Expense management software 101

Expense management is part of every finance team’s job, but it’s rarely the part they want to spend time on. The work is often manual, fragmented and time-consuming.

Chasing receipts, correcting expense reports and cleaning up transactions at month-end: this is still how many organizations manage spending. The work gets done, but it’s slow and hard to control, especially as the business grows.

Corporate expense management software is designed to change that. This guide breaks down how it works, what to look for and how to choose the right platform.

What is expense management software?

Expense management software is a system that helps organizations track and manage business spending across employees and vendors.

Depending on the platform, this may include managing reimbursements, company-issued cards or a combination of both, with varying levels of control and automation. Modern systems bring these workflows into a centralized platform, replacing disconnected processes like spreadsheets and email.

At a high level, expense management software enables finance teams to:

• Document business expenses
  Capture transactions, collect receipts and maintain documentation in one place
• Apply policies and approval workflows
  Review, approve and guide spending based on company policies, with varying levels of enforcement depending on the platform
• Support reconciliation and reporting
  Provide a clear view of organization-wide spending, making it easier to monitor activity and identify issues 

That foundation looks similar across platforms, but how each system captures, processes and presents expense data can vary significantly. The differences become clearer when you look at how modern platforms handle key parts of the workflow. 

Key features to look for in expense management software

Automated receipt capture and OCR

Manual receipt submission slows down expense reporting and often leaves gaps in documentation. Automated receipt capture tools collect and store receipts as expenses occur, reducing the need for follow-up. OCR (optical character recognition) then extracts key data from those receipts and matches it to transactions, keeping records complete and structured. This improves accuracy and eliminates one of the most time-consuming parts of expense management. 

Policy enforcement and approval workflows

Applying policies after expenses increases the risk of fraud and overspending. Expense management software supports policy-driven workflows that guide approvals and flag issues before they move forward. These workflows can include setting limits by merchant category or dollar amount, as well as requiring approvals for certain types of spend, ensuring expenses align with company guidelines without manual review. 

Real-time spending visibility and reporting

Relying on historical expense data forces finance teams to make decisions based on outdated information. As transactions are captured and processed in real time, modern platforms continuously update spend data, providing a current view across teams and projects. With up-to-date information available as activity occurs, finance teams can monitor budgets, identify issues earlier and course-correct before problems escalate.

Corporate cards: Prepaid, charge and virtual cards

Employees bear the burden when using personal cards for business expenses, paying out of pocket, tracking receipts and waiting to be reimbursed. Finance teams don’t see those transactions until after expense reports are submitted. 

Platforms that offer corporate charge cards, virtual cards and prepaid cards are central to expense management software, allowing organizations to manage purchases directly as they happen. Transactions are captured in real time and controls can be applied to how and where money is spent, giving finance teams more visibility while simplifying the experience for employees.

Bill pay

Vendor payments are often managed across multiple systems, with invoices tracked in one place, approvals handled over email and payments processed separately. Finance teams must coordinate across tools and piece together payment status manually. Some expense management platforms include bill pay functionality that brings vendor payments and employee spend into the same platform, allowing teams to track all outgoing funds in one place.

Expense reimbursement processing

Reimbursement workflows are often managed separately from other expense processes, creating another disconnected workflow for finance teams to track and manage. Expense management software streamlines this process by centralizing submission, approval and documentation of reimbursements with standard expense workflows. This reduces processing time and helps ensure expenses are handled more consistently.

Accounting and ERP integrations

Manually transferring expense data into accounting systems often means hours spent uploading files and fixing errors. Small issues can turn into time-consuming rework, especially during close. Many expense management platforms integrate directly with accounting and ERP systems to sync transaction data automatically, reducing manual effort and helping keep financial records accurate and up to date.

Travel and expense management

When employees book travel in one system and pay in another, finance teams have to piece together transactions and documentation, with limited context into what was spent and why. Some expense management platforms include travel and expense capabilities that connect booking, payments and expense tracking in a single workflow, helping teams maintain visibility into travel spend and reduce the need to reconcile disconnected data.

Mobile expense submission

Tracking paper receipts while traveling and waiting to submit expenses from home often leads to lost or misplaced receipts. Finance teams are left following up to fill in gaps. Mobile tools allow employees to capture receipts and submit expenses as they occur, without waiting until the end of a trip or reporting period. This keeps data current and reduces follow-up for both employees and finance teams.

Security and compliance standards

When expense data is managed through email and spreadsheets, gaps in documentation, errors and data breaches are all more likely. This makes it harder to maintain compliance and increases audit and fraud risk. Expense management platforms centralize data, apply standardized controls and maintain complete records, helping organizations support compliance as spending occurs.

How the typical expense reimbursement workflow works

Without many of the features described above, finance teams are left relying on reimbursement workflows to manage employee spending. While familiar, this approach creates delays, manual work and limited visibility for finance teams, while also adding friction for employees.

In a typical reimbursement process:

• Employees pay out of pocket
  Business expenses are covered using personal funds, which can create financial strain, especially for frequent or high-cost purchases. At the same time, finance teams have no visibility into spending until after it occurs.
• Receipts are submitted after purchases happen
  Employees are expected to track and upload receipts while managing their day-to-day responsibilities. Receipts are often lost or delayed, leading to follow-up and stress for employees, and incomplete or inconsistent documentation for finance.
• Managers review and approve expenses
  Expense reports are reviewed manually, which slows approvals and creates back-and-forth when information is missing. This adds administrative overhead and delays reimbursement timelines.
• Finance processes and reconciles transactions
  Finance teams verify, code and enter expense data after the transaction is complete, often chasing down details to fill gaps. This creates additional manual effort and increases the risk of errors.

