How engineering consultancies work

An engineering consultancy sells expertise by project: structural calculations, surveys, feasibility studies and site inspections for architects, developers, contractors and homeowners. Work comes from repeat relationships and tenders, and is billed by fixed fee, stage or hourly rate. Engineers split time between the office and sites, often writing notes on paper or a tablet on site and typing them up again at the desk. Drawings, calculations, report revisions and inspection photos live in shared folders and email chains.

What quote & estimate app for Engineering Consultancies has to handle

  • Scope by stage, with inclusions and exclusions.
  • Site visits priced separately.
  • Assumptions, like drawings supplied by the architect.
  • Validity period and payment terms.

A tip for engineering consultancies

List exclusions clearly, such as additional site visits or redesign after planning changes. Scope creep on engineering projects often comes from work nobody thought to exclude.

A prompt to start from

Build a quote and estimate app for an engineering consultancy. Keep a price list of services such as structural design, surveys, feasibility studies and site inspections with a default rate. Let me create a quote for a customer with client name, project and discipline, 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

Should engineering quotes include assumptions?

Yes, state what information you rely on, like the architect's drawings, so any changes can be quoted as extra work.

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.
