ERP-CT started as a way to solve my own problem. I began working at my dad’s company in 2021, and like many small businesses trying to keep costs low, everything was done manually. Quotes, invoices, accounts, journals, and tax returns were all handled on paper, no digital systems at all. Things worked, but when Egypt introduced the electronic invoicing system. At first the process was painful and manual, so I started iterating: Excel, then Excel with macros, then Python scripts connected to Excel, then Grist. Each step reduced some friction but still required me in the loop. Eventually I decided the real solution was to remove myself completely, so I built a mobile app that automates the whole workflow, generating quotes, creating and digitally signing e-invoices, and submitting them through a dedicated server running at my house with fault-tolerance mechanisms. so now my 12 years old brother can do everything with 5 mins teaching.
