How sustainability consultancies work

A sustainability consultancy's calendar follows its clients' reporting years. Carbon footprints and ESG reports cluster in the months after a financial year closes, while net zero plans and certification support run as longer projects. Most of the hours go into collecting data: utility bills, fuel cards, travel expenses and supplier figures that arrive as PDFs and mismatched spreadsheets. Work comes through referrals, procurement requirements and investor pressure. Software helps most by giving clients one place to submit data and by tracking each engagement against its deadline.

What quote & estimate app for Sustainability Consultancies has to handle

  • Pricing scales with the number of sites, entities and the scope of emissions included.
  • Supplier engagement, target setting or certification support can be offered as optional line items.
  • The quote should state assumptions about data quality, such as a surcharge if records must be estimated from invoices.
  • A timeline in the quote needs to be tied to the client's reporting deadline.

A tip for sustainability consultancies

Scope creep in this work comes from the value chain. Quote value chain emissions as a separate, clearly limited line, stating which categories are included, so the client does not assume a starter footprint covers every supplier and product.

A prompt to start from

Build a quote and estimate app for a sustainability consultancy. Keep a price list of services such as carbon footprinting, ESG reporting, net zero plans and certification support with a default rate. Let me create a quote for a customer with client company, reporting year and scope, add line items with quantity, rate and discount, and see a total with tax. Give each quote a number and a shareable page where the customer can accept or decline it, and show all quotes in a list with status and value. Use a database and add a login for staff.

Questions

How do we price a first carbon footprint?

Most firms price by complexity: number of sites and entities, emission categories in scope, and how clean the data is. A quote builder can apply your rates to those inputs, and you can ask for it in chat.

Can a customer accept a quote online?

Yes. Each quote gets its own page with an accept and decline button, and the status updates in your list. Ask Mythex to email you when a quote is accepted.

Can an accepted quote become an invoice?

Ask for it in chat: Mythex adds a button that copies an accepted quote's line items into an invoice, so clients are billed exactly what they agreed to.

Do I need to know how to code?

No. You describe what you want in plain language and Mythex writes the code, shows a live preview, and lets you change things by chatting. The code editor and terminal are there if you ever want them.

Do I have to explain my business every time?

No. Mythex remembers who you are and how you work across every project, and follows the standing notes you set for a project, so you are not re-briefing it in each new chat. You can read, edit or switch all of it off.

How much does it cost?

There is a Free plan with daily credits, enough to build and publish a first version. Pro is $25/month and adds full code editing, GitHub export, custom domains, and credit top-ups.
