Had a recent conversation about asking for referrals, and here's a photo I got in my mail later that day:
It's a visual reminder, now posted in sight of the phone. Referrals are the easiest, least painful, most cost-effective way for you to bring in new business. When your clients are telling you how happy they are with your work, remember to ask them for their help as you build your business. There are a lot of tactics you can use to generate referrals, books on the topic, many scripts to try- but meanwhile, right now, would a postit help you remember to ask for a referral?
