Don't Forget: You're a Designer _ must be professional Imagine this, you're at an expensive restaurant. Every detail is perfect: the food was fantastic, the service excellent and the atmosphere rich and plush. Then, you receive the bill, which is printed on cheap paper with low_quality ink. What would you remember about this experience? Most people spend hours on their website design, business cards and resumes but then use a template for their invoice. The invoice is your last contact with your client, and it should share the attention to detail, branding and style of your other elements. By creating a beautiful, clear invoice, you are saying that you care about the little details. Most importantly, make sure you have all the necessary information. Make sure there are no spelling mistakes and that your spacing is consistent. Customize your invoice as much as you can. Your logo is a must, but colors and a style that match your other branding items will make it a joy to pay (well, as much as is possible).
Thank Them, and Ask Them to Thank You _ must be sincere Money is often a touchy subject, so politeness about it is a good idea. Your clients are paying you money that they've earned with blood, sweat and tears, so let them know you appreciate it. You should also invite them to contact you if they have any questions and, more importantly, make it clear that you appreciate their present (and future) business. Some people also welcome testimonials; for example, by adding, "Let us know how we did. Write a testimonial and sent to... " If you're building your website's testimonials page or want to complete the feedback loop, this is a great way to get clients to give feedback on your work. If they have suggestions for making the process smoother, it's also a great opportunity for you to improve.
