Best Quoting App for Builders (2026)

The best quoting app for builders in 2026 is one that handles multi-phase projects, calculates materials at scale, and manages VAT and CIS deductions without forcing you to become an accountant. After testing the main options on real building jobs, here is how the five leading apps compare.

Builders have the most complex quoting requirements of any trade. A plumber quotes a boiler swap. A painter quotes a room. A builder quotes a kitchen extension with structural work, first fix, second fix, decoration, landscaping, and six weeks of coordinated subcontractors — all while tracking material costs that change weekly and managing CIS returns for every sub on site.

Most quoting apps were designed for simpler workflows. They work well enough for single-trade jobs, but they creak under the weight of a real building project. This guide compares the five apps that builders actually use, explains what makes each one strong or weak, and recommends the best option for your specific situation — whether you are a sole trader doing extensions or a multi-trade contractor running new builds.

What to Look for in a Builder Quoting App

Before comparing individual apps, it helps to know what matters most for building work. Not every feature on a quoting app's marketing page is relevant to you. These are the ones that are.

Multi-phase project support

A kitchen extension is not one job. It is groundworks, structural steelwork, brickwork, roofing, first fix electrics, first fix plumbing, plastering, second fix, kitchen fitting, decoration, and snagging. Your quoting app needs to break a project into phases with separate costs, timelines, and margin calculations for each phase. If the app only supports flat line-item lists, you will end up with quotes that run to five pages and confuse the customer.

Material estimation at scale

Quoting materials for a loft conversion is different from quoting materials for a tap replacement. You are dealing with structural timber quantities, insulation coverage calculations, plasterboard sheet counts, and hundreds of individual fixings. The app should let you estimate materials from dimensions — ideally from photos or descriptions — rather than forcing you to manually add every item.

Subcontractor and labour coordination

Most builders bring in specialists: electricians, plumbers, gas engineers, roofers. Your quoting app should handle subcontractor costs as a distinct category, with markup, and ideally help you manage CIS deductions for those subs.

VAT and CIS handling

If you are VAT-registered (and most established builders are), your app must handle VAT correctly across mixed-rate items. New-build residential work is zero-rated. Renovation work is standard-rated. Some energy-saving materials are reduced-rate. Getting this wrong costs real money. CIS deductions for subcontractors add another layer — the app should calculate the 20% (or 30%) deduction and help you produce CIS vouchers.

Professional presentation

Builders quote on bigger-ticket jobs than most trades. A loft conversion runs £40,000-£70,000. A new build can be £200,000 or more. At those prices, customers expect a professional document — not a text message with a number. Your quoting app should produce clean, branded PDFs that break down costs clearly without revealing your margins.

Speed

Despite all that complexity, you still need to quote quickly. The builder who sends a detailed, professional quote within 24 hours wins the job over the one who takes two weeks. The app should help you produce complex quotes faster, not just make them look prettier.

The 5 Best Quoting Apps for Builders Compared

1. Sleepless Tradesman

Best for: Builders who want AI to handle the heavy lifting on complex quotes

Sleepless Tradesman takes a fundamentally different approach. Instead of filling in forms and line-item lists, you describe the job in a conversation — by text or voice — and the AI builds the quote for you. You can also upload site photos and the AI analyses conditions, dimensions, and scope to generate a starting estimate.

For builders, this matters because of the sheer complexity involved. Describing a ground-up new build to the AI is faster than manually entering 200 line items across 12 project phases. The AI understands construction terminology, knows typical material quantities per square metre, and structures the quote into logical phases automatically.

Key features for builders:

• Conversational quoting — describe a kitchen extension naturally and get a structured, multi-phase quote back
• Photo analysis — upload site photos and the AI assesses conditions, identifies scope, and estimates quantities
• Remote quoting — customers can submit job details and photos through a link, so you can price without a site visit
• Multi-phase project breakdown with separate costings per phase
• AI material estimation based on dimensions and job descriptions
• Professional branded PDF output
• UK-focused with VAT handling

Pricing: Free plan available. Pro plan at £59.99/month for unlimited quotes and full AI features.

Demo: You can try the builder-specific demo at sleeplesstradesmen.com/try/uk/builder/london↗

Strengths: The AI approach genuinely saves time on complex quotes. A loft conversion quote that would take 45 minutes to build manually can be generated in under 10 minutes through conversation. The remote quoting feature is particularly useful for builders — customers send photos and descriptions, you review and refine the AI-generated quote, and send it back without leaving site. Photo analysis is not perfect, but it gives a solid starting point that you adjust based on experience.

Weaknesses: Newer to market than some competitors. The AI occasionally needs correcting on specialist material specifications — it might suggest a generic structural steel price when you know the exact beam spec and cost. You review and adjust, which is the right workflow, but it means the AI is a starting point rather than a finished product.

2. Powered Now

Best for: Builders who need paperwork, certificates, and compliance documentation alongside quotes

Powered Now is built in the UK for UK tradesmen. It started as a paperwork and forms tool — gas safety certificates, electrical certificates, risk assessments — and expanded into quoting and invoicing. For builders who deal with a mountain of compliance paperwork, that heritage is valuable.

