Gusto vs ADP vs Paychex: Best Payroll for Self-Employed Tradesmen (Solo Contractors)
When you're a self-employed tradesman – whether you're laying tile, fixing roofs, or plumbing – your focus is on the job, not paperwork. But payroll, even for just yourself or a helper, can land you in big trouble if done wrong. Messing up tax payments, W-2s, or how you classify a helper (employee vs. 1099 subcontractor) leads to penalties that stick. Picking the right payroll system early means less hassle and, more importantly, no costly mistakes that pull you away from your tools and your customers.

The Quick Answer
If you're a solo roofer, plumber, or flooring installer, mostly working by yourself or with occasional 1099 helpers, Gusto is your best bet. It's built for small teams and makes self-employment taxes easy. ADP is for when your trade business scales up, perhaps you have a crew of W2 employees across multiple job sites, and need deeply customized options. Paychex is for the busy contractor who wants a dedicated person to handle all payroll tasks, allowing them to focus entirely on their carpentry, tiling, or drywall work.
Side-by-Side Breakdown
Gusto: Starts around $40/month base + $6/person. It’s perfect for a solo electrician or painter who just needs to pay themselves, manage quarterly estimated taxes, and maybe onboard one part-time apprentice. Setup is intuitive, and it handles all the tax filings automatically. Think of it as your digital assistant for payroll.
ADP Run: Custom quotes, often $60-$200/month. This is for the drywall contractor scaling up to a crew of three W2 employees, plus multiple 1099 subs across different job sites. ADP offers extensive HR add-ons and dedicated reps, meaning it can grow with your business as you move from a single work truck to a small fleet.
Paychex Flex: Custom quotes, typically $60-$160/month. If you’re a busy tile contractor who’d rather be cutting ceramic than dealing with payroll questions, Paychex is for you. They provide a dedicated account manager who handles setup and ongoing payroll, from calculating hours for your crew to processing retirement contributions. It's hands-off payroll management.
When to Choose Gusto
Gusto is right for most self-employed tradesmen running payroll for the first time. If you're a first-time self-employed electrician or painter, Gusto makes paying yourself, paying quarterly estimated taxes, and even cutting checks for a 1099 subcontractor straightforward. Its self-onboarding process is genuinely easy. Tax filing is automated, and the system is simple to use. No need to spend hours learning complex software when you could be finishing a bathroom remodel or fixing a leaky pipe. Its included HR tools like offer letters are useful even if you just hire one W2 helper down the line.
When to Choose ADP
ADP makes sense once your plumbing or roofing business grows beyond just you and a few 1099 helpers. If your roofing business has grown to 5-10 W2 employees working across state lines on different jobs, or you're managing complex PTO for a foreman and multiple laborers, ADP’s robustness becomes valuable. It handles different pay frequencies, specific union or PTO accrual complexities, and can integrate deeply if you use other business management software. Expect a more involved sales process and custom pricing, but also dedicated support for a growing operation with more moving parts than just a single van and a single worker.
When to Choose Paychex
Paychex fits business owners who want a human to manage their payroll rather than software they manage themselves. For the busy general contractor who's always on site, running projects, and would rather pay a bit more to have a dedicated person handle every payroll detail for their carpentry crew or plumbing team, Paychex is a strong option. Their account manager model means you have a specific person to call when something goes wrong or you have a question. You can pick up the phone, explain your situation (e.g., 'Joe worked overtime on the new kitchen build, Bob took a sick day'), and have it handled without touching a keyboard. They also have solid retirement plan integration, which can be useful as your business matures.
The Verdict
For most self-employed tradesmen starting out — whether you're a solo landscaper, a flooring specialist, or a general handyman — Gusto is the practical choice. It handles paying yourself, managing 1099s for that occasional helper, and automating your taxes without breaking the bank or taking you away from your tools. Only upgrade to ADP when your complexity demands it, like managing a larger crew across multiple projects. Use Paychex if you strongly prefer a dedicated human relationship and want someone else to handle every payroll detail for your trade business.
How to Get Started
For Gusto: You can set up your account and be ready to pay yourself (or your first helper) in an afternoon. You'll need your business EIN, your state tax ID (if you have one), and your bank details. Make sure you have W-9 forms for any 1099 contractors you plan to pay. For ADP or Paychex: Request a quote online or by phone. Expect a sales call to discuss your needs. Be ready to explain your crew size – whether it's just you, a couple of W2 employees, or a mix of W2 and 1099 subcontractors – to get an accurate price.

FREQUENTLY ASKED QUESTIONS
Do I need payroll software if I am the only employee?
If you elect S-Corp treatment and pay yourself a salary, yes. If you are a single-member LLC taxed as a sole proprietor, you take owner draws and do not run payroll. Gusto handles both scenarios.
Can I switch payroll providers mid-year?
Yes, but it requires careful coordination to ensure year-to-date records transfer correctly. January 1 transitions are cleanest. Gusto makes switching relatively easy with a payroll history import tool.
What happens if I miss a payroll tax deposit?
The IRS charges penalties starting at 2% for deposits 1-5 days late, escalating to 10% or more for deposits over 15 days late. This is why software that handles deposits automatically matters.
