Marketplace architecture
Vendor or seller accounts with isolated inventory, order visibility and role-based access, built the way a multi-vendor platform actually needs it structured.

E-commerce & Marketplace Development
A marketplace is not a themed store — it is vendors, inventory, orders and money moving between parties who do not trust each other by default. I build that structure in React and Django rather than forcing it through a template store builder.

Sound familiar?
- Multiple vendors or sellers need isolated inventory, orders and payouts, and a template store cannot model that
- Payment integration was bolted on, so refunds, webhooks and failed payments fail silently
- Stock, orders and fulfilment status live in someone's head instead of the system
- Regional payment methods (JazzCash and similar) are not supported by the platform you started with
Tell me whether you are selling one catalog or running a multi-vendor marketplace — the architecture is different from day one.
What you get
Concrete deliverables, not a retainer with vague scope.
Catalog and inventory
Product structures, stock tracking and order-to-inventory sync so what is shown as available is actually available.
Payment gateway integration
Stripe and regional providers such as JazzCash, covering checkout, webhooks, refunds and reconciliation.
Order and fulfilment tracking
Order status, history and admin visibility from checkout through delivery or completion.
Subscription and recurring billing
Plans, trials and usage limits wired to a payment provider where the product is billed on a recurring basis rather than sold per order.
Admin analytics dashboard
Sales, vendor and order reporting so the numbers are answerable without a database query.
How it runs
- Step 1
Vendor and order model
How sellers, inventory, orders and money actually move, mapped before any checkout screen exists.
- Step 2
Catalog and inventory
Product structures and stock tracking built around the real data, not a generic product schema.
- Step 3
Checkout and payments
Gateway integration with the failure paths — declined payments, webhooks, refunds — handled deliberately, not left as an afterthought.
- Step 4
Admin and reporting
The order, vendor and sales visibility an operator needs from day one.
- Step 5
Hardening and launch
Load-sensitive paths, error handling and a deployment path that is repeatable.

Read case studyE-commerce & Marketplace — questions
Do you build online stores on Shopify or WooCommerce?+
No — I build custom e-commerce and marketplace platforms in React and Django for businesses that have outgrown what a template store can model: multiple vendors, custom inventory rules, or a checkout flow that needs to do more than a standard cart.
Can you build a multi-vendor marketplace?+
Yes. Phamanovix, a multi-tenant marketplace I built for my own software brand, handles multiple vendors, inventory, order tracking and payment integration in production.
Do you integrate Stripe and regional payment gateways?+
Yes, including Stripe and regional providers such as JazzCash, covering checkout, subscriptions, webhooks, refunds and reconciliation — this is also core to my API integration work.
Do you handle subscription or recurring billing instead of one-off orders?+
Yes. CallLoom Dashboard runs Stripe subscription billing with plans, trials and webhook-driven state changes, which is the same pattern I bring to a recurring-revenue product.
