Is BILL a Buy or a Sell? The Bull and Bear Case (2026)

That depends on which case you find more convincing, and both are on this page. The bull case rests on Monetization per customer, not customer count, with revenue (ttm) at ~$1.60B, up ~12% year over year. The bear case rests on float revenue, which was ~$35.4 million in the March quarter and ~$112.7 million over nine months, fell year over year as interest rates declined, and further cuts would keep pressuring a high-margin revenue line BILL does not control. Analysts covering it are spread from $42.00 to $77.00, which is itself a signal that this is genuinely contested. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.

Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. Float revenue, which was ~$35.4 million in the March quarter and ~$112.7 million over nine months, fell year over year as interest rates declined, and further cuts would keep pressuring a high-margin revenue line BILL does not control. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. The most pessimistic published target is $42.00, -12.5% from the $47.99 price, which is one analyst's downside case rather than a floor. Walnut is not an investment adviser.

Monetization per customer, not customer count. With the installed base up only ~1% year over year, nearly all of BILL's ~16% core revenue growth came from take rate and volume within existing accounts. The most optimistic analyst target on BILL is $77.00, +60.5% from the $47.99 price. That figure is only reachable if this thesis works close to its best case.

Float revenue, which was ~$35.4 million in the March quarter and ~$112.7 million over nine months, fell year over year as interest rates declined, and further cuts would keep pressuring a high-margin revenue line BILL does not control. Customer growth of ~1% year over year is the clearest structural concern, since it leaves the company dependent on take-rate expansion in a market where Intuit, Ramp, Brex, Navan and Corpay all compete aggressively on price. Card lending exposes BILL to small-business credit: the provision for expected credit losses was ~$57.6 million over the first nine months of fiscal 2026. Stock-based compensation of ~$194.3 million over nine months against ~$1.22 billion of revenue keeps GAAP profitability marginal, with trailing net income near ~$0.2 million and an accumulated deficit of about ~$1.77 billion. Convertible notes outstanding include ~$1.24 billion of 2030 notes and ~$119 million of 2027 notes, and May 2026 brought a leadership shake-up in which the chief technology officer and the head of payments and financial services departed while the president moved into a new strategy role. The most pessimistic published target is $42.00, -12.5% from the current price, which is roughly what the stock is worth if these risks bite rather than the drivers.

BILL Holdings runs a financial operations platform used by roughly 494,000 small and midsize businesses for payables, receivables, cards and expense management.

Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (Monetization per customer, not customer count) stalling in the reported numbers rather than in the narrative, the risk above (float revenue, which was ~$35.4 million in the March quarter and ~$112.7 million over nine months, fell year over year as interest rates declined, and further cuts would keep pressuring a high-margin revenue line BILL does not control) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.

BILL operates a financial operations platform for small and midsize businesses. Customers use it to capture and approve invoices, pay suppliers by check, ACH, card, real-time payment or cross-border transfer, send and collect their own invoices, and manage employee spending through corporate cards and budgets. It integrates with accounting systems such as QuickBooks, Xero, NetSuite and Sage.

Three ways. Subscription fees, ~$74.5 million in the March 2026 quarter, are fixed per user or per account. Transaction fees, ~$296.6 million, are charged per payment and include interchange on Divvy card volume. Float revenue, ~$35.4 million, is interest earned on customer funds held while payments settle, which rises and falls with short-term interest rates.

Barely, on a GAAP basis. Trailing twelve-month net income was roughly ~$0.2 million on ~$1.60 billion of revenue, and the trailing operating line remains a loss of about ~$61 million. On a non-GAAP basis, which excludes ~$194 million of nine-month stock-based compensation and restructuring, operating income was ~$79.8 million in the March quarter, and free cash flow ran near ~$383 million over twelve months.
