our call

Start with SoStocked — highest vibe code, weakest moat.

CIN7 Omni

You can easily build a custom inventory sync and PO tool using modern stack frameworks in a few weeks. However, fully replacing Cin7's multi-channel state locking, landed-cost accounting, nested BOM assemblies, and deep 3PL/Xero integration matrix takes significant engineering time.

you can rebuild

  • Centralized catalog and multi-location inventory dashboard
  • Basic multi-channel stock sync across Shopify and BigCommerce
  • Simple Purchase Order generation and supplier contact management
  • Basic kit and bundle static disassembly
  • Standard order routing and fulfillment status tracking

what you lose

  • Native, verified two-way sync with Xero and QuickBooks Online.
  • Built-in EDI and 3PL connections without custom middleware.
  • Turnkey B2B portal and built-in POS registration module.
  • Native mobile WMS barcode scanning apps for warehouse staff.
  • Material Requirements Planning (MRP) auto-purchase suggestions.

real moats

  • Decades of edge-case handling for tax rules, landed costs, and multi-currency accounting reconciliations.
  • Pre-built, pre-certified integration matrix across hundreds of EDI networks, 3PLs, and sales channels.
  • Deep workflow lock-in across warehouse, accounting, and sales operations teams.

SoStocked

SoStocked combines Amazon SP-API sales velocity syncing with configurable inventory forecasting and purchase order workflows. While writing moving-average velocity math in Python or SQL takes a few hours, dealing with Amazon API throttling, restock limits, and multi-stage supplier lead times makes a custom build tedious to maintain.

you can rebuild

  • Sales velocity calculations using 7, 30, and 90-day moving averages
  • Automated purchase order PDF generation and supplier email triggers
  • Configurable safety stock and reorder point math
  • Manual velocity overrides for planned promotional spikes
  • Basic supplier lead time tracking and reorder alerts

what you lose

  • Pre-built Amazon SP-API sync with automated token refreshing and rate-limit backoff
  • Real-time visibility into Amazon FBA storage capacity and restock limits
  • Automated algorithm for purging out-of-stock days from baseline velocity math
  • Multi-warehouse transfer planning UI for moving stock from 3PL to FBA
  • Granular user permissions for purchasing managers and ops teams

real moats

  • Robust integration with Amazon SP-API and historical report aggregation
  • Operational lock-in across supply chain, vendor management, and purchasing teams
  • Refined algorithms for handling stockout padding and non-linear lead times
