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.
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.
Another outcome is an increase in efficiency; the AP department can instantly find an invoice without having to waste time chasing the business users. With approximately 70% of the invoices now matching the PO immediately, a considerable amount of invoices only require scanning, after which the process is entirely automated. This efficiency has directly resulted in a reduction in the number of people required in the Accounts Payable department; before the system was installed the team consisted of 13 people and there have been reductions in headcount, as the AP manager substantiates: "The IMS system has increased efficiency in our Accounts Payable department to such an extent that on full implementation we expect to reduce our headcount by 4."
