Built around your business. Not the other way around.
Every system is fully bespoke; scoped, structured, and built around how your business actually works. For residential and commercial builders.
From $900— Discovery session, credited toward your build How it works
A bad system costs more than no system at all.
Most builders buy software, watch a few tutorials, and six months later they're back to doing it the old way. The problem isn't the software. It's the system behind it. That's what we build.

Your business is unique. Your system should be too.
Discovery Session
$900 · 1–2 hours · credited toward your build
We spend a focused session understanding your business inside out. How you quote. How you order. How your team communicates. Who your suppliers are. Where time gets lost. Where money leaks.
Custom Build
Scoped and quoted after your discovery session
Based on your roadmap, we build your system from scratch. This could include estimating templates, scheduling tools, supplier integrations, ordering workflows, team dashboards - whatever your business actually needs.
Handover & Training
We don't just build it and leave. We walk your team through every part of the system, make sure everyone's comfortable, and provide support as you bed it in.
No two systems look the same.
Campbells supports the volume, complexity, and reliability needs of modern building businesses.
Estimating Templates
Pre-loaded with your trades, specs, and supplier pricing.
Scheduling & Project Management
Job timelines, task tracking, milestone management.
Supplier Integrations
Live pricing feeds, automated ordering, approval workflows.
Team Workflows
Role-based access, quoting pipelines, approval chains.
Reporting Dashboards
Real-time visibility on job costs, margins, and pipeline.
Document Management
Plans, contracts, variations. Organized and accessible.
For builders ready to run their business properly, not just survive it.
Systems are the right fit if you've outgrown spreadsheets and disconnected tools, and you need a single, integrated setup that actually reflects how your team works. Whether you're residential or commercial, running a crew of 3 or 30, the system is built to your scale.
- You're quoting regularly and losing hours to manual setup every single time
- You've outgrown spreadsheets and need a system that actually reflects how your team works
- You run Wunderbuild or Buildxact, or you're open to moving to one
- You want your trades, suppliers, and specs pre-loaded from day one
- You're residential, commercial, or both, and you're ready to quote with confidence
- You only quote a handful of jobs a year and manual quoting still works fine
- You're not ready to invest in a proper setup ; you just want something quick and cheap
- You want everything handled for you with zero involvement in your own system
- You're still deciding which platform you want to build on
- You need something live overnight; a proper system takes days to set up right
Custom Systems Build
How It Works
Custom Systems work begins with a $900 session. How you start depends on where you are. If you already know you want a custom system built and just need it scoped, book a Systems Discovery Session, the first step in your Custom Systems Setup. If you're earlier in your thinking, exploring options, weighing software, or wanting expert eyes on your current setup before deciding anything, book a Systems Audit & Advisory. Either way, the $900 is fully credited toward your custom system setup if you proceed.
What You Walk Away With After Discovery Session
- A detailed scoping document for your custom build
- A tailored roadmap covering structure, tools, and integrations
- A clear, fixed quote for your custom system
- Software platform recommendations with pros and cons
- Full credit toward your system build if you proceed
Why Start Here?
Most builders waste weeks going back and forth trying to figure out what they need. This session compresses that into 1–2 hours with someone who's built these systems hundreds of times.
- Clarity on what your system should look like
- No obligation to proceed after the session
- $900 fully credited if you go ahead with the build
- Honest recommendations; not a sales pitch
- Covers Wunderbuild, Buildxact, and other platforms
Testimonials
Real builders, real results.
Here’s what builders shared about their experience working with our team.
"We’ve been working with Jacob and his team for our pre-construction estimating, and they’ve been outstanding." Not only have the estimates been accurate and well thought out, they have also been incredibly helpful in guiding us through Wunderbuild and improving how we use the platform day-to-day.
Time and again, Campbells Estimating delivers precise, detailed, and thoroughly prepared estimates, giving us complete confidence in our project planning. We wholeheartedly recommend Campbells Estimating and look forward to continuing this successful partnership for many projects to come.
Jacob's precision, professionalism, and efficiency are second to none. Adding to that his team at Campbells Estimating follow by his example. The Buildxact training and integrated add-in support he provided have streamlined our estimating process and lifted our workflow to another level. Jacob’s expertise has been invaluable — I’m a customer for life.
Really impressed with Campbells Estimating Services. The team was friendly, fast, and incredibly thorough. They took the time to explain everything clearly and made sure I understood all the costs involved. Their estimate helped us make informed decisions and avoid surprises. Fantastic service and great people.

If you have any questions, just book a 15-minute call with us . No hard-selling, no pressure.
It's a structured, 1–2 hour working session where we map your current workflows, tools, suppliers, and pain points. You'll leave with a scoping document and a recommendations roadmap - whether you proceed with us or not.
No. The $900 covers the session itself and the deliverables you walk away with. But if you do proceed with the build, the full $900 is credited toward your project cost.
Placeholder answer for the third question. Match the length and tone of the others for consistency.
Yes. We work across 20+ platforms including Buildxact, Wunderbuild, Databuild, Cubit, SimPro, Buildertrend, ProCore, and many others. If you're already using a tool, we'll build around it, not replace it.
Absolutely. Every system build includes a full handover and training session. We make sure your entire team is confident using the system before we step back.
We offer a Technical Support Service at $35/month, which covers ongoing technical support: bug fixes, troubleshooting, platform updates, and general assistance. Post-build tweaks and customisations are priced separately, scoped on consultation depending on what you need.
