On August 19, Bill Holdings (NYSE:BILL) reported fiscal fourth-quarter results that doubled as an argument for its own reinvention. Core revenue climbed 16% year over year to $400.5 million, but the more telling number was how much of that fell to the bottom line: non-GAAP operating margin expanded 860 basis points to 23%. The bigger story is what’s driving it. More than 175,000 businesses now run financial tasks through Bill’s AI agents, and the company is betting that figure becomes the core of the business rather than a side feature.
The Robots Are Already Working
The adoption numbers are hard to wave away. More than 40,000 organizations now use Bill’s W-9 agent, which has collected over 240,000 forms without any manual customer work, handling IRS validation end to end. Its invoice coding agent, live since February, is used by over 60,000 companies and strips out roughly 90% of the coding steps on a multiline invoice. A touchless transactions agent, generally available since April, has already automated more than 7 million transaction fields for 30,000 customers. These aren’t demos; they’re workflows customers have already switched over to.
That adoption is starting to show up in the numbers that matter to shareholders. Non-GAAP net income jumped 53% year over year to $94 million, and management expects GAAP net profit above $125 million in fiscal 2027, a threshold the company has never comfortably cleared before. Stock-based compensation is set to fall to 10% of revenue from 14%, and restructuring moves already delivered about $110 million in gross savings. Cross-selling is working too. Customers using both accounts payable and Spend & Expense tools grew 35% year over year, and that combined group posted 111% net revenue retention. Bill is also using its own data to underwrite differently; an AI model lifted invoice financing volume and revenue about 30% in fiscal 2026 while cutting expected loss rates by more than half.
Cracks Beneath The New Structure
The same restructuring producing those savings is also disrupting growth. Bill added just 1,800 net-new customers in the fourth quarter, well below its recent pace, a result management tied directly to exiting sales staff earlier than planned so the remaining team could learn its new territories. Supplier Payments Plus, the company’s push into large-scale receivables automation, has fallen short of its own targets. CEO René Lacerte said “the early progress has not met our initial expectations,” and while committed payment volume from early adopters has reached nearly $800 million, the enterprise sales motion behind it is still new. The bank channel is being reshuffled too, with management consolidating custom partner integrations onto its Embed 2.0 platform and acknowledging it does “not expect that every existing bank channel relationship will carry forward.”
Margins tell a mixed story depending on where you look. The accounts payable and receivable take rate contracted half a basis point as larger, ACH-heavy customers diluted the mix, even as total payment volume beat expectations. On the Spend & Expense side, CFO Rohini Jain flagged a “dynamic environment regarding card acceptance that may impact a small number of merchants,” and the company is renegotiating reward-tier contracts after a concentrated group of customers pushed payouts higher. Guidance bakes in some of that caution. Fiscal 2027 core revenue growth is guided to 11% to 14%, down from the 16% just reported, with three points of headwind coming from card dynamics and the bank channel shift, and management pointing to the second quarter as the likely low point for growth.
What The Market Is Pricing
Hedge fund ownership slipped from 49 funds to 48 heading into this report, a mild pullback rather than a rush for the exits. Short interest sits at 13.77% of the float, a level that points to a meaningfully sized bear camp betting against the stock. Yet the forward price-to-earnings ratio of 14.29, as of August 28, looks inexpensive for a company guiding to double-digit revenue growth and expanding margins.
The Bet Bill Is Making
Bill Holdings is trying to prove that AI agents and a leaner structure can turn a payments company into a profitability story without losing its growth edge. The bull case rests on adoption numbers that are already large and still climbing, plus margins that finally moved in the right direction. The bear case rests on a sales reset that visibly slowed new customer growth and a bank channel shrinking on purpose before it can grow again.
