Bill.com is a cloud software company that automates how small businesses pay their bills and get paid, processing over $290 billion in annual payment volume. The company serves approximately 488,600 businesses, earning revenue through a mix of subscription fees, transaction fees on payments, and interest on the money it holds for customers. While growth has moderated from its pandemic-era peaks, the business reached annual profitability in 2024 and continues to scale its payment network of 7.1 million members.
The investment thesis on Bill.com is that its digital payment network creates a "lock-in" effect where businesses join because their suppliers are already there, turning a simple software tool into a structural data asset. Most small businesses still rely on paper checks, but as they move to Bill.com, the platform captures the full transaction data that allows it to offer higher-margin financial products like corporate cards and credit. If Bill.com remains the primary "operating system" for small business cash flow while expanding its take rate, the business becomes a high-margin cash machine.
We lean positive on Bill.com because it has successfully transitioned from a high-burn growth story into a profitable platform with a dominant position in the small business back office. The core business is proving it can grow in the double digits while generating significant free cash flow, even as the broader economy remains cautious. What would worry us is a failure to move customers toward higher-margin payment types, which would cap the company's long-term earnings power.
Bill.com's stock soared when it first launched but has since crashed to about 80% below its high point from five years ago. The business grew fast during the pandemic, but that excitement faded and growth cooled off. Now the company is changing its leadership and chasing new technology to fix its performance.
What does it do?
Bill.com is a growth-stage business that earns money by automating the back-office financial tasks for small businesses, specifically how they pay bills and collect money from customers. When a business uses Bill.com, it stops writing paper checks and instead uses the platform to digitize invoices, route them for approval, and send electronic payments. Bill.com makes money through monthly subscription fees per user, transaction fees (such as a cut of virtual card payments or international wire fees), and by earning interest on the money that is moving through its system. By connecting both the payer and the receiver on one network, it makes the payment process faster and more transparent than traditional bank transfers.
Where does revenue come from?
The vast majority of revenue comes from software subscriptions and transaction fees, though interest income is currently a significant contributor. Subscription fees provide a steady base, while transaction fees grow as businesses process more volume or use specialized payment types like cross-border transfers. A smaller but high-margin portion of revenue, roughly 12% in the latest quarter, comes from "float" or the interest earned on customer funds held during the payment process.
Revenue Breakdown
Who are its customers?
Bill.com serves 488,600 active businesses, ranging from solo entrepreneurs to mid-sized companies with hundreds of employees. As of the most recent report, the company's core platform serves 164,800 direct accounts payable and accounts receivable customers, while its "Spend & Expense" unit (formerly Divvy) serves 39,500 spending businesses. The platform also includes a massive secondary group of 7.1 million network members, which includes the suppliers and vendors who have signed up to receive payments from Bill.com's primary customers. This total payment volume (TPV) reached $79.0 billion in the most recent quarter, representing an 11% increase over the prior year.
What gives it staying power?
Bill.com has staying power because once a business connects its accounting software and invites all its suppliers to the platform, the cost and effort of leaving are very high. This "switching cost" is reinforced by the 7.1 million suppliers already in the network; a new competitor would struggle to replicate that pre-populated directory of payment identities.
Where is it headed?
Bill.com is betting heavily on becoming a "one-stop shop" for all business spending by integrating its bill-pay software with its corporate card and expense management tools. Management is moving away from being just a payment utility and toward a comprehensive platform that manages everything from office supply purchases to global vendor payments. If successful, this increases the "take rate" or the amount of profit Bill.com makes on every dollar that flows through its system.
Revenue growth is moderating but remains healthy as the business matures. Annual revenue reached $1.46 billion in 2025, a steady climb from $1.06 billion two years prior, though the triple-digit growth of the past has settled into a 10-15% range. This shift reflects a move from aggressive customer acquisition to deeper monetization of the existing 488,600 businesses on the platform.
Cash generation is the real strength of the financial story right now. Free cash flow reached $310 million in 2025, which is significantly higher than GAAP net income, showing that the software-as-a-service model is finally producing "real" cash as it scales. Because the business requires very little physical equipment (CapEx), almost every dollar of operating cash can be reinvested or used to buy back shares.
The balance sheet is exceptionally strong with a massive net cash position. The company holds $3.2 billion in cash and short-term investments against roughly $1.6 billion in debt, providing a massive cushion for acquisitions or further stock repurchases. For a software business of this scale, this level of liquidity is a major strategic advantage that allows it to outlast smaller, less-funded competitors.
