our call
Start with Fulfil.io — highest vibe code, weakest moat.
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.

- Simple inventory stock count dashboard across locations
- Basic Purchase Order creation and PDF export
- Manual stock adjustment interface
- Vendor contact directory and catalog list
- Basic order status tracking dashboard
what you lose
- Integrated double-entry general ledger accounting compliant with GAAP/IFRS
- Real-time landed cost allocation incorporating freight, customs, and duties into COGS
- Barcode-scanner-compatible mobile WMS workflows for picking, packing, and receiving

Zendrop
Building a Shopify app that listens to order webhooks and forwards them to a supplier API takes less than a week. However, Zendrop's real product is its network of vetted factories, US/China physical warehouses, and pre-negotiated express shipping lines. AI cannot code physical inventory or negotiate freight contracts.
