AuditXpenser – Complete CA Audit & MSME

Compliance Platform

1. Executive Summary

AuditXpenser is a comprehensive CA Audit & Compliance Platform designed to streamline the entire

statutory audit lifecycle. It enables Chartered Accountants to manage client audits from data collection to

final working paper preparation through a single integrated application.

Unlike traditional audit tools that focus only on expense verification, AuditXpenser combines:

Expense Audit

GST/TDS/RCM Review

Bill Matching

Fixed Asset Audit

Form 3CD Support

Client Query Management

Working Paper Generation

The platform's biggest advancement is its API-based integration with MSME Guard, allowing auditors to

perform MSME compliance review—including Section 43B(h), MSMED Interest, Clause 22, Clause 26(A), and

MCA MSME-1 readiness—within the same audit dashboard.

As a result, AuditXpenser functions as a Complete CA Audit & Compliance Platform, significantly reducing

manual effort while improving audit quality and visibility.

2. Business Problem

Traditional audit engagements require CAs to work across multiple disconnected tools and spreadsheets.

Typical workflow includes:

Expense verification in Excel

Bill matching manually

GST reconciliation separately

TDS verification independently

Fixed asset schedules in separate files

Form 3CD preparation manually

Client queries through Word/Email

MSME compliance using Tally and additional calculations
