The Situation
Sellers, buyers, and ops were looking at different versions of the marketplace.
Duplicated listings, stock drift, and inconsistent delivery promises made the platform harder to trust as seller and buyer activity increased.

Was Outrunning Catalog Control.
We Centralized the Truth.
A growing marketplace needed seller onboarding, catalog, checkout, buyer apps, and operations tooling to share one inventory and order model.

Rating

Average post-launch app rating
Catalog data duplicated
Sellers repeated listing work and product truth drifted between surfaces.
Stock levels diverged
Inventory updates did not consistently reach every channel where buyers made decisions.
Checkout needed split payouts
Marketplace payments required clean order orchestration and seller settlement paths.
Operations needed better controls
Disputes, compliance checks, and SLA tracking needed a shared admin console.
The Real Cost
The real cost was buyer confidence being eroded by operational inconsistency.
When catalog and stock are not centralized, every new sales channel increases the chance of a broken promise.
Seller onboarding friction slows supply growth and makes quality control harder to enforce.
Operations teams cannot resolve disputes quickly if order state and payout context are split across tools.
What We Did
We made APIs the center of catalog, inventory, and order state.
We centralized catalog, inventory, and order state behind explicit APIs, then built vendor onboarding and compliance checks, unified checkout with split payouts, buyer iOS/Android apps, and an operations console for disputes and SLA tracking.
The work kept web storefront and mobile apps as consistent clients on top of shared marketplace logic.
The Result
The marketplace gained one catalog truth across web storefront and mobile buyer apps.

Client Feedback
Centralizing the catalog and order flow made the marketplace easier to operate. Sellers, buyers, and the operations team were no longer working from slightly different versions of the same information.

If catalog truth changes by channel, growth will create more operational cleanup instead of more leverage.
