Start with Fulfil.io — highest vibe code, weakest moat.
Cegid
An AI can easily write the web UI for a POS register and a multi-location inventory DB. You cannot AI-prompt your way through strict national anti-fraud tax compliance laws (like French NF525 or German KassenSichV) or driver integration across decades of physical retail hardware.
you can rebuild
- Basic Point of Sale (POS) register checkout interface and barcode lookup.
- Product catalog management with multi-attribute matrix SKUs (Style, Color, Size).
- Basic multi-location inventory tracking and stock transfer requests.
- Omnichannel order routing basics (BOPIS, Ship-from-store rules).
- Basic store sales reporting and daily register closing tallies.
what you lose
- Certified compliance with local tax and fiscalization authorities across 80+ countries.
- Plug-and-play integrations with legacy retail hardware, barcode scanners, cash drawers, and EFT terminals.
- Advanced Open-to-Buy (OTB) merchandise planning and seasonal assortment management tools.
- Enterprise-grade offline register synchronization hardened for multi-day store internet outages.
- Turnkey integration with legacy logistics, WMS, and international carrier networks.

Fulfil.io
Fulfil.io is a full-featured cloud ERP built on top of the Tryton framework. While an AI agent can build a basic inventory dashboard in a weekend, replicating FIFO valuation, landed costs, audit-proof GL accounts, and real-time multi-channel inventory lock management is a massive software engineering endeavor.
