Why I Built IronMargins

Before writing a single line of code for this app, I ran my own custom furniture crafting business. I know exactly what it feels like to win a bid, finish the job, and realize that hidden labor burdens and material waste completely ate your profit.

I built IronMargins to solve my own bottom-line problems because the existing software out there was bloated, expensive, and built by tech companies who have never swung a hammer or worked in a shop.

When you use this software, your data is backed by enterprise-grade security and you own it all via CSV exports. But when you have a problem or need a feature, there are no corporate phone trees. You email support, and you talk directly to me.
