Rippling vs Gusto for Federal Contractors and SCA Pay

If your contracts are subject to the Service Contract Act, the contract incorporates a Department of Labor wage determination that sets minimum hourly wage rates and fringe benefit requirements by occupation and locality, so confirm which determination applies to each labor category.

Before setting up pay rates in either platform, map every employee working on an SCA-covered contract to their correct labor category and the applicable wage determination for where the work is performed. This mapping is a contracts and compliance task first; the payroll platform then needs to hold and apply the resulting rate correctly, which both Rippling and Gusto can do once the rate is confirmed.

SCA wage determinations often specify a required fringe benefit dollar amount per hour, which contractors can satisfy either through actual benefits (health insurance, retirement contributions) or through additional cash wages if the benefit value isn't otherwise met. Getting this wrong, paying the base wage without meeting the fringe requirement, is a common compliance gap.

Document how each employee's fringe obligation is being satisfied, whether through your standard benefits plan or supplemental cash, and confirm the combined value actually meets the wage determination's fringe rate, not just the base hourly rate.

DCAA standards require employees to record time daily, to the specific contract or task order they worked on that day, with no batch entry after the fact and a documented process for correcting an error rather than simply overwriting it. This is timekeeping discipline more than a payroll platform feature, but the payroll system needs to receive accurate time-by-contract data to charge labor costs correctly.

A payroll platform's basic time tracking typically isn't built for the timekeeping controls and auditability DCAA expects, so most government contractors run a dedicated timekeeping tool that integrates with payroll; confirm each vendor's current capabilities with your DCAA-experienced accountant.

DCAA standards expect timekeeping that meets these conditions:

• Employees record their time every day, not in a batch at the end of a period.
• Each entry names the specific contract or task order the employee worked on that day.
• No entries are made after the fact, so the record stays contemporaneous and auditable.
• Errors are corrected through a documented process instead of being overwritten.

Employees working on classified contracts need an active security clearance at the appropriate level, and clearance status can change, an investigation pending, a clearance suspended, in ways that directly affect whether someone can be billed to a given contract at all that pay period.

Rippling's HRIS side can hold clearance level and status alongside an employee's profile, useful for a facility security officer or program manager confirming eligibility before assigning someone to classified work. Gusto doesn't have a dedicated field for this, so contractors on Gusto typically track clearance status in a separate system and coordinate manually with payroll and project assignment.

A small contractor with one or two SCA contracts and straightforward labor categories can build this discipline internally with a well-documented process, using either platform for the underlying pay run. A contractor managing many contracts, multiple wage determinations, and clearance-sensitive staffing is taking on enough compliance surface area that dedicated support matters more than which payroll platform sits underneath it.

ADP TotalSource can help with the HR administration layer, benefits and standard compliance, but SCA wage determination mapping and DCAA timekeeping specifically usually still need a government contracts specialist or dedicated compliance staff regardless of which platform or PEO you choose.

SCA wage determinations get updated periodically, sometimes annually, and a contract's incorporated determination can be superseded by a new one during a multi-year contract's option period, which means the minimum wage and fringe rate your labor categories were compliant against at contract start can change partway through performance.

Building a recurring check into your contracts administration process, tied to each contract's option period renewal date, catches a wage determination update before it becomes a compliance gap discovered during a DCAA audit instead, which is a materially worse way to find out.
