You will get a custom ERP with inventory, invoicing, accounting, HR, CRM and AI


Project details
A custom ERP with inventory, invoicing, accounting, HR/payroll and CRM built on a product already live with paying customers, adapted to your business and deployed in weeks, not months.
I built and sell Logix Plus, a multi-tenant SaaS ERP live in production today. You start from a system that already works instead of paying six months to discover problems I have already solved.
ALREADY BUILT AND RUNNING
• Invoicing with PDF generation and payment tracking
• Barcode inventory, stock adjustments and low-stock alerts
• Customer and supplier ledgers with full history
• Double-entry accounting: chart of accounts, trial balance, P&L
• Bank and cash accounts with reconciliation
• Recurring expense automation
• HR and payroll
• CRM lead pipeline with communication logs
• Role-based permissions, multi-user access and audit logs
• AI: invoice scanning, natural-language queries, demand forecasting
• WhatsApp Cloud API automation
CUSTOMISED FOR YOU
Your branding and invoice design. Your currency, tax rules and numbering. Your roles, custom fields and reports. Take the modules you need, leave the rest.
Tell me how your business runs and I will tell you which modules and tier fit.

About Ahtsham
AI SaaS Developer | Next.js, Supabase & Stripe | Multi-Tenant, RAG
Faisalabad, Pakistan - 4:02 pm local time
I also built and commercially sell my own multi-tenant SaaS ERP, so I have made these architecture decisions with my own paying customers on the line, not just in client projects.
WHAT I BUILD
✔ Multi-Tenant SaaS Architecture: Next.js, React, Node.js, Supabase, PostgreSQL, MongoDB. Tenant isolation, row-level security, role-based access control, admin dashboards and database design, architected so customer #500 works exactly like customer #1.
✔ AI & LLM Features That Ship: OpenAI and Gemini wired into real workflows: RAG pipelines over your own documents, AI agents, vision-based document extraction, natural-language analytics and demand forecasting. Grounded outputs, cost-optimized model routing, production-grade, not a demo.
✔ Stripe Payments & Subscriptions: checkout, pricing tiers, webhooks, entitlement logic, usage limits and failed-payment handling, so access always matches what the customer actually paid for.
✔ MVP to Production Launch: half-finished, inherited or AI-generated codebases (Lovable, Bolt, Cursor, v0) audited, secured, refactored and made safe to put real users on. I extend the patterns that already work instead of rewriting your product.
✔ REST APIs, Dashboards & Integrations: JWT, Auth0 and Supabase Auth, Postman-documented endpoints, webhooks, third-party integrations, plus analytics views and admin panels your team can operate without calling a developer.
✔ Performance & Debugging: slow dashboards, N+1 queries, heavy re-renders, missing indexes and blocking API calls tracked down and fixed, with before/after numbers.
✔ Deployment & DevOps: Vercel, AWS, DigitalOcean, CI/CD pipelines, staging and production environments, audit logging and monitoring. You get a running product, not a ZIP file.
HOW I WORK
You get a reply within a few hours with how I would actually approach it: the architecture call, the risks I see and a realistic timeline. Not a template. If your project needs something simpler than what you are asking for, I will tell you that too.
