Construction Software Development Company

We build construction software that survives the job site โ€” project and site management, estimating and bidding, field reporting, and progress tracking that keep office and site on the same page.

Built for the site, not just the site office

Construction software fails when it assumes a desk and a stable connection. We build mobile-first field apps that work offline in basements and remote sites, capture photos and measurements quickly, and sync automatically โ€” so site engineers actually use them instead of reverting to WhatsApp and paper.

Connect estimating, execution, and cost control

Margin leaks between the estimate and the finished job. We connect estimating and BOQ, procurement, site progress, and actual cost so you can see budget versus actual per project in real time, and catch overruns while they are still fixable.

Compliance, safety, and an auditable record

Inspections, snags, safety checks, and daily progress reports need to be captured consistently and defensibly. We build structured, timestamped, photo-backed records with approval workflows, giving you an audit trail for clients, insurers, and disputes.

How much does construction software cost?

Cost depends on how many workflows you digitise and whether you need offline mobile apps. These ranges reflect typical engagements; you receive a fixed-scope quote after a free consultation.

Project typeTypical costTimeline
Single-workflow app (e.g. site progress reporting)$10,000 โ€“ $30,0005 โ€“ 10 weeks
Estimating / BOQ or bidding system$25,000 โ€“ $70,0002 โ€“ 5 months
Project & site management platform$40,000 โ€“ $110,0003 โ€“ 6 months
Offline field mobile app (iOS + Android)$18,000 โ€“ $50,0002 โ€“ 4 months
Full construction ERP with cost control$110,000 โ€“ $300,000+6 โ€“ 12 months

Ranges are indicative and vary with integrations and site count. Starting with our ready construction products and extending them is typically faster and lower-risk than a ground-up build.

Flexible engagement & pricing models

Every business is different, so we offer several ways to work together. Start with a free consultation and we will recommend the model that best fits your scope, timeline, and budget.

๐Ÿ“

Fixed-scope project

Best for well-defined builds. We agree scope, timeline, and a fixed price up front so you know exactly what you get and what it costs.

๐Ÿ‘ฅ

Dedicated team

A cross-functional squad โ€” engineers, designers, QA, and a project lead โ€” that works as an extension of your business, month to month.

๐Ÿ”ง

Staff augmentation

Add senior developers or AI specialists to your existing team to fill skill gaps and accelerate delivery without long hiring cycles.

๐Ÿ”

Support & retainer

Ongoing maintenance, optimisation, and new-feature development on a predictable monthly retainer after launch.

Our delivery process

1

Discovery & strategy

We map your goals, users, and workflows, then define scope, architecture, and a clear roadmap with fixed milestones and transparent pricing โ€” no surprises, no scope creep.

2

UX design & prototype

Wireframes and interactive prototypes validate the experience and de-risk the build before a line of production code is written, saving you time and budget.

3

Agile development & QA

We build in two-week sprints with continuous integration, automated testing, and live demos, so you see working software early and steer it as it grows.

4

Launch, support & scale

We deploy to the cloud with monitoring, security hardening, and CI/CD, then iterate with analytics-driven improvements and ongoing support as you scale.

Frequently asked questions

Will the software work on site without internet?

Yes. We build offline-first mobile apps that store data locally and sync automatically when connectivity returns โ€” essential for basements, remote sites, and poor coverage.

Can you build estimating and BOQ software?

Yes. We build material and labour estimating, bills of quantities, rate analysis, and bid preparation tools tailored to how your team prices work.

Can it integrate with our accounting or ERP system?

Yes. We integrate with accounting, procurement, and ERP systems through secure APIs so cost data flows without duplicate entry.

Can we track budget versus actual cost per project?

Yes. We connect estimates, procurement, change orders, and site progress so you see real-time budget versus actual and catch overruns early.

Do you have ready construction products?

Yes. ZetsApp offers construction products including Relina Onsite, Estimate Pro, and BuildBoard, which can be deployed quickly and customised to your processes.

How much does construction software cost?

A focused single-workflow app typically starts near $10,000, project and site management platforms run roughly $40,000โ€“$110,000, and full construction ERP costs more. We quote fixed scope after a free consultation.
