Commerza

A commerce SaaS for Bangladeshi small businesses: storefront, point of sale, inventory with FIFO and gross-average costing, branches and warehouses, local couriers, server-side tracking, and a unified Messenger, Instagram and WhatsApp inbox with an assistant. It is in active build — the dashboard and backend foundations are in place.

Pricing, online store with each tenant on its own domain, point of sale with tills, local browser storage and receipt printing, inventory and goods received, orders that ship in parts, courier integrations (Steadfast, Pathao, RedX and others), payment gateways (bKash, SSLCommerz and others), server-side Meta, GA4 and TikTok conversion events, Meta ads management with true return on ad spend beside orders, and a shared inbox whose assistant answers from read-only tools, hands off to people and drafts replies behind a confidence gate. The assistant's model provider is pluggable and not yet attached.

Seven independent services with fixed boundaries: a FastAPI backend (main API, storefront API, socket service, Taskiq worker and scheduler) holding most of the product in engines, a Next.js dashboard and site, a Go storefront edge, and Go services for Accounts (the only place anyone signs in), Ads, Analytics and Chats, each with its own database. Integrations (couriers, payments, Meta) are one file each and only translate; business rules stay in engines. A virtual Meta that answers Graph calls from Redis lets the whole product run locally. Every service has its own rules file.
