Contract to Hire (C2H): How It Works, Costs, Conversion Rates, and When to Use It
Contract to hire, often shortened to C2H, is a staffing model in which a person starts in a contract role…
Payroll at enterprise scale is no longer just about paying people on time. Multi-state and federal tax compliance, a mix of salaried, hourly, and contingent workers, global entities, and deep integrations with your HCM and ERP all sit under the surface. Choosing among the top payroll companies is really about matching a provider to your operating model, not comparing feature checklists.
This guide ranks the best payroll companies and payroll service providers in the US for 2026. For each, you’ll see who it’s best for, how it’s delivered (self-serve software, managed service, PEO, or Agent-of-Record/EOR), its US and global coverage, and its pricing model, so HR and finance leaders at businesses of any size can build a credible shortlist before booking demos.
Transparency note: Compunnel publishes this guide and is itself a payroll and workforce-solutions provider. We include ourselves only where we genuinely fit (payroll and EOR/Agent-of-Record for businesses of any size) and cover every other platform on its own merits.
Every provider below was assessed against the criteria that actually matter to HR and finance buyers:
US multi-state and federal tax filing, wage-and-hour rules, and worker classification.
Support for W-2 employees, hourly and salaried staff, and contingent / contractor / 1099 populations.
Multi-country payroll and Employer-of-Record (EOR) options where relevant.
Connectivity with HCM, ERP, time-and-attendance, benefits, and (for staffing) VMS workflows.
Self-serve SaaS vs. managed service vs. PEO co-employment vs. AoR/EOR.
Cost structure, transparency, and the company size each is built for.

01
Featured
Unlike the self-serve platforms on this list, Compunnel is a managed workforce-solutions provider: payroll and EOR delivered as a service rather than software you run yourself. It works for organizations of every size, whether that’s a small business that simply wants payroll and tax compliance off its plate, a growing company scaling its team, or an enterprise managing a large, shifting population of contingent workers, contractors, and staffing-supplier talent that must be paid compliantly.
02
ADP is the default enterprise benchmark. For complex or global organizations, ADP Workforce Now and ADP Lyric HCM extend well beyond payroll into HR outsourcing, analytics, compliance, and managed services, with payroll capabilities across roughly 140 countries.
03
Paychex Flex pairs full-service payroll with strong HR support, and its PEO offering lets growing companies offload benefits and compliance. It sits comfortably between DIY software and full enterprise suites.
04
Workday is a full human-capital-management and finance platform. Enterprises adopt it to unify HR, payroll, and financials on a single data model; native US payroll is complemented by global payroll partners and connectors.
05
Dayforce (formerly Ceridian) is known for continuous calculation, so gross-to-net is always current rather than batched at period end. Beyond payroll it offers a full HCM suite covering workforce management, benefits, and talent.
06
Paycom runs on one database across HR and payroll, and its Beti tool has employees review and approve their own paychecks before submission, reducing errors and post-payroll corrections.
07
Paylocity is a cloud HCM with payroll at its core and a reputation for a modern interface and employee-engagement features, making it popular with growing mid-market HR teams.
08
Rippling connects payroll to HR, IT (device and app management), and spend in a single system, automating onboarding and offboarding end-to-end. Pricing is modular, so real costs depend on the mix of products you select.
09
TriNet is a professional employer organization (PEO): through co-employment it administers payroll, benefits, and HR compliance, giving smaller companies access to benefits and expertise usually reserved for larger employers.
10
Deel is a global-first platform combining contractor payments, global payroll, and EOR across 150+ countries. It’s the common choice for US companies that hire internationally, and it also supports US payroll.
11
Papaya Global focuses on multi-country payroll plus the payments infrastructure to actually move money to workers worldwide, with consolidated visibility and compliance across 160+ countries.
