I just lost a banner project for (20) 4'x10' banners because some idiot out of Missouri is doing them for $75.00 ea.
Fun stuff. I think I will sell my printer and have that knucklehead do my printing.
I think this is the last time I'm gonna bring it up but here it goes anyway....the part in red is your problem, right there.
Just because you've got a printer does not mean you've got the right tools for that job.
How much does it cost you to run banners on your printer, then hem the edges, then add grommets, then reprint anything you've screwed up?
If I can sub-contract that order to someone who does nothing but crank out banners on a much bigger, better machine....who will send me hemmed and grommeted ready to hand to the customer banners and charge me less than $1 psf for them you can't do them in-house and do them cheaper.
Now, in your example that works out to about $1.85 psf. That's a little cheaper than we'd go but even at that you're about 90¢ psf over my cost....making him about $36.00 above banner cost per banner.
20 banners @ $36 = $720
Taking the order, creating the art, sending the file to the printer, getting them in, handing them to the customer, and cashing the check will take what? Two hours?
Sure, they should have been more....we'd have bid that at around $2.75 psf, but they still made decent money on it. Sure, somebody is about to chime in that they'd have charged $8 psf....the catch is that only a random fool of a purchaser will pay that much for a blank banner order
(go ahead, post your story of the customer who bought 20 banners from you for $18 psf)
It's just like doing one coro sign in vinyl and subbing 50 out to a screenprinter. You just can't do them yourself and be competitive.
