Transparency
Every line, every signature, every approval is traceable; the audit trail is never erased.
About
The right math, billing on time.
Kesinfiyat was founded to bring progress billing, price adjustment and approvals together in one panel for contractors. Our team comes from finance, software and site operations. We know the problem from the field, not from a desk.
Our mission
What we do and why
In Turkey, progress billing is still prepared by hand in spreadsheets. Price adjustments use the wrong index, deductions get forgotten, approvals get lost in email, and every mistake resurfaces at audit time.
Kesinfiyat moves the whole calculation into the system. Field measurements become the green book, the green book becomes the cover sheet, the cover sheet becomes an approved payment. Who changed what and when is all on record.
Values
How we work
On time
When the math is automatic, billing takes minutes, not days.
