For owners and management
Answers you no longer have to wait for a recap to get.
Which projects are falling behind?
Planned and actual progress come from the same project data, not from weekly reports compiled again by hand.
Which projects are starting to squeeze the margin?
Cost plan, actual cost, and projected margin are visible while the project runs, not after it ends.
What needs to be billed and paid?
Progress billing, receivables, retention, supplier payables, and cash position are tied to each project.
How is the whole company doing?
Every project feeds the same management dashboard, with today's priorities at the top.

As projects multiply, scattered data gets harder to control.
With several projects running at once, management needs one source of data to see how projects and the company are doing, quickly.
Without one system
- Budgets in spreadsheets
- Progress sent over field chats
- Purchases recorded separately
- Costs compiled by each department
With Kurvas
- Less re-entering of data
- Consistent numbers across departments
- Faster project monitoring
- An easier audit trail and transaction tracing
Inside Kurvas
One system, from budget to financial statements.
Unit prices and budgets
Unit price analysis from the adjustable Ministry of Public Works AHSP library, versioned budgets (RAB), and cost plans (RAP) derived from them.
S-curve and progress
Plan and actuals on one S-curve, physical progress with photos, and daily reports from the field.
Procurement and materials
Material requests, purchase orders, goods receipts, and warehouse stock per project.
Cost control
Actual cost against the cost plan while the project runs, so margin pressure shows up early.
Finance and accounting
Automatic journals from goods receipts, bills, invoices, and payments, through to profit and loss, balance sheet, and cash flow.
Field teams and payroll tax
Field team attendance, with Indonesian income tax (PPh 21 TER, PP 58/2023) calculated from attendance data, including withholding slips.
A connected workflow
From planning to financial reports, the data stays in one place.
Project transactions and activity do not end up as reports passed between departments. Project, procurement, warehouse, finance, and management teams read the same numbers.
