How to grow your business further...
Vamping up your marketing
Getting back to old school customer service
Following up with your customers
building feedback and referrals
Networking tools
Ironing out the bugs?
Improving production
Promotion tools - self branding - running a promo (ie branded pens, cups, diaries)
Trade shows - exhibitor or attend to network
Broadening your scope/branching out in other areas
something that I'm looking to at the moment which would be good (for me LOL) is Home office versus Office/Shop outlet - pro's and cons, associated costs (I'll be starting a post on this soon myself - after I finish looking around the forum and seeing what info is already about).
What about - upgrading merchant facilities, computer software to improve business?
Just some quick ideas that popped into my head.