Because this process happens after spending occurs, finance teams are left correcting activity instead of controlling it, while employees wait to be reimbursed through a process that can feel slow and unpredictable.

What changes with expense management software? From manual to modern 

The differences between manual processes and modern expense management become clearer when you compare each approach. 

The role of AI and automation in modern expense management

AI and automation are changing when and how expense work gets done. Instead of reviewing and correcting transactions after the fact, finance teams are working with systems that capture, process and structure expense data as it happens.

This shift changes how finance teams operate in a few key ways:

• Less manual work, faster workflows
  Tasks that once required follow-up, like collecting receipts or matching transactions, now happen automatically. What used to take hours or days is handled in seconds, reducing the amount of manual effort across the entire process. Automated receipt matching is one example, eliminating the need to chase down documentation.
• Improved accuracy and consistency
  Instead of relying on individuals to review and code each transaction, systems apply consistent rules and logic across all spend. This reduces errors and ensures expenses are categorized the same way every time.
• Predictive, data-driven categorization
  Systems learn from past transactions to suggest or apply coding automatically, reducing guesswork and standardizing how expenses are recorded over time. AI-powered GL coding, for example, helps teams maintain consistency without manual review. 
• Real-time visibility into spend
  Because data is captured and processed immediately, finance teams no longer have to wait until month-end to understand what’s happening. Spend can be monitored as it occurs, not after reports are submitted.

As more of the work shifts from people to systems, expense management becomes faster, more consistent and easier to control in real time. These changes become easier to see in practice.

Expense management use cases

Expense management looks different across organizations, but the underlying challenges are often the same. These examples show how teams apply PEX’s capabilities in real-world scenarios. 

Shannon Staley & Sons

As the business grew, managing job site spending became much harder. With only two cards shared across seven project managers, the team spent hours driving across Pittsburgh just to hand them off. With PEX, the Shannon Staley & Sons team issued individual cards with built-in spend controls and used the mobile app to capture and tag receipts in real time. This eliminated receipt chasing and gave leadership accurate, up-to-date cost data.

Result: 50+ hours saved per week and improved job cost visibility.

Eastshore Alliance FC

Expense reports were managed through emailed receipts, shared folders and Google Sheets, with hours spent sorting transactions and entering data by hand. Coaches also had to cover travel expenses out of pocket and wait to be reimbursed. 

After evaluating both Ramp and PEX, Eastshore Alliance chose PEX for its ability to integrate directly with SAP Concur and support a more structured workflow. With flexible card options like the PEX Visa® Commercial Card, transactions sync automatically into their existing systems, eliminating manual entry and reimbursement delays.

Result: 10 hours saved per month and zero out-of-pocket travel costs.

Cypressbrook Multifamily Management

Before automation, reconciliation meant reading through managers’ notes, re-entering GL codes and waiting on missing receipts, pushing month-end close two to three months late. With PEX, Cypressbrook uses AI-powered GL-coding suggestions and automated enforcement tools to keep transactions accurate and complete in real time. This reduced manual coding and ensured expenses were fully documented before close.

Result: 5 hours saved per month and month-end close completed on time.

Instant visibility and ease of use show up in daily workflows as well. One reviewer noted that “the real-time visibility aids in budget forecasting,” while another highlighted how PEX “codes each expense to different jobs correctly,” reducing manual effort and improving accuracy. 

Top 5 best expense management software compared

The best-fit expense management platform depends on how your organization manages spend today and how that complexity is expected to grow. This comparison highlights how leading platforms differ. 

Picking the right platform ultimately comes down to how well it meets your organization’s specific needs.

Choosing the right expense management software for your business

It’s critical to choose a system that can grow with the business. Finance leaders should focus on answering a few key questions during their evaluation:

• Can the platform support more transactions, users and entities without adding operational complexity or manual effort?
• Does the system enforce policies in real time and provide a complete audit trail for every transaction?
• Can spend policies, approval workflows and payment methods adapt as the business evolves?
• Will finance teams have access to current, real-time spend data, or only historical reports after the fact?
• Beyond surface-level savings, does the platform free up time for higher-value finance activities?

The right solution balances today’s needs with future growth, helping finance teams maintain control and efficiency as operations scale.

What is the best expense management platform?

Across use cases and industries, three factors consistently separate tools that support growth from those that create more work: scalability, flexibility and control. PEX is designed to deliver on each of these as organizations manage more complex, distributed spend. 

Scalability

As organizations grow, transaction volume, team size and operational complexity increase. PEX supports that growth with flexible card options, including the PEX Visa® Commercial Card.  Automated receipt capture and coding and accounting integrations reduce manual steps, allowing finance teams to manage more spend without expanding headcount.

Flexibility

Expense workflows vary across teams, projects and business models. PEX adapts to different types of spend with configurable cards, customizable controls and workflows that support everything from project-based purchasing to travel and vendor payments.

Control

Visibility alone isn’t enough. Finance teams need the ability to guide and enforce how money is spent. PEX applies controls at the point of purchase, with spend limits, category restrictions and real-time transaction visibility that help prevent issues before they happen.

By combining these capabilities in a single platform, PEX helps finance teams manage increasing spend with confidence. Book a demo to see how PEX helps finance teams control spend in real time and simplify expense management as they grow.
