The five-phase automation method
From business friction to a working system.
A serious automation project needs more than a clever demo. It needs a clear problem, sensible architecture, reliable implementation, realistic testing and a clean launch.

Questions
Before we work together.
A few practical answers about the automation work, companies and author platform represented here.
What kind of AI automation projects do you take on?
Projects can include lead handling, follow-up, document workflows, AI-assisted operations, integrations, reporting, internal tools and conversion-focused web systems. The final scope is based on the business bottleneck and available systems.
How does the five-phase method work?
The project moves through discovery, workflow design, build and integration, validation, and launch. This keeps the work understandable, reviewable and easier to improve.
What is the relationship between this site and Technosmith?
This is the personal portfolio and author website of Santonu Kumar Dhar. It presents his founder role across Technosmith Limited in the UK, Technosmith, Inc. in the USA, and the Prachesta product.
Is Prachesta already HMRC recognised for MTD?
Prachesta is still in development, and HMRC Making Tax Digital approval is not yet granted. Product pages should continue to present this status clearly until approval is confirmed.
Can I contact you about books as well as technology?
Yes. This website intentionally brings together both sides of the work: business technology and the books, essays and ideas created as an author.
