Your financial team shouldn’t
feel like outsiders

We’re not your typical accounting firm. Our virtual CFO model gives you an entire financial team that actually feels like part of yours—because we are.

Business owners need a vested advisor

You already have enough people sending invoices and disappearing until next tax season. What do you actually need? A financial partner who picks up the phone. Someone who translates your numbers into tools you can actually use. A team that knows your business well enough to spot problems before you do.

That’s not traditional accounting. That’s what we built PrimeNumbers to be.

HOW WE’RE DIFFERENT

Your team, not your vendor

When you call us, you’re not getting shuffled around to different departments. You’re talking to your team—the same people who know your business inside and out. We don’t operate in silos because your business doesn’t work that way.

INSIGHT YOU CAN USE

Forget those 10 MB PDF financial reports that sit unopened in your inbox. We deliver key performance indicators (KPIs) on scorecards that give real-time data on the overall health of the business, allowing decision makers to gain clarity and make data driven decisions versus relying on guesswork.

BUILT AROUND YOU

Our virtual CFO model is completely customizable. Whether you need full bookkeeping, strategic planning, cash flow management, or all of the above, we build your package during discovery. No forcing you into services you don’t need.

PROACTIVE APPROACH

We anticipate what you need before you ask. Tax planning happens throughout the year, not just at filing time. Financial guidance comes before big decisions, not after. That’s what happens when your financial team is actually invested in your success.

We speak your industry’s language

We’re not generalists trying to serve everyone. We focus on industries where we can deliver real value—because understanding your business model matters.

One model. Your entire financial operations.

Our virtual CFO model brings everything under one roof—and under one team that actually communicates with each other (and with you). You pick what you need. We build it during discovery. Then we deliver it consistently, transparently, and with the kind of communication you’d expect from your own team.

Strategic insights you can actually use

Your business decisions deserve to be informed by real expertise, not generic advice. Here’s the kind of forward-thinking guidance that helps business owners stay ahead of the curve.

The SEC may rescind its climate rules. What should private companies do now? 

The SEC may rescind its climate rules. What should private companies do now? 

The SEC may rescind its 2024 climate disclosure rules, but private companies should not assume their reporting obligations disappear. Contracts, state laws, and business relationships may still require climate and emissions information regardless of what the SEC does. Here is how to assess what still applies to your company and what you can safely scale back.
Divorce and your tax return: what the settlement may not resolve

Divorce and your tax return: what the settlement may not resolve

A divorce settlement divides assets and establishes legal rights, but it does not resolve every tax question that follows. Filing status, child-related benefits, property basis, retirement transfers, and prior joint return liability all require a separate tax review. Understanding where the settlement ends and tax law begins can help you avoid costly surprises after the divorce is final.

Form 990 filing mistakes that can undermine your nonprofit’s credibility

Form 990 is more than a tax return; it's a public document that donors, grantmakers, and regulators use to evaluate your nonprofit. Common mistakes in filing, reconciliation, and narrative disclosures can raise questions about financial stewardship or put your tax-exempt status at risk. This article outlines the key errors to avoid and how to build a more reliable year-over-year filing process.
