Sound Familiar?

Running a project
on guesswork is
costing you money.

Spreadsheet chaos
Multiple Excel files, no single source of truth. Formulas break, figures go out of sync — especially when you're managing several projects at once.
Projects blowing the budget
You only find out you've overspent when the supplier invoice arrives. By then it's too late to negotiate or cut back.
No leads coming in
Your work speaks for itself on site — but potential clients can't find you online. You rely on word-of-mouth and miss out on jobs.
Hours lost on paperwork
Writing quotations, preparing BQs, chasing invoices — all done manually, again and again, pulling you away from actual site work.

KonstrakOS fixes
all of that.

One platform. All your projects. Full cost visibility. And a built-in way to grow your business with new leads — all from your phone or laptop.

Real-time budget vs. actual cost tracking
Professional BQ creation in minutes
Digital site diary & checklist
Invoicing with PDF export

Common questions answered.

Do I need to install anything?

No installation required. KonstrakOS runs entirely in your web browser — on any device, any operating system. Just open the link and you're ready to go. No app store, no download, no updates to manage.

Is my data safe if I close the browser?
