Here is a little list of a few business tips & tricks I have come across these past few months.
Paying Tax in NYS:
E-file! http://www.tax.state.ny.us/elf/elf_individual.htm - It's really easy and does the calculations for you
Etsy Fee Calculator - http://www.rolbe.com/etsy.htm
http://www.letsets.com/ - Etsy Tools
Paypal Fee Calculator - http://www.rolbe.com/paypal.htm
www.Ping.fm - Lets you update all social networks at the same time/same site
Ghost Fox- https://addons.mozilla.org/en-US/firefox/addon/2278 - a firefox add-on that makes your browser all text/blend in with everything else (for when you're "working")
Instead of going to the post office, if you have a scale you can mail things from home.
If they pay with paypal, there is a button 'ship now' and you basically just need the weight of the item. You can then drop off at the post office or even arrange a pick-up at your place.
https://www.paypal.com/us/cgi-bin/webscr?cmd=_ship-now - Lets you ship to someone using paypal, even if they didnt pay with paypal.
Anyone have any to share?
