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

Stockagile

Stockagile is not just a stock database; it bridges physical store hardware, multi-marketplace sync, and fashion variant matrices. While a basic stock-level tracking dashboard is easy to build, managing real-time inventory locks across physical stores and web channels without double-selling during peak traffic requires deep infrastructure resilience.

you can rebuild

  • Basic stock level CRUD interface and location tracking
  • Simple Shopify inventory webhook listener and update queue
  • Product variant matrix schema (season, color, size)
  • PDF purchase order generation for suppliers
  • Basic warehouse-to-warehouse stock transfer logging

what you lose

  • Native hardware driver integration for POS peripherals (receipt printers, barcode scanners)
  • Real-time bi-directional stock lock across marketplaces (Zalando, Amazon, El Corte Inglés)
  • Built-in EU regional fiscalization compliance (e.g., TicketBAI, Veri*Factu)
  • Offline-first POS checkout capability for physical store outages
  • Native B2B wholesale ordering portal with custom price books

real moats

  • Bi-directional integration network across physical POS hardware and EU marketplaces
  • Compliance with regional EU invoicing and fiscal anti-fraud laws
  • High operational switching cost for physical store employees
