Finance and accounting decision
Puantaj Defteri
A small, production-useful replacement (web app + Postgres) is realistic for one capable developer to build and maintain in about a week; no durable moats are evident in the provided product pages.
View on the App Store↗Not priced
No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Puantaj Defteri alternatives, with the arithmetic →
What a replacement has to do
- Allow users to create employees, enter daily timesheet rows (calendar UI), calculate payroll (wage/overtime/advances), and export payroll reports as PDF/CSV.
What it still won’t have
- Native iOS App Store distribution and in‑app purchases (App Store presence)
- Phone live support line
- Existing app-specific UI polish and ongoing App Store updates
- Any proprietary company account management and logo/proposal PDF customizations provided by the app
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Puantaj Defteri does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal web-based timesheet & payroll app using Node.js (Express), PostgreSQL, and React. Core features in scope: user sign-up/sign-in, company and employee CRUD, calendar-based timesheet entry with bulk edits, payroll calculation engine supporting hourly/overtime/commission/unit/advance adjustments, PDF and CSV export for weekly/monthly reports, and a simple support/contact link. Out of scope: native mobile apps, App Store in-app purchases, advanced branding/custom proposal generation. Include server-side validation, error handling, tests for payroll calculations, and Dockerfiles for deployment.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 5 cited sources+3
- Evidence score86
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