Bill.com has successfully transitioned into a self-funding cash machine that no longer depends on outside capital. The combination of high gross margins and rising free cash flow defines a business that has turned the corner on profitability while maintaining a dominant market share in the SMB payment space. Bill.com is a financially resilient business with high cash quality.
The Spend & Expense segment, which includes the corporate card business, is growing at 21%, significantly faster than the core software business. This is a critical win because card volume carries higher margins and proves that Bill.com can successfully sell more products to its existing customer base.
Interest income on customer funds fell 9% this quarter as interest rates began to stabilize or decline. While this is a small part of the total mix, it is almost pure profit; if this trend continues, the core payment and software business will have to work harder to maintain the same level of overall margin.
The SMB payments market is roughly $25 trillion in total volume today, growing at a mid-teens rate as businesses move away from paper checks and manual entry. This market is on track to exceed $40 trillion by 2030 as digital transformation penetrates smaller, less tech-savvy firms. While the industry is growing fast, competition is intense, making it a battle for distribution rather than a race on price alone. Bill.com stands as the independent leader in this space, positioned as a neutral platform that works with any bank or accounting software.
The competitive dynamic is currently a battle between "best-of-breed" specialists like Bill.com and "good enough" bundles from accounting software giants and big banks. Barriers to entry for simple software are low, but the barriers to building a reliable, secure payment network that handles billions in volume are high. This structure favors established players with deep integrations.
Newer fintechs like Melio and Ramp are attacking specific parts of the Bill.com platform, often with simpler pricing or higher card rewards to lure customers away. The most dangerous threat is Intuit's QuickBooks, which can embed bill-pay directly into the accounting software that most Bill.com customers already use. While Bill.com is more powerful, the convenience of a built-in tool is a constant pressure on its customer acquisition costs.
Bill.com is currently holding its ground by moving up-market and integrating its corporate card more deeply. It remains the "gold standard" for mid-sized firms that have outgrown basic accounting tools.
The primary source of protection is high switching costs: once a business integrates Bill.com with its accounting software and sets up thousands of vendors, the "pain of exit" is substantial. The 7.1 million network members create a partial network effect, as suppliers prefer to receive payments through a system they already use for other clients. This is evidenced by the massive $292 billion in total volume processed last year.
The company's 81% gross margins prove that it has real pricing power, as customers are willing to pay a premium for the time saved and the reduction in fraud risk. However, the lack of a true, two-sided network effect (where the platform is useless without the other side) keeps this moat in the "narrow" category. It is a very sticky business, but not an impenetrable one.
The moat is currently stable, as the company's "Spend & Expense" integration is creating even deeper ties with its customers. The single most important signal of moat health is the Dollar-Based Net Retention rate, which shows whether existing customers are spending more over time.
Consistently beat revenue and EPS guidance for the last four quarters.

Founder-led with Lacerte holding a significant stake in the company.
Capital Allocation Track Record
Rene Lacerte is a proven founder-CEO who has successfully navigated Bill.com from a niche bill-pay tool into a broad financial platform. His decision to acquire Divvy for $2.5 billion in 2021 was initially questioned for its high price, but it has aged exceptionally well, now providing the company's fastest-growing revenue stream. Management has shown strong strategic judgment by prioritizing profitability in 2024, proving they can pivot from "growth at all costs" to a sustainable business model when the market environment changed.
The primary governance risk is the high degree of dependence on Lacerte’s vision, as the company's culture and strategy are deeply tied to his founder status. While there is a credible bench of executives, including a Chief Strategy Officer and CTO with deep experience, Lacerte remains the central figure in all major decisions. There is no dual-class share structure, which provides standard shareholder protections, and the board remains independent and active in overseeing the company's expansion into new financial services.
We expect revenue to grow from $1.6B in FY2026 to $3.2B in FY2031 (~14% CAGR), with EPS growing from $2.65 to $7.40 (~23% CAGR). Small businesses are increasingly moving away from paper checks toward digital payment automation to save time and reduce errors. As the payment volume on the platform grows, the cost of maintaining the software stays relatively flat, allowing more profit to be kept. EPS grows faster than revenue because Operating margin expected to reach ~28% by FY2031.
