our call

Start with Duoplane — highest vibe code, weakest moat.

Duoplane

Duoplane's fundamental feature—splitting orders by vendor and emailing purchase orders—can be built with an AI coding agent in a weekend. However, if your suppliers require legacy protocols like EDI X12, custom SFTP CSV parsing, or email scraping, maintaining custom pipelines becomes expensive fast.

you can rebuild

  • Automatic splitting of customer orders into vendor-specific purchase orders
  • PDF purchase order generation and automated vendor email dispatch
  • Vendor self-service portal for updating tracking numbers and stock levels
  • SKU-to-supplier catalog mapping with wholesale margin configuration
  • Automated shipment tracking synchronization back to the storefront API

what you lose

  • Pre-built support for EDI X12 automated order transmission
  • Built-in SFTP file polling and schema normalization for non-technical vendors
  • Automated PDF invoice parsing from supplier email replies
  • Out-of-the-box vendor accounting and cost of goods sold reconciliation logic
  • Multi-store unified routing rules engine across different e-commerce platforms

real moats

  • Broad integration coverage for legacy supplier communications (SFTP, EDI, legacy email schemas)
  • Operational lock-in via custom supplier workflow rules built over time
  • Handling complex edge cases like partial shipments, split shipping tax calculations, and backorders

OneStock

Building an order routing engine and a store pick-and-pack app using AI code generation is achievable in weeks. However, replacing OneStock in an enterprise setting fails because of the brutal reality of integrating with hundreds of legacy store POS terminals, custom ERP setups, and disparate regional carrier APIs.

you can rebuild

  • Basic order allocation and multi-location inventory tracking.
  • Simple rule-based order routing (e.g., nearest store, full order fulfillment).
  • Mobile pick, pack, and ship-from-store associate web interface.
  • Click & Collect (BOPIS) order staging and customer notification status workflows.

what you lose

  • Pre-built enterprise connectors for legacy POS systems (Aptos, Cegid, GK Software, Oracle Xstore).
  • Turnkey integrations with dozens of international and regional last-mile shipping carriers.
  • Battle-tested store associate UI optimized for high-throughput, low-friction store fulfillment.
  • Enterprise SLAs, SOC2/GDPR compliance assurance, and dedicated multi-tier support during peak holiday events.

real moats

  • Deep out-of-the-box connectors for legacy retail ERPs (SAP, Oracle, Dynamics) and proprietary POS systems.
  • Extensive pre-built integrations with European and global regional carrier networks for instant label generation.
  • Field-tested store associate mobile workflows refined across thousands of non-technical retail workers.

Questions people ask

Which is easier to rebuild with AI, Duoplane or OneStock?

Duoplane. It scores 6/10 on vibe code with a moat of 3/10, so an AI-assisted MVP takes about 1-2 weeks and a full replacement about 6-12 months, due to legacy supplier integrations (FTP/EDI/Email format fragmentation).

Which one costs less, Duoplane or OneStock?

Duoplane at $499/mo/mo for a typical mid-market store. The gap between the two is about $138,012/mo a year.

What do I lose if I replace Duoplane?

Pre-built support for EDI X12 automated order transmission Built-in SFTP file polling and schema normalization for non-technical vendors Automated PDF invoice parsing from supplier email replies

What do I lose if I replace OneStock?

Pre-built enterprise connectors for legacy POS systems (Aptos, Cegid, GK Software, Oracle Xstore). Turnkey integrations with dozens of international and regional last-mile shipping carriers. Battle-tested store associate UI optimized for high-throughput, low-friction store fulfillment.
