our call
Start with Sellware — 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.
real moats
- Mirakl Connect ecosystem with pre-integrated catalogs of 10,000+ active enterprise sellers.
- Battle-tested edge case handling for complex B2B multi-entity tax, invoicing, and cross-border currency settlement.
- Deep enterprise pre-built connectors into SAP, Salesforce Commerce Cloud, Adobe Commerce (Magento), and Commercetools.

Sellware
Building a custom sync script for one store and one channel is easy, but scaling to multi-marketplace feeds means dealing with rigid developer verifications and constant API schema updates. You pay Sellware to handle Amazon SP-API token rot, rate limit backoffs, and marketplace categorization quirks.
you can rebuild
- Basic stock quantity sync across two connected platforms
- SKU-to-SKU mapping table and variant overrides
- Centralized order dashboard for viewing imported marketplace orders
- Basic pricing markup rules per channel (e.g., store price + 10% on eBay)
- Simple email notifications for failed sync runs
what you lose
- Pre-approved Amazon Selling Partner API (SP-API) app credentials and security audits
- Automated handling of rate limits, burst quotas, and exponential backoff across 5+ APIs
- Deep taxonomy and attribute mapping engines per marketplace category
- Real-time webhook queue architecture to prevent overselling during flash sales
- Vendor maintenance for constantly changing marketplace API specs and deprecations
real moats
- Amazon SP-API developer verification and strict PII compliance hurdles
- Massive integration surface area requiring continuous API maintenance
- High data switching cost once hundreds of complex multi-channel SKUs are mapped
