Today’s tech-savvy CFOs track payables KPIs to measure processing costs and efficiency. How long does it take to pay invoices from the time they arrive? How fast is the approval process?

Accounts payable improvement can minimize data entry errors, late payments, and duplicate payments.

The following accounts payable (AP) process improvements helps you overcome these challenges and more to improve your payables KPIs — and your cash flow. 

Accounts payable process improvement tips

1. Decide on sweeping or incremental changes when setting expectations

Accounts payable process improvement is meant to serve you. It should remedy headaches, not create new ones.

Before committing yourself to accounts payable process improvement, have an idea of how far you want to take it. Setting expectations for what you want from the improvement process ensures you don't overwork yourself getting things done.

Taking this step can also save you time and money as you won't sink either into revamping something that you've already worked on improving.

Steps to take:

Before you start making changes, look at what the current and upcoming workload looks like.

For business with high seasonality, down periods give you the most leeway to make changes while still getting the rest of your work done.

If making changes is a high priority but you're entering a busy period, create a list of priorities that act as your compass.

When trying to figure out where to start, use an impact-effort matrix. This groups tasks by the time investment and overall impact of the change. This helps whittle down potential improvements to what's going to give you the highest return.

Pros Cons
Incremental Changes
  • The most approachable tactic
  • You learn about what you value as you go
  • Constantly adapting to any pain points that come up
  • Possibly sinking time into something that will change again
  • Changing one aspect might require changing another
  • Processes become inconsistent
Sweeping Changes
  • Make the time investment once
  • Gives the biggest efficiency gains
  • Solves multiple problems at once
  • New system may have learning curves to get up to speed
  • More of an upfront time investment
  • Hard to revert if you don't like the change

Pros and cons of incremental changes and sweeping changes to an accounts payable process

2. Automate your data entry to reduce input errors

Manual data entry is prone to errors. No matter how carefully your team works, no one is perfect.

Hopefully, the errors are small, without a significant impact on your cash flow, but they still need to be tracked down and fixed. That takes valuable time away from more strategic initiatives.

Steps to take:

Consider an AP automation solution that uses optical character recognition (OCR) technology to read and enter invoice data. Paper invoices can be added to the system as easily as snapping a photo on your phone, and electronic invoices can be emailed to an automated inbox.

The software reads each invoice automatically and enters it for your review. By cutting out manual processes, you minimize the chance of human errors.

3. Establish KPIs to measure accounts payable efficiency

Sometimes changes don't have the desired effect. Every AP process and team has its own nuances and what works for one team might not work for you.

Remember, accounts payable process improvement is not about getting to the perfect system, but your perfect system.

But determining whether a change was successful or not shouldn't depend on gut checks. This is where KPIs come in.

Steps to take:

Measure the success of your process improvement efforts by tracking 11 accounts payable metrics. Here’s a sample of these key performance indicators (KPIs):

  • Cost, on average, of processing a single invoice
  • Average payment processing time
  • Percent of exceptions in total invoices processed
  • Percent of early payment discounts captured
  • Number of questions or disputes from vendors

Give your changes time to come into effect before deciding if they were a success or not.

Check in on your KPIs regularly to see how they're trending. The change might not have helped you hit your KPI, but if the metric is consistently trending towards your goal, there's good reason to believe you'll hit that mark down the line.

4. Establish fraud detection and prevention measures

According to FBI Statistics, Business Email Compromise continues to grow with a 65% increase in global exposed losses between July 2019 and December 2021, for a total of over USD 43 billion between June 2016 and December 2021.

Plus, if you’re like 61 percent of the respondents in a recent Association for Financial Professionals survey, catching fraud is a top priority.

In many of these cases, bad actors managed to interrupt the AP process, rerouting payments to the wrong place.