12
Gusto is the usability benchmark for small US employers: clean onboarding, automatic tax filing in all 50 states, and transparent pricing. It’s included as the SMB anchor, excellent below roughly 50 employees but not built for large-enterprise or native global-employee payroll.
The best payroll provider for your organization depends on your operating model far more than on brand size. Work through these questions before you shortlist:
Do you want software your team runs, a fully managed service, a PEO co-employment relationship, or an AoR/EOR that becomes the legal employer/payer?
A mostly W-2, single-country team points to a SaaS platform; large contingent, contractor, or staffing-supplier populations point to a managed payrolling partner.
Multi-state, multi-country, union, or heavily hourly workforces raise the bar on tax and wage-rule depth.
Your existing HCM, ERP, time system, and, for staffing, your VMS.
Base fee, per-employee rate, modules, and implementation, not just the headline number.
Self-serve help center vs. a named service team for complex, high-stakes payroll.
Most platforms on this list are engineered around your own direct employees. Compunnel takes a different approach: it runs payroll as a managed service for businesses of every size, from small companies that simply want payroll and tax compliance handled, to enterprises and staffing firms managing large contingent workforces of temporary workers, contractors, and supplier talent who must be paid accurately and compliantly.
Rather than selling you software to run yourself, Compunnel acts as a managed US payrolling partner: full-service payroll and tax compliance, worker classification, and EOR / Agent-of-Record engagements, with reach into Canada and the UK. It scales from a handful of employees to large contractor populations and slots into staffing and VMS-driven workflows where most platforms fall short.
Choose a platform when you have the in-house capacity and want to run payroll yourself. Choose Compunnel when you would rather hand payroll, compliance, and payer-of-record responsibilities to a managed partner, whether you are a small business or a large enterprise.
Talk to Compunnel’s payrolling team about payroll, EOR, and Agent-of-Record for your US operations.
Payroll software is a tool your team uses to run payroll yourself. A payroll company, like Compunnel, delivers payroll as a managed service: the provider runs it for you, and in models such as EOR or Agent-of-Record can also take on employer or payer responsibilities. Compunnel supports businesses of every size, from small companies that want payroll off their plate to enterprises with large contingent workforces; self-serve platforms suit teams that would rather run payroll in-house.
If you want payroll handled for you as a managed service across any business size, including contingent-workforce payrolling and Agent-of-Record, Compunnel is a strong first choice. If you would rather run payroll in-house, ADP, Workday, Paycom, Paylocity, and Dayforce are common picks for direct employees at scale, Gusto is the go-to for small businesses, and Deel or Papaya Global lead for global teams.
An Employer of Record (EOR) becomes the full legal employer of your workers. A PEO co-employs staff alongside your company, sharing HR and compliance responsibilities. An Agent of Record (AoR) manages and pays independent contractors compliantly without employing them. Compunnel offers both EOR and Agent-of-Record, so businesses of any size can choose the model that fits each engagement and shift the associated risk and administration off their books.
Managed-payroll providers like Compunnel, along with enterprise, PEO, and EOR options, are usually quote-based, priced on headcount, workforce complexity, and the services included, so you pay for the outcome rather than assembling modules yourself. Self-serve platforms typically charge a monthly base fee plus a per-employee rate instead. Whichever route you take, compare total cost: base fees, per-employee rates, add-on modules, and implementation.
Yes. Compunnel handles US payrolling together with EOR and Agent-of-Record for contractors, with reach into Canada and the UK, giving you a single managed partner for employees and contingent talent alike. Among the platforms, Deel and Papaya Global are built for global payroll and contractors, while Rippling and ADP extend internationally via EOR and multi-country payroll.
Start with your operating model and workforce composition, then compliance depth, integrations with your HCM/ERP (and VMS for staffing), support model, and true total cost, in that order. If you would rather own the outcome than run the software, a managed partner like Compunnel fits businesses from small to enterprise; if you have the in-house capacity, a self-serve platform may suit. The right provider matches how you actually work, not just the longest feature list.
