→ Checkout paths are atomic against inventory.Reservation or decrement happens in a single transactional boundary. Failed payment releases stock predictably. Race conditions at flash-sale scale are treated as a first-class design problem.
7UNIT / E-COMMERCE
Multi-merchant commerce systems built foratomic checkout and ERP-connected inventory.
E-commerce looks like a storefront until peak traffic hits. Then it is inventory contention, payment webhooks, tax and fulfilment edge cases, and ERP drift. We build checkout and operations layers that stay consistent when concurrency and integrations matter.
7UNIT / WHAT WE BUILD
Headless or hybrid storefronts on React / Next.js. Cart and checkout flows with atomic inventory reservation — no oversell under load. Payment provider integration with webhook-driven reconciliation, not end-of-day guessing. Multi-merchant or multi-brand tenant models where each seller's data stays isolated. ERP- or OMS-connected catalog and stock via event-driven sync. WhatsApp-native order updates and support where the market expects chat-first commerce.
7UNIT / WHAT WE DO NOT TAKE ON
We do not run performance marketing, SEO retainers, or creative production. We do not promise conversion-rate outcomes. We build the commerce engine, integrations, and operational reliability — your growth team owns acquisition.
7UNIT / KEY ENGINEERING DECISIONS
→ Reconciliation follows payment truth, not batch hope.Webhook-confirmed settlement drives internal order state. Discrepancies surface as exceptions with correlation IDs — not silent drift.
→ ERP or OMS is the operational source of truth when you say it is.Event-driven sync from Odoo, custom OMS, or warehouse APIs. The storefront reflects operational reality; manual spreadsheet bridges are not the long-term design.
→ Tenant isolation for marketplaces.Each merchant's catalog, orders, and payouts are scoped at the data layer. Marketplace operators see aggregate dashboards without accidental cross-merchant data leakage.
