetSuite.
Step 2
Map
A field-level mapping document for every record type, agreed with the people who own the data.
Step 3
Rehearse
Trial loads into a sandbox, each reconciled to the source system's trial balance, aged debtors and creditors, and stock.
Step 4
Cut over and sign off
The final load in an agreed cutover window, with a reconciliation pack finance signs off and auditors can follow.
How much history should you migrate to NetSuite?
Most businesses bring across master data, open transactions and opening balances, plus period trial balances so year-on-year reporting still works.
Full transaction history is possible, but it costs more to map and reconcile, and it's often better kept in an accessible archive of the old system. I'll help you decide based on your reporting, audit and record-keeping needs, rather than moving everything by default.
Multi-currency and Multi-Book accounting need extra care: exchange rates, revaluation and book-specific balances all have to land correctly, or the first close will show it.

FAQ
NetSuite Data Migration: common questions.
Which systems can you migrate from?
SAP, Sage, Xero, QuickBooks, Salesforce, Microsoft NAV and bespoke databases. If your system can export data, it can be migrated.
Who cleans the data?
You own the data, so your team decides what's correct. I provide the templates, validation checks and exception reports that make cleansing quick and keep it visible.
Can you migrate a new subsidiary into our existing NetSuite account?
Yes. Onboarding an acquired business into an existing OneWorld account is a common project, and it needs the same mapping, rehearsal and sign-off as a full implementation.
Is data migration part of an implementation or separate?
Either. It's usually a workstream within a NetSuite implementation, but I also take on migrations on their own.
