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

Sourcify

While the SaaS timeline tracker and sample approval UI takes days to replicate, Sourcify's core value is human: vetted overseas manufacturer relationships and local quality control inspectors. Rebuilding the web app leaves you without verified suppliers, factory audits, or boots on the ground.

you can rebuild

  • Tech pack builder and revision history log
  • Production milestone tracking dashboard
  • Sample submission and feedback approval workflow
  • Purchase order management and deposit status tracker
  • Centralized vendor contact directory

what you lose

  • Access to a pre-vetted network of overseas factories
  • On-site physical pre-shipment quality assurance inspections
  • Dispute negotiation with international suppliers
  • Factory benchmark pricing and production capacity data
  • Freight forwarding and import documentation coordination

real moats

  • Vetted network of physical manufacturing partners across Asian production hubs
  • On-the-ground quality inspection infrastructure and local personnel
  • Proprietary factory pricing, lead-time, and defect rate data
