A plant pays a large hourly, clocked workforce across shifts — so the paycheck is only as accurate as the time data behind it. Get shift pay, overtime or union rules wrong and you are re-running payroll every period. We reweighted the rubric around time and attendance and workers' comp, then ranked seven in plain English — and said clearly when the small, cheap option is the right one.
Same five criteria, retuned for the shop floor. Time and attendance leads, because shift differentials, overtime and union pay are only as right as the clock feeding them. Workers' comp and multi-state follow, since injury rates and pay-as-you-go premiums are a real line item here. A pretty interface matters least when 200 people clock in on a tablet.

Rippling
Best for shift-based hourly plants
Rippling puts the thing manufacturing lives on — accurate hourly pay from the clock — at the centre rather than the edge. Time and attendance, scheduling, shift differentials and payroll sit on one employee record, so a night-shift clock-in turns into correct pay with no re-keying, and you can add device and IT management for a plant that also runs an office. The modular pricing climbs as you switch modules on, and it is more system than a ten-person shop needs. For a growing multi-shift plant, little else fits this cleanly.
When a plant is large and heavily unionized, ADP's depth is hard to beat: decades of collective-bargaining handling, garnishments, multi-state tax and workers' comp experience, with a service tier for every size from RUN up to Workforce Now. That depth is exactly what a 400-person unionized site needs. The cost is quote-only, and the experience feels more corporate and less modern than Rippling — which is why it sits second here, not first, unless union complexity is your daily reality.
Paychex pairs a published entry price with a dedicated payroll specialist and — the part that matters for a plant — pay-as-you-go workers' compensation, so premiums track real payroll instead of a lump-sum estimate. That suits an owner who would rather hand the whole thing off, comp included. The platform is capable but dated next to Rippling, and time and attendance is an add-on module rather than the heart of the system, so confirm the shift-differential setup before you sign.
For a small machine shop or a single-site manufacturer with simple schedules, Gusto is the smart-money pick: full tax filing in all fifty states, a calm interface a first-time admin can run, and time tracking that flows into payroll once you are on the Plus plan. Where it thins out is deep shift-differential rules, heavy union work and workers' comp at scale — the daily load of a multi-shift plant. Below roughly fifty hourly staff on straightforward shifts, it is more than enough; above that, you will feel the ceiling.
BambooHR is the HR system of record people actually enjoy — strong on employee files, onboarding, performance and safety-training records, which a plant genuinely needs to track. But payroll is a US add-on rather than the main event, and it is not built to run complex shift differentials and overtime for a large clocked floor. Pair it with a dedicated payroll engine and it shines as the HR layer; lean on it for shift payroll and you have bought the wrong half of the problem.
The PEO model bundles payroll, benefits and workers' compensation under one flat per-employee fee — and in a higher-injury trade, offloading comp and getting access to large-group benefits is a real draw for a small plant. The trade is configurability: Justworks is not built for intricate shift differentials or heavy union rules, and the benefits-driven cost runs far above the platform fee alone. A fit for a lean, mostly-standard-shift shop that wants big-company benefits, not for a complex multi-shift operation.
Deel is excellent at global and contractor payroll — and the wrong tool for a domestic plant. The word "contractor" here means international independent workers, not your line staff, and there is no shift-differential engine, no pay-as-you-go workers' comp and no union machinery. We list it only so the branding does not fool you: unless you are hiring workers overseas, a US manufacturer does not need it. Powerful, just aimed somewhere else entirely.

The verdict
For most multi-shift plants, run Rippling — native time and attendance, scheduling and payroll on one record is exactly what a clocked hourly workforce needs, and it kills the re-keying that causes payroll errors. If your site is large and heavily unionized, ADP is the safer pick for its collective-bargaining and workers' comp depth. Want the whole thing handed off, comp included? Paychex and its pay-as-you-go workers' comp is the answer. And a small single-site shop should not over-buy — Gusto on Plus does the job for far less.
Here is the trap in plain terms: a plant's payroll is only as accurate as its time clock, so any tool that treats time and attendance as an afterthought will cost you on the shop floor — in re-run payrolls, grievance disputes and comp true-ups. An HR-first system or a simple PEO can look polished and still miss shift differentials and complex overtime. And do not be misled by branding: Deel's "contractor" payroll is for international workers, not your line. Match the tool to how your floor actually clocks in, staff it around your shift and union reality, and revisit the day you add a second shift or a union.

Questions manufacturers ask
What is the one feature we actually need?
Time and attendance that feeds payroll directly. A plant pays a large hourly, clocked workforce, so the paycheck is only as accurate as the clock data behind it. You need shift differentials — extra pay for nights and weekends — overtime that follows the real FLSA rules, and, if you are unionized, the correct fringe and dues. When the time clock and payroll are separate systems that do not talk, errors and re-runs are guaranteed.
Does Gusto work for a manufacturing business?
For a small machine shop or single-site manufacturer, yes. Gusto files taxes in all fifty states and, on the Plus plan, includes time tracking that flows into payroll. It runs thin on deep shift-differential rules, complex union work and workers' comp at scale — the daily load of a large multi-shift plant. Below roughly fifty hourly staff on simple schedules it is a sensible, affordable choice; above that, Rippling or ADP earn their cost.
Why does Rippling rank above ADP here?
Because accurate hourly pay from the clock — the thing manufacturing lives on — is Rippling's core, not a bolt-on. Time and attendance, scheduling, shift differentials and payroll sit on one record, so a night-shift clock-in becomes correct pay with no re-keying. ADP is the better answer for large, heavily unionized plants where collective-bargaining depth and workers' comp experience outweigh a modern interface. Both are excellent; the choice is size and union complexity.
What is the wrong-fit trap?
Buying a tool that treats hourly time and attendance as an afterthought. An HR-first system or a PEO can look polished, but if it cannot handle shift differentials, complex overtime and pay-as-you-go workers' comp cleanly, your plant floor pays for it. The sharper trap is a global-payroll tool like Deel, whose "contractor" features are for international independent workers, not a domestic shift-based plant.
