Integrated Accounting System

Overview

The Integrated Accounting System (IAS) is a comprehensive double-entry accounting platform covering the full financial cycle — from day-to-day transactions to period-end reporting. It includes complete accounts receivable (estimates, invoices, payments, credit memos, sales receipts) and accounts payable (purchase orders, bills, bill payments, vendor credits, expenses, write checks) workflows, with banking reconciliation and 7 financial reports.

Core Modules

Accounts & General Ledger

Chart of accounts with full account types and sub-accounts. Journal entries enforce double-entry rules with debit/credit validation. Void entries with documented reasons and audit trail.

Invoicing & Receivables

Create invoices with line items and tax calculations, record full or partial payments, issue credit memos against invoices, and generate sales receipts for immediate transactions. AR Aging report tracks outstanding balances by customer.

Bills & Payables

Enter vendor bills with due dates and line items, process bill payments, issue vendor credits, and manage purchase orders from draft to received. AP Aging report tracks what you owe and when.

Estimates & Purchase Orders

Generate estimates for prospects with line items and expiry dates. Convert approved estimates to invoices. Create purchase orders for vendor procurement with status tracking.

Expenses & Write Checks

Track expenses with category and account assignment. Write checks with payee and memo tracking. Both modules automatically generate the corresponding journal entries.

Banking

Set up multiple bank accounts, track deposits and withdrawals, and reconcile against bank statements with transaction matching.

Customers, Vendors & Products

Maintain customer and vendor master data with addresses, payment terms, and transaction history. Product/service catalog with configurable tax rates applied to invoice and bill line items.

Security & Access Control

Role-based access control with built-in system roles (Admin, Accountant, Bookkeeper, HR, Viewer) and custom role creation. Permissions are granular — each module action (Read, Write, Delete, Void) can be individually granted or denied per role, with user-level overrides.

Audit Trail

Every create, update, delete, and void action is logged with user, timestamp, entity type, and action type. The audit log is immutable and filterable by date, user, and entity.

Financial Reports

Seven reports generated from live data with PDF export: Balance Sheet, Profit & Loss, Cash Flow Statement, Trial Balance, General Ledger, AP Aging, and AR Aging.
