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

real moats

  • Integration with physical barcode hardware and warehouse devices
  • High switching costs associated with retraining physical warehouse staff
  • Multi-carrier shipping and ecommerce platform integration web
