AI Quote and Estimate App Builder for Architecture Firms

Stop rebuilding the same estimate in a spreadsheet. Describe how your architecture firm prices concept design and planning applications and Mythex builds a quote app: line items, your rates, a total with tax, and a link the customer can accept.

Who it's for

Architecture firms that price every job individually and lose time retyping the same line items into a document for each enquiry.

What you can build

  • A price list of concept design, planning applications and technical drawings you can add to any quote
  • Line items with quantities, your rates, discounts and tax
  • A shareable quote page the customer can accept or decline
  • A list of every quote with its status: draft, sent, accepted, expired
  • Turning an accepted quote into a job or an invoice

How architecture firms work

An architecture firm moves each project through defined work stages: brief, concept, planning or permit submission, technical design, then construction. Fees are usually staged to match. Projects last months or years, so the firm carries many at once, each waiting on a client decision, a planning authority or a consultant's input. Drawings live in CAD and BIM tools, but revisions, approvals and fee tracking often run through email and spreadsheets. Software helps most with a single record of each project's stage, latest drawings and outstanding decisions.

What quote & estimate app for Architecture Firms has to handle

  • Fee proposals broken down by work stage, with some stages optional.
  • Scope written out clearly, including the number of design options and meetings included.
  • Exclusions such as surveys, structural engineering and planning fees listed separately.
  • Acceptance recorded online so it can form part of the appointment.

A tip for architecture firms

Spell out how many design iterations each stage includes. Unlimited revisions are the biggest source of unpaid work in residential architecture, and a number on the proposal makes it easy to charge for the fourth version.

A prompt to start from

Build a quote and estimate app for an architecture firm. Keep a price list of services such as concept design, planning applications, technical drawings and site supervision with a default rate. Let me create a quote for a customer with client name, project and stage, 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

Can a fee proposal have optional stages?

Yes. Ask for optional line items the client can include or remove before accepting, such as construction-stage site visits.

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.