Virtual card adoption converts standard payments into high-margin revenue. As customers move from ACH to virtual cards, Bill.com's take rate multiplies without increasing its underlying costs.
International payment expansion captures lucrative cross-border transaction fees. Small businesses are increasingly global, and providing a seamless way to pay international vendors is a high-demand, high-margin service.
AI-driven automation reduces manual entry and increases customer stickiness. Using its massive transaction data to automate bookkeeping and fraud detection makes the platform indispensable for over-stretched SMB owners.
Interest rate declines reduce high-margin "float" income on customer funds. A significant drop in interest rates would remove a profitable tailwind, forcing the software business to grow faster to compensate.
Large banks or accounting software providers bundle competing tools for free. If incumbents like Intuit or major banks offer "good enough" bill-pay for free, Bill.com's customer acquisition costs will spike.
A sharp economic downturn causes small business spending and TPV to stall. Since transaction fees are a core revenue driver, a pullback in SMB spending would directly hit the company's growth trajectory.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach (price-to-earnings applied to next year's earnings) as our primary valuation framework. This fits BILL specifically because the company has reached a critical inflection point into GAAP profitability, making earnings a more reliable and clean signal of value than the revenue multiples used during its earlier loss-making growth phase.
Applying a 25x multiple to our FY2027 EPS estimate of $3.34 yields a fair value of $83 per share. A 25x multiple sits between mature fintech peer PayPal at 16x and high-growth incumbent Intuit at 33x; we believe this middle-ground position is justified by BILL's superior growth compared to PayPal and its successful "AI Agent" product launches. Our EPS basis of $3.34 matches the deterministic projection for FY2027 exactly, reflecting a 26% year-over-year earnings growth rate.
A Discounted Cash Flow (DCF) cross-check produces a fair value of $116, suggesting our $83 target is highly conservative and leaves significant room for error. Using the TTM FCF per share of $3.85 and the market's current implied growth rate of -4.8%, the disparity indicates that the market is pricing BILL for a terminal decline that contradicts its 13.5% revenue growth. Even with a higher 12% discount rate to account for competitive risks, the DCF value remains 40% higher than our primary target, confirming that $83 is a reachable mid-point.
We're assuming BILL sustains a 15% core revenue growth rate through FY2028. This is consistent with the 13.5% YoY growth reported in the most recent Q3 FY2026 results and management’s ongoing efforts to embed BILL into platforms like NetSuite and Paychex, which significantly lowers customer acquisition costs.
We're assuming the "Interest on Funds Held" segment remains a secondary but stable profit contributor at roughly 10% of total revenue. While sensitive to Federal Reserve policy, the company’s massive $10B asset base creates a structural earnings floor that provides high-margin "float" income to offset R&D spending on AI initiatives.
We're assuming free cash flow margins stabilize near 20% as the company scales its "Spend & Expense" platform. The business has already achieved GAAP profitability and TTM free cash flow per share stands at $3.85, suggesting that the "do-it-for-you" autonomous AI model is already delivering the expected operational leverage.
The biggest risk is the intensifying competition from Intuit, which could commoditize BILL's core software offering and halt new customer acquisition. If Intuit successfully locks SMBs into its own native payment ecosystem, BILL’s forward multiple would likely compress from 25x to 12x, knocking roughly $43 off the per-share fair value. Watch the "Core Revenue Growth" line for any sustained deceleration below 10% as the primary early warning sign.
Bear case ($33): Intuit aggressively bundles bill-pay into QuickBooks core, causing BILL’s core revenue growth to drop below 8%; or A "lower-for-longer" interest rate environment reduces interest income on customer funds by more than 40% annually.
Bull case ($120): Adoption of high-margin virtual cards reaches 35% of total payment volume, driving massive gross margin expansion; or AI Agents successfully automate 50% of manual AP/AR tasks, allowing BILL to command premium per-transaction pricing.

The market is leaning bullish because Bill.com creates a network effect that forces companies to stay on its payment platform. Because 7.1 million businesses already use the network, new companies join primarily to reach those existing partners. This creates a cycle where the platform becomes more valuable the more people use it.
Skeptics think that growth has permanently slowed and the company faces too much competition from faster payment alternatives. The company relies on transaction fees from businesses, but as payment technology becomes cheaper and more common, it becomes harder for Bill.com to maintain its current take rate per payment.
