Engineering & Professional Services Firms: Payroll Software vs. Managed Payroll Service (2026)
Engineering firms evaluating payroll options typically compare managed payroll service against payroll software. Here is the honest comparison.
Managed payroll service (like BEG) means a provider processes payroll for you. You submit hours and changes; they handle the rest including tax deposits, compliance, and year-end forms.
Payroll software (Gusto, ADP Run, Paychex Flex) means you run payroll yourself using a platform. You are responsible for configuring it correctly and keeping up with compliance changes.

| Payroll Task | Managed Payroll | DIY Software |
|---|---|---|
| Prevailing wage for government projects setup | Configured for you | You configure |
| Tax deposits | Handled | You are responsible |
| Compliance updates | Applied automatically | Your responsibility |
| Multi-state filing | Included | Varies by plan |
| Year-end W-2s | Included | Included or add-on |
| Payroll errors | Provider corrects at cost | Your cost to fix |
| New hire onboarding | Handled | You set up |
