Rateslip’s home page: the headline “The rate went up. The freight came down. Nothing actually changed.” beside a synthetic purchase order with Version B selected, its rate and transport figures highlighted, and under it the landed cost per square metre read from both versions, ₹1,297.25 each, with the verdict “Comparable · landed cost identical”

Rateslip

Reads supplier quotations, purchase orders and invoices, and puts every line on one landed cost per unit.

Reads the printed page, not the file’s hidden text · a missing cost stays unpriced

Redact PDF

Redaction that takes the text out of the file, not a box over it. The file never leaves your device.

Services

Four things we build. Fixed scope, fixed price.

Every engagement begins with a written scope, a fixed price and a date. Scoping is free on websites and web applications; AI systems begin with a paid scoping phase.

Websites

Quoted in a written scope

Brand and marketing sites for e-commerce and B2B, built to load fast and convert.

  • Static pages, with no server to patch and no monthly fee
  • A performance budget the site has to meet before launch
  • Content in your repository; a CMS only if you ask for one

About websites

Web Applications

Quoted after a scoping call

Portals, dashboards, calculators and internal tools that replace spreadsheets.

  • In the browser where it can be; a database you own where it cannot
  • Sign-in, roles and an audit trail where the application needs them
  • Weekly staging builds you can click through

About web applications

AI Systems

A paid scoping phase, then a quote

Agentic applications, MCP and API integrations, and workflows, built with the controls to run them in production.

  • Agents, MCP integrations and multi-step workflows
  • Scoped permissions, and approval before any change
  • Evaluated and logged, with gaps reported, not filled

Rateslip · every figure kept with the part of the page it was read from

About AI systems

Design

Priced as part of the build

Interface design and design systems, done as part of a build. Not sold on its own.

  • Token sheet and component library first
  • Every screen at 390 and 1440
  • Handed over as code, not as a file

About web applicationsKordal Labs
Process

Four stages. Clear from the start.

A written scope, a fixed price and a date before anything starts. The weeks below are a typical website build; an application or an AI system is scheduled in its scope.

  1. Scope

    One call, then a written scope with a fixed price and a date. Signed before any work starts.

    Week 1

  2. Design

    Tokens and components first, then every screen at mobile and desktop. Two rounds of revision included.

    Weeks 1–2

  3. Build

    A staging link every Friday. You click through real pages, not slides.

    Weeks 2–5

  4. Launch

    Your domain, your accounts, a written handover. Thirty days of fixes included.

    Weeks 4–6, then 30 days of support

How we work
From a client

A client, in his own words.

“We'd just registered the LLC and honestly didn't know what our website needed to be. I sent one paragraph about the brand. What came back was a compliance page, a fit tool, a journal and a video header — none of which I asked for, and all of which I now understand why we needed. During our Mercury verification call, the person checking our account stopped to ask who had built it.”
