At Transfutur, a transport and logistics company, I built an internal ERP from zero with PHP, MySQL and JavaScript. I was the only developer, and the system became part of the daily work of roughly ten people across two offices.
I worked directly with the owner and office users to understand what they needed for logistics, administration and invoicing. Then I built and deployed it. Getting the code into use was only part of my responsibility: maintenance, incidents, documentation and support stayed with me too.
The ERP handled invoicing of roughly €5–6 million a year. Accounting and operations had four people before the system and two afterwards. That staffing change gives some context for the work, without putting a measured efficiency percentage on the software.
At the time, a commercial alternative was quoted at around €18,000 for setup and migration, then €400–500 a month. That gave a concrete commercial comparison for the system I was building and supporting.
I ran and supported it for about a year. The company grew and eventually moved to a larger vendor's system. I am proud of this project because I took it from an empty starting point to software people relied on every day. I had to understand their work, make the system useful and keep it working after launch.
Project sources & checks
Self-reported Transfutur experience: custom logistics ERP, office and accounting automation, direct requirements work, deployment and support.
Two offices and approximately ten users. The original source code is unavailable.
Built from zero and operated and supported for about a year. Approximate annual invoicing of €5–6 million; accounting and operations staffing was four before and two after. These recollections are not a measured causal efficiency result.
Author-reported historical quote of approximately €18,000 for setup and migration plus €400–500 monthly. These are quoted vendor fees, not a net savings or ROI calculation.