Steps to take:

Accounts payable automation software uses artificial intelligence (AI) and machine learning (ML) to identify unusual patterns that can indicate fraud attempts, such as:

  • ACH Fraud
  • Asset Misappropriation
  • Duplicate Invoices
  • Change of Master Data

An automated AP platform can include several techniques to identify and prevent fraud:

  • Anomaly Detection: The system can identify unusual patterns. For example, if a supplier submits an invoice that is significantly larger than their average invoice, the system flags the invoice for review.
  • Process Reliability: The automated process follows a predefined and set procedure that can not be easily circumvented. It also provides an automatic, time-stamped audit trail.
  • Purchase Order (PO) Matching: The system performs an early-warning check as each invoice arrives, making sure the invoice matches any underlying purchase order.

5. Prevent duplicate invoice payments 

It’s far too easy to pay the same invoice more than once. Paper-based systems are especially prone to these accidents, but even electronic spreadsheets won’t catch every duplicate payment error.

Duplicate payments happen for a variety of reasons. Payments might not be recorded correctly at the time they’re made, for example, or a duplicate vendor record could confuse your payment trail, leaving you with one record where the payment was recorded and another where it wasn’t.

Steps to take:

Take advantage of the following changes to minimize duplicate payments:

  • Clean master vendor files: Archive vendors you no longer use, eliminate duplicate vendor records, and make sure you have the most up-to-date vendor information.
  • Require a valid PO number: Eliminate informal procurement processes as much as you can. Every pre-defined purchase should start with a purchase order, and each invoice should be matched with its originating order.
  • Only pay from one source document: If your company sends out a purchase order and receives an invoice upon delivery, make it a policy only to pay from the invoice. This can help avoid paying for the same goods or services twice.
  • Mark invoices as paid immediately: This last step is crucial. Mark all invoices paid as soon as you send the payment to minimize the risk of a duplicate payment. A bill pay platform can handle this for you, making this step automatic.

6. Track and resolve disputes promptly to avoid slow invoice processing

In most businesses, invoice processing is still highly manual. Even if you use electronic spreadsheets, someone has to read each invoice and enter the payee, invoice number, amount, and other information by hand. That’s a time-consuming, manual process.

Then, someone has to take the time to send out emails or circulate paper invoices to gather approvals. That creates another bottleneck as those requests sit in an inbox or on a desk, waiting for attention.

From data entry to approvals to final payment processing, each step in your payable workflow can stall the vendor payment process, resulting in missed due dates and late fees.

Steps to take:

It's hard to resolve a dispute when you can't track where a payment is in the AP process or what steps other team members might already have taken. And the longer disputes take to resolve, the more they can damage your vendor relationships.

With AP automation software:

  • Vendors can receive automatic updates when invoices are received when payment is approved, and when payment is sent
  • AP team members can easily track invoices to identify where they are in the system and why the approval process has been held up
  • Communication about each invoice is tracked and stored with that specific invoice, so following the conversation is as easy as looking up the invoice in the system
  • Approval requests and reminders can be sent automatically, and invoices can even be approved on a mobile device, minimizing the chance of delays

7. Streamline your invoice approval workflow with defined roles

When an accounts payable process has multiple people involved, each person must know exactly what their responsibilities are.

Oftentimes, there are people involved who aren't part of the finance team. For example, the head of marketing might need to approve invoices for filming an ad.

Everyone should be on the same page when it comes to who's responsible for what and be notified when the invoice is ready for their contribution.

Otherwise, you risk the bystander effect showing up in the workplace where everyone thinks someone else is taking on the task.

Steps to take:

Some AP automation solutions allow your accounts payable department to set custom rules and workflows including which invoices do and don’t need approval and where approval requests should be routed.

The system will send follow-up reminders and monitor due dates, flagging any invoice that’s being held up too long in your workflow.

Approvals become less stressful for everyone when there’s an automated procedure in place to keep things on track.

8. Use a single point of entry for invoices to avoid missing invoices

In paper-based invoice management systems, invoices may end up buried on a desk under other paperwork. In electronic systems, invoices can be lost in email chains or end up in a spam folder.

