our call
Start with Anvyl — highest vibe code, weakest moat.
Anvyl
Anvyl combines purchase order workflow management with real-time freight tracking and multi-party supplier communication. While an AI agent can build a internal PO milestone schema in a few days, integrating messy logistics carrier APIs and forcing overseas factories to use a custom software portal creates massive operational friction.
you can rebuild
- Purchase order lifecycle status tracking and state transitions
- Production milestone timeline visualization and delay calculation
- Item-level SKU quantity, landed cost estimation, and defect tracking
- Automated milestone delay alerts to internal team channels
- Centralized document repository for invoices and bills of lading
what you lose
- Turnkey integrations with ocean, air, and parcel freight telemetry providers
- Pre-built external supplier portal with authentication and localized UI
- Automated container tracking webhooks linked directly to PO line items
- Supplier performance historical benchmarking and SLA analytics
- Enterprise SAML/SSO governance for external vendor access
real moats
- Pre-integrated connectivity with legacy freight forwarder systems and ocean tracking networks
- Supplier familiarity with Anvyl portal workflows across multiple brand accounts
- Normalization layer for multi-country factory formats and commercial documents

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.

- Manual stock adjustment interface

what you lose
- Integrated double-entry general ledger accounting compliant with GAAP/IFRS
