The story

Sovos evolved from a US-focused sales/use tax and 1099 reporting vendor into a global 'always-on' tax compliance platform through a decade of acquisitions (Taxware, Invoiceware, Trustweaver, Paperless, Acepta, Accordance, Taxweb, FIT). Under Hg/TA ownership since 2020, the company has consolidated its portfolio into the Sovos Compliance Cloud with three suites: Indirect Tax, Information Reporting & Withholding, and Trust & Identity (LATAM digital identity/e-signature from the Acepta/TOC acquisitions). Recent strategy centers on agentic AI (Sovi) and 'Mirror Visibility' — matching what tax authorities already see in real-time e-invoicing regimes.