Either way, those missing invoices can result in lost early payment discounts, late payments, and poor supplier relationships.

Steps to take:

Set up your system to route all invoices into the same workflow, so they all follow the same process.

As challenging as that sounds, an AP automation solution can help by providing many easy ways to enter an invoice into that workflow.

  • Vendors can email invoices directly to an automated inbox
  • AP team members can scan invoices into the same inbox, or even snap photos on their phones using a mobile app
  • Managers throughout different departments can do the same thing, sending those invoices automatically to the same starting point

Using one point of entry ensures that the same systems, security checks, and approval rules are applied to every invoice no matter how it might arrive.

9. Set up payment reminders to reduce late or forgotten payments

If all your invoices are recurring and consistent, making payments can feel like muscle memory. The problem is if an invoice breaks that pattern, it's likely to be missed.

Steps to take:

Set up automated payment reminders so once an invoice is entered, a reminder is created some time before the due date. This is easier when you receive digital invoices which often already come with reminders.

Continuing to iterate your accounts payable process

Accounts payable process improvement isn’t a final destination. It’s an ongoing system of analyzing data, finding issues, and implementing change. While the most important improvements for your team will depend on your own AP process, the following checklist helps you keep up with how accounts payable processes are trending.

  • Less established in global, enterprise-scale expense programs with multi-country regulatory requirements

BILL Spend & Expense pairs corporate cards with AI-powered expense management and budget controls in a single platform at no cost—teams aren't paying per user or upgrading to unlock features that competitors gate behind paid tiers.

Merchant-level spend controls and auto-freeze on incomplete transactions give admins granular oversight without manual policing, and two-way ERP integrations are included free where Ramp and Brex charge for NetSuite and Sage Intacct access. The main trade-off is an initial 12-month rewards holding period before accumulated points can be redeemed. [1][2][3][4]

Commonly compared to: Ramp and Brex (for card-first expense management), and SAP Concur (for enterprise expense programs).

Pricing

  • AI-powered receipt capture via ExpenseIt on the SAP Concur mobile app, with smart matching that combines credit card charges and e-receipts into expense reports automatically [7]
  • Configurable approval workflows with built-in audit rules that flag policy exceptions, plus optional Intelligent Audit and Verify add-ons for automated compliance checks [6][7]
  • Modular product suite: Concur Expense, Concur Travel, and Concur Invoice are separate products that can be purchased individually or together, so organizations can start with expense management and add capabilities over time [6]
  • Bank card feed integrations that import corporate card transactions directly into expense reports for automatic reconciliation [6]
  • Joule, SAP's AI assistant, for expense report review, spend analysis, and cost estimation [6]
  • Budget tracking and monitoring tools that give finance teams visibility into spend against departmental or project-level budgets [6]
  • Support for global operations with multi-currency expense reporting and country-specific tax and regulatory compliance tools [6]
  • Pro: 300+ pre-built integrations including native SAP ERP sync [7][8]
  • Pro: Global coverage with multi-currency and regulatory compliance tools [6]
  • Pro: Modular—add travel or invoice management without switching platforms [6]
  • Pro: AI-powered receipt capture and smart matching via ExpenseIt [7]
  • Con: Quote-based pricing; no published rates on the website [6]
  • Con: No corporate card offering; relies on bank card feed integrations [6]
  • Con: Implementation can be complex for smaller organizations [6]
  • Con: Live support requires purchasing the User Support Desk service [6]

SAP Concur is the incumbent in expense management software, with the largest partner ecosystem and broadest global footprint on this list. Its modular approach gives large organizations flexibility to start with expense management and layer on travel or invoice capabilities independently.

The trade-off is complexity—pricing is opaque, there's no corporate card offering, and smaller teams may find the platform more than they need. Organizations already in the SAP ecosystem will get the most value from native S/4HANA integration. [6][7][8]

Commonly compared to: BILL (for SMB expense management), and Coupa (for enterprise spend management).

