Auditing for T&E

Real-time AI expense auditing vs. legacy analytics tools and human audit services

Stop using rigid, one-size-fits-all expense audit tools. AppZen’s flexible AI adapts to your unique policies with customizable workflows, while Oversight, BPO and manual audits, and inflexible legacy systems make you change to fit their limitations.

Why companies are switching from Oversight

Discover how AppZen’s expense auditing capabilities compare to Oversight, manual audits, and BPO services' reactive, post-payment approach across key features, including AI, customization, compliance, and automation.

Functionality

AppZen Expense Audit

Oversight

Manual audits & BPO

T&E expense auditing

Review and validate employee travel and expense claims for policy compliance

NextGen AI-powered, real-time expense auditing that automatically audits 100% of expenses prepayment, detecting fraud and policy violations, while boosting productivity and minimizing errors/waste
Legacy analytics tool with Google-based OCR that relies on third-party statistical models and is typically performed post-payment, to ensure compliance with company policies and prevent fraud or abuse
Dependent on human auditors, these services are time-intensive, costly, and typically review only a fraction of expenses, leading to lower audit coverage and inconsistent enforcement

AI audit models

Automatically check expenses against company policies

40+ out-of-the-box best practice, customizable T&E audit models
Limited out-of-the-box AI models with limited configurability
Human-based audit rules and processes with limited capability for customisation

Analytics & reporting

View spending reports and identify trends

Dynamic, AI-Powered analytics, delivering real-time, contextual insights into spend behavior, risk exposure, and policy adherence
Standard out-of-the-box reports with behavioral trends, typically post-payment reporting
Standard reporting packages with human analysis but limited real-time insights and customization options

Adapt to unique expense policies

Create and configure AI models to match your distinct regulations, policies and business processes

Create AI audit models and configure existing best practices models to meet complex processes and global requirements without IT debt, eliminating false positives while scaling effortlessly
Limited customization options that generate a high number of false positives, requiring extensive manual reviews and technical resources
Human services are customisable but require auditor retraining and often incur additional costs

Global compliance and multi-language support

Handle international regulations and foreign receipts

Built-in compliance models for HCP, Anti-Bribery, VAT, and regional regulations with AI-powered translation in 40+ languages to detect policy violations in foreign receipts
Limited compliance coverage and lack of regulatory compliance models, with limited built-in translation capabilities
Regional expertise with multilingual staff, but inconsistent coverage and higher costs for global operations.

Auto-approval rates

Speed up reimbursements with automated processing

Achieve 75%+ pre-payment auto-approval rates with context-aware AI, leading to faster processing times
Limited pre-payment auto-approval functionality, mainly works in post-payment
Manual approval processes with limited automation capabilities result in slower processing times.

Receipt understanding

Extract and verify information from receipt images

Deep contextual understanding of receipt line items, nuances, and types, like differences between alcohol brands, types of food, fair pricing, or venue/merchant category
Basic pattern recognition and anomaly detection, relying on exact keyword search to identify items on a receipt
Human reviewers can understand context but lack scalability and consistency across high transaction volumes

AI-generated fraudulent receipt detection

Identify suspicious or fraudulent expense documents

Multi-layered AI models trained on millions of receipts to detect ChatGPT generated & GenAI created fake receipts and deep fakes
Basic pattern matching that AI-generated fraudulent receipts can easily fool
Relies on human expertise to identify suspicious receipts but may miss sophisticated AI-generated forgeries

Expense approval workflows

Set up custom approval processes for different expense types

Self-service DIY Smart Workflows for intelligent risk-based manager approvals built in minutes without IT support
No DIY capabilities with basic approval workflows requiring technical resources and manual intervention for any workflow customization
No self-service capabilities - all workflow changes require service provider involvement and additional fees

Digital workforce

AI agents that automate routine expense processing tasks

AI Agents automate 95% of expense auditing tasks, achieving 90% compliance rates and 40-50% workload reduction while transforming manual processes into intelligent automation
No AI Agent capabilities — relies on traditional manual processes and basic rule-based automation without intelligent decision-making
Human agents provide personalized service, but cannot scale to handle thousands of transactions simultaneously

Slack and Microsoft Teams integration

Handle approvals within your existing chat tools

Native Slack and Microsoft Teams integration enables faster approvals directly within communication tools, streamlining workflows and reducing approval delays
No Slack or Microsoft Teams integration - approvals must be done through separate systems, creating workflow friction
No native integration with communication tools; approvals are handled through separate BPO systems and processes

Expense management system support & deployment

Connect with your current expense management software

Seamlessly integrates with all major EMS platforms, including SAP Concur, Oracle, and Workday. Hosted on AWS with deployment options in both the EU and US for greater flexibility
Primarily built for SAP Concur with some support for other EMS and ERP systems. US-only hosting primarily; limited EU data hosting capability and deployments
Integration and deployment capabilities vary based on provider and BPO setup, limiting flexibility and geographic control

Global scope & security certifications

Enterprise security
and global compliance standards

Proven global deployments with support for country-specific requirements (e.g., Fapiao in China). Fully compliant with ISO 27001, GDPR, SOC 1 & 2 Type II, PCI DSS, HIPAA, and the EU AI Act
Limited global coverage with partial certification. Lacks SOC 1 compliance and unclear adherence to international AI regulations
Narrow support for global requirements; compliance certifications vary by solution and geography, leading to inconsistent coverage
