If you ever need a made-up business name for your screenplay or novel (e.g., the company for whom your protagonist works), try using the Oberlo Business Name Generator (it's free). All you have to do is type in one word you want included in the business name. For instance, let's say that I want my protagonist to run a barbershop. Here are some of the names the generator came up with:
Paramount Barbershop
BlueRibbon Barbershop
Deuce Barbershop
Mainline Barbershop
Barbershop Island
Luxury Barbershop
GoodLife Barbershop
Freestyle Barbershop
Perfection Barbershop
Brilliant Barbershop
Progressive Barbershop
LET THE NAME MATCH THE SETTING OR TONE OF YOUR STORY
Once you have a good selection, narrow the choice by considering which ones best match the setting or tone of the story. A sci-fi story might feature a "Galactic Barbershop," while a noir-type story would be better served by "Deuce Barbershop" and a comedy might find material in the difference between the aspiration suggested by "Perfection Barbershop" and the lack of that perfection in actuality.
CAN YOU USE AN ACTUAL BUSINESS NAME?
When you find one you like (examples below), Google it to check whether it actually exists.
It's OK to use a business name that is common--for instance, I'm sure there are plenty of "Curl Up and Dye" salons. But avoid that if you have set your story in a real location and that business name is in use in that location.
Be especially careful if your fictional business is dishonest or disreputable!
