i run a restaurant. customers book tables by phone and I write them in a notebook and the system is broken now. i switched to Ecel but it's still messy... i need software.
i can code PHP (hobby level), maybe I could build a system that works for two-three months. but it's not professional maintenance would be hard and is it more expensive than an open-source program worth millions?
should I outsource it, or just do it myself? what should I prefer in terms of rental costs compatibility and integration?
