our call
Start with Sello — highest vibe code, weakest moat.
Mirakl
While a basic multi-vendor cart router and seller portal can be built in weeks using modern frameworks, replacing Mirakl at enterprise scale is impractical. Mirakl's value lies in its global seller network (Mirakl Connect), complex multi-region tax and ledger compliance, and deep integrations with legacy enterprise ERPs.

- Seller onboarding portal and basic profile management.
- Catalog offer mapping and inventory update REST/GraphQL APIs.
- Multi-vendor cart split-routing logic and order notification webhooks.
- Basic seller commission calculation and ledger tracking.

Sello
Syncing inventory to one single marketplace via custom code is straightforward. However, maintaining dozens of custom API adapters for regional European channels with shifting taxonomies and auth specs is an unmaintainable sink of dev time.

- Basic CSV/XML product feed generation
- Centralized order status view
- Channel-specific price markup rules
what you lose
