What costing methods are supported?

The generated app supports FIFO, LIFO, and weighted average costing. The costing method is set at the workspace level and applied consistently to all inventory valuation reports.

How do reorder alerts work?

When on-hand quantity plus incoming quantity falls below the reorder point for a SKU, the system alerts the purchasing team. Auto-PO generation creates a draft purchase order for the configured reorder quantity.

Can I track batches and serial numbers?

Yes. Products can be flagged for batch tracking (with expiry dates) or serial number tracking. Every movement records the batch or serial, enabling full traceability forward and backward.

The Challenge

Why building a Inventory from scratch is hard

Building a Inventory Management System from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing inventory-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Inventory needs

ProjectCode generates a production-ready Inventory with all the modules your team needs from day one.

Multi-location inventory tracking with transfers

Purchase order creation and goods receipt

Reorder point alerts with auto-PO generation option

Batch and serial number tracking

Product costing with FIFO/LIFO/average cost methods

Inventory valuation reports

Barcode label printing

Cycle count management with variance reporting

Architecture

How it's built

The generated Inventory follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for inventory workflows

NestJS REST API with dedicated inventory modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all inventory entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live inventory status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Inventory

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

products (id, sku, name, barcode, category_id, unit, cost_method, reorder_point, reorder_qty, workspace_id)
inventory_levels (id, product_id, location_id, qty_on_hand, qty_committed, qty_available, qty_incoming)
inventory_transactions (id, product_id, location_id, type, qty, reference_id, reference_type, cost, batch, serial, created_by, created_at)
locations (id, name, type, address, is_active, workspace_id)

FAQ

Common questions about building a Inventory

Each SKU has separate inventory levels per location. Transfers between locations create debit/credit transaction pairs that maintain a complete movement audit trail.