Best for a broad spend platform
4.8 on G2
  • Corporate cards with customizable spend controls by merchant, category, employee, or department, plus unlimited virtual and physical cards [9][10]
  • AI-powered receipt matching, transaction coding, and memo suggestions that auto-populate as soon as a card is swiped [9]
  • Policy agent that reviews every expense against company policy, auto-approves compliant transactions, and escalates only exceptions with full audit trail [9]
  • Expense submission via SMS, Slack, or Microsoft Teams in addition to web and mobile app [9]
  • Reimbursements for out-of-pocket expenses paid to employees' bank accounts in 1–2 business days [9]
  • Real-time spend reporting with custom dashboards, natural-language queries, and proactive overspend alerts [9]
  • Broader spend platform that includes AP automation, procurement, vendor management, and treasury alongside expense management [9]

Pros

  • Free plan includes corporate cards, expenses, and bill pay [11]
  • AI policy agent reviews 100% of expenses automatically [9]
  • Submit expenses via SMS, Slack, or Teams—no app required [9]
  • Broader spend platform covers AP, procurement, and vendor management [9]

Cons

  • Budget tracking requires Ramp Plus at $15/user/month [11]
  • NetSuite, Sage Intacct, and Dynamics integrations require a paid plan [11]
  • HRIS syncs and auto-lock cards require a paid plan [11]
  • Credit limits fluctuate daily based on connected bank balance [12]

Ramp's strength is breadth—it's not just an expense tool but a full spend management platform that includes AP automation, procurement, and vendor management alongside expenses. The AI policy agent is a differentiator, reviewing every transaction against company rules rather than relying on manual manager approvals.

The trade-off is that several features mid-market teams rely on—budget tracking, ERP integrations beyond QuickBooks and Xero, and HRIS syncs—require upgrading to Ramp Plus at $15/user/month plus a platform fee. [9][11]

Commonly compared to: Brex and BILL (for corporate cards and expense management), and SAP Concur (for enterprise expense programs).

Brex
Best for global teams
4.8 on G2
  • Corporate cards with customizable spend limits by role, department, or category, plus auto-approve for in-policy expenses and auto-decline for out-of-policy spend [13][14]
  • AI-powered expense reviews that auto-approve compliant transactions and surface only exceptions for human review, with clear visibility into why a transaction is flagged [13]
  • Auto-generated receipts and memos with OCR that matches receipts in any language or currency, plus automatic GL coding by department, project, and entity [13]
  • Live Budgets that let department heads set top-level budgets, provision spend to individuals or teams, and track usage in real time with anomaly detection [13]
  • Global reimbursements in 70+ countries in employees' local currency, with subsidiaries able to issue reimbursements from local bank accounts [13]
  • Expense submission and approval via Slack and WhatsApp, with in-app commenting on individual transactions [13]
  • Broader financial platform that includes bill pay, business banking with up to 3.68% yield, and treasury alongside expense management [14]

Pros

  • Free plan includes corporate cards, expenses, bill pay, and travel [15]
  • AI expense reviews with 99% average policy compliance rate [14]
  • Global reimbursements in 70+ countries in local currency [13]
  • Live Budgets with real-time tracking and anomaly detection [13]

Cons

  • Live Budgets require Premium at $12/user/month [15]
  • HRIS syncs and customizable ERP integrations require a paid plan [15]
  • Credit limits fluctuate daily based on connected bank balance [16]
  • Multiple expense policies and dynamic review chains require Premium [15]

Brex positions itself as a full financial stack for startups—cards, expenses, banking, and treasury in one platform. The AI expense reviews and 99% average compliance rate (per Brex's internal metrics) are notable, and the global reimbursement coverage across 70+ countries is broader than most competitors on this list.

