Every penny accounted for, every decision on record.

In Turkey, progress payments are still mostly prepared in hand-built Excel spreadsheets. The price adjustment reads the wrong month's index, a deduction gets forgotten, an approval gets lost in the correspondence. The bond's expiry, the advance recovery and the legal limit on a contract amendment sit in separate files, with separate people. Every mistake surfaces for both sides at the final account or at audit.

Kesinfiyat brings all of it into one ledger. The measurement on site becomes the green book, the green book becomes the progress payment cover, and the cover goes through the approval chain to become a payment record. Who entered it, who approved it and who sent it back is on record. Our team comes from finance, software and site operations; we know the problem from the field, not from a desk.
