Construction Company Software You Build by Describing It

With Mythex a builder can describe the tools the office keeps patching together and get them as working apps: a website with real project galleries, a client portal for progress photos and variations, a quote builder that lists exclusions, and a dashboard of budget against actual cost per site. Each one has its own database and goes live at a public URL.

What a building firm actually needs from software

A construction company is several jobs running at once, each at a different phase. Groundworks on one site, first fix on another, snagging on a third. The money comes in stage payments, minus retention, plus variations that somebody agreed on site. The trouble is that the facts live in different places: progress in a site manager's WhatsApp photos, valuations in an office spreadsheet, subcontractor insurance in an email from last year. Clients ring to ask when the kitchen goes in because they cannot see anything. Good software for a builder puts each project's phase, cost, photos and paperwork in one record that both the office and the client can trust.

One record per project with site address, phase, contract value and planned versus actual dates
Variations priced and approved in writing before the work starts
Stage payment invoices raised the day a phase is signed off, with retention tracked
Subcontractors listed by trade with rates and insurance expiry dates
Tools and plant logged to a site or a person so they stop going missing

What you can build for construction companies

A website that proves you have built this before

Homeowners and developers hire on evidence. The site Mythex builds leads with case studies: before, during and after photos, the challenge, the timeline and the project type. Accreditations, insurance and trade memberships sit where people look for them, and the inquiry form asks for budget, start date and postcode so jobs outside your area or range are filtered before you ring back.

Build a website for our building firm. We do extensions, loft conversions, refurbishments and new builds within 30 miles of Leeds. Add a projects gallery with before, during and after photos for each job, an accreditations section, and an inquiry form that asks for budget range, planned start date, postcode and whether planning permission is granted.

A client portal that replaces the progress phone calls

Each client logs in to their own job and sees photos posted by phase, the drawings and certificates, the stage payment schedule and every variation with its price. Variations are approved by the client inside the portal before the trade starts, which is the single best way to avoid an argument at final account.

Build a client portal for a construction company. Each client sees only their own project: phase timeline, progress photos per phase, drawings and building control certificates, stage payment schedule and invoices. Add variations with a description and price that the client approves or rejects in the portal, with the date recorded.

Quotes that show what is excluded

Clients compare tenders on the bottom line, so a careful quote can lose to one that hides the extras. A quote builder groups line items by phase or trade, keeps provisional sums and exclusions on the page, carries a validity date because material prices move, and saves each revision as a new version.

Build a quote builder for a builder. Line items grouped by phase (groundworks, superstructure, roof, first fix, second fix, finishes), provisional sums, a clear exclusions list, VAT, a 30-day validity date and version numbers when a quote is revised. Export a PDF and track whether each quote is sent, won or lost.

A weekly view of cost against budget on every site

An overrun noticed at frame stage can still be managed. Found at handover, it has already eaten the margin. A dashboard shows each live project's phase, planned against actual dates, budget against cost to date, pipeline value from open quotes and the money owed in stage payments and retention.

Build a dashboard for our construction projects. For each live job show phase, planned and actual completion dates, budget, cost to date and percentage overrun. Add totals for quote pipeline value, win rate, unpaid stage payments and retention still held. Let me import costs from a CSV each week.

A tool and plant log that follows kit between sites

Drills, breakers, mixers and lasers walk between sites. A simple check-out record ties each item to a site or person, holds service and inspection dates, and lets the yard see what came back. Materials delivered to site can be checked against what was ordered.

Build an inventory app for a construction company's tools and plant. Each item has a tag number, category, current site or person, purchase cost and next service or inspection date. Check items out and in from a phone, show overdue inspections, and log material deliveries to each site against the purchase order.

Survey bookings grouped by area

Quotes win the work, and surveys produce the quotes. A booking page lets prospects pick a site survey slot, a showroom consultation or a snagging inspection, and the admin view groups survey visits by area so an estimator can do four in one part of town instead of crossing the county twice.

Build a booking page for site surveys, design consultations and end-of-job snagging inspections. Surveys take 90 minutes plus travel time, and the admin view should group the day's surveys by postcode area. Save the client name, site address, project type and planning status.

From WhatsApp photos to a project record

Most builders already have the information; it is just scattered. Start by listing every live job in one table: client, site address, phase, contract value, next stage payment. Then ask Mythex to add a photo upload per phase so site managers post progress from their phone instead of a group chat. Once that works, add the client view on top of the same data. You are not replacing how the site runs, only where the record lives.

Week one: live jobs table with phase and value
Week two: progress photos per phase from a phone
Week three: client logins and variation approvals

Retention, variations and stage payments

Ask for these explicitly in your prompt, because they are what generic invoicing tools get wrong for builders. A stage payment invoice should reference the milestone and carry the photos that show it was reached. Retention should be held as a percentage and released after the defects period with a reminder date. Variations should be invoiced on their own lines, each with the approval reference from the portal.

Questions

Can clients see their build progress online?

Yes. Ask for a client portal and each client logs in to see only their own project: photos by phase, documents, payments and variations. Site staff upload photos from a phone and they appear straight away.

Can it handle stage payments and retention?

Describe your payment structure in the prompt, such as 10% deposit, stages at frame and first fix, and 5% retention for six months. Mythex builds the invoices and the tracking to match, including a reminder when retention is due for release.

Do I need to know how to code?

No. You describe what you want in plain words and Mythex builds it with a live preview. You change it the same way, by chatting, and the code editor is there if a developer ever wants to look.

Is it free to build a construction website?

The Free plan needs no credit card and gives daily credits, which is enough to build and publish a first version. Pro costs $25 a month and adds a custom domain, code editing, export and more credits.

Can my site managers use it on their phones?

The apps work in a phone browser, so photo uploads and tool check-outs work on site. On Pro you can also turn a published app into Android and iPhone apps that open your published app.
