SAP to NetSuite migration

The problem

Signs SAP has outgrown your business

Your business relies on SAP, but running SAP has become a business of its own. For a mid-market company, the licence fees, support contract and delays to every change are getting hard to justify. SAP’s own maintenance strategy ends mainstream maintenance for SAP ECC (Business Suite 7) at the end of 2027, with optional extended maintenance to the end of 2030, so many mid-market SAP users now face a decision either way.

What we do

How we migrate from SAP to NetSuite

Nothing reaches production until it has balanced in a sandbox.

Clear scope mappingWhat SAP does that you use, what it does that you don’t and what NetSuite covers – in writing.
Data model translationSAP’s structures flattened into NetSuite’s without losing the controls that matter.
Extraction, handledClean extracts from SAP tables – a job we’ve done many times.
Process simplificationApproval chains and postings redesigned for a system your team can run day to day.
Reconciled balancesOpening positions tied to SAP before cutover.
Exit planLicences, support contracts and archive access sequenced so nothing lapses early.

The payoff

What switching buys you

Your data, reconciled

Open items and the history you choose come across and reconcile.

Days, planned

One freeze over a month-end – your team shouldn’t need to key anything twice.

Room the old system never had

Entities, currencies, reporting – with far more room to grow.

Sign-off, in writing

Every control account tied to source before go-live.

How it works

Five checkpoints

No checkpoint passes without your sign-off.

Assess – we profile the current system and agree what moves, what’s archived and when.
Map – every field and value gets a documented home in NetSuite before anything is loaded.
Rehearse – the full migration runs into a sandbox first – never straight to production.
Reconcile – balances tie back to the old system, account by account, and finance signs off.
Cut over – one freeze, one final load, go-live with a rollback ready.

Good to know

What to know before you start

!Some SAP depth won’t map – by design. Heavily configured SAP processes are the cost you’re escaping; expect simplification, and we’ll flag anywhere that simplification bites.
!This is a re-implementation, priced as one. Nobody ‘lifts and shifts’ SAP into NetSuite. Processes get redesigned, and the project should be scoped that way from the first call.
!Your SAP knowledge is an asset. The people who know why SAP was configured that way are essential to the design workshops – book their time early.

Straight answers

SAP to NetSuite Migration FAQs

Can NetSuite really replace SAP?

For most mid-market operations, yes – with deliberate simplification. For deep manufacturing or industry-specific SAP estates, we’ll show you where the limits are before you commit.

What does SAP ECC end of support mean for us?

SAP ends mainstream maintenance for ECC at the end of 2027, and optional extended maintenance runs to the end of 2030 at extra cost. That leaves three main routes: move to SAP S/4HANA, pay for extended maintenance while you plan, or right-size to NetSuite. For a mid-market business, compare the full cost and effort of each before committing, as a move to S/4HANA is a major project too.

How long does SAP to NetSuite take?

Typically nine to eighteen months for multi-entity or heavily customised SAP estates, and five to eight months for a simpler single-entity setup with integrations. The data migration workstream typically runs six to twelve weeks within that. Be wary of shorter timelines.

How much does an SAP to NetSuite migration cost?

Moving from SAP to NetSuite is a re-implementation rather than a data transfer, so it’s priced as one. The cost depends on the number of entities, how much process redesign is needed, your integrations and how much history you bring across. For typical UK figures, see what a NetSuite implementation costs.

What happens to our SAP history?

When you migrate from SAP to NetSuite, we bring across and reconcile your key history, then archive the rest so you can still view it. Regulatory retention requirements are planned for from the start – HMRC generally expects company records to be kept for six years.

What happens to our VAT returns during the move?

Where possible, cut over at the start of a VAT period, so each return comes from one system. File the last return before cutover from SAP, and have NetSuite’s MTD for VAT set up before the first return is due.

NetSuite vs SAP – which fits a mid-market business?

NetSuite vs SAP is usually a size question. S/4 assumes an IT function and a budget to feed it; NetSuite assumes neither. For SAP Business One or Business ByDesign users the comparison is closer, but multi-entity growth tips it the same way – and the running costs differ enough that our cost and pricing guide is worth ten minutes before any demo.
