Access Fonn – Project management in your pocket 

Access Fonn is the mobile-first construction site management software that’s built for those who actually build.  

Fonn on mobile and desktop makes sure everyone on site and in the office is working from the same page. No more WhatsApp threads. No more chasing paperwork. No more defects piling up before handover. 

“Every project that we've run through Fonn has finished on time. That's not by accident.”

Built for the build - From first fix to final handover

Access Fonn gives every person on every site - and every manager in the office - what they need to keep projects moving. No firefighting. No version chaos. No chasing. 

Coordinate - Field and office automatically in sync

Wrong drawings lead to expensive rework. Fonn eliminates this before it happens with integrated version control.

Control - Prove who saw what, and when

Every action is timestamped, giving you the evidence to resolve disputes fast.

Deliver - Projects finish, without the firefighting

Track progress, generate daily reports and clear snags before handover.

  • Digital forms and compliance, including NCC inspections 
  • RFIs and submittals

How long does Access Fonn implementation take?

Access Fonn goes live in 7 working days.  

  • Day 1 covers account setup and project import.  
  • Days 1–3 cover drawing upload and configuration to your project types.  
  • Days 3–5 cover site manager onboarding - typically 2 hours to full competency.  
  • By day 7, your first site is documenting in real time.  

There’s no large IT project, no change management program, and no dedicated administrator required.  

If your site team can use a phone camera, they can use Fonn.

Can we migrate our existing project data into Access Fonn?

Yes. Your existing drawings, project structures, and documentation can be imported into Fonn as part of onboarding.  

Fonn also integrates with leading construction ERP platforms - your onboarding team will confirm the best approach for your existing systems.  

Our onboarding team will work through your existing data with you during the 7-day go-live process.

Does Access Fonn integrate with other software?

Access Fonn includes an open public API for easy integrations with popular project management, document management and accounting tools.

How is Access Fonn priced?

Access Fonn is priced as a flat annual fee - not per user, per subcontractor, or per project. Every subcontractor and trade worker on every project is included at no extra cost.  

All Access Fonn packages include document and drawing management, defect management, task management, reporting and Scope of Works/WBS. Additional modules are then included at extra cost. 

Do we need to train our site workers to use Access Fonn?

No formal training program is required. Access Fonn is designed to work like the apps site workers already use - its interface follows the same patterns as WhatsApp and other consumer apps.  

Most site managers are competent users within 2 hours.

Stop building from yesterday’s drawings. Your first site could be live before the end of next week.
