Web-Based Accounting System

The idea behind it.

Accounting Pro is a robust web accounting system designed to mirror high-end ERP capabilities in a streamlined dark-themed interface. It enforces double-entry discipline so journal entries cannot save unless debits and credits balance within a strict tolerance.

The product covers the full operational lifecycle: chart of accounts, accounts payable/receivable, tax mapping, FIFO inventory layers, payroll, fixed asset depreciation, and multi-currency translation into a base currency for a clean trial balance.

It ships with role-based access (Admin, Accountant, Viewer), invitation-only onboarding, rate-limited auth, audit logging, and a live demo deployment for hands-on evaluation.

What it does

• Mathematically enforced double-entry journal entries
• Chart of accounts, invoices, bills, customers, and vendors
• FIFO / moving-average inventory valuation
• Payroll, fixed assets, and depreciation workflows
• Tax groups, cost centers, stock, and warehouses
• Multi-currency invoices mapped into base currency
• RBAC: Admin, Accountant, Viewer
• Invitation-only onboarding with JWT email invites
• Audit service logging create / update / delete mutations
• Live demo deployment on Render

Where it fits

• Small businesses needing structured books without enterprise ERP cost
• Accountants managing AP/AR, payroll, and inventory in one system
• Startups validating multi-currency and inventory costing rules
• Teaching double-entry, trial balance, and year-end close mechanics

The challenges

• Keeping every posting balanced while supporting complex documents
• Implementing true FIFO cost layers that survive partial withdrawals
• Hardening auth, invites, and rate limits for a multi-user system

What I took away

• Accounting rules are product requirements, not optional polish
• RBAC and audit logs are essential once more than one role exists
• Multi-currency forces careful separation of document currency vs base currency
