Start with Pulpo WMS — 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

Pulpo WMS
Pulpo WMS handles physical warehouse operations like mobile barcode device triggers, offline data queueing, bin pathfinding, and multi-channel order allocation. While building a web dashboard for inventory counts takes hours with AI, building software that reliably runs on rugged Zebra devices in warehouse Wi-Fi dead zones takes months. Replacing this requires hardware testing and operational field validation.
you can rebuild
- Shopify and WooCommerce order fetching logic
- Warehouse location hierarchy database (Zone, Aisle, Shelf, Bin)
- Basic inventory count updates and stock movement logs
- Packing list generation and printable order summaries
- Web admin dashboard for inventory monitoring
what you lose
- Native support for Android Zebra/Honeywell industrial hardware barcode scanners
- Offline-first synchronization for warehouse Wi-Fi dead zones
- Dynamic wave, batch, and zone picking route optimization
- Hardware-level direct printing integrations (Zebra ZPL drivers)
- Real-time physical audit trails with hardware scan validation
