Fast-growing mid-market, multi-subsidiary

Overview

NetSuite started life as NetLedger in 1998, one of the first true cloud-native ERPs, and has been owned by Oracle since 2016. It runs financials, CRM, inventory, order management, and ecommerce on one shared database, which is why it's usually the first “real ERP” a company moves to once spreadsheets and QuickBooks stop working. Tens of thousands of companies run on it today, most commonly mid-market businesses with more than one legal entity.

Best for: Fast-growing mid-market companies that need one system to consolidate multiple subsidiaries.

How it works

NetSuite is a single multi-tenant application where financials, inventory, orders, and CRM records all live in one database. Understanding how that database is structured explains most of the platform's strengths and most of its frustrations.

One database, subsidiaries as a dimension

In OneWorld, every subsidiary is a node in a hierarchy inside the same account rather than a separate instance. Transactions carry the subsidiary they belong to, and consolidation happens by rolling up that hierarchy, with intercompany eliminations posted automatically to designated accounts.

The practical consequence is that adding a legal entity is a configuration task, not a new implementation, and that group reporting is a saved search or report filtered by hierarchy level rather than an export-and-merge exercise. It also means chart-of-accounts discipline matters enormously: a segment structure defined loosely in month one shows up as unreportable data in year two.

Records, transactions, and the order-to-cash flow

Everything in NetSuite is a record: customers, items, sales orders, invoices, purchase orders, work orders. Records reference each other, so a sales order can generate a fulfilment, an invoice, and the revenue schedule behind it while remaining linked back to the original document.

That linkage is why the order-to-cash flow is coherent: inventory decrements when fulfilment posts, cost of goods hits the ledger at the same moment, and receivables and revenue recognition follow from the same transaction rather than from a monthly import. Companies coming from separate accounting and inventory systems usually find this is the single largest process improvement.

Customisation: SuiteScript, SuiteFlow, and the cost of both

NetSuite is customised through SuiteFlow for workflows and SuiteScript for code, plus custom records and fields. This flexibility is genuine — most process gaps can be closed — but each customisation becomes something to maintain and regression-test across the two annual releases.

The teams that stay happy on NetSuite tend to keep a written inventory of every script and workflow, review it annually, and delete what is no longer used. The teams that struggle inherited a decade of undocumented customisation from a departed partner.

Reporting and the close

Reporting is built on saved searches and report builder, both powerful and both with a learning curve that surprises people expecting a drag-and-drop experience. Most finance teams designate one person as the reporting owner within a few months of go-live.

For the close itself, period locking, approval routing, and the close checklist are native, and the consolidated close runs off the same hierarchy used all month. Teams commonly report a multi-day reduction in close time after moving off separate systems, driven mostly by eliminating manual consolidation and reconciliation steps.

FAQ

How it stacks up against Light

NetSuite is a strong, proven system, but it was built as a traditional ERP first and a multi-entity tool second. Light was built multi-entity and multi-currency from day one, with an 8-week implementation guarantee instead of NetSuite's typical 4 to 9 months.
