Why not an off-the-shelf order system
Off-the-shelf order systems work well if your company works like most others. Trouble starts with the exceptions: an order split between two workshops, approval above a certain amount, special prices for regular customers. The software either can’t do it, or you work around it with a spreadsheet again.
A custom system does only what you need and uses your own words for things. People learn it quickly and actually use it, which is what matters most with business software.
If an off-the-shelf tool is enough for you, we’ll tell you during the consultation. There’s no point paying for development of something that already exists.
