our call
Start with Erply — highest vibe code, weakest moat.
Erply
Erply controls the operational plumbing of retail: physical receipt printers, payment terminal bridges, offline sync queues, and matrix item variants. Building a basic web inventory list with AI is easy, but maintaining network-resilient register hardware integrations and complex FIFO inventory ledgers across physical locations is not feasible with prompt-generated software.
you can rebuild
- Product catalog management and matrix variant definitions
- Customer records and simple loyalty points tracking
- Basic manual stock adjustments and intra-warehouse transfer orders
- Web-based register UI for touch-screen product selection
- Standard sales dashboard reporting and inventory valuation metrics
what you lose
- Native local hardware wrappers for receipt printers, cash drawers, and barcode scanners
- Offline-first POS register state engine using local browser storage and sync queues
- EMV credit card reader direct integrations (Ingenico, Verifone, PAX)
- Fiscal memory cash register compliance modules for strict European tax jurisdictions
- Automated purchase order generation based on historic reorder points
real moats
- Hardware integration layer abstracting physical payment terminals and peripherals
- Operational switching costs associated with retraining retail floor staff across multiple locations
- Localized retail fiscal tax compliance and audit-trail engines

NetSuite
NetSuite is an enterprise accounting, inventory, and compliance machine built on 25 years of complex tax rules and transactional integrity. While an AI prompt can easily output a polished CRUD dashboard for orders and inventory, it cannot build a compliant, multi-subsidiary, audit-ready double-entry ledger that passes an independent audit.
you can rebuild
- Basic SKU level inventory tracking and multi-warehouse stock viewing.
- Simple purchase order creation and receiving workflows.
- Basic sales order management and invoice generation.
- High-level customer and vendor master record management.
- Simple financial dashboards for cash-in vs cash-out metrics.
what you lose
- Enterprise-grade audit readiness and compliance with ASC 606, GAAP, and IFRS.
- OneWorld multi-subsidiary real-time automated financial consolidation and currency revaluation.
- Deep suite of turnkey integrations with global enterprise banking, tax engines (Avalara), and logistics providers.
- Advanced Warehouse Management System (WMS) functionality with bin tracking, wave picking, and mobile RF scanning.
- SuiteScript/SuiteTalk extensibility framework used by enterprise systems integrators.
real moats
- Decades of deeply embedded accounting, tax, and revenue recognition compliance logic.
- Immutable auditability accepted by enterprise auditors, public market regulators, and Big Four accounting firms.
- Deep SuiteCloud developer platform with thousands of custom SuiteScripts baked into enterprise operations.
- High switching costs: migrating off an established ERP takes 6-18 months and millions of dollars.
