Hello! This is a great question and I wish many more asked just like you. My name is Humberto Valle, I'm a strategic marketer with almost 10 years of service with some of the most innovative teams in the world.
Here are my thoughts; I would ask for a bit more information, don't be afraid or shy to share more about your company, goals, mission & vision statement. The tag line can be a simple as 2 words or as long as a sentence as long as it makes sense to your target market.
If you pay attention, there are a lot of companies which taglines don't even mention the service or product but instead focus on empowering their mission statement or core experience from using the product specially if your company name, logo, or website already mention the product you can drive your goal home with the tag line.
Example:
having a playful company profile and the name Paperless Wiring, inc. you could go with a playful tagline like:
Easy Messaging Galore or Hand Picked Just For You.
But if your profile and core is more professional and buttoned up, then your tag line should match that and help drive that style home with your clients; examples:
Reliability at its best, tailored services just for you.
if you are a local company trying or wanting to leverage your origin consider using slang or accents that emphasize that. I think it was the KFC slogan that's a good example of this with their lickin' good.
