Why Rent NetSuite When You Can Own Your ERP?
A secure, serverless Next.js and Postgres database deployment designed to bypass the licensing tax of Oracle NetSuite — with 100% code ownership at handover.
Quick Answer
In short: ERPStack provides a custom, license-free alternative to Oracle NetSuite. You get 100% data and IP ownership, zero seat-based fees, and a dedicated cloud deployment delivered in weeks.

Uncovering Hidden Constraints
What we don't do
Hidden Cost: API Calls — stacked on the $25,000 - $150,000+ / year (2026 list pricing) base license
What we do
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.
What we don't do
Hidden Cost: Sandbox Environments — stacked on the $25,000 - $150,000+ / year (2026 list pricing) base license
What we do
Full-data sandboxes cost extra, hindering developer productivity. Custom builds ship unlimited staging environments at $0 incremental license cost.
What we don't do
Hidden Cost: Vendor Research & Selection Time — stacked on the $25,000 - $150,000+ / year (2026 list pricing) base license
What we do
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.
What we don't do
Hidden Cost: User Training & Adoption — stacked on the $25,000 - $150,000+ / year (2026 list pricing) base license
What we do
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.
Legacy Pain Points
- Rigid, forced upgrades that break custom scripts
- License costs scaling with user seats
- Locked inside proprietary SuiteCloud frameworks
The Custom Code Advantage
- 100% intellectual property ownership with zero licensing fees
- Next.js performance with sub-50ms database response times
- PostgreSQL database level isolation you control
Migration Blueprint Specification
- Typical Annual Cost
- $25,000 - $150,000+ / year (2026 list pricing)
- Modularity
- Low (Monolithic suite, forced to buy unused modules)
- Customization Limits
- High friction (Requires expensive SuiteScript developers)
- Extraction Pathway
- Database extraction to custom PostgreSQL schemas via Drizzle ORM
The Escape Plan
Audit & Mapping
Complete map of existing SuiteCloud data, custom fields, and integration requirements.
Data Extraction
Automated extract of records, files, and supporting information using our NetSuite connector.
Parallel Run
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
Final delta sync and DNS switch.
Calculate Your 3-Year IP Savings
Drag the team-size slider to model SaaS licensing spend against a fixed-cost custom build — implementation, hosting, and 3-year TCO update in real time.
- • Base Implementation: $55,000
- • License Taxation: $270,000
- • Data Ownership: Rented
- • One-Time Build: $55,000
- Custom Hosting (3 Yrs): $10,800
- Maintenance & Support (3 Yrs): $24,750
- 100% Code & Data Ownership
Staying on per-seat licensing costs you $6,513 every month at 50 seats — spend that never converts into owned IP.
Why Companies Left Oracle NetSuite
"Migrated from NetSuite to our custom ERP, saving $120k/yr on licensing and gaining real-time inventory for 15+ warehouses."
Frequently Asked Questions
Mid-market companies typically save $30k to $150k annually in licensing fees by migrating to a custom-built solution, paying only for hosting costs.
NetSuite forces you to pay for features you never use and limits database access. A custom ERP matches your exact workflow with zero license tax, typically delivered as an 8-12 week build.
The implementation runs four phases over roughly 9 weeks: a 2-week audit and field mapping, 3 weeks of automated data extraction, a 4-week parallel run with real-time sync, and a weekend cutover. Each phase closes with a go/no-go checklist — row counts per table, checksum validation, ledger spot checks, and a tested rollback plan — before the next begins.
A mid-size firm spending $25,000+ annually on NetSuite licenses is the typical switch candidate: the benefits — zero per-seat fees, direct SQL access, and integrations without API metering — outweigh the 9-week build when headcount or order volume is growing. Companies with fewer than 5 users and fully generic workflows usually do better staying on a rented suite.
