Supply Chain Backend

Supply Chain App Backend Template
Track Raw Materials and Score Vendor Performance

Q: What is a supply chain backend?

A supply chain backend is a BaaS schema and API for managing raw materials, vendors, shipments, and inventory.

Q: What does the Supply Chain template include?

It includes Raw Material (name, quantity, location), Vendor (name, performance score), Shipment (material, vendor, status), Inventory (material, level), ER diagram, API playground, and an AI Agent prompt.

Q: Why use Back4app for a supply chain app?

Back4app provides managed database, auth, real-time queries, and flexible schema so you can ship operational efficiency and supplier management without running your own backend.

Q: How do I run queries for materials and vendors with Flutter?

Use the Raw Material and Vendor classes to query and display data and performance scores, leveraging the Back4app SDK.

Q: How do I manage shipments with Next.js server actions?

Use a server action to create a Parse Object for Shipment with material and vendor pointers and status. Optionally validate in Cloud Code.

Q: Can React Native cache materials and vendors offline?

Yes. Enable Local Datastore and pin Raw Material and Vendor results so users can browse saved data without connectivity.

Q: How do I prevent duplicate shipments?

In Cloud Code beforeSave for Shipment, query existing shipments and reject if a duplicate exists.

Q: What is the best way to show raw materials and vendors on Android?

Query Raw Material and Vendor classes to display data and performance scores, using the Back4app SDK for data management.

Q: How does the inventory update flow work end-to-end?

Users can update inventory levels, and the system updates in real-time using Live Queries for instant notifications.

A production-ready supply chain backend on Back4app with raw material tracking and vendor performance scoring. Includes ER diagram, data dictionary, JSON schema, API playground, and an AI Agent prompt for rapid bootstrap.

Overview

A supply chain product needs raw material tracking, vendor performance scoring, inventory management, and logistics.

This template defines Raw Material, Vendor, Shipment, and Inventory with real-time features and ownership rules so teams can implement supply chain operations quickly.

Core Supply Chain Features

Every technology card in this hub uses the same supply chain backend schema with Raw Material, Vendor, Shipment, and Inventory.

Raw material tracking

Raw Material class stores name, quantity, and location.

Vendor performance scoring

Vendor class links name and performance score.

Shipment management

Shipment class stores material reference, vendor, and status.

Inventory control

Inventory class tracks material levels and locations.

Real-time updates

Enable real-time updates for inventory and vendor alerts.

Why Build Your Supply Chain Backend with Back4app?

Back4app gives you raw material, vendor, shipment, and inventory primitives so your team can focus on operational efficiency and supplier management instead of infrastructure.

•Material and vendor management: Raw Material class with tracking fields and Vendor class for performance evaluation supports supply chain operations.
•Shipment and inventory features: Manage shipments with statuses and track inventory levels easily.
•Realtime + API flexibility: Use Live Queries for inventory updates while keeping REST and GraphQL available for every client.

Build and iterate on supply chain features quickly with one backend contract across all platforms.

Core Benefits

A supply chain backend that helps you iterate quickly without sacrificing structure.

Rapid supply chain launch

Start from a complete raw material and vendor schema rather than designing backend from zero.

Real-time inventory support

Leverage real-time updates and alerts for enhanced supply chain management.

Clear vendor evaluation flow

Manage vendor performance with scores and notifications for performance changes.

Scalable permission model

Use ACL/CLP so only authorized users can edit materials and vendor data, and manage shipments.

Inventory and shipment data

Store and aggregate inventory and shipment data for display and interaction without schema resets.

AI bootstrap workflow

Generate backend scaffolding and integration guidance fast with one structured prompt.

Build with AI Agent

Use the Back4app AI Agent to generate a real supply chain app from this template, including frontend, backend, auth, and raw material, vendor, shipment, and inventory flows.

Back4app AI Agent

Ready to build

Create a supply chain app backend on Back4app with this exact schema and behavior.

Schema:
1. Raw Material: name (String, required), quantity (Number, required), location (String, required); objectId, createdAt, updatedAt (system).
2. Vendor: name (String, required), performanceScore (Number, required); objectId, createdAt, updatedAt (system).
3. Shipment: material (Pointer to Raw Material, required), vendor (Pointer to Vendor, required), status (String, required); objectId, createdAt, updatedAt (system).
4. Inventory: material (Pointer to Raw Material, required), level (Number, required); objectId, createdAt, updatedAt (system).

Security:
- Only authorized users can update/delete material and vendor data. Use Cloud Code for validation.

Auth:
- Sign-up, login, logout.

Behavior:
- List materials, evaluate vendors, manage shipments, and update inventory.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for raw materials, vendors, shipments, and inventory.