Key features for builders:

• Quote and invoice creation with customisable templates
• Digital forms and certificates (RAMS, method statements)
• Customer signature capture
• CIS and VAT support
• Offline mode for sites with poor signal
• Job scheduling and tracking

Pricing: From approximately £20/month.

Strengths: The compliance and paperwork side is genuinely excellent. If your building work requires risk assessments, method statements, and various certificates, having everything in one app saves time. UK-built means VAT and CIS are handled natively, not bolted on. Offline mode is a real advantage on remote building sites.

Weaknesses: The quoting tool itself is fairly traditional — manual line items, no AI assistance, no photo estimation. For complex multi-phase projects, you are still building quotes by hand. The interface can feel dated compared to newer apps. No conversational or AI-powered quoting means complex jobs still take significant time to price.

3. Tradify

Best for: Small building firms that need job management and scheduling alongside quoting

Tradify positions itself as a job management platform rather than just a quoting tool. For builders running multiple jobs simultaneously — which is most builders — the scheduling, job tracking, and team management features are as important as the quoting.

Key features for builders:

• Quote creation with templates and saved items
• Job scheduling with calendar view
• Team management and job assignment
• Time tracking per job
• Purchase order management
• Invoicing and payment tracking
• Xero and QuickBooks integration

Pricing: From approximately £29/month per user.

Strengths: The job management workflow is well-designed. You create a quote, it converts to a job, you schedule the job, track time and costs against it, and invoice from the same record. For builders juggling multiple projects, seeing everything on a calendar with assigned team members is genuinely useful. The Xero integration works smoothly for accounting.

Weaknesses: Quoting itself is basic — manual line items without AI assistance or photo estimation. Per-user pricing gets expensive if you have a team: five users at £29 each is £145/month. Originally designed for the New Zealand and Australian markets, so some UK-specific features (CIS, UK VAT edge cases) are less mature than UK-native apps. No multi-phase project structure — you work with flat quote templates.

4. Xero

Best for: Builders who want accounting-first software with basic quoting built in

Xero is an accounting platform, not a quoting app. But many builders already use Xero for their bookkeeping, and its built-in quoting feature is functional enough for simple jobs. If you are already paying for Xero and your quotes are straightforward, it avoids adding another subscription.

Key features for builders:

• Quote creation with line items
• Direct conversion from quote to invoice
• Full double-entry accounting
• VAT returns (Making Tax Digital compliant)
• Bank reconciliation
• CIS module (available on higher plans)
• Extensive app marketplace for add-ons

Pricing: From £15/month (Starter plan). The plan with full invoicing and CIS support starts at £30/month. CIS module may require an additional add-on.

Strengths: If accounting is your priority, Xero is hard to beat. VAT returns, Making Tax Digital compliance, bank reconciliation, and CIS management are all built-in or available as add-ons. Quote-to-invoice conversion is seamless because everything lives in the same accounting system. The app marketplace means you can bolt on specialist tools for scheduling, project management, or time tracking.

Weaknesses: Quoting is a secondary feature, and it shows. No templates designed for construction work. No photo estimation, no AI, no voice-to-quote. Multi-phase projects are not natively supported — you would create separate quotes for each phase, losing the overview. The interface is designed for accountants, not tradesmen. No job scheduling, no site-specific features, no offline mode. You are using an accounting tool to do a quoting job.

5. Jobber

Best for: Larger building firms focused on scheduling, dispatch, and client communication

Jobber is a field service management platform from North America that has gained traction in the UK. It is strong on scheduling, dispatch, and client communication — useful for building firms with multiple crews working across different sites.

Key features for builders:

• Quote creation and follow-up automation
• Job scheduling with drag-and-drop calendar
• GPS tracking and dispatch
• Client hub for customer self-service
• Automated quote follow-ups and reminders
• Online payment collection
• Reporting and job costing

Pricing: From $49/month (approximately £39/month). The plan with quoting features starts at $129/month (approximately £103/month).

Strengths: Client communication is excellent. Automated quote follow-ups, appointment reminders, and a client portal where customers can approve quotes and pay invoices online. For builders who lose jobs because they forget to follow up, the automation alone could pay for the subscription. GPS tracking and dispatch is useful for firms with multiple crews. Reporting gives you visibility on profit margins per job type.

Weaknesses: North American origins mean UK-specific features are weaker. CIS is not natively supported. VAT handling is present but less nuanced than UK-built alternatives. Pricing is in dollars and aimed at the US market — the features you need for building work (quoting, multiple users) push you to higher tiers that get expensive. No AI-powered quoting or photo estimation. The quoting tool itself is manual and template-based.

Comparison Table

Best App by Scenario

Different builders have different needs. Here is a recommendation based on your situation.

