Features
Adaptive Financial Solution for Sustainable Growth
KudTax is designed to be scalable adaptable to your business needs, helping you stay organized and focused on growth, without worrying about the complexities of financial data management.
Transaction and Invoice Retrieval
KudTax imports available transaction and invoice data through supported integrations or file imports. Scope and updates depend on the data source, permissions and retrieval status.
AI Copilot
Tell it what you need. Review the card. Apply.
The assistant no longer just answers questions — it does the work: it drafts an invoice, confirms a match, closes the month or connects a portal. Every action arrives as a proposal card you review and apply. Nothing books itself.
Draft an invoice from a sentence
Describe the invoice in plain words — party, net, gross, an existing number to copy — and the assistant fills a booking-ready draft. You check every field and apply it; the AI never books on its own.
