AI Quote and Estimate App Builder for Construction Companies
Stop rebuilding the same estimate in a spreadsheet. Describe how your construction company prices new builds and extensions 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
Owners and estimators at construction companies who want every quote numbered, saved and easy to find when the client calls back.
What you can build
- A price list of new builds, extensions and refurbishments 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 construction companies work
A construction company runs several sites at once, each moving through phases like groundworks, frame, first fix, second fix and snagging. Work is won through tenders and quotes, paid in stage payments, and depends on subcontractors, material deliveries and the weather. Site managers send progress by WhatsApp photos, the office tracks valuations in spreadsheets, and clients want to know when their extension will be done. Spring and summer are busiest, and delays cascade quickly.
What quote & estimate app for Construction Companies has to handle
- Line items grouped by phase or trade.
- Provisional sums and exclusions spelled out.
- A validity date, since material prices change.
- Quotes that can be revised and versioned.
A tip for construction companies
List exclusions and provisional sums clearly in every quote. Clients compare quotes on the total, and a lower price from a competitor often hides items that will come back as extras later.
A prompt to start from
Build a quote and estimate app for a construction company. Keep a price list of services such as new builds, extensions, refurbishments and project management with a default rate. Let me create a quote for a customer with client name, site address and phase, 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 long should a building quote be valid?
Many builders set a fixed validity period because material and labor costs move. Put the date on the quote and requote if the client accepts after it expires.
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.
