Avalara buys Versori to boost AI-driven integrations

Avalara has acquired integration platform provider Versori, adding automated connector development and agentic AI workflows to its product group.

Financial terms were not disclosed. The deal adds technology and staff intended to increase the number and speed of system integrations across Avalara's compliance products.

Versori develops tools for building and maintaining software connectors between business systems. It positions its approach as automation-first, focused on repeatable connector development.

Integration focus

Integrations are central to tax and compliance software because they connect transaction data in finance, eCommerce and operational systems to calculation, reporting and filing processes. Vendors typically build and maintain large libraries of connectors to enterprise resource planning systems, online shopping platforms, marketplaces and payment tools.

Versori's technology is expected to strengthen Avalara's ability to scale integrations across thousands of systems. Avalara also tied the acquisition to its strategy for real-time compliance processes that remain active across transaction flows.

Versori's products aim to reduce the time needed to deploy new integrations and cut the effort required to keep them up to date. Connector maintenance has grown more complex as software providers release frequent updates and organisations add new channels for sales, billing and fulfilment.

The acquisition includes Versori's platform and employees. Versori's co-founders and other team members will join Avalara and continue work on integration and agentic AI features across its platform.

Versori will operate as a sub-brand, Versori by Avalara, signalling plans to keep the Versori identity in the market while integrating the technology into Avalara's broader product set.

Product strategy

Avalara sells tax calculation and compliance software that connects to customers' transaction systems. It supports more than 200,000 customers directly and indirectly across more than 75 countries, and has built a large library of tax content and integrations over more than two decades.

Avalara has been emphasising automation and AI in product messaging, including the use of AI agents for tax calculation, return filing and exemption certificate management. This acquisition adds automation focused on building connectors and operating those links over time.

Businesses operating across multiple countries often run a mix of ERP suites, eCommerce platforms and financial applications, while also navigating shifting tax rules and reporting requirements. In that environment, tax engines and compliance tools depend on consistent data feeds from upstream systems and need integration coverage across many software stacks.

"Compliance at global scale depends on seamless, reliable integration," said Scott McFarlane, CEO and Co-Founder, Avalara. "Versori's technology and team significantly accelerate our ability to connect into the world's commerce systems quickly, at scale using intelligent, AI-driven automation that meets the reliability and accuracy standards global compliance demands. This acquisition strengthens our unified platform and advances Avalara's vision of AI-native compliance that operates continuously, intelligently, and at scale across the world's most trusted commerce systems," added McFarlane.

Operations and people

Versori's team will continue advancing integration and agentic AI capabilities across the Avalara platform. Keeping the founders involved suggests Avalara is seeking continuity in product direction and retaining specialised technical expertise.

Avalara described Versori's technology as cloud-native. Cloud deployment is now a default expectation for integration platforms, as customers look for simpler rollout across distributed environments and faster update cycles.

In the tax and compliance sector, integration breadth is often a competitive factor. Customers typically adopt these tools alongside large ERP deployments or fast-growing eCommerce operations, where a platform change can cascade into updates for tax and compliance settings.

Avalara framed the deal as part of a longer-term shift toward "always-on" compliance, where compliance checks and tax determinations occur during transaction processing rather than after the fact.

No timeline was provided for product releases tied to the acquisition. Versori's co-founders and other team members are expected to work within Avalara on integration development and AI-related workflows as the combined roadmap takes shape.
