A cloud-hosted platform that runs the full operations of repair businesses and retail shops (point of sale, inventory, repair-ticket workflows, CRM, staff management, and billing) from a single multi-tenant codebase. Each business gets an isolated, subdomain-scoped workspace; a superadmin console onboards tenants, manages subscription plans, and applies industry-specific vertical templates (e.g. phone repair, mobile tyre fitting) that preconfigure catalogues, statuses, and pricing.
MULTI-TENANCY & ISOLATION
Subdomain-based tenant resolution with a middleware chain (auth → tenant → branch → RBAC → rate-limit). PostgreSQL Row-Level Security enforces per-business and per-branch data isolation at the database layer.
LAYERED BACKEND
~40 controller/service modules over the Next.js API layer, with business logic pushed into ~215 versioned SQL migrations and Postgres RPC functions for money-critical operations - profit & loss, split-tender reconciliation, refund sign handling, cash-movement ledgers.
STATE & DATA
TanStack Query for server-state caching and optimistic updates, Zustand for POS/session/UI stores, Supabase Realtime for live messaging and dashboard updates, Redis for rate limiting and hot-path caching.
Point of Sale
Register sessions with cash-drawer tracking, split-tender payments, refunds and exchanges, gift cards, store credits, trade-ins / buyback, loyalty points, HID barcode-scanner support, and live KPI dashboards.
Inventory
Product variants and attributes, bundles, suppliers and purchase orders (incl. auto-generation from low stock), supplier returns, stock counts, damage/returns, bin management, Excel bulk import/export, and batch barcode-label printing.
Repairs
Repair tickets with configurable statuses and drag-and-drop workflows, device/fault catalogues, technician assignment, estimates, warranty lookup, and vehicle records for automotive verticals.
Appointments & booking
Public booking widgets and an embeddable price/status tracker, availability engine, business hours, and blocked dates.
CRM & staff
Customer groups, custom fields, asset history and record merging; employee time clock, shifts, payroll, commission rules, IP whitelisting, PIN auth, activity logging, and role-based permissions.
Billing
Stripe checkout, customer portal, and webhooks driving tiered plans, custom-negotiated pricing, per-tenant module entitlements, plan-limit enforcement, and a nightly subscription-reconciliation cron.
Superadmin
Tenant onboarding, plan and module-template management, broadcasts, cross-tenant analytics, helpdesk, manual payments, and automated business backups.
- →Designed money-handling flows (split tender, partial refunds, trade-ins, deposits) so cash-drawer expectations and P&L stay correct across every payment path.
- →Built a configuration-driven module system letting each plan/tenant enable or hide entire feature areas without code branches.
- →Kept tenant isolation enforced at the database via RLS rather than trusting application code.
