Vendor, buyer, and admin permissions overlap in ways that generic role systems cannot handle cleanly, risking one vendor seeing another's data.
Marketplaces & Platforms
Marketplaces & Platforms Laravel Development
Marketplace backends need clean ownership between three sides: buyer, vendor, and platform. We calculate commission at sale time (not payout time), so refunds and disputes don't break your books.
What we get right by default
- Commission calculated at sale time, adjusted on refund
- Vendor payout scheduling with new-seller holds
- Moderation queue with full status history
- Platform APIs for partner and integration access
How we think about it
Where Marketplaces & Platforms projects actually break
The recurring mistake in marketplace backends is calculating commission at payout time instead of sale time: it works fine until a refund or partial return happens after a payout has already gone out, and now the numbers don't reconcile. We calculate and record commission the moment a sale completes, and build payout runs as a separate, later step that respects a hold period, so a refund within that window adjusts the payout before it happens rather than requiring a manual clawback after.
Vendor, buyer, and admin permissions overlap in ways a generic role system doesn't handle well: a vendor should manage their own listings but never see another vendor's data, while an admin needs oversight across everyone. We build this as scoped permissions from the start. Moderation (listing approval, dispute handling, abuse reports) runs through an explicit queue with full status history, so there's a clear record of who approved, rejected, or escalated what, which matters as much for internal accountability as for handling a dispute later.
Where projects go wrong
Common Marketplaces & Platforms backend challenges
Commission, refund, and payout logic must stay traceable or marketplace finance becomes difficult to reconcile once disputes and partial refunds enter the picture.
Moderation workflows need clear queues, status changes, audit logs, and admin visibility, not an inbox of flagged items nobody owns.
Platform APIs for partner integrations need proper scoping and rate limiting so one partner's misbehaving integration can't degrade the platform for everyone else.
What we build
Systems we build for Marketplaces & Platforms
Vendor and buyer dashboards
Separate, properly scoped workflows for sellers, customers, staff, and platform admins, so no one can see data outside their own scope.
Commission and payout systems
Fee calculation recorded at sale time, refund-aware payout scheduling with holds, and full transaction logs for reconciliation.
Moderation tools
Listing approval queues, dispute handling with status history, and abuse reports with clear ownership and escalation paths.
Platform APIs
REST endpoints for web, mobile, and partner integrations, with scoped tokens and rate limiting so no single integration can degrade the platform.

FAQ
Marketplaces & Platforms project questions
How do you calculate commission when there's a partial refund?
Commission is recorded at sale time against the original amount, and a refund (partial or full) creates an adjusting entry rather than mutating the original record, so the full history stays auditable.
Can vendors have their own subdomain or storefront?
Yes, this is a common pattern; we build vendor-scoped storefronts or subdomains as part of the multi-tenant routing layer.
Do you handle payout holds for new vendors?
Yes. Payout scheduling supports configurable hold periods (common for new or high-risk vendors) before funds are released.
Can you build dispute resolution between buyers and sellers?
Yes, as a structured workflow (dispute opened, evidence submitted, resolution, and if needed, refund or payout adjustment) rather than an unstructured support ticket.
