A recent Harvard Business Review article suggests that the best use of AI is to support human intelligence, not replace it, using smart processes that play to the strengths of both human and machine.

That vision is already playing out in the world of digital payments and payment providers. By carefully structuring the accounts payable (AP) process, humans are partnering with AI-enabled payment systems to improve speed, accuracy, compliance, and fraud protection in financial operations. 

What is AI in the payments industry?

AI in the payments industry combines artificial intelligence (AI) with AP best practices to standardize and automate payment systems. The AI makes sure the right procedures are followed while streamlining operations for its human partners. As a result, bookkeeping and accounting processes become more efficient and more accurate.

The role of AI in digital payments

What is the role of artificial intelligence in digital payments?

By doing things like automatically applying approval rules or detecting common patterns found in payments fraud, AI partners with human beings to improve digital payments processes from start to finish.

AI for invoice processing

One form of AI uses computing power to recognize text in images. Known as optical character recognition, or OCR, it's used in invoice processing to read invoices and other financial documents, entering the relevant information into financial systems for human review. By adding machine learning, the computer can get better at recognizing this same information in future invoices:

  • Transaction data, such as price
  • Customer data, like shipping and billing addresses
  • Potential cost savings in payment terms
  • And more

This human-AI process partnership improves accuracy and minimizes the need for manual data entry, saving teams hours of valuable time.

Because AI can scan human text, it can also detect duplicate invoice numbers and recognize the presence of multiple bills within multi-page invoices. This reduces the chance of human error and helps protect against fraudulent transactions.

AI for approval rules

By recognizing data in invoices, computers can automatically apply the right approval rules to each invoice, sending them to approvers without the need for human intervention. This streamlines the approval process and captures approvals electronically, even on mobile devices.

AI for automatic audit trails

Not every application of financial automation uses true AI. An automatic audit log, for example, keeps a time-stamped audit trail of everything that happens throughout the payments process. This is a relatively straightforward algorithm that can save a tremendous amount of time during an audit.

AI for payment processing

Another automation that doesn't rely on artificial intelligence is the ability to remember personalized payment options and preferences. Today's payment solutions improve the customer experience (or vendor experience) by letting them choose their preferred payment methods from multiple payment options—such as ACH, credit card, check, or international wire—as part of the payment process.

AI for fraud detection and prevention

Natural language processing (NLP) is a form of AI that goes beyond recognizing characters, letting computers read and process human text.

With invoice, approval, and payment logs compiled in one place, AI can scan through every touchpoint in the AP process, summarize hundreds of pages of data for human auditors, and flag potentially fraudulent transactions as well as areas for special attention.

The technology behind AI in payments

AI technology used by payment providers is not unlike the tech behind thousands of other AI applications. What's unique is how the human-AI process partnership is structured.

When it comes to AP automation, human intelligence is placed at the forefront:

  • AI reads invoices and enters data. Humans review that data before accepting it into the system. 
  • Computer algorithms apply approval rules to route each invoice to the right people. Human beings are the actual approvers.
  • AI flags duplicate invoice numbers or invoice amounts that don't match purchase orders for human scrutiny. Human beings then review to decide whether there's a problem and what to do about it.

In each case, AI never overrides or replaces human judgment. It simply streamlines manual tasks and applies best practices automatically.

How does AI affect the digital payments industry today? 

The processes outlined above aren't science fiction. They're very real systems being used today by over 5 million BILL network members to automate the way they pay and get paid.

AI use cases in AP and payment processes

Here are just a few examples of how companies are using AI-powered software in their financial operations:

  • For Boys and Girls Clubs of Silicon Valley, AP automation frees up hours of team time to focus on program expansion.
  • Bombas uses it for both domestic and international vendor payments, using the improved cash flow visibility for proactive spend projections.
  • Bear Robotics knows AI well. Through AI and autonomous robot technology, the company deploys robots to take care of drink serving, food running, and table bussing, freeing the wait staff to focus on delivering outstanding service. They also use it to free their finance team from hours of manual paperwork, implementing a seamless, scalable AP process to support international growth.

AI technologies automate financial operations while providing advanced analysis for their human partners.

Time savings

AI-powered software is a game-changer for financial professionals, saving them countless hours on routine accounting tasks. This gives them more time to focus on other important aspects of their business that contribute to growth.

Improved accuracy

By using AI-powered software to delegate routine tasks, finance teams save time and achieve more accurate results compared to manual data entry. With the help of NLP software, errors associated with data entry can be minimized, giving teams greater confidence in their expense reports and other data.

Better business decisions

One of the most significant recent financial trends is how often financial professionals are being asked to weigh in on key business decisions. AI gives finance teams access to real-time AP and cash flow data as well as predictive analytics to explore future trends through cash flow forecasting.

Challenges of AI in payments

Challenges of AI in payments

As impressive as AI is, it still faces a few key challenges:

  • AI can't adjust to unforeseen developments
  • AI often misses contextual meaning
  • AI may have trouble with technical jargon
  • AI may struggle to tell the difference between innocent error and fraudulent intent

Fortunately, people do these things extremely well, and AI excels at things that tend to slow us down. That’s why humans and machines work so much more efficiently together than we ever could on our own.

