Pay-As-You-Go Workers' Comp Insurance: Buy Through a Broker, Not Your Payroll Provider

One of the most common questions we get from contractors across California, Nevada, Utah, Arizona, and Texas is some version of this: "If I want pay-as-you-go workers' comp billing through my payroll provider, doesn't that mean I have to buy the workers' compensation policy through them too?"

The short answer: no. You can purchase your workers' compensation insurance through an independent broker like Altamira and still use your payroll provider — Paychex, ADP, Gusto, QuickBooks Payroll, Rippling, or others — to handle pay-as-you-go billing. You don't have to give up personalized broker service to get the administrative benefits of PayGo.

What Is Pay-As-You-Go Workers' Comp?

Traditional workers' comp policies are billed on estimated annual payroll. You pay a deposit up front, then a monthly or quarterly installment based on what you think payroll will be for the year. At year-end, the carrier audits your actual payroll and either bills you for the shortfall or refunds the overage.

For contractors, that audit-true-up cycle is where things go sideways. Payroll fluctuates with seasonal work, big jobs land mid-policy, and one busy quarter can produce a five-figure audit bill nobody planned for.

Pay-as-you-go (PayGo) flips the model. Instead of estimating, the carrier pulls your actual payroll from each pay run and calculates premium against the real number, in real time. You pay exactly what you owe, when you owe it.

The Misconception: "I Have to Buy Through My Payroll Company"

This is one of the most common ways contractors get steered into the wrong workers' comp policy. A payroll rep pitches monthly payroll-based billing as something only their bundled product can offer, and the business owner — not knowing any better — buys the policy from the payroll company just to get that billing convenience. It happens constantly.

Paychex, ADP, and other payroll providers do sell their own workers' comp products, and they market PayGo aggressively as a benefit of bundling. That's where the confusion comes from. Business owners are sold on the idea that pay-as-you-go is a Paychex-only feature, and that buying elsewhere means going back to estimated annual premium and big audit bills.

It's not true. PayGo is a billing method, not an insurance product. Most major workers' comp carriers — Travelers, The Hartford, AmTrust, Employers, ICW Group, Berkshire Hathaway GUARD, and others — offer pay-as-you-go billing as a standard option, and they integrate directly with the major payroll platforms. You get the same monthly payroll-based billing whether you buy from a broker or from your payroll company. The difference is what you get around the billing — broker advocacy on classification, claims, and renewals vs. a payroll-company call center.

How It Actually Works

1. Your broker places the policy. Altamira shops the workers' comp market, finds you the right carrier for your trade and class codes, and binds coverage.
2. You elect PayGo billing at issuance. The carrier sets the policy up for pay-as-you-go and provides credentials or an integration code that links to your payroll provider.
3. Your payroll company sends actual wages each pay period. Paychex (or whoever runs your payroll) transmits the data automatically — no manual reports.
4. The carrier calculates and pulls premium per pay run. Premium is debited from your business account in line with payroll, typically via ACH.
5. Year-end audit becomes a formality. Because the carrier has been billing on real numbers all year, the audit usually nets to zero or close to it.

Why Contractors Specifically Benefit

• Seasonal payroll swings stop hurting cash flow. A slow January no longer means you're prepaying premium on summer-level payroll.
• Audit surprises go away. Most contractors who switch to PayGo never get another five-figure audit bill — the only adjustments tend to be small reclassification corrections.
• No manual payroll reports. If you've ever filed monthly self-reports for an assigned-risk policy, PayGo eliminates that paperwork entirely.
• Adding or terminating employees is automatic. Whoever's on your next payroll run is reflected in your next premium calculation.
• Better fit for 1099 / W-2 mix. When you bring on temporary W-2 crew for a big job, premium scales with them and back down when the job ends.

