Migration & switching to NetSuite

Moving off Sage, Xero, QuickBooks, SAP or a legacy ERP. With your history reconciled and your team still able to work.

The problem

Switching feels riskier than staying

Most companies stay on a system they’ve outgrown because the move looks dangerous. Lost history, broken balances, weeks of downtime. Done properly, those risks are manageable. The risk sits in how the ERP migration is run, and that part is controllable.

Seven ways in, one discipline

Every route below gets its own page, including Microsoft Dynamics, SAP Business One and legacy ERPs. The quirks of your current system decide the plan.

The payoff

What a clean switch to NetSuite buys you

History that survives

Open items and the years you need come across and reconcile, so you can prove nothing was lost at cutover.

A cutover, measured in days

One planned freeze over a month-end. Your team keys nothing twice.

A system that fits again

Multi-entity, multi-currency, real reporting. The limits you’ve hit are lifted.

Balances finance signs off

Every control account tied back to source before anyone relies on it.

How it works

One route, five checkpoints

  1. Assess – we profile your current system and agree what moves, what’s archived and when.

  2. Map – every field and value gets a documented home in NetSuite before anything is loaded (more on our data migration approach).

  3. Rehearse – the full migration runs into a sandbox first – never straight to production.

  4. Reconcile – balances tie back to your old system, account by account, and finance signs off.

  5. Cut over – one freeze, one final load, go-live with a rollback ready.

Good to know

What to know before you switch

  • !Timing matters. A month-end or year-end boundary makes reconciliation far cheaper. We plan around your calendar, and we’ll tell you if the date you want is a bad one.
  • !History has a price. Open items plus one or two years is usually right. A decade of transactions can come. It just costs mapping and testing time it rarely repays.
  • !Your old system stays for a while. Read-only access to the legacy system covers audits and the odd lookup. Switching it off on day one is a mistake nobody makes twice. We’ve run the reverse too: a year-long NetSuite decommissioning with archiving and audit cover, which the client says was delivered ahead of schedule.
Straight answers

NetSuite migration FAQs

How long does switching to NetSuite take?
The migration itself runs alongside the implementation. Typically six to twelve weeks of it. The full switch, system live and old one retired, is usually a four-to-nine-month project.
Will we lose historical data?
Not if it’s planned properly. You choose what comes across, and everything that does is reconciled to source. What doesn’t migrate stays archived and readable.
How much does it cost to switch to NetSuite?
It depends on scope: the system you’re leaving, how much history comes across, how many entities you run and the implementation around it. We scope before we quote – see how we charge.
Can you migrate us if another partner does the build?
Yes. Migration is a workstream we regularly deliver inside other partners’ projects. And we’ll tell you plainly how theirs is going.
