Industries · Federal service contractors
Built for the Service Contract Act. Not against it.
Doyel Labs builds software for the operator who runs a USPS route, a base service contract, or any federal award where the payroll needs to hold up to a DOL inspection. Every stub carries the wage determination. Every draft passes the day-rate floor. Every rate change lands in an audit row your inspector can read.

Who this is for
Operators of federal service contracts.
Anyone who has to pay day-rate independent contractors on a federally awarded service contract and needs to prove SCA compliance to the Department of Labor. Especially:
USPS route contractors
Base service contractors
GSA / Schedule holders
Subcontractor operators
1099 shops going W-2-adjacent
Post-award compliance ops
Why this is hard
Off-the-shelf payroll isn't built for the SCA.
Gusto, ADP, QuickBooks, and Rippling are built for W-2 employees on straight-time hourly wages. Federal service contracting has three quirks they don't handle cleanly:
01
Day rate, not hourly
SCA workers on service contracts are usually paid by the day, not by the clock. But the day rate has to clear an 8-hour equivalent at the WD-mandated base wage plus H&W fringe. Off-the-shelf systems can't do that check.
02
Per-county wage determinations
The applicable wage determination is county-specific and revised without notice on SAM.gov. Off-the-shelf systems don't look up your WD — you're expected to hand- type numbers that change every year.
03
DOL audits, not IRS ones
The inspection risk is a DOL audit for SCA compliance, not an IRS payroll-tax audit. The record set they want is different: WD numbers, county mapping, H&W fringe itemized, per-stub floor check.
What we build for you
A payroll workspace that speaks SCA natively.
We ship a per-operator workspace, deployed to your own domain, with the following features already implemented on our current live operator (SteadFast Transportation Inc.). Every item below exists in real code, not on a roadmap slide.

Day-rate floor enforcement
(base wage + H&W) × 8 and refuses to issue a stub below that floor. The whole check is on the stub.Per-contractor register
Batch pay runs

On your domain
yourcompany.com/payroll (or a subdomain). Your logo, your typography, your contractor list — nothing branded Doyel Labs on the operator-facing UI.The audit trail
What a DOL inspector actually reads.
The audit log is the whole point. When an inspector asks for the pay records, you export a CSV, hand them a stub PDF for any contractor + period, and point at the WD number on the header. Nothing is hidden behind an accountant.

In practice
Live on a USPS route contractor since 2026.
SteadFast Transportation Inc. operates federally awarded USPS contract-delivery routes across rural Montana and North Dakota. Doyel Labs built their marketing site, their SCA-first payroll workspace, and the plumbing that ties them together — shipped in about six weeks.
Doyel Labs exceeded our expectations. They took the time to understand our business and delivered a site that looks exceptional and functions far better than we imagined.

Scope discipline
What SCA payroll from Doyel Labs does not do.
We ship a compliance and record-keeping workspace, not a full-service payroll processor. Read this before you compare us to ADP.
No tax filing
No money movement
Start a build
Tell us the contract and the counties.
Email us the contract type (HCR, RCR, GSA schedule, base service, etc.), the counties your contractors work in, and a rough headcount. We reply within one business day with a scope and a fixed price.
Doyel Labs is US-based, in Casper, Wyoming. Every server we run for you sits on US infrastructure by default. If your award requires a specific data-residency posture, tell us in the first email; we can build to it.
Not a federal contractor?
We still probably build for you.
This page is deep because SCA payroll is our current wedge — it's where we have live client work — but Doyel Labs is industry-agnostic. We build custom software for professional services, transportation, family-owned shops, e-commerce, real estate, nonprofits, healthcare admin, hospitality, and anyone else with an operation software can improve. Have a look at the full list, or tell us your industry directly.
Doyel Labs is not a federal-benefits administrator, not a payroll processor, and not a money transmitter. Every dollar amount above is illustrative; the DOL wage determinations linked in the app come directly from SAM.gov.
