Blue dot

From VATBox to a tax platform

Blue dot was founded in 2012 by Isaac Saft and Noam Guzman, according to UKTN, and previously operated under the name VATBox. Its field is handling the tax that arises from the expenses of organizations and employees. According to the Sovos announcement, the company is headquartered in Tel Aviv. The product takes in information about purchases, travel and payments to suppliers, and prepares it for use by finance and tax teams. The company connects documents and transactions to tax rules, instead of settling for a store of receipts or entering amounts into a spreadsheet.

What is checked on a receipt and an invoice

According to the acquisition announcement, the AI extracts information from invoices, receipts and expense reports, cleans it, verifies details and enriches the context of the transaction. The goal is to identify expenses eligible for VAT refunds and to support reporting that complies with the rules. The company's website describes a calculation based on each country's regulations, rulings, tax decisions and the business's requirements. Alongside VAT recovery there is an application for reviewing employee benefits subject to payroll tax. Another product examines expenses and receipt images to flag errors, suspicious expenses and breaches of travel policy.

Rules alongside models

The Blue dot website describes a combination of AI with rule-based analysis. It is meant to deal with partial information and missing checks in employee expense processes. According to Sovos, the platform also includes an engine that coordinates the system's components and a knowledge graph of transactions. This way an expense document is examined together with the transaction details and its tax context. The website describes the documentation work finance teams need to do ahead of audits by tax authorities, and the product is meant to reduce that manual work. According to Sovos, the platform includes more than 150 purpose-built models. This is a description of processing expense data and matching it to requirements, not just a tool for generating text. Sovos describes processing information that comes from different systems along the purchasing and payment process. The cleaned data is meant to fit into the compliance and review processes of finance teams.

Funding and customers

In April 2021 Blue dot raised $32 million, according to UKTN. The round was led by Ibex Investors, with participation from Lutetia Technology Partners and existing investors including Viola and Target Global. The company's website shows customer testimonials from Zoetis, Vestas, Michelin and Dell about using its products. Sovos describes distribution through SAP Concur and hundreds of enterprise customers in finance, retail, manufacturing and consumer goods. The usage figures and testimonials are information published by the company and the buyer; they are not an independent measurement of the tax recovered in each organization.

The acquisition by Sovos

On 15 September 2026 Sovos announced the acquisition of Blue dot. The announcement presents an expansion of the buyer's tax platform into travel expenses and VAT recovery. It also describes the data science and engineering teams joining the product and technology organization. Integrating the AI into Sovos's transaction review process is presented as a plan for the future, including explaining the source of an error and not just flagging it. The deal amount is not given in the announcement. The Blue dot website continues to present the products under its own brand.
