Under promise over deliver. Now, this does not mean promise to do a worse job up front and deliver a fantastic job in the end… That might get you in trouble. What I mean by this is that you don’t set yourself up for failure. If you make an educated guess of a project being done in five days tell them seven days. Why!? A couple things can happen. Maybe you do can’t get the job done in time and it does take time you allowed as a buffer. Or even better, you get it done in five days and now the client is extremely happy with you for making them a priority and getting the job done quicker. It is up to you to determine how you use this tip. Make sure you don’t stretch things to far to make yourself look like a hero. Some people can sniff right through that B.S.
For each product you sell or service you render find a way you can offer more value to the client then they are paying you for. This helps create loyalty and possibly more business in the future. Example: When I have time I like to make recap videos for photo clients and take stills for video clients.