Like Ramp, Brex gates budget management and HRIS integrations behind a paid tier, and credit limits fluctuate daily based on your bank balance. Teams that need predictable spending power or are past the startup stage may find the pricing structure adds up. [13][14][15]

Expensify
Best for simple reimbursements
4.5 on G2
  • SmartScan receipt capture by photo, email forwarding (receipts@expensify.com), or text message; auto-extracts transaction details and categorizes expenses [17]
  • Bring-your-own-card support: link existing corporate cards from 10,000+ banks globally for automatic reconciliation without switching card providers [17]
  • Expensify Visa Commercial Card with cash back on US purchases; cash back first offsets the Expensify subscription cost, then flows to the company's bank account [17]
  • Concierge AI for automated expense categorization, policy violation flagging, rule enforcement, and error reduction [17]
  • Global reimbursements for employees and independent contractors in their local currency [17]
  • Chat-based collaboration directly on individual expenses to resolve questions in real time rather than through email follow-ups [17]
  • 45+ integrations including QuickBooks, NetSuite, Sage Intacct, Xero, Workday, and Gusto [17]

Pros

  • Bring-your-own-card from 10,000+ banks globally [17]
  • Expensify Card cash back can offset the subscription cost [17]
  • SmartScan receipt capture by photo, email, or text message [17]
  • 45+ integrations including major ERPs and payroll systems [17]

Cons

  • No free plan; starts at $5/user/month [18]
  • Pricing structure varies by card spend volume [18]
  • Budget management, advanced approvals, and expense policies require Collect or Control plans [17]
  • No department-level budget management on par with card-first platforms

Expensify's strength is accessibility—it has the lowest barrier to entry for teams that just need to start tracking expenses and submitting receipts. The bring-your-own-card support from 10,000+ banks means companies don't have to switch card providers, and the SmartScan receipt capture (by photo, email, or text) is one of the more flexible input methods on this list.

The trade-off is that several features mid-market teams expect—budget management, advanced approvals, and expense policies—require upgrading to the Collect or Control plans, and spend controls are primarily limited to the Expensify Card rather than extending across all connected cards. [17][18]

Commonly compared to: Zoho Expense (for budget-friendly expense management), and BILL and Ramp (for integrated cards and expenses).

Zoho Expense
Best for budget-conscious teams
4.5 on G2
  • Autoscan receipt capture with OCR that auto-categorizes and itemizes each expense, plus the ability to split or tag expenses across departments, projects, or cost centers [19][20]
  • Automated per diem calculations with pre-defined rules based on country, location, and trip details for regional compliance [20]
  • Corporate card management with real-time feeds that automatically match transactions to uploaded receipts for faster reconciliation [20]
  • Mileage tracking with four input methods across Android, iPhone, and Apple Watch [20]
  • Configurable approval workflows, expense policies, and audit rules with detailed audit trails for compliance [19][20]
  • Custom modules, workflow automation, webhooks, and configurable UI elements for businesses that need tailored expense processes [19]
  • Active-user pricing model: only employees who actually create expenses are charged, so admins and approvers who don't submit reports are free [21]

Pros

  • Free plan available for up to 3 users with core expense tracking [21]
  • Active-user pricing—admins and approvers aren't charged [21]
  • Automated per diem calculations by country and location [20]
  • Deep customization with custom modules and workflow automation [19]

Cons

  • Corporate card feeds and multi-level approvals require Standard plan [21]
  • Deepest value requires the broader Zoho ecosystem (Books, People, CRM) [19]
  • No corporate card offering; relies on connecting existing cards [20]
  • Travel booking, per diem, and live budgets require Premium plan [21]

Zoho Expense offers unusually deep customization at a low price point—custom modules, workflow automation, webhooks, and configurable UI elements that most competitors don't expose. The active-user pricing model is genuinely cost-effective for companies where only a portion of employees submit expenses regularly.

The trade-off is that there's no corporate card offering—you'll need to connect your existing cards—and the platform delivers its deepest value when used alongside other Zoho products like Zoho Books and Zoho People. [19][20][21]
