Thanks for posting that, it's interesting, but what exactly was the point? $500 or ~%25 margin over retail cost is actually pretty low. From a business perspective, dealing with faulty parts, labor to build and burn-in these machines, the cost maintaining a website, will easily eat up the difference. The real expense however, comes from having to support your customers and warranties. I sell custom PCs to small businesses and I can tell you that supporting some of them who call over the smallest issues that aren't even related to the build (mostly 3rd party software issues) is a burden. I only get paid when I sell the machine, and I warranty it for 1 yr. My margins to provide that service are a lot higher than 25%. After business taxes alone, if I only charged 25% I'd lose money.
I think a lot of people have no idea what it actually costs to run a business.
In Maryland for instance, just ongoing costs:
2.3% of each persons payroll (for new non-construction companies) to unemployment ins tax, paid by the company, not the employees,
7.5% of payroll in SS/MED taxes paid by the company in addition to 7.5% paid by employees.
$252/yr in payroll fees,
$720/yr in bank account fees (if less than $150k avg balance)
$450/yr for tax prep
$300/yr to maintain company LLC charter
~$1000/yr in webhosting
$1800/yr in phone bills
$840/yr in internet service
~25% in additional state and federal taxes on net income after the above business expenses are accounted for.
If you are small enough, the affordable care act doesn't apply, so I don't have a figure for that, but that starts today.
The add-on expenses are endless. I can't tabulate them all here, but from my perspective 25% margin is an excellent deal.
