Put a client service system in place. I used to teach this to financial advisors. The data we collected showed people increase their business with you the more you stayed in contact with them. Have a monthly newsletter or sending them a card of thanks or to congratulate them or wish them Happy Birthday will not only build a better relationship with your clients, but it will also increase the likelihood they will refer you.

Speaking of referrals – Thank you clients for every referral with a Thank you Note or Card and perhaps a discount on their next pet sitting appt. I thank my client referrals personally in my newsletter. People love this!
