our call
Start with SellerApp — 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.
you can rebuild
- 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.
- Admin operator dashboard for seller approval and product catalog moderation.
what you lose
- Access to Mirakl Connect network of 10,000+ pre-vetted enterprise suppliers.
- Pre-built enterprise integration connectors for SAP, Salesforce, and Commercetools.
- Automated multi-jurisdiction tax collection, DAC7/1099-K compliance, and legal seller onboarding frameworks.
- Proven infrastructure capability to handle millions of SKUs and extreme flash-sale concurrency.
- Dedicated enterprise support, seller operations support, and SLA guarantees.

SellerApp
Building a custom Amazon SP-API dashboard with basic rule-based PPC adjustments takes under two weeks with modern AI assistance. However, replicating SellerApp's multi-million keyword index, reverse ASIN lookups, and predictive bidding models requires significant backend infrastructure and data ingestion pipelines.

- Amazon SP-API sales, fee, and net profit reporting dashboard
- Target ACoS rule-based PPC bid automation (e.g., decrease bid if ACoS > 30%)
- Basic inventory velocity and restock notification alerts
- Search term performance reporting and negative keyword identification
- Listing optimization checklist and basic health monitoring
what you lose
- Proprietary historical search volume and keyword rank database across millions of ASINs
- Reverse ASIN lookup functionality for deep competitor keyword spying
- Algorithmic dynamic PPC bid optimization models based on machine learning
- Pre-vetted Amazon SP-API production developer credentials with elevated quota limits
- Multi-marketplace aggregation (e.g., Amazon + Walmart) within a single unified view
