Hg-backed Sovos, a global tax software services provider, agreed to acquire TrustWeaver, a provider of cloud-based e-invoicing software. Financial terms were not disclosed. “TrustWeaver has become a seal of approval for the world’s largest financial systems, which is a testament not only to the effectiveness of its software and integrations, but also to its ability to monitor and interpret regulatory change in the European region and beyond. We’ve built Sovos to reduce the costly friction between businesses and governments around the world, and it was immediately obvious to us that TrustWeaver provides an important part of that solution,” Andy Hovancik, Sovos President and CEO.
