How does AI categorization work?

The AI model analyzes transaction merchant name, amount, and date against historical patterns to predict the spending category. Predictions are shown to users who can accept or correct them. Corrections train the model to improve accuracy for similar future transactions.

How is the financial health score calculated?

The score (0-100) combines: emergency fund ratio (months of expenses saved), debt-to-income ratio, budget adherence (spending within budget), savings rate (percentage of income saved), and credit utilization. Each factor contributes a weighted score with a benchmark range.

How are savings goals tracked?

Users create goals with a name, target amount, and target date. Linked to a savings account, the current balance shows goal progress. The system projects the expected completion date based on the current savings rate and alerts the user if they're off track to meet their target date.

The Challenge

Why building a Budgeting from scratch is hard

Building a Personal Finance & Budgeting Platform from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing budgeting-specific business logic, integrations, and role-based access rules.

What's Included

Everything your Budgeting needs

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

Bank account aggregation with transaction sync

AI-powered transaction categorization

Monthly budget creation with spending limits per category

Bill tracking with due date reminders

Spending analytics with trend charts and peer comparison

Savings goal tracking with projected timelines

Net worth dashboard: assets, liabilities, and net worth

Financial health score with improvement recommendations

Architecture

How it's built

The generated Budgeting follows production-grade architecture patterns.

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

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

PostgreSQL relational schema with normalized tables for all budgeting entities

JWT + Google OAuth authentication with granular permission gates per role

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

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

Database

PostgreSQL schema designed for Budgeting

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.

accounts (id, user_id, institution, account_type, balance, last_synced_at, plaid_access_token, workspace_id)
transactions (id, account_id, date, amount, description, category, subcategory, is_pending, notes, is_excluded)
budgets (id, user_id, month, year, categories jsonb, total_income, total_budgeted, total_spent)
savings_goals (id, user_id, name, target_amount, current_amount, target_date, color, status)

FAQ

Common questions about building a Budgeting

Users connect their bank via Plaid's Link modal, which authenticates directly with the bank without sharing credentials with the app. Plaid returns an access token the platform uses to fetch transactions and account balances. Connection stays live until the user revokes it.
