Jafy

Jafy is invoicing and estimate management software for construction tradespeople and automotive repair facilities. The platform streamlines estimates, invoices, work progress documentation, and repair orders through an AI agent that creates, modifies, and reformulates documents via voice or keyboard input. The AI reads specifications and client requests to prepare compliant estimates and invoices while enforcing regulations by locking finalized invoices and directing users to credit notes for changes. In construction mode, Jafy calculates advance payments, generates progress invoices, deducts prior amounts, and tracks warranty retention. The automotive repair mode includes vehicle fleet management, pre-filling repair orders with stored vehicle data. Integration with B2Brouter automates Factur-X supplier invoice reception, while scanned receipts and invoices are processed for tax data. Accountants can export journals and documentation with one click. Data is stored on French servers.

Klorra AI

Klorra AI is an AI estimating service for custom home builders. Upload an architectural plan PDF; typically in about 4 hours you get back a complete bid you can put in front of a client. Five documents, each viewable in the app and downloadable as Excel or Word: - Quantity takeoff: 400+ measured quantities organized by trade, each cited to its plan sheet. - Cost estimate: line items across 160+ cost codes, calibrated by region. - Scope of work: organized by trade in build order, tied to the estimate line items so the two don't drift. - Conflict report: cross-discipline clashes, code issues, and items that need an architect or engineer to clarify. - Verification notes: what a second-agent QC pass flagged for you to confirm before the bid goes out. How it works: a 7-phase pipeline (Plan Intelligence, Conflict & Issue Review, Building Data Takeoff, Cost Detail Generation, QC Review, Scope of Work Generation, Delivery), every phase on the current Claude Opus model. Fully AI from intake through delivery. The QC phase is an audit whose findings ship to you as the verification notes; it is not a guarantee. Who built it: an active Naples, FL custom home builder that needed it for its own bids. The same pipeline runs our own bids today. We opened it to other builders in 2026. What we're honest about: AI still gets things wrong on custom roof geometry, missing structural pages, hand-marked plan edits, and MEP conflicts that don't show on any single sheet. Klorra flags those so estimators know where to focus their effors. The accuracy disclaimer is in plain English in our terms, and you verify every quantity against your own takeoff before commercial use. Pricing: $299 per bid pay-as-you-go, first bid free with no card. Builder $2,990/yr (14 bids), Pro $8,990/yr (66), Studio $24,990/yr (200); monthly plans available. Annual saves 25%. Serving custom home builders in Florida, North Carolina, South Carolina, and Texas at launch. A complete sample bid is public at klorra.ai/samples, no signup.

Knack for Trades

Knack for Trades is quoting and job software built in New Zealand for electricians and security installers. On site, talk the job as you walk it. Knack drafts your voice notes into scope lines you review, edit and price. AI writes the first draft; you make every call. Upload the plan (or sketch one in the browser), mark it up, and the takeoff counts points and measures runs for you. Parts and labour build up from your own price book and recipes, with your cost, markup and gross profit on screen while the customer only ever sees a clean total. Send one link. Your customer sees a branded quote with selectable options, pins change requests on the drawing, and accepts online against a signed declaration, so what was agreed is a record, not a text message. After the yes, the job is on the schedule: book visits, assign the crew, take job sheets and forms onto site, and sign off before you leave the driveway. Electricians issue CoC and ESC certificates from the job's own data. Supplier invoices file against the job that earned them, and the invoice itself is raised in your Xero (New Zealand), never in Knack. Works in the browser and as iPhone and Android apps. Every plan has the full quoting workflow; scheduling, job forms and certificates are on Pro and Crew. 30-day free trial of every feature, no card.

Konstrap

KontraktorOS

KontraktorOS is a cloud ERP for small and mid-sized construction contractors in Indonesia. It connects the cost estimate (RAB/BOQ) to everything that happens after the tender is won, so estimators, project managers, purchasing, warehouse and finance teams work from the same numbers. Build estimates from analysis templates and a price database or import an existing Excel estimate, then print the quotation. Schedule each estimate item on a Gantt chart with an automatic S-curve. Derive material, equipment and subcontract needs from the estimate, issue purchase orders with tiered approval, record deliveries per delivery note with automatic stock updates, and pay supplier invoices from bank accounts. Track owner contracts with down payment, retention and progress billing, plus cash flow and profit per project. Higher plans add subcontractor and foreman management, rebar and concrete quantities (SNI 2847:2019), payroll, and accounting with automatic journals. Role-based access per module. Free 14-day trial.

