Multi-Vendor E-commerce Platform

Client Context

The client is an enterprise-level e-commerce business launching a multi-vendor marketplace. Multiple independent vendors list inventory, receive sales alerts, and coordinate shipping.

Existing Environment

The company initially operated a basic single-vendor template site. When trying to scale to a multi-vendor system, they faced extreme performance bottlenecks and database lock errors during concurrency peaks.

Business Problem

Out-of-the-box templates failed to support vendor-specific shipping fee calculations, localized wallet checkout triggers (Nagad/bKash), and automated pdf invoice alerts for vendors, leading to operational chaos.

The Solution

Sigmatic Soft built a custom e-commerce engine using Laravel. The system integrates payment gateways, automatically calculates commissions, splits payouts, and syncs order status webhooks with local delivery providers.

System Architecture

Implementation

We designed a decoupled database layout, separating catalogs from active orders to avoid table locking. We built automated queue tasks that generate invoices and alert shipping systems as soon as payment callbacks are verified.

Operational Outcome

The custom engine operates with sub-second page loads. Payout distributions are calculated automatically, reducing manual bookkeeping work, and customers receive real-time package delivery alerts.

Lessons Learned

Multi-vendor platforms depend on database concurrency optimization. Separating transaction logs from the static products catalog table ensures search performance remains high during heavy sales events.
