Pretty good first post there Paul. WELCOME to the forum.
You're completely right. It can be a real discouragement when you have jumped through all the hoops to get a business license, contractors license, EIN #, TPT #, incorporate, insurance, bonding, and all the rest just to get started.
Then, you start looking at WPS's, welders certs, maintaining continuity, qc program, safety program, employee training, getting MTR's on all incoming materials, record keeping, more office staff than welders to keep up with all the nonsense.
Does it guarantee quality? NO!! Does it improve the odds that quality will be a higher priority than with the shop that doesn't go through all this? YES!!
And, at least in my area, it will get you jobs that others can't do when the local building authority finds out they don't have what it takes. It will also cost you less to play catch up when those same authorities start putting codes and the subsequent inspections into place because of insurance companies, banks, and other interests putting pressure on them because they are trying to protect 'their' (the banks and insurance companies) investments. You don't really think you own your house, business, etc do you? And they want it protected. That means from the moment it starts in engineering, then ground breaking, till done.
In many parts of this country the locals are so far behind. There are many things a company can do without all the high end, costly qc. But even if you work in one of those areas you can't get the good jobs, major contracts, without those qualifications.
Off my soapbox for now. Hope you enjoy this site.
Have a Great Day, Brent
