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

OrderWise
OrderWise combines complex database state management with physical warehouse operations, Android handheld scanning hardware, and direct UK courier integrations. While an AI agent can build a simple web dashboard for stock counts, it cannot safely replicate real-time bin location routing, thermal printing infrastructure, or full inventory accounting.
you can rebuild
- Basic inventory quantity tracking across stock keeping units
- Manual purchase order generation and supplier management
- Low-stock threshold notifications and reorder triggers
- Centralized multi-channel order listing web view
- Basic sales velocity and inventory valuation reporting
what you lose
- Rugged Android handheld terminal scanner software and physical bin verification workflows
- Dynamic pick route optimization (wave picking, batch picking, trolley picking)
- Direct thermal printer integration for automated UK carrier label generation
- Batch and serial number traceability across multi-bin warehouse configurations
- Making Tax Digital (MTD) compliant accounting and landed cost calculations
real moats
- Deep physical operational lock-in with warehouse hardware, thermal printers, and handheld devices
- Massive integration surface spanning UK couriers, marketplaces, and accounting systems
- High switching cost driven by physical warehouse re-barcoding and warehouse staff retraining
