BPMS & ERP Platform (Modular, Workflow-Driven)

What It Is A modular BPMS + ERP stack that unifies core operations (Inventory, HR/Attendance, Finance) with a workflow engine (BPMN) for approvals, SLAs, and auditable processes. Designed for staged rollout, multi-tenant setups, and real-time dashboards. --- Core Modules - Inventory & Stock — SKUs, batches, locations, QR/Barcode moves, cycle counts - HR & Attendance — shifts, leave, timesheets, biometric/device integrations - Finance & Billing — invoices, payments, cost centers, export to accounting - Procurement & Sales — RFQs/POs/SOs, vendor/customer management - Workflow (BPMS) — BPMN-driven approvals, tasks, escalations, SLAs, audit trail - Reporting — KPI dashboards, PDF/Excel exports, scheduled emails/webhooks --- Architecture - Frontend: Next.js (App Router), React 18, TypeScript, Tailwind, PWA, SSR/SSG/ISR - Backend: Node.js + NestJS/Fastify (typed DTOs, DI, modular), REST/GraphQL/tRPC - Workflow/BPMS: Camunda/Zeebe or Temporal for long-running, reliable workflows - Data: PostgreSQL (+ Prisma), Redis (cache/locks/queues), S3-compatible object storage - Messaging/Jobs: BullMQ (job queues), Redis Streams / Kafka for event pipelines - Realtime: WebSocket/SSE channels for live tables, notifications, approvals - Auth & Security: Auth.js/Keycloak (OIDC), RBAC/ABAC, JWT rotation, per-tenant scoping - Files & Docs: S3 uploads, server-side PDF generation, signed URLs - Observability: OpenTelemetry traces, Sentry (errors), Prometheus + Grafana (metrics) - DevOps: Dockerized services, GitHub Actions CI/CD, preview deploys, zero-downtime releases - Edge & Delivery: Vercel/Cloudflare for global routing, CDN, image optimization --- QR/Barcode & Devices - QR/Barcode for stock moves, picking/packing, asset tags - Web Scanner (ZXing/jsQR) on mobile PWA — no native app needed - Label Printing (ZPL/PDF) with batch templates and reprint history --- AI-Assist (Optional) - LLM copilots for search (“find POs awaiting approval”), anomaly hints, and summaries - RAG on your operational data for natural-language analytics - Agents that propose next steps (e.g., auto-creating a replenishment PO) --- Governance & Compliance - Multi-tenant isolation, row-level security patterns - Audit trails, signature logs, immutable event history - Data retention policies, backup/restore runs, DR plans --- Why It Wins - Incremental rollout (module by module) with zero vendor lock-in - Visible ROI — faster approvals, fewer errors, real-time stock truth - Admin-friendly — schema-driven forms, role-based views, self-serve reports