Sole trader builder doing extensions and renovations

Best choice: Sleepless Tradesman

As a sole trader, your biggest constraint is time. You are on site all day and quoting in the evenings. You cannot afford to spend an hour building a quote for a kitchen extension when you have three other enquiries waiting.

The AI-powered approach lets you describe the job — even from the van on the way home — and get a multi-phase quote generated in minutes. Upload the customer's photos, let the AI assess the scope, review and adjust based on your experience, and send a professional PDF. The free plan lets you test it without commitment, and the Pro plan pays for itself if it wins you one extra job per month.

Typical scenario: A homeowner sends you photos of their kitchen and asks about a rear extension. You upload the photos, tell the AI it is a 4m x 3m single-storey rear extension with bi-fold doors, and get a phased quote covering groundworks, structural, brickwork, roofing, internals, and finishing. You adjust the numbers to match your rates and local material costs, and send a branded PDF — all before the other three builders have even called the customer back.

Small building firm (2-5 employees)

Best choice: Tradify or Sleepless Tradesman (depending on priority)

If scheduling your team across multiple jobs is the main pain point, Tradify gives you the calendar, job assignment, and time tracking features that a sole trader does not need but a small firm cannot live without. The Xero integration keeps your accountant happy.

If quoting speed and winning more work is the priority, Sleepless Tradesman's AI approach scales well — your estimator (or you) can produce more quotes per day, increasing your hit rate. Pair it with a separate scheduling tool or spreadsheet for job management.

Typical scenario with Tradify: You have two crews on site and a third starting next week. You open Tradify, see the calendar, assign your bricklayer to the extension in Croydon and your carpenter to the loft conversion in Bromley. A new enquiry comes in for a garage conversion — you build the quote from a template, schedule a site visit, and the customer gets an automated reminder the day before.

Typical scenario with Sleepless Tradesman: Your estimator has seven quote requests from the weekend. Instead of spending Monday in the office manually pricing each one, he describes each job to the AI, reviews the generated quotes over a coffee, and sends all seven before 10am. Three customers respond by lunchtime because he was first to quote.

Multi-trade contractor running new builds or large renovations

Best choice: Sleepless Tradesman for quoting + Xero for accounting + a project management tool

At this scale, no single app does everything. You need specialist tools working together. Sleepless Tradesman handles the complex, multi-phase quoting that new builds demand. Xero handles the accounting, VAT returns, CIS deductions, and Making Tax Digital compliance. A project management tool (separate from your quoting app) handles Gantt charts, subcontractor coordination, and build programmes.

Why not an all-in-one? Because new builds involve quoting phases worth £200,000 or more, managing 10-15 subcontractors with CIS, filing quarterly VAT returns, and tracking costs against a build programme over 6-12 months. No quoting app handles all of that well. Use the best tool for each job.

Typical scenario: A client wants a price for a four-bedroom detached house. You upload the architect's drawings and site photos to Sleepless Tradesman, describe the spec in conversation, and the AI generates a phased quote covering foundations, superstructure, roof, first fix, second fix, externals, and finishing. You review each phase, adjust subcontractor rates based on actual quotes from your regulars, add your margins, and produce a professional document breaking down the build into staged payments. The quote goes to Xero as an invoice schedule once the customer signs the contract.

Builder who needs compliance paperwork

Best choice: Powered Now

If your building work involves frequent risk assessments, method statements, RAMS documents, or other compliance paperwork — and if producing those documents is a significant part of your admin burden — Powered Now is the strongest option. The forms and certificates library is unmatched, and having everything in one app (quote, forms, certificates, invoice) simplifies your workflow.

This is particularly relevant for builders working on commercial projects or as subcontractors to main contractors who require full RAMS packs before you step on site.

How to Try It Free

Most of these apps offer free trials, so you can test them on a real job before committing.

• Sleepless Tradesman — Free plan with core features. Try the builder demo at sleeplesstradesmen.com/try/uk/builder/london↗. Describe a real job and see what the AI produces.
• Powered Now — 14-day free trial from their website.
• Tradify — 14-day free trial.
• Xero — 30-day free trial, then discounted rates for the first three months.
• Jobber — 14-day free trial.

The best test is a real one. Take a job you quoted recently — a kitchen extension, a loft conversion, whatever is typical for your workload — and try quoting it in each app. Time yourself. Compare the output. The app that gets you to a professional, accurate quote fastest is the one that will make you money.

Final Verdict

For most builders in 2026, Sleepless Tradesman offers the biggest time saving on the quoting process itself — which is the part that directly wins or loses you work. The AI handles the complexity that makes builder quotes so time-consuming, and the remote quoting feature means fewer wasted site visits.

If you need job scheduling and team management alongside quoting, Tradify is the strongest all-in-one option, though quoting is manual.

If compliance paperwork is your main admin burden, Powered Now is purpose-built for it.

And if you are already deep in the Xero ecosystem, its built-in quoting handles simple jobs without adding another subscription — but expect to outgrow it as your projects get more complex.

The right answer depends on where you lose the most time. For most builders, that is the quoting itself — and that is where AI-powered tools are changing the game.
