Most Malaysian contractors don't lose money on bad pricing — they lose it to site changes nobody logged and materials nobody reconciled. Plug in your numbers below and see roughly how much of this project's margin is quietly leaking, based on how you're currently tracking it.
KonstrakOS lets you import your Excel BQ in 60 seconds, then tracks actual costs against budget in real time — so variations get logged the moment they happen, not forgotten by month-end.
We're not going to pretend this is an audit. It's a directional estimate built from leak patterns commonly seen in Malaysian trade and renovation projects that rely on manual tracking — meant to make an invisible problem visible, not to replace your actual books.
| Tracking Method | Typical Unbilled Variation Leak | Typical Material/Logistics Slippage |
|---|---|---|
| Excel / Google Sheets | ~2% of contract value | ~1.5% of material cost |
| WhatsApp Groups | ~4% of contract value | ~3% of material cost |
| Pocket Notebook | ~4% of contract value | ~3% of material cost |
| Just Memory / Verbal | ~5% of contract value | ~4% of material cost |
Longer projects add a small additional variation-leak allowance beyond 6 months, since verbal changes are more likely to be forgotten the longer a job runs. Your actual numbers will differ based on your team, your client, and how disciplined your current process already is — use this as a prompt to check your real numbers, not as a final figure.
