Why Kehai

Built by someone who has done the work.

I spent my career doing the VAT work this product now drafts. I built Kehai to turn relentless cross-border VAT/GST change into clear, business-specific, source-backed action.

Indirect tax at global scale

VAT, GST, US sales & use tax and customs across 45+ jurisdictions; M&A and post-merger integration; audit defence; operating-model design; recoverability and operational visibility.

Tax technology

ERP and tax-engine programmes, e-invoicing and digital reporting (France, Italy SDI, MTD, SAF-T, DAC7, CESOP, ViDA), governance aligned to SOX.

And I build

Production AI tooling and web apps that take the manual load off compliance. Kehai runs on that same stack.

The experience behind Kehai

The problem I kept living

I've led indirect tax across 45+ jurisdictions in EMEA, the Americas and APAC (VAT, GST, US sales tax and customs), through ERP transformations, multiple post-merger integrations, and the daily reality of keeping a 200-plus-return footprint under control. The hard part was never finding the change. It was the work after: whether it actually affects the business, why, who owns the response, by when, and proving the source behind every position. That judgement layer lived in inboxes, spreadsheets and people's heads.

Built on one principle

Every claim shows its source, and the distinct trust signals (official source, claim support, reachability, human review) are never collapsed into a single tick.

A reviewer should be able to see what the system knows, what it has inferred and what still needs their judgement.

Kehai turns changes from configured sources into a shared review process. Your team can assess the impact, assign the response and keep the evidence together, alongside the systems you already use.

How it runs in practice

Your reviewers make the decision

Kehai drafts assessments. Your named reviewers approve, reject or turn them into owned actions. Sign-off is recorded in the audit trail; your tax judgement stays with your team.

The evidence stays usable

Each item can be exported as a self-contained evidence pack. Your workspace data is stored in the European Union, with AI processing in the United States as explained on the Security page.
