# Oracle NetSuite vs. a custom-built ERPStack system

**Typical Oracle NetSuite license cost:** $25,000 - $150,000+ / year (2026 list pricing)
**Lock-in risk:** Extreme (Proprietary SuiteCloud, annual tier price hikes)
**Modularity:** Low (Monolithic suite, forced to buy unused modules)
**Customization ceiling:** High friction (Requires expensive SuiteScript developers)
**Migration path:** Database extraction to custom PostgreSQL schemas via Drizzle ORM

## Feature comparison

| Feature | ERPStack (custom) | Oracle NetSuite |
| --- | --- | --- |
| API Extensibility | Native GraphQL & REST | Rate-limited SuiteTalk |
| Database Access | Direct SQL & Real-time replication | Locked behind proprietary views |
| UI Customization | Full React/Tailwind codebase | Limited drag-and-drop builder |
| Multi-Tenant Architecture | Yes | No |
| Manufacturing Modules (MRP & CMMS) | Custom MRP runs and CMMS maintenance scheduling built to your routing and BOM requirements | Advanced manufacturing tiers licensed separately |
| Industry Coverage | Construction job costing, field service scheduling, and wholesale distribution built for the mid-size firm | Vertical editions priced as separate SuiteApps |
| Total Cost of Ownership | Flat hosting; the business owns the software, database, and user management outright — benefits that compound as seats grow | $25,000-$150,000+ annual license plus per-module and per-user fees |

## Migration timeline

- **Audit & Mapping** (2 Weeks): Complete map of existing SuiteCloud data, custom fields, and integration requirements.
- **Data Extraction** (3 Weeks): Automated extract of records, files, and supporting information using our NetSuite connector.
- **Parallel Run** (4 Weeks): Both systems run side-by-side with real-time sync for validation — week 6-9 of the implementation timeline, with a defined exit gate closing each of the four phases.
- **Cutover** (1 Weekend): Final delta sync and DNS switch.

## Hidden costs of Oracle NetSuite

- **API Calls:** NetSuite charges for API concurrency. If your eCommerce store scales, your integration costs scale with it — a custom system on your own Postgres cluster meters 0 API surcharges at any volume.
- **Sandbox Environments:** Full-data sandboxes cost extra, hindering developer productivity. Custom builds ship unlimited staging environments at $0 incremental license cost.
- **Vendor Research & Selection Time:** Software selection projects burn weeks of internal research comparing vendors, user reviews, deployment options, and packaged solutions. A custom build replaces that roundup treadmill: you hire one senior engineering team, get a 2-week requirements audit and architecture review, and an expert fixed quote.
- **User Training & Adoption:** Every seat added to NetSuite is a license fee plus a training cost. Role-specific screens in a custom system cut onboarding to the 3-5 workflows each user actually performs, with free unlimited read-only access for auditors and management.

## Why teams leave

- Migrated from NetSuite to our custom ERP, saving $120k/yr on licensing and gaining real-time inventory for 15+ warehouses. (A multi-region retailer — Unpredictable renewal hikes and sluggish API.)
