Numbers and Numbers and Records and Books _ must be trackable Referring to "invoice #9048," rather than "That invoice I sent you last month, I think on a Tuesday," is much easier to track for both you and your client. Assign numbers to your invoices systematically, consistently and chronologically. Some people number their invoices by year (for example, 2009043 would be the 43rd invoice of 2009). You could also specify a code for the project. For example, ABC06 would be the 6th invoice for the ABC project that you're currently working on. Having an invoice and project numbering system keeps everything in line.
Benefits of Implementing Electronic Invoices (e_Invoices or eBills) _ Depending on a company's volume, the savings related to invoice management (receipt, storage, search, signing, returning, payment, shipping, etc.) can fluctuate between 40% and 80%.

Decreased possibilities for falsification. Easy access to the information. Reduction in the space required for storing archival documents. Quicker and more efficient administrative procedures
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.