The future of AI in payments

There's no question that AI is changing the face of financial operations, but the day when machines could replace human finance teams won't be any time soon—if ever. Instead, AI is partnering with human beings to help improve accuracy in their transaction data, prevent fraud, and ensure the application of best practices throughout the AP process.

AI may be developing at a dizzying speed, but the need for strong finance teams is greater than ever—teams that depend on AI to augment their core strengths and help them make confident decisions in real time.

  • Con: 12-month holding period before rewards can be redeemed [2]
  • Con: Category reward multipliers cap at $5,000/month per category [2]
  • Con: 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).

  • 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: Mid-market and enterprise organizations that need a globally scalable expense management platform with configurable compliance tools and a large partner ecosystem. [6][7][8]
  • Highlights: AI-powered receipt capture via ExpenseIt, configurable approval workflows with built-in audit rules, optional Intelligent Audit and Verify add-ons for automated compliance checks, 300+ app integrations, and native SAP ERP sync. [6][7][8]
  • Ideal if you need: An expense platform that integrates natively with SAP S/4HANA or other enterprise ERPs, with the flexibility to add modules like Concur Travel or Concur Invoice over time. [6][7]

  • 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]
  • Pro: Free plan includes corporate cards, expenses, and bill pay [11]
  • Pro: AI policy agent reviews 100% of expenses automatically [9]
  • Pro: Submit expenses via SMS, Slack, or Teams—no app required [9]
  • Pro: Broader spend platform covers AP, procurement, and vendor management [9]
  • Con: Budget tracking requires Ramp Plus at $15/user/month [11]
  • Con: NetSuite, Sage Intacct, and Dynamics integrations require a paid plan [11]
  • Con: HRIS syncs and auto-lock cards require a paid plan [11]
  • Con: 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).

  • Best for: Fast-growing companies that want corporate cards, expense management, and accounts payable on a single platform with AI-powered automation. [9][10]
  • Highlights: Corporate cards with built-in spend controls, AI-powered receipt matching and expense coding, a policy agent that reviews 100% of expenses and flags only exceptions, and submission via SMS, Slack, or Microsoft Teams. [9][10]
  • Ideal if you need: A card-first platform where expense management is one part of a larger system that also covers AP, procurement, and vendor management. [9]

  • 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]
  • Pro: Free plan includes corporate cards, expenses, bill pay, and travel [15]
  • Pro: AI expense reviews with 99% average policy compliance rate [14]
  • Pro: Global reimbursements in 70+ countries in local currency [13]
  • Pro: Live Budgets with real-time tracking and anomaly detection [13]
  • Con: Live Budgets require Premium at $12/user/month [15]
  • Con: HRIS syncs and customizable ERP integrations require a paid plan [15]
  • Con: Credit limits fluctuate daily based on connected bank balance [16]
  • Con: 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]

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

  • Best for: Startups and high-growth companies that want a global financial platform covering corporate cards, expense management, bill pay, and business banking. [13][14]
  • Highlights: AI-powered expense reviews that auto-approve compliant transactions, corporate cards with built-in policy controls, Live Budgets for real-time tracking, global reimbursements in 70+ countries, and OCR receipt matching in any language or currency. [13][14]

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]
  • Pro: Bring-your-own-card from 10,000+ banks globally [17]
  • Pro: Expensify Card cash back can offset the subscription cost [17]
  • Pro: SmartScan receipt capture by photo, email, or text message [17]
  • Pro: 45+ integrations including major ERPs and payroll systems [17]
  • Con: No free plan; starts at $5/user/month [18]
  • Con: Pricing structure varies by card spend volume [18]
  • Con: Budget management, advanced approvals, and expense policies require Collect or Control plans [17]
  • Con: 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).

  • Best for: Small and midsize businesses that want a mobile-first expense management tool with flexible card options, including the ability to link existing corporate cards from 10,000+ banks. [17]
  • Highlights: SmartScan receipt capture by photo, email, or text message; bring-your-own-card support from 10,000+ banks globally; Expensify Visa Commercial Card with cash back that offsets subscription costs; and Concierge AI for automated categorization and policy enforcement. [17]
  • Ideal if you need: A lower-cost entry point for expense management where employees can start submitting receipts immediately without switching corporate card providers. [17]

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]
  • Pro: Free plan available for up to 3 users with core expense tracking [21]
  • Pro: Active-user pricing—admins and approvers aren't charged [21]
  • Pro: Automated per diem calculations by country and location [20]
  • Pro: Deep customization with custom modules and workflow automation [19]
  • Con: Corporate card feeds and multi-level approvals require Standard plan [21]
  • Con: Deepest value requires the broader Zoho ecosystem (Books, People, CRM) [19]
  • Con: No corporate card offering; relies on connecting existing cards [20]
  • Con: 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]

Commonly compared to: Expensify (for budget-friendly expense management), and SAP Concur (for global compliance and customization).

  • Best for: Small and midsize businesses that want an affordable, highly customizable expense management platform with strong global compliance features and active-user pricing. [19][20][21]
  • Highlights: Autoscan receipt capture with OCR, automated per diem calculations by country and location, corporate card reconciliation with real-time feeds, mileage tracking across multiple input methods, and active-user pricing starting at $4/user/month. [19][20][21]
  • Ideal if you need: A low-cost expense management tool with deep customization options and native integration with the broader Zoho ecosystem (Zoho Books, Zoho People, Zoho CRM). [19][20]
