BILL vs SAP: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: BILL is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. BILL and SAP share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined BILL and SAP exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

BILL Holdings, Inc. sells the software that small and midsize businesses use to run money in and money out. The core BILL AP/AR product handles invoice capture, approval routing and payment execution across checks, ACH, cards, real-time payments and cross-border rails, while BILL Spend and Expense (the former Divvy business) issues corporate cards and enforces budgets. A third channel, Embedded Solutions and Other, distributes the same plumbing through accounting firms, financial institutions and software partners. Revenue arrives in three shapes: fixed subscription fees, transaction fees (including interchange on card volume), and interest earned on customer funds sitting in transit. For the March 2026 quarter, subscription fees were ~$74.5 million, transaction fees ~$296.6 million and float revenue ~$35.4 million, adding to total revenue of ~$406.6 million. The platform moved ~$88.7 billion of payment volume across ~34.0 million transactions in that quarter, about 12% and 14% above the prior year respectively.

SAP SE is a German enterprise-software company and one of the world's largest ERP providers, whose systems form the operational backbone of many of the biggest corporations and public-sector organizations. Its products span finance, supply chain, procurement, human resources, spend management, and analytics, anchored by the S/4HANA ERP suite and delivered increasingly as cloud services. US investors typically access SAP through its NYSE-listed ADR under the ticker SAP; the underlying ordinary shares trade in Frankfurt.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• BILL drivers: Monetization per customer, not customer count; Operating leverage and the buyback.
• SAP drivers: Cloud transition and recurring revenue; Cloud ERP Suite momentum.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: 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. For SAP, the main risk is expectations: SAP trades as a high-quality compounder, so a slowdown in cloud growth, backlog, or margin progress could weigh on a valuation that already prices in successful execution.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick BILL if you believe its drivers more; SAP if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the BILL and SAP guides.

BILL. Valuation looks very different depending on which earnings number is used. On GAAP net income, which is essentially breakeven on a trailing basis, no meaningful multiple exists; on guided fiscal 2026 non-GAAP earnings of ~$2.61 to ~$2.64 per diluted share, the stock sits around ~18x, and on forward consensus estimates closer to ~15x. Cash and short-term investments of roughly ~$2.2 billion against ~$1.9 billion of largely zero-coupon convertible debt leave enterprise value slightly below market cap, so the ~2.8x EV/sales figure is the cleanest cross-company comparison.

SAP. Figures are approximate, reported in euros, and tied to the asOf date; verify live numbers before acting. SAP typically trades at a premium software valuation that reflects its entrenched ERP position and improving cloud economics, so the earnings multiple leans on continued cloud growth and margin expansion. Because it is an ADR, US-dollar returns also depend on the euro-dollar exchange rate, which can add or subtract from the underlying business performance.

Headline figures (approximate, August 2026): BILL shows market cap ~$4.8B (shares near ~$48, ~99.6M outstanding), revenue (ttm) ~$1.60B, up ~12% year over year, q3 fy2026 revenue ~$406.6M total, ~$371.1M core (+16% YoY), profitability GAAP operating loss ~$61M TTM; non-GAAP operating income ~$79.8M in Q3 FY2026; SAP shows total revenue (q1 2026) ~9.6 billion euros, up ~12% at constant currencies, cloud revenue (q1 2026) ~5 billion euros, up ~27% at constant currencies, current cloud backlog ~22 billion euros, up ~25% at constant currencies, cloud erp suite growth Growing faster than overall cloud (reported around 30%+ range).

BILL and SAP are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined BILL and SAP exposure against your real portfolio. It is not an investment adviser.
