Vertex sells tax software that helps big companies calculate, collect, and file sales taxes and other transaction taxes across thousands of rules that change constantly.
Vertex, Inc. is a tax technology company. It sells software that handles a specific, painful job: figuring out the right sales tax, value-added tax, and similar transaction taxes on what a company sells, then collecting that money and filing the returns. In the United States alone, thousands of state and local jurisdictions each set their own rules, rates, and product definitions. A business selling across the country faces a moving maze, and Vertex is one of the main companies that automates the maze.
Here is the core problem it solves. If you sell a chair online into a state, whether you owe tax can depend on whether the chair is taxable there, whether you have enough presence in the state to owe anything at all, and how the local rate stacks up. Get it wrong and you face penalties. Vertex keeps a giant, constantly updated library of these rules and plugs it into a company's billing system, so the right tax gets charged at checkout and the paperwork is ready later. Its biggest customers are large enterprises, and its main rival is Thomson Reuters, another big tax and accounting software provider. Vertex earns money mainly by charging subscription fees for that software, plus fees for services like setup and help with filings, and it has been expanding into the corporate tax side too — not just sales tax but income tax compliance. It reported about $667 million in revenue in 2024, growing roughly 16% over the prior year, and it spends heavily on sales and research to keep its rule library current. Its competitors, including Avalara in the sales tax space, fight over the same enterprise customers, so scale and keeping the rule library accurate and fresh matter enormously.
In 1978, Ray Westphal started Vertex in King of Prussia, Pennsylvania, to help big companies handle a boring but painful job: figuring out and paying their indirect taxes. Sales tax, use tax, VAT, payroll tax — every sale and every employee could trigger a different rule, and getting it wrong meant penalties. Vertex built software and services that automated the whole mess, and that simple idea became the foundation of the business.
In 2000, Ray and Antoinette Westphal sold the company to their three children — Jeff, Stevie and Amanda. The siblings then did something that mattered more than it sounds: they brought in outside directors who had run big public companies before. The family credits that move as the key to growing up from a family business into a real company.
In 2016, David DeStefano — who had joined back in 1999 as finance chief and worked his way up — replaced Jeff Westphal as CEO. For the first time, a professional manager, not a family member, ran the day-to-day business, while the founding family stayed on the board and kept control through special voting shares.
In 2020, Vertex listed its shares on Nasdaq to raise money and grow faster. The timing was strange: the pandemic had shut down travel, so the paperwork, the investor meetings and the whole roadshow happened over video calls. Still, the company went public on the strength of a real business — it had booked $322 million in revenue the year before.
In 2024, Vertex went shopping, buying Pagero in January and ecosio in September. The ecosio deal was the one that stuck in the story: it gave Vertex e-invoicing tools, a way to handle bills and invoices electronically across countries. Vertex would later point to this as a major growth area.
In 2025, David DeStefano retired and the board handed the top job to Christopher Young, a former Microsoft executive and onetime McAfee CEO. The board said it picked him to lead Vertex's next phase of growth, with a big focus on generative AI in tax and compliance. The CEO change would soon become part of a bigger story.
Also in 2025, Vertex put $15 million into Kintsugi AI, a startup using AI to handle sales tax for small and midsize businesses — a market Vertex had mostly served through bigger enterprise clients. At the same time, the company kept folding ecosio's e-invoicing tools into its own products.
Then the story turned. Over the year to early 2026, Vertex shares fell more than 70%, landing around $12.83. Jefferies downgraded the stock and slashed its price target, pointing to weak fourth-quarter numbers and uncertainty about the new CEO. The market, in short, was not convinced the growth story was still on track.
In April 2026, Vertex answered with a plan: cut about 9% of its workforce, trim outside spending, and save $60 million to $70 million a year starting in 2027. That money would go back into e-invoicing, compliance and AI. But the plan came with a reset — management lowered its medium-term revenue growth outlook to low double digits and pushed its old profitability targets out to 2027.
The company has a quirk worth knowing: it has two classes of stock, with founders and early investors holding a special share class that carries more voting power. That structure has been simplified over time, but it means outsiders have less say in how the company is run. Vertex is also closely tied to the odd, fragmented nature of tax rules themselves — every new law, every new state rule, means more work for customers, which creates steady demand for the software, but also means the company must run a big, unglamorous machine of lawyers, accountants, and software people just to stay current.
