Leadership Comments

“Sales tax has become a much bigger operational challenge as companies grow across markets, systems and business models,” said Sam Ross, co-founder and CEO of Numeral. “Businesses need infrastructure that can keep pace as rules and requirements change across jurisdictions, without adding more manual work for their teams.

“Sales tax is mission-critical to get right, and the complexity is only growing as regulations expand into new products and markets,” said Rebecca Liu-Doyle, Managing Director at Insight Partners. “We tracked this space closely and saw Numeral consistently deliver — customers repeatedly pointed to the company’s reliability, accuracy, and high level of service.

Market and Business Growth

Numeral has expanded across software, distribution, and manufacturing, with growth in customers from these industries.

The company says its platform can reduce the time spent on tax filings and registrations by up to 80% and reduce manual spreadsheet work and filing errors by up to 95%.

Its exemption certificate management service can save companies up to 400 hours annually. Numeral also says that when existing certificates are moved onto its platform, 30% to 40% often fail validation.

The platform supports VAT and GST compliance in more than 90 countries and integrates with over 40 billing systems, financial platforms, and ERP systems.

What Happens Next?

Numeral plans to invest in product development and expand its team as it grows across different industries. It will also continue developing its accounting partner program and supporting businesses and accounting firms with sales tax compliance.
