Hi Toggles. I would say welcome to the forum, but I see you have been a member for a while.
Thats an excellent start
From reading the rest of the thread, I'm not sure whether you are intending to
a) run a plumbing business. As a complete non-sequitur, you happen to be female or
b) you plan to run a plumbing business, specifically marketing and promoting yourself as female, and hoping to gain competitive advantage from the latter.
If its the former, then you probably have some minor perception issues to overcome, and no doubt there will be a few thumbless flipwits who think they can increase their standing by belittling you, but nothing you wouldn't get in any of the male dominated fields.
If its the latter, I think that there are probably some great opportunities in areas where there are a large number of relatively well off, single women. I can see it working in (for example) south west London, but not so much in less affluent areas. With a bit of inventive PR, I bet you could get some free marketing from local press.
Notwithstanding the above, its the same pitfalls as every new start plumbing business:
1) Failing to understand the overhead of running a business and therefore underpricing work
2) Giving credit to people who you shouldn't give credit to, and being surprised when they don't pay
3) Not keeping on top of the paperwork - particularly invoicing and credit control
4) Not understanding the difference between cashflow and profit
I reckon 99% of all the bad debts we have ever taken come down to a combination of these factors.
They are the four horseman of the self employed businesspersons apocalypse.
Only if the quality of work was at least as high as my own.
Never eat yellow snow.
And if you have false teeth, dont sneeze when standing at a urinal. Although this one is probably of limited value to you.
You're welcome.
