01Overview

Nettutar is where a construction company records every movement of money. Each transaction is linked to a category tree (head office, finance, construction sites) and to a project, so at any moment you can see what each site has spent on what and how much it has received in progress payments. The app was rewritten from scratch.

Problem

The company's finances lived in Excel files and paper ledgers. Foreign-currency payments, post-dated checks and per-site costs were each tracked separately, and working out the true cost of a single site took days.

Solution

Cash and bank transactions, current accounts and checks/promissory notes share one data model. Every transaction is stamped with that day's Central Bank exchange rate, so amounts are tracked in TL, dollars and euros side by side. The income-expense report cross-tabulates the category tree with site tags; overdue checks are processed every night and recurring current-account entries at the start of every month, automatically.

02How it works
