On 2 September, ADP reported that US private employers added 38,000 jobs in August, below July's 46,000 and below a consensus near 47,000 — the smallest monthly gain since January. Inside the number, professional and business services shed 16,000 positions while education and health services added 45,000. ADP compiles that report from its own payroll files, which are also its invoices.

That matters because the software business built on white-collar employment does not sell seats a department can add at will. Automatic Data Processing bills per pay processed for more than a million clients; Workday, whose human-capital and financial software runs at more than 65% of the Fortune 500, bills largely per worker per year; Paycom, a single-database payroll platform for small and mid-sized US employers, charges per employee per month. All three reported in the last five weeks. All three showed the meter flat — and all three found their earnings growth somewhere else.

The float, the buyback, the layoff

ADP's pays per control — its count of employees on client payrolls — grew 1% in fiscal 2026 and is guided to 0% to 1% in fiscal 2027. Employer Services revenue rose 7% to $3.7bn in the June quarter but is guided to 5-6% growth this year. New business bookings of more than $2.2bn grew 6% against guidance of 4-7% ahead, and client revenue retention of 92.1% is guided a tenth to three-tenths of a point lower. The line that actually grows is the cash ADP holds between collecting payroll and disbursing it: $1.54-1.56bn of client-funds interest is guided on an assumed 3.7% yield, up from 3.4%, on balances growing 3-4%. Chief executive Maria Black has described the backdrop as a "low hire, low fire" labor market.

Workday's July quarter brought $2.651bn of revenue, up 12.9% — the third straight quarter of deceleration. Its 12-month subscription backlog grew 14.2%, but total subscription backlog of $27.4bn grew 8.0%, against 17.6% a year earlier, and early fiscal 2028 subscription growth was framed at about 11% versus the 13.9% just reported. Non-GAAP operating margin reached 31.1% on headcount held flat near 20,900, a $5bn buyback closed six months early and a fresh $4bn was authorized. "This is Workday's moment, I have never felt better about where we are headed," chief executive Aneel Bhusri told investors on the August 27 call, pointing to roughly $600m of artificial-intelligence recurring revenue and more than $100m of new annual contract value from AI products. Only 200 customers signed paid AI credit contracts in the quarter.

Paycom is the exception worth naming. Revenue grew 9.8% to $531.2m, an acceleration from 7.8%, with recurring revenue up 11.0%. But management described client employment growth as stable, with no acceleration; the earnings came from adjusted EBITDA margin of 44.2%, up 3.2 points, after the company cut roughly 500 Oklahoma jobs it said AI had automated, and from retiring a fifth of its shares this year — diluted share count fell to 45.9m from 56.3m. "Our strong second-quarter results came in ahead of expectations, reflecting the strength of our automation strategy and disciplined execution," founder-chief executive Chad Richison said in the August 5 results release.

What the shares did

All three bottomed on the same session, 10 April, and have since risen 83%, 112% and 50% respectively — a common trough rather than three company turns. The advance was no grind: Paycom gapped 23.8% on 6 August on roughly five times normal volume, and Workday gapped 12.5% on 14 August on a report that Silver Lake was in talks to take it private, before its own numbers. Across the wider back-office software group, the largest thirty-day gainer is Atlassian at 69%, a developer-tools vendor, while BILL and monday.com are flat.

The verdict

Margin expansion, float interest and share retirement are real earnings, and Paycom's 11% recurring growth is real demand. What none of the three has produced is evidence that the headcount they invoice is turning. ADP now carries the highest forward multiple of the three, 23.1x against 25.8x trailing, on the slowest guided growth; Workday trades at 7.02x trailing gross profit against 4.31x in early May; Paycom, at 19.9x forward versus 25.5x trailing, is the cheapest of the three on cash flow. The likelier reading of August is a rotation out of AI hardware into beaten-down software, with a takeover report doing the rest.

The uncomfortable symmetry is that all three are expanding margins the same way their customers are: by employing fewer people. Workday is holding headcount flat with its own AI; Paycom automated 7% of its workforce away. Every dollar that strategy saves them is a dollar off somebody's pays per control.
