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.
Types of Electronic Invoices _ An electronic invoice is one which meets the same requirements that apply to invoices issued on paper, except that it is presented in electronic format and its authenticity and integrity are guaranteed. In order to guarantee a document's authenticity and integrity, there are three possible methods: Utilization of a recognized digital signature, which is based on a recognized certificate and generated using a secure device for creating signatures. Remittance through an "EDI" system, which ensures integrity and authenticity. Use of another system which, in the opinion of the Auditing Department of the State Tax Agency, ensures authenticity and integrity, whenever the taxpayer issuing the invoice has applied for Agency approval of the system in question. In general, the use of a recognized electronic signature is considered to be an essential element of electronic invoices.
Itemized List of Services _ must be specific People want to know what they've paid for. Most people will not pay for something described merely as "Design." Tell them exactly what they have received: e.g. "Design of three_page static website for Sporting Goods Department." Be as specific as possible. In five years, would both you and the client know what you meant by your description? Also, specify whether the charge is project_based or hourly. Include Your Terms _ must be clear When do you expect the client to pay you? What happens if they miss the deadline? To be able to send follow_up or overdue notices or to charge interest, you need a rock_solid paper trail that no one can argue with.