Metrea

Metrea is quantity takeoff and construction cost estimating software built for French construction cost consultants (économistes de la construction), quantity surveyors, engineering firms and project managers who price building works from the drawings they receive. Most takeoff tools ask you to trace every room and every wall by hand. Metrea starts from the plan itself. Upload a vector PDF, a scanned or photographed drawing, a Word document with the plan pasted in, a DWG or DXF file, or an IFC model from Autodesk® Revit® or ArchiCAD. Metrea detects the levels and the rooms, reads the room names and the areas the architect wrote on the drawing, and proposes the missing areas, perimeters and ceiling heights from the room outlines. You review each room and validate it in a click. Every quantity keeps its origin: written on the plan, measured on a validated outline, typed in by you, or estimated and still to be checked. Nothing reaches the estimate until it is validated, so every figure can be justified to a client, a contractor or a project owner. From the validated takeoff, Metrea measures floors, walls net of doors and windows, ceilings, skirting, wall tiling, facades and partitions, room by room and level by level. It then builds a cost estimate by trade package, in three finish levels and fourteen French regions, and produces the documents of a French tender: the DPGF bill of quantities, the CCTP technical specifications, a colour-coded markup plan and an Excel takeoff whose totals are live formulas. When contractors send back their priced bills, Metrea compares the bids line by line on the same scope. Projects change, and so do drawings. When the architect issues a new revision, Metrea compares it with the previous one and shows the impact on the estimate, with your adjustments carried over. For BIM workflows, the Metrea plugin for Autodesk® Revit® sends the model to Metrea in one click, with its levels, rooms and the areas calculated by Revit. Work as a firm. Colleagues join your workspace by invitation or with the firm's e-mail domain, with four roles: owner, project manager, quantity surveyor and read-only. Several people can work on the same project at the same time: the room being edited is reserved for whoever is on it, and every change is logged with its author. A version is frozen at each export, and the project can be rolled back to any earlier version. Each room goes through a validation workflow, surveyed, verified then validated, according to each person's role. Pro includes two seats and Cabinet five; a seat is added whenever a colleague joins and removed when they leave. Metrea runs in the browser, with a French interface and nothing to install. Plans start at €149 per month on annual billing. Your first project is free, up to three plan pages, with no credit card required.

Miranda AI

Miranda AI is an artificial intelligence platform for construction companies that automates the documentation work behind bidding, planning and project execution. In the bidding phase, Miranda AI reviews tender documents, drawings and annexes, extracts requirements and risks, delivers a go/no-go feasibility report, drafts the technical proposal section by section using the company’s own templates and prepares the bid budget from quantities in the specifications and drawings combined with the company’s pricing data. In the planning phase, it builds the work schedule based on the company’s productivity rates and criteria. During execution, it tracks progress against the schedule, flags risks, produces site reports and meeting minutes with company templates and answers project questions in natural language. Miranda AI adapts to each country’s regulations and each company’s workflow, and is compatible with Primavera P6, Microsoft Project and SharePoint. Client data remains the property of the client and is not used to train AI models.

NexVolt

NexVolt is quoting software for low-voltage contractors, streamlining estimates for network cabling, camera installation, access control, audiovisual wiring, and fiber optics. Contractors input rates, markups, and service costs once, and the software automates calculations to generate quotes in under five minutes. It supports nine service categories and adjusts for conditions like concrete ceilings or after-hours work with customizable premiums. AI drafts editable project summaries, and quotes are sent as browser-based documents for e-signatures. A customer request portal, shareable via links or QR codes, auto-populates service details into the contractor's inbox. Integrated invoicing supports online payments, while a portfolio feature organizes completed projects. The system tracks driving distances, manages follow-ups, and documents declined quotes. Customization options include logos, colors, and bilingual support for English and Spanish.

ObraSmart Pro

ObraSmart Pro is cloud-based software that helps construction and renovation professionals — contractors, remodelers, and small construction businesses — create professional budgets without spreadsheets or manual pricing. Estimates can be generated through a WhatsApp conversation, a voice message, or the web chat. The conversational AI assistant, BertIA, turns a description of the job — spoken, typed, or sent as photos or plans — into a detailed estimate structured into chapters and line items, in minutes rather than hours. BertIA keeps a running memory of each account: preferred margins, common materials, recurring clients, and past corrections. The system learns from every user's own historical pricing data over time, so estimates increasingly reflect that professional's real rates and margins instead of generic averages, and repeat work gets faster the more the account is used. ObraSmart Pro also includes integrated invoicing, with support for Spain's VeriFactu framework, so a validated estimate can be converted into a compliant invoice without leaving the platform. Invoices and estimates are delivered as professional, branded PDFs ready to send to the client, and both are kept in a searchable history. For teams that also handle floor plans, ObraSmart Pro includes an AI-assisted 2D plan and render generator: upload a hand-drawn sketch with real measurements, and the system produces a scaled floor plan and a visual render of the space. ObraSmart Pro is built specifically for freelancers and small businesses in the renovation and construction sector. It is used primarily in the Spanish market, with expansion currently underway into Latin America. The product is delivered as a web application, accessible from any browser, with WhatsApp as an additional channel for creating and managing estimates on the go — no separate mobile app installation required. An administrator dashboard gives an overview of budgets generated, invoices issued, and how much of the AI assistant's memory has been trained for that account.

