QuickBooks Payroll works well for most small to mid-sized contractors. If you’re already running QuickBooks for your books, the payroll module integrates directly. Labor costs flow into your accounting without manual entry, and you can assign hours to specific jobs and cost codes. That integration matters more than any individual feature.

Gusto is another solid option. It handles payroll processing, tax filings, and direct deposit with a clean interface that’s easy to use. The downside for contractors is that Gusto doesn’t integrate as tightly with job costing. You can sync it to QuickBooks, but labor costs often land in a general payroll expense account rather than hitting specific jobs automatically. If you’re tracking job profitability closely, that creates extra work.

For contractors who need job costing, the key question isn’t which payroll software is “best” overall. It’s whether your payroll system can push labor hours to the right jobs. A framing crew working on two projects in the same week needs their time split accordingly. If that data doesn’t flow from payroll into your books by job, you’re either entering it twice or not tracking it at all.

ADP and Paychex work fine for contractors who want to outsource everything and don’t mind paying more. They handle tax filings, compliance, and deposits. But the integration with QuickBooks is clunky compared to QuickBooks Payroll, and you lose some of the automation that makes contractor-specific tracking easier.

If you do prevailing wage work on government contracts, certified payroll becomes a factor. QuickBooks Desktop Payroll handles certified payroll reporting. QuickBooks Online Payroll does not, at least not without workarounds. Gusto has limited certified payroll support. For heavy prevailing wage work, contractors sometimes use specialty software like Foundation or Sage 100 Contractor that handles both accounting and payroll with built-in certified payroll reports.

Most contractors in the MetroWest area running crews of fifteen or fewer employees do fine with QuickBooks Payroll. The setup matters though. Pay items need to be configured for different labor types. Jobs need to be set up to receive labor costs. If you want to see what framing labor cost on a specific project, that structure has to exist before you run the first paycheck.

The common mistake is choosing payroll software based on price or marketing without thinking about how the data connects to everything else. Payroll that doesn’t talk to your accounting system means you’re reconciling manually. Payroll that can’t split time across jobs means your small business bookkeeping in MetroWest Massachusetts shows total labor costs but not labor costs by project. You end up knowing you spent $180,000 on field labor last year without knowing which jobs made money and which ones didn’t.

Whatever you choose, get it set up correctly from the start. Fixing payroll configuration after months of bad data is painful. Getting it right on day one takes a few hours of planning but saves headaches for years.
