We started in 4,500 sq feet but it was very cost effective although it did not seem it at the time. I always was able to see more business coming and we would get more space before we needed it. I was lucky in that we were taking over additional 4,500 sq ft units in a multi-tenant building so it was easier. If you can't see more business coming I would say take more space when you cannot produce any more in the space you have. In over 20+ years we went from 4,500 to 9,000 to 13,500 to 18,000 to 20,500 and then we bought a 60,000 sq foot building. The building cost less monthly than the 20,500 sq foot rental space. Read that sentence twice, it is important. It is also an appreciating asset that you can depreciate.
There seem to be two types of businesses on this forum. Businesses that want to stay smallish and businesses that want to grow to their full potential.
If you are the stay small guy I would say, be very cautious, controlling expense is very important.
If you are a grow to your full potential person I would say try and buy space when you are ready that you can grow with. Meaning you will continue to grow so buy something you can add on to is important.
Finally, most people on this forum are more of a technical
cabinet maker engineer type person. If the business end makes your head spin, as you grow you can hire a general manager / sales manager type person. Don't fear the growth. The business with the best team wins. Try and surround yourself with a great team. Hopefully they are better than you at the task they are doing. I can honestly say that a 5-person company is harder to run than a 20-person company and a 20-person company is harder to run that a 40-person company. If you are imaging a 40-person company and you are responsible for everything you are responsible for now you would never try and grow. If you do it right, it will not work that way.
Enjoy the journey, it should be fun.
