Zeni: the accounting firm you can trust
With Zeni, you get more than accounting. On top of our bookkeeping, tax, and advisory business services, we provide a suite of essential financial products, including business bank accounts, credit cards, bill payment tools, and employee reimbursement software.
Instead of juggling multiple vendors, Zeni lets you manage all your financial operations from a single platform, and our AI-powered automation and expert support keeps everything integrated and running smoothly.

Denver CPA and tax accountants
Colorado’s tax environment may be business-friendly, but Denver businesses still have their share of challenges to navigate, such as the single sales factor apportionment rule, which can both complicate tax calculations and increase taxes for multi-state sellers.
Zeni handles these complexities for you. Our experts stay ahead of changing tax laws, ensuring compliance and uncovering opportunities to reduce what you.
We’ve already helped clients claim more than $6.5 million in R&D tax credits alone, and our expert tax accountant team can find similar opportunities for your business to help fuel growth.
Less time on your books, more time above 14,000 feet

Bookkeeping services
Good bookkeeping requires speed and precision, and Zeni delivers both in spades. Not only does our AI-powered platform provide real-time financial data, but it can also automatically perform a GAAP-compliance audit to help ensure accurate reporting.
However, no technology is a complete solution on its own. That’s why we pair our cutting edge automation with a dedicated team of human experts. With Zeni, you can rely on your small business accounting team to provide support when you need it.
With $1.3 billion in transactions already processed every month, our system is built to scale. Partner with Zeni for virtual bookkeeping services that will help you grow.


Fractional CFO services
By the time your business is well-established, good bookkeeping and tax compliance become table stakes. You’ll eventually face even more complicated financial challenges, like venture capital investor pitches and business valuation negotiations.
That’s where our fractional CFO services come in. With executive-level experience, they provide high-impact strategic business planning—without the cost of a full-time professional.
Since our business advisory services also integrate with our tax preparation and bookkeeping, our CFOs also have a uniquely deep and holistic insight into your finances, allowing them to provide better-informed guidance.
Industry expertise
Your business deserves better service than a generic Certified Public Accountant can provide. In a startup ecosystem as innovative and competitive as Denver’s, you need an equally dynamic financial partner.
Having scaled and sold two successful startups before building Zeni, our founders know what it takes to grow. That’s why we go beyond basic public accounting, delivering real-time data and expert strategic guidance through a seamlessly integrated platform.
Team up with Zeni for outsourced accounting services that can grow with your business as it develops, from seed funding to late-stage expansion.
