Let Them Know How to Pay You _ must be easy Do you want a cheque mailed to you, a money transfer, flowers? Be explicitly clear about what you expect and in what form. It is usually best to discuss with the client beforehand their preferred method or to come to an agreement about a method you both like. If you want a money transfer, provide all the necessary information. Foreign transfers need more than your account number: in some countries, you need your International Bank Account Number (IBAN) or a Bank Identifier Code (BIC). International transfers also double_charge you: the client's bank might charge you ฤ, and your own bank might charge you another ฟ to accept the payment. Make it clear which of you will absorb these charges, and talk it out with them. PayPal is another option, but you still get charged a percentage of the transaction.
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.
