What’s that blessing you say before engaging in commerce?

What’s that blessing that you say before engaging in commerce or business? As in, the blessing/prayer before you start work for the day.

I think that the text is in the Art Scroll siddur.

I need the Hebrew and English version.

Not sure if it’s called a prayer or blessing… but it’s the text that people have displayed artistically on plaques and such in their offices.

Been looking both online and in my Tefillas Hashem Hashem siddur for it, but have yet to find it.

Your help here would be greatly appreciated!!!!

Thank you 🙂