PaintWorkz Pro

Spray shop software built for cabinet and joinery finishing businesses that paint doors, panels, drawer fronts and custom parts in 2 pac. Jobs are measured part by part with single side, double side or edge return painting, and the square metre total calculates instantly. A pricing matrix by door profile and finish turns each job into an estimate, quote or invoice, with colour surcharges, delivery, freight and Cut To Size board supply and edge routing. Paint formulas are stored with base codes and tinter amounts and scale automatically to the litres required, so a repaint months later uses the exact same mix. A paint stock ledger tracks base litres and tinter grams and deducts stock as jobs are completed. A Gantt style schedule shows sand, undercoat, topcoat and completion phases across all active jobs. Ten printable forms are generated from the same job data including supply dockets, mixing cards, part labels, cover sheets and paint orders. Reports cover square metre throughput, top colours and profiles, client breakdown, turnaround days and estimated margin. Staff logins with a PIN keep pricing hidden from the shop floor. Units, currency and tax rate can be set for Australia, New Zealand, the United Kingdom, the United States and Canada. Data syncs across devices and the app keeps working if the signal drops, catching up once back online.

PreConstruct AI

PreConstruct AI is takeoff and estimating software for subcontractors bidding commercial work — drywall and interiors, concrete, and wood framing. Upload the drawing set. It reads the text on every sheet — schedules, notes, room finishes, wall types — and puts what it found in a review queue. Each item links to the exact spot on the sheet it came from, and anything doubtful is flagged rather than guessed. You draw the walls, or check and confirm the ones it suggests (a beta on every paid plan), pick a wall type once and apply it to as many walls as you need. Every material comes out with its arithmetic printed beside it, so you can see how a number was reached before you stand behind it. Price from your own supplier quotes and labour rates, set waste, burden and markup, then generate a proposal your client opens in a browser and accepts by typing their name. Accepted proposals can be sent to QuickBooks Online as estimates (beta). Quantities in imperial, metric or both. The first bid is free, with no card. It would rather miss than be confidently wrong.

Priceguide

Priceguide is an online pricing estimator for home service contractors and franchise networks. A business adds an interactive estimator to its website. Homeowners answer a few simple questions about their project and get an instant price range. The business receives the homeowner's contact details and project scope before the first phone call. Many homeowners want a rough idea of cost before they talk to a contractor. Priceguide gives them that range online, at any time of day, without waiting for a site visit or a callback. The business gets a lead who already knows the likely cost, so sales conversations can move faster and focus on the details of the job. Setting up an estimator starts with the business's own services and prices. Priceguide's AI can write the questions for each service, and the business sets a price range for each answer. Estimators use the business's own colors and logo. On some plans, conditional logic shows or hides questions based on earlier answers, and Pricing Lab tests prices across many scenarios and flags problems to fix. Priceguide includes tools made for home service work. Satellite area measurement lets a homeowner enter an address and measure a roof, lawn, pool or driveway straight from a map. Large estimates can be shown as monthly payments, with the business choosing the payment terms. The results page text can be edited, and homeowners can change their choices after they see a price. Price ranges are also shared in a format that Google and AI tools can read. Each finished estimate sends an email alert with the homeowner's contact details, and a dashboard shows the services chosen and the price ranges given. Leads can flow into other tools through Zapier, Jobber, JobTread, HubSpot, ServiceMinder, GoHighLevel and GA4. For franchise brands, Priceguide sends each homeowner to the estimator for their local location based on ZIP code, so every lead reaches the right territory. Headquarters sees results for every location on one dashboard, while each location sets its own local pricing within limits the brand controls. Priceguide supports many trades, including roofing, HVAC, painting, plumbing, windows and doors, landscaping and outdoor living, pools, flooring and home remodeling. More than 2,500 home service businesses use Priceguide, and it has delivered over 175,000 homeowner estimates.
