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.
Bulk purchases not tracked
You buy cement or tiles in bulk for RM 8,000 but can't tell which projects consumed what. You either over-charge one client or absorb the cost yourself.
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 from purchase to profit — and a built-in way to grow your business with new leads.

Purchases & Expense Tracking

Know exactly what
you made on
every project.

Most Malaysian contractors finish a job and don't really know if they made money. KonstrakOS closes that gap — without turning you into an accountant. Just record what you paid. We'll tell you what you kept.

Record Supplier Bills in Seconds
Bought cement, tiles, or pipes? Log the supplier name, amount, and date. Attach a photo of the receipt. Done. No accounts knowledge needed — just five fields.
Bulk Purchases Across Multiple Projects
Bought RM 10,000 of tiles for three jobs? Record it once at business level, then allocate portions to each project. The unallocated balance stays visible until every sen is assigned.
Track Labour & Subcon Payments
Paid workers in cash today? Log it in 30 seconds — date, description, amount. Subcontractor submitted a claim? Record it against the relevant stage. Everything ties back to the project.
Your Real Project Margin — Always Visible
KonstrakOS adds up everything you collected and everything you spent, then shows you the number that matters: what you actually made. No spreadsheet, no calculator, no accountant required.

Security & Your Digital Presence

Your data is safe.
Your business is visible.

KonstrakOS protects every ringgit of your project data with bank-grade encryption — and gives your business something most Malaysian contractors don't have: a professional online presence.

Data Protection

Bank-grade 256-bit
encryption. Always.

Every piece of data you store in KonstrakOS — your project costs, supplier bills, client details, invoices, and site records — is protected with AES-256 encryption, the same standard used by banks and financial institutions worldwide.

AES-256 Encryption at Rest
All stored data — BQs, cost records, supplier bills, client contacts, invoices — is encrypted at rest. Even if a server was ever physically accessed, your data would be unreadable.
TLS Encryption in Transit
Every connection between your device and KonstrakOS is secured with TLS. Data moving between your phone or laptop and our servers cannot be intercepted or read by third parties.
Automatic Cloud Backup
Your project data, expense records, and purchase history are backed up automatically. No more risk of losing years of work to a crashed laptop or a lost phone.
Your Data Is Never Sold
KonstrakOS does not share, sell, or monetise your business data. Your project costs, supplier list, and financial records belong to you — full stop. Read our Privacy Policy.
Digital Presence

Your contractor mini-website,
ready in minutes.

Most Malaysian contractors get jobs purely through word-of-mouth — with no website, no Google presence, and no way for new clients to find them. KonstrakOS gives every contractor a free, professional landing page to change that.

FAQs

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.

Is my data safe if I close the browser?

Yes. KonstrakOS saves your data to the cloud. Professional and Enterprise plans include automatic cloud sync so you can access everything from any device — phone on site, laptop in the office.

How does expense tracking work?

Inside any project, go to the Expenses tab and log what you paid — date, type (Labour / Subcontractor / Material / Other), description, and amount. Optionally attach a receipt photo. KonstrakOS adds it to the project's actual spend total automatically and updates your margin in real time. No accounting knowledge needed.

What is a bulk purchase and how do I use it?

A bulk purchase is a supplier bill that covers materials used across more than one project — for example, buying 500 bags of cement that will be split between two jobs. You record the purchase once at the business level (not inside any one project), then allocate portions to each project as the materials are consumed. The unallocated balance stays visible until every sen is assigned. Available on Professional and Enterprise plans.

How does the free plan differ from Professional?

The free plan gives you up to 5 projects, BQ, cost tracking, invoicing, quotes & proposals (CIPAA T&Cs included), site checklist, site diary, item library, and basic CRM. Professional unlocks unlimited projects, expense tracking, bulk purchase management, the project margin dashboard, CIPAA claims module, PDF/Excel export, contractor profile, advanced reports, and up to 5 users.

Can I import my existing Excel BQ into KonstrakOS?

Yes. KonstrakOS supports importing existing BQ files so you don't have to start from scratch. You can also export your data back to Excel or PDF at any time.

How does the contractor profile / lead generation work?

Set up your public contractor profile with your company name, services, portfolio, and WhatsApp number. Share your unique profile URL on social media or in your email signature. When clients find your profile and enquire, the lead appears instantly in your KonstrakOS dashboard for you to follow up.

Can I upgrade or cancel anytime?

Yes, completely. Upgrade from Free to Professional whenever you're ready — no lock-in contract. Cancel Professional or Enterprise at the end of any billing period. Your data is always yours and never deleted when you downgrade.