What You Keep by Using a Broker

Buying through an independent broker — not the payroll company — preserves the things that actually matter when something goes wrong:

• Market access. A broker shops 10+ carriers; a payroll company typically writes through one or two captive markets.
• Class code advocacy. Workers' comp premium is hugely sensitive to classification. A specialist broker fights for the right code; a payroll company tends to use whatever the carrier auto-assigns.
• X-mod review. Your experience modifier directly affects rates. Brokers review it for errors annually — payroll companies generally don't.
• Claims help. When a claim hits, you call your broker. Try getting personalized claims advocacy from a payroll provider's call center.
• One-stop COIs. When all your coverage lives with one broker, you get a single certificate of insurance covering GL, auto, workers' comp, and umbrella in one document — issued the same day. Splitting workers' comp out to a payroll company means chasing a second COI from a separate source for every project, every additional insured request, and every renewal.
• Bundled coverage. Most contractors carry GL, auto, umbrella, and bonds alongside workers' comp. Keeping it all under one broker means one renewal cycle, one COI source, and consistent advice.

Which Payroll Providers Integrate With PayGo?

Pretty much all the major ones. The most common integrations we see with our carriers:

• Paychex (Pay-As-You-Go / Workers' Compensation Payment Service)
• ADP (Pay-by-Pay)
• Gusto
• QuickBooks Payroll
• Rippling
• Patriot, OnPay, Square Payroll, and others depending on the carrier

If you're already running payroll through any of these, the odds are very high we can set up PayGo on your existing or new policy.

Common Questions

Does PayGo cost more than traditional billing?

No. There's typically no premium surcharge for using PayGo — some carriers actually offer a small discount because they get paid faster and have lower audit-collection risk.

What if I switch payroll providers mid-year?

You re-link the policy to the new provider. Your broker handles the carrier-side paperwork and there's no impact on your coverage.

Do I still have an annual audit?

Yes — every workers' comp policy is audited at year-end regardless of billing method. The difference is that with PayGo, the audit usually confirms what was already paid rather than producing a big additional bill.

Can I switch from traditional billing to PayGo on my current policy?

Often, yes — at renewal, and sometimes mid-term. Ask your broker; it depends on the carrier.

Pay-As-You-Go Workers' Comp for Contractors in CA, NV, UT, AZ, and TX

Altamira specializes in workers' compensation insurance for contractors across California, Nevada, Utah, Arizona, and Texas — including general contractors, electrical, plumbing, HVAC, roofing, painting, tile and marble, and fiber and networking subcontractors. We work with carriers that support pay-as-you-go billing through every major payroll platform, so you get the right policy for your trade and class codes and the cash-flow benefits of premium that scales with actual payroll.

State-specific notes worth knowing:

• California: Workers' comp is mandatory for any contractor with employees under CSLB rules. PayGo is widely available and especially valuable given California's high X-mod sensitivity and audit scrutiny.
• Nevada: Required for licensed contractors with employees through the NSCB. PayGo works with most private NV-admitted carriers.
• Utah: Required by the Utah Labor Commission for nearly all employers. PayGo is fully supported by the major contractor markets writing in Utah.
• Arizona: Required under ICA rules. PayGo billing pairs well with the seasonal payroll swings common in Phoenix and Tucson construction.
• Texas: Workers' comp is technically optional in Texas, but most GCs and commercial clients require it. PayGo is a popular choice for non-subscribers transitioning into voluntary coverage.

The Bottom Line

You don't have to bundle workers' comp with your payroll provider just to get pay-as-you-go billing. Buy the policy through an independent insurance broker who specializes in contractor coverage, then turn on PayGo through Paychex, ADP, Gusto, QuickBooks Payroll, or whichever payroll system you already use. You get the best of both: a real broker who advocates for you on classification, claims, and renewals — plus the cash-flow and audit benefits of premium that scales with actual payroll.

Altamira works with carriers that integrate with every major payroll platform. If you'd like a workers' comp quote that supports pay-as-you-go billing for your contracting business in CA, NV, UT, AZ, or TX, request a quote online or give us a call.
