I try to always think "what else?" If I`m sending an invoice, can I add something? Sticker, special thank you of some kind (book mark), or just a handwritten positive comment.
When presenting, I always take something to give to one or more attendees, if not every attendee.
I contact clients when I don`t want anything but to say hello and wish them well.
I clip articles pertinent to them or what they do and send it with a short comment.
I try to assist in any way with things they are working on that have nothing to do with me or my business.
I never discount the little things as not making enough of an impact.
I try to always do more than expected.
