Welcome back to our Best Practices for AP Approval Workflow blog series! In the previous article, we discussed how to ask the right questions that help you identify clients’ common bill pay challenges and the impact it may have on their business. To further help you jump-start discussions, we also provided an Approval Workflow Checklist to help you document their current process.

Now we’ll move on to Key Performance Indicators (KPIs). More specifically, how to use aggregate client data to identify the right set of KPIs—the time and cost resources allocated to their approval process. Indicators of areas in need of refinement to develop efficiencies, avoid late fees, and reduce AP pain points altogether.

Your clients can’t begin to understand where they are today with process efficiencies, time, and cost if you aren’t tracking these indicators. When you identify key performance indicators, it provides a repeatable, structured process within which you consistently and accurately measure goals against outcomes—building a foundation for workflow changes.

KPI 1: Average time spent on manual data entry

Depending on the business, the bill pay process can range from simple to highly complex, encompassing multiple systems for data entry. This leads to manual input (hello higher risk of error) and duplication of work.

For the sake of efficiency and reducing human-driven errors, it’s imperative to reduce manual tasks like data entry, routing, or signing paper checks. To accomplish this, you must first calculate the average time associated with manual tasks. Measuring time will help clients see just how much time and effort is wasted on paper-driven, non-automated work. And in comparison, the hours (even days) they can save when AP workflow is automated.

Advanced systems like BILL’s, which come equipped with AI functionality, can automate the bill pay process from start to finish—greatly reducing time spent on manual processes.

A solution with AI can even help prevent duplicate payments, typos, and other errors that create exceptions.

KPI 2: Average time to approve a bill

Bill approval should be fast, efficient, and accurate; however, if clients are adhering to manual processes, this isn’t always the case for them.

The goal here is to simplify the process and remove obstacles so stakeholders can approve bills in a timely, highly efficient, and digital manner. This helps business owners get out of the back office so they can focus their attention on profit-building efforts to grow and thrive. After all, they likely didn’t start their enterprise because they’re passionate about paying bills.

Bill pay technology today offers the ability to sign off on bills anytime, anywhere, and from a mobile device—timestamped and attached to an audit trail.

For all these reasons, this KPI should be high on the list. Be sure to get a current measurement on the average time from bill creation to payment approval for an accurate comparison to results collected, post-automated workflow implementation.

KPI 3: Average time to pay a bill

Applying the above KPIs makes easier work of calculating this indicator. The goal is to measure the amount of time it takes from receipt of an invoice to payment submitted to a vendor.

Progressively reducing the time allotted to pay bills can make a big impact on bill pay costs (think fewer staff hours or reallocating those resources elsewhere), reduce late payment fees, and free the client’s time to redirect effort to other areas of business. It’s a huge win all around when automation is at the center of the AP workflow.

KPI 4: Total fees paid

Late fees translate to money down the toilet. Regularly measuring total late fees (and other associated fees) paid is crucial if clients are to reel in payment costs and additional money going out to vendors—as well as maintain positive vendor relationships.

By improving this KPI, your clients can save large sums of cash over time and preserve vendor relationships and their reputation.

KPI 5: Total cost of materials

The materials that make up a manual bill pay process can come with a hefty price tag. Check stock, postage, envelopes, and file management are all part of the equation and can quickly add up. Consider also that the higher the transaction amount the bigger the price.

Stay focused on this KPI to help clients understand these “concealed” costs and how to reduce them.

An advanced bill pay solution allows you to cut most, if not all, physical materials costs.

KPI 6: Average cost to pay a bill

Data speaks volumes. According to this Goldman Sachs Equity Research report, the average business using paper checks is paying up to $22 per transaction. Yikes!

This cost is the sum of all the previous KPIs mentioned—complete with related fees, the time it takes to do it, materials costs, and more.

This figure often stays “out of sight, out of mind” and may be hurting the client’s bottom line more than they realize.

The hard fact is that B2B payments are an exceedingly inefficient market with a lot of room for improvement. Staying on top of this KPI can help clients save a great deal of money over time as they improve their bill pay workflow.

The opportunity to help clients save money on B2B payments is massive!

Stay tuned for even more…

Starting a conversation with clients is the first step to transitioning them to an automated bill pay workflow. Identifying and tracking top KPIs is the next big step.

Once clients have a firm grasp on how they can improve efficiency, cut costs, and save time, they’ll be far more motivated to jump the manually navigated ship and move on to smoother automated waters. Start with the KPIs laid out for you here as you continue to move clients forward to bill pay bliss.

Be sure to come back for the final installment of this three-part series where we’ll conclude with a clear roadmap for implementing an end-to-end automated bill pay workflow.

  • AI-powered auto-categorization and receipt matching that connects card transactions and expenses into a single reconciliation workflow [1]
  • Customizable budgets with spend controls based on merchant, amount, receipt requirements, and configurable approval workflows [3]
  • Auto-freeze on cards with incomplete transactions, ensuring receipts and documentation are captured before additional spend is approved [1]
  • Up to 7x points on restaurants, 5x on hotels, 2x on recurring software, and 1.5x on all other purchases (rates shown are for weekly or daily billing cycle; rates vary by billing frequency) [2]
  • Two-way sync with QuickBooks, NetSuite, Sage Intacct, Xero, and Microsoft Dynamics; additional integrations with Acumatica, Slack, and HRIS platforms [1]
  • Pro: $0/user/month with all features included—no paid tier to unlock [4]
  • Pro: Merchant controls and auto-freeze cards at no extra cost [1]
  • Pro: Credit lines that don't fluctuate daily based on bank balance [4]
  • Pro: All ERP integrations (NetSuite, Sage Intacct, Xero) included free [1]
  • 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]

  • 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]

  • 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]
  • 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]
  • Ideal if you need: A financial platform built for startups that includes expense management as part of a broader stack with banking, treasury, and AP. [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]

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]
  • 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]
